Abstract:
Wetland or stagnant swamp refers to an ecosystem of inland water that is vulnerable to population decline. Kampung Nasem in Merauke has quite promising fish resources. This research aimed to determine the diversity of fish species found in Kampung Nasem of Merauke. The fish sampling was performed for three months, from September to November 2017 at three research stations by functioning digital camera, ruler and manual as tools for documentation, while tool for fishing used gill net in the size of 1, 1.5, 2, 2.5, 3 and 4 inches; casting nets and scoop net. Fish found in the field were preserved with 10% formalin for identification purpose in the laboratory. The observed biological parameters were species richness, diversity index (H’), evenness index (E) and dominance index (C). The research finding obtained 15 fish species richness coprising 11 native fish species and 5 introduced fish species. The value of H’ was classified into moderate while the uniformity value was high, hence the fish were spread evenly in each research site and no species was found with domination. In addition, the Tilapia (Oreochromis niloticus) and Glass (Agrammus ambassadors) were species to have sufficient widespread distribution and numerous presence of presentation within the three research stations.

Abstract:
The Cenderawasih Bay is a marine habitat for whale sharks (R. typus) which appear almost all year round. The appearance of this whale shark is triggered by various factors, including the food. Anchovy is one of the attractions for the emergence of whale sharks, so it is necessary to conduct genetic, biological and ecological studies. Anchovy has a small in size, making it difficult to identify morphologically. The purpose of this study was to genetically identify anchovy samples obtained from Cenderawasih Bay and compare the sequences with the GenBank database. The COI gene fragments were amplified by PCR method, using primer jg-LCO and jg-HCO. Sequencing is carried out from two directions, forward and reverse with the sanger termination dideoxy method. The resulting DNA sequence has a length of 669 base pairs encoding 223 amino acids. The results of homological comparisons with the NCBI and BOLD System databases show that this sample has similarities to the COI sequence of Spratelloides gracilis with a similarity number up to 99%. The results of the phylogenetic tree analysis showed that the anchovy samples from Cenderawasih Bay were in one clade with S. gracilis from Japan and separated from the clade of S. gracilis from the Red Sea, with a distance between clades is 0.104. This result is in line with the identification by homological comparison in the NCBI and BOLD System.

Abstract:
The mangrove forest is an environment that is very rich in nutrients and it becomes an important element for plankton growth. This article aims to determine the diversity and abundance of plankton species in the mangrove area. The method used in this writing is a literature study, by exploring written sources in the form of books, articles, journals, or other documents relevant to the problem being presented. The information obtained from the literature study can be used as a reference to strengthen the existing arguments. The results of the writing show that the abundance and diversity of plankton in mangrove waters are strongly influenced by the physical and chemical conditions of the water, local conditions, tides, zoning, and mangrove density. In general, phytoplankton from the Bacillariophyceae class dominate mangrove waters compared to zooplankton. A mangrove forest management strategy needs to be implemented so that it can function for organisms and the surrounding environment.

Abstract:
The waters of South Sorong have potential shrimp resources, including abundant banana shrimp (Penaeus merguiensis de Man, 1888). This study aims to obtain information about the morphometric characteristics and growth of banana shrimp in the fishing area around the waters of Kampung Bakoi, South Sorong Regency, West Papua Province. Data collections were carried out in June and October 2019 using descriptive methods with direct observation techniques. Based on the results of data analysis, it was found that the total length of shrimp caught in Bakoi Village was in the range of 10 - 26.8 cm and the most were caught measuring 15.2 cm to 16.4 cm. The model of the relationship between length and weight of banana shrimp in Bakoi Village follows the equation Log W= 1,630+2,659 Log (L) or the form of negative allometric growth. Analysis of the relationship between total length (Y) and carapace length (X) (including rostrum) and the relationship between total length and carapace length (Z) (excluding rostrum) obtained the best estimator models, each following the logarithmic equations L = -2,188 + 10,226 Ln(PK) and L = 4,439 + 9,201 Ln(PKt) respectively.

Abstract:
Indonesia is the biggest tuna exporter in Southeast Asia. With a high number of tuna catch, it is worried that the catch will decrease tuna population, specifically longtail tuna. To anticipate the decrease, there needs to be a conservation program to protect longtail tunas from scarcity. One method used to protect longtail tuna is by genetic conservation. The aim of this research is to understand the genetic and phylogenetic variety of the longtail tuna in Pabean Surabaya Fish Market. The polymerase chain reaction was used to amplify segment of the mitochondrial control region gene from members of these sample, used forward primer CRK 5’-AGCTC AGCGC CAGAG CGCCG GTCTT GTAAA-3’ and reverse primer CRE 5’-CCTGA AGTAG GAACC AGATG-3’. Based on the sequencing process, 28 out of 29 samples longtail tuna were analyzed successfully. The results of the 28 sample analysis of longtail tuna based on its genetic variety and phylogenetic tree reconstruction showed a haplotype variety (Hd) score of 1,00000, and nucleotide (π) variety of 0,1939. Genetic variety value showed that longtail tuna has great adaption capabilities toward environmental changes time to time. Phylogenetic tree reconstruction results showed 7 clades with a genetic range of 0,005 – 0,035, which shows that all samples are closely related. The results of this study can be used as basic information in forming regulations on longtail tuna sustainable management and genetic conservation.

Abstract:
Sources of activity in Dorei Bay come from the Sanggeng market, the Wosi market, the port, the PLTD (Diesel Power Plant), hospitals, hotels, and residential areas. The seagrass system has a function as a food provider, as primary productivity in waters, dampers the arrival of waves, a place for growth and development of biota and sediment traps. Research and information on the accumulation of heavy metals in seagrass, especially Cymodocea rotundata are still very limited, especially in Doreri Bay. This study aims to describe the accumulation of heavy metals in seagrass Cymodocea rotundata, including leaves, roots, and rhizome, comparing the accumulation of heavy metals in seagrass Cymodocea rotundata each location as well as knowing the pollution index of each location. The research was conducted in Doreri Bay, Manokwari, West Papua in August 2018. The sampling locations for Cymodocea rotundata seagrass were around the waters of Pelayaran, Wosi, Yankarwar, Anggrem, and Nusmapi Island. The results showed that the highest Cu concentrations were described from each location, which ranged from 18.75 to 28.64 (mg.kg-1), followed by heavy metal Pb ranging from 0.46-19.31 (mg.kg-1), then logm weight of Cd ranged from 1.11-4.97 (mg.kg-1) and the lowest Cr6 + concentration in each location ranged from 0.20 -0.52 (mg.kg-1). The percentage of metal concentrations in the roots and rhizomes is 50%, it can even reach 82.64%, namely Pb metal at Yankarwar Beach. Meanwhile, the metal concentration in the leaf area ranged between 17.36-50.00% and the highest proportion was found in Pb metal at the Pelayaran location and Cr6 + metal at the Wosi location. The calculation results of the Metal poluttion Index (MPI) for heavy metals Pb, Cd, Cu, and Cr6 + show that the highest heavy metal index of 5 locations is on Anggrem Beach and the lowest is at Pelayaran Beach

Abstract:
Kabori Lagoon is a lagoon located in Manokwari Regency, West Papua, where the water quality data is still very limited. Chlorophyll-a is the most important photosynthetic pigment for aquatic plants such as phytoplankton. The purpose of this study was to determine the horizontal distribution of chlorophyll-a based on the spatial data approach in the waters of the Kabori Lagoon. The study was conducted from April to May 2019. The sampling point was determined by purposive sampling at eight points for sampling of chlorophyll-a and water parameters including physics and chemistry (temperature, DO, salinity, brightness and depth). Measurement of physical and chemical parameters is carried out in situ. Chlorophyll-a analysis was carried out at the Laboratory of Water Productivity and Quality, Faculty of Marine and Fisheries Sciences, Hasanuddin University. Spatial data processing used ArcGIS 10.4 and Surfer 16 to create chlorophyll-a distribution maps and bathymetry. The results showed that the chlorophyll-a content in Observation I was in the range of 0.12-2.40 mg/m3 and in Observation II it was in the range of 1.43-10.84 mg/m3. Based on the chlorophyll-a content, the Kabori Lagoon is included in the mesotrophic category. Spatially, the distribution of chlorophyll-a content varies, but tends to be higher in the southern part of the lagoon than in the northern part of the lagoon.

Abstract:
In aquaculture, fish health problems are often encountered which can lead to failure in cultivation activities. One of the efforts to overcome the problem of disease in cultivation is done by providing immunostimulants. Sweet potato leaves (Ipomoea batatas) are plants that have a short harvest period, cheap and rich in vitamins and antioxidants so that it can be used as a source of immunstimulants. This research was conducted to determine the effect of adding sweet potato leaves (Ipomea batats) to tilapia (Oreochromis niloticus) feed on total leukocytes, phagocytic activity, hematocrit, and survival rate. The study was conducted by experimental method using a completely randomized design, with 4 treatment doses of sweet potato (Ipomoea batatas) used were 0%, 5%, 10% and 15%, which were formulated in fish feed and each treatment was repeated 3 times.. The results showed that giving 10% of sweet potato (Ipomea batatas) leaves in feed had a significant effect on the non-specific immune system of tilapia, which could increase the highest total leukocyte value by 6600 mm3 but did not have a significant effect on the phagocytosis index. 96.3%, 31% hematocrit with 93% survival.

Abstract:
This study aims to analyze the factors that influence the processing income of Baung fish. Sampling using the census method. The data used are primary and secondary data. Data analysis was performed using multiple linear regression. The coefficient of determination (R2) is 0.90, indicating that the processing income of Baung fish (Y) can be explained by the variables of raw materials (X1), supporting materials (X2), transportation costs (X3), amounting to 90% while the remain 10 % is influenced by other factors that are not included in the equation. The significance value of F is 0,000 indicating that H0 is rejected or H1 is accepted, there are the raw materials variable (X1), supporting materials (X2), transportation costs (X3), which is simultaneously have a significant effect on the variable net income of Baung fish processing (Y). Partially the cost of raw materials has an effect on the income of Baung fish processing, in the other hand the supporting costs and transportation costs partially have no effect on the income of processing Baung fish. The classical assumption test shows that the data is normally distributed, there is no multicollinearity and heteroscedasticity.

Abstract:
This research was carried out with a survey method during August 2019 with the aim of knowing the biodiversity of target fish and their potential in the coral reef ecosystem in the waters of Maitara Island, North Maluku Province by collecting primary and secondary data in the form of coral reef conditions (lifeform), fish conditions (diversity, uniformity and dominance) as well as environmental parameter data in the form of temperature, salinity, current velocity, and brightness. The collection of data on the condition of coral reefs and fish was carried out simultaneously, namely 1 dive at each station. Visual census method is used for reef fish data. The results of visual observation of reef fish in the waters of Maitara Island found that there were 13 familyes included in the major fish group consisting of 7 familyes, 1 family of indicator fish and 5 target fish groups. The reef fish found at the observation location of station 1 consisted of 59.3% major fish groups, 24.2% target fish and 16.5% indicator fish and at station 2 reef fish consisted of 62.1 major fish groups. %, target fish is 23.8% and indicator fish is 4.1%. Overall, the results of the visual observations of reef fish showed that major fish were the most dominant, found as much as 66.7% of the target fish groups were 23.9% and indicator fish groups were 9.4%. The lack of presence of indicator fish groups shows that the fertility of the coral reef ecosystem in the waters of Maitara Island is no longer in good condition, because the indicator fish group is a type of fish that indicates good and bad parameters of coral reef conditions in the waters.

Abstract:
One of the coastal ecosystems that has a high primary productivity, seagrass, makes it a places to find foods (feeding ground), spawn (spawning ground), and shelter for most fish. Whether the structure of fish communities on seagrass beds in the coastal waters of Doreri Bay based on day and night observation times is different from previous studies. This study aims to examine the structure of fish communities on seagrass beds in the coastal waters of Doreri Bay, between the time of observation and compared to previous studies. Data collection takes place during April-May 2019. The method used in this study is a descriptive method, using 1 and 1.5 inch gills net. The results of the study found that seagrass beds in Doreri Bay waters were more than in previous studies, which consisted of 10 species of seagrasses from 2 families (Hydrocharitaceae and Cymodoceaceae). The composition of fish is 56 species with a total of 91 individuals during the day and 189 individuals at night. Fish community structure in Doreri Bay waters has moderate diversity and uniformity while low dominance. Efforts should be made to protect seagrass ecosystems so that fish resources in the Doreri Bay region are maintained.

Abstract:
The purpose of this study was to analyze the composition of nutrients contained in kopyok moss and analyze the effect of natural or artificial feed on the growth of tilapia (Oreochromis niloticus). This research was carried out in October-November 2019, met in the UNPUS MSP laboratory and used the experimental method and Completely Randomized Design (CRD). Test animals used were juvenile tilapia 5-7 g; 5-10 cm and totaling 27 individuals. The fish were divided into three treatment groups, namely P1 (PF500 MS PRIMA FEED feed group), P2 (Takari feed group), and P3 (kopyok moss natural feed group) and each group consisted of nine fish. Feeding is done twice a day on an ad libitum basis for 30 days continuously. The results showed that the absolute weight gain in the P2 group was higher than in the P1 and P3 groups, the absolute length increase in P3 was higher than in P1 and P2 and the survival rate of P2 was higher than in P1 and P3. This explains that the nutritional content, especially protein in the feed, must be in the amount needed, otherwise the excess protein will be released into the environment in the form of ammonia (NH3), increased ammonia toxicity can cause damage to the gills and kidneys, decreased growth, disruption of the brain system, and dissolved oxygen levels become low. Based on the results of the study it can be concluded that protein is one of the essential nutrients for growth for survival, but it must be at the amount needed by the body so that it is not released to the environment which will reduce water quality.

Abstract:
This study aims to examine the pattern of mast cell distribution in the intestinal tract of skipjack fish (Katsuwono pelamis) infested with endoparasitic worms and prove the correlation between endoparasitic worms and mast cells which are always involved in hypersensitivity responses. The study was conducted in May to July 2018 at the Paotere Fish Auction Place and at the Animal Climatology Histology Laboratory of Hasanuddin University. A total of 30 skipjack fish originating from the Paotere TPI were used as research samples, the fish were then dissected to be taken inside the organs infested with endoparasitic worms and then fixed and made histopatalogis slide preparations with microtechnic procedures and hematoxylin-eosin staining to be observed under a microscope. The results showed that infestation of endoparasitic worms in the body of skipjack fish could grasp the active mast cells. Mast cells are distributed only to the gonads, gills and heart of skipjack fish (Katsuwonus pelamis).

Abstract:
The Whale Shark (Rinchodon typus) is a species of pelagic fish with the largest size in the world and has a very wide range of movements. By understanding the migration of whale sharks a number of important policies can be immediately applied to preserve the population of this species in nature. This paper aims to provide an overview of the concept and application of spatial science and technology to map and model the migration of whale shark species. This paper is the result of a review of various literatures, both scientific journal articles and books related to mapping and modeling of common marine animals and whale sharks in particular. The paper begins with a description of the bioecological aspects and threats to the whale shark population. Furthermore, the concept of mapping and modeling of whale shark migration will be described, covering important factors in mapping and modeling, development of marine geographic information migration model (GIS) and application of whale shark migration modeling. The conclusion from the review is that bioecological characteristics and patterns of whale shark migration cause these species to be vulnerable to various threats from both natural factors and human activities. Migration mapping and modeling is generally based on environmental variation or oceanographic factors and species movement types. Accurate mapping and modeling results will be of great value in planning and policies regarding the management and conservation of whale shark species.

Abstract:
The economic value of the activity of catching eggs in the waters of the Fak Fak Regency of West Papua not only provides income for migrant fishermen from South Sulawesi but also for the people in the Fak Fak Regency who live in coastal areas. This study aims to provide an overview of the economic impact of flying egg fishing and the marketing channels of these flying fish eggs. Data collection was carried out in August and September 2017 in the coastal areas of Fak Fak and the Fak Fak Fishing Base and several other landing areas. Interview and questionnaire techniques used for data collection also used secondary data from various sources and previous research. The data collected was analyzed descriptively and displayed in graphical form and percentage to reveal facts based on field information. The results showed that in 2017 the production of flying fish eggs per ship ranged from 270 - 1,575 kg, with an average value of IDR 307,446,154. The fish egg marketing channel in Fakfak Regency has 3 main actors namely: producers (fishermen), collecting traders (Papalele) and inter-island traders (Makassar, Takalar). The percentage of costs provided by fly fishing include: (1) fuel and oil 28 %, (2) food supply 26 %, (3) coconut leaves (24 %), and (4) fishing permit (22 %). The economic benefits as an added value from the activity of catching flying fish eggs for the Fak Fak coastal community are the opening of other business opportunities such as coconut leaf providers, fuel and food ingredients providers, boarding or lodging owners, and grater eggs.

Abstract:
The purpose of this study was to analyze the regeneration potential of mangroves found on the coast of Payum, Merauke Regency, Papua Province. This research was conducted in August-October 2018. The data collection technique was purposive sampling using Transect Line Plots. The sampling location was chosen based on the representation of the presence of mangroves in three locations, namely zones A, B and C. The results of this study explained that there were three tree-level mangrove species, namely Avicennia alba, Rhizophora apiculata and Sonneratia alba. Type A. alba dominates in zone A with an important value index (INP) of 205.76%, zone B does not have a certain type that dominates, while Rhizophora apiculata dominates in zone C with INP 185.35%. The potential of the three mangrove species in zones A, B and C is good. Aegialitis annulata species are only found in sapling and seedling levels. In zones A and B are classified as new while in zone C is classified as bad. This study concluded that Avicennia alba, Rhizophora apiculata and Sonneratia alba had the potential to regenerate in all three locations (Zones A, B and C) compared to Aegialitis annulata.

Abstract:
Edera District is the one of separated districts of six districts in the Mappi Regency. The increasing of community population has caused an increase activities in resource utilization, especially in the Digoel River area. As a result of excessive utilization activities can potentially cause pollution that threatens the existence and continuity of organisms such as Gastropods. This study aims to determine the community structure of Gastropods in the Digoel River in Edera District, Mappi Regency. The study lasted for 3 months from January to March 2018 by using the survey method and reviewing several variables including: diversity index, uniformity index and dominance index. The results showed that at the 3 observation stations the total sample was 1233 individuals. The highest diversity index value was at station II, namely itlic. and lowest was at station I Ellobium chinense species. Uniformity index shows that the number of uniformity is not evenly distributed in all three stations due to the occurrence of certain types of dominance.

Abstract:
Mangrove ecosystem is inhabited by a variety of biota, one of the fauna inhabitants of the original mangrove area isgastropods. It is the quality of the waters which certainly has a direct impact on aquatic biota. Nitrate and phosphateare needed by gastropods because they are related to nutrient availability. The purpose of this study is to determinethe phosphate and nitrate contents and analyze the relationship between phosphate and nitrate contents and thepresence of gastropods in the mangrove ecosystem at the Kambapi Beach, Merauke. Data analysis used ecologicaldata of abundance, diversity, dominance and PCA. The results showed that phosphate contents ranged from 0.002-0.04 mg / l and nitrate ranged from 0.007 to 0.19 mg / l, whereas in sediment phosphate contents ranged from 9.63-19.32 mg / l and nitrates ranged from 0.89-4.55mg / l. The results of the analysis of the relationship between thepresence of gastropods and phosphate and nitrate indicates that the parameters of phosphate and nitrate in sedimentsand phosphates in waters have a positive value which means that these parameters affect the presence of gastropoddensity while the environment parameters which correlate negatively is nitrate in the water. This shows that thenitrate contents in water have an inverse relationship with gastropod density.Keywords: Gastropod, Merauke, Phosphate, Nitrate

Abstract:
Forests reduce and store CO2 through a process of "sequestration" that is the storage of carbon from the atmosphere and its storage in several copartments such as plants, litter, and soil organic matter. Mangrove forest is a unique and unique type of forest because it is able to adapt to environments with high salinity, soil conditions without oxygen and once in a while. ne example of mangrove forests in Indonesia is mangrove forest in the Kumbe river estuary, Merauke Regency, Papua Province. The Kumbe river estuary is one of the eastern Indonesian waters bordering the Indian Ocean. At the Kumbe river estuary there has been no research on carbon stocks in the mangrove community. So it is necessary to do research on carbon stocks in the region. In this study the measurement of carbon stocks used was done by measuring carbon above ground, and ground. Above ground carbon stock components include trees, understorey, and litter. The mechanism for measuring above ground carbon stock is done by estimating biomass, which is then converted to carbon concentration. The results of this study indicate that the carbon stocks in trees, Understorey and litter in sequence are 85.55 Mg / Ha, 392.93 Mg / Ha and 70.75 Mg / Ha; 0.78 Mg / Ha, 1.26 Mg / Ha and 1.24 Mg / Ha and 2.04 Mg / Ha, 1.28 Mg / Ha and 1.2 Mg / Ha. As for the proportion of carbon stock values ​​found in mangrove forests that trees contribute greatly to total carbon stock. Keyword : Mangrove, carbon stocks, Merauke, Kumbe
