Abstract:
Culture of molluscan is clearly limited by the availability of seed, as this production proceeds almost exclusively from natural recruitment. Artificial spawning and larval rearing programs could provide an alternative source of spat. This
study
was designed to evaluate the effect of different conditioning temperature and salinity on the broodstock maturation and Condition Factor of mangrove clam (P. erosa) collected from different locations of Ratnagiri coast. Batches of clams from different sites were collected in February, and conditioned at temperature 26 °C, 28 °C, 30 °C and 32 °C. For conditioning at different salinity, it was kept at 10,15,20,25,30 and 35 psu, The results showed that the oocyte maturation was faster at salinity 35 psu and the best conditioning temperature was 32 °C. The Condition Factor (CF) was higher at 32 °C temperature and at 30 psu salinity, whereas, no significant difference was observed in CF at 30 and 35 psu. These results suggest that the efficient conditioning temperature and salinity is related to the natural spawning season.

Abstract:
The present
study
is the first attempt to
study
the taxonomy and diversity of molluscan fauna from freshwater bodies of Chandigarh (U.T.) and Ghaggar River flowing on its southeast border. A total of 24 molluscan species (17 gastropods, 3 bivalves and 4 land snails) were collected from the selected sites. Physa acuta was found showing ubiquitous occurrence along with its maximum abundance in all water bodies followed by Melanoides tuberculata. Less biodiversity and the presence of tolerant species indicated that majority of the water bodies under
study
are under a great threat of degradation. The results of this
study
will contribute to the knowledge of the regional malacofauna along with identification of the sites facing natural and human interferences.

Abstract:
Fish distribution and consumption trends are varied among the people in Sri Lanka. A market and consumer
study
was conducted to identify the distribution of different fish species in the markets of the district. Moreover a pre-tested questionnaire was employed to collect information on fish consumption behavior and social and cultural factors influencing on fish consumption. Following the purposive sampling technique information were collected from 200 people who came to purchase fish from fish outlets. Results showed that 85% of the respondents consume fish as their major protein food and 25% people consumed fish for health purpose. However, all respondents mentioned that fish availability and distribution was the major constraints for consumption of their preferred type of fish. Among the respondents in urban area, approximately 45% of the respondents preferred seashore fishes (family: clupidae) and 40% preferred reef fishes (family:carangidae) and 15% consume fresh water fishes (family:cichlidae), but consumption depends on the availability of fish in the respective area and socio economical factors. Distribution of fish in markets showed variation in rural and urban markets. In this line, Shore fish and rock fishes have been distributed in 75% of the outlets in urban markets and 25% outlets had the brackish and fresh water fishes while in rural markets distribution of seafishes as 25% and 75% was brackish and fresh water fishes.

Abstract:
Fishery
development is considered as a potential area to enhance income of smallholder farmers in developing countries. In Ethiopia fishing practiced in most freshwater bodies which is a potential strategy for enhancing food security, employment and provide as source of income. Despite the economic importance of fishing at the local level, farm households have paid little attention to the fish production in the
study
area. Thus, this
study
was proposed to analyze determinants of farmer’s participation decision on fishing in Langano Lake. The
study
used the cross-sectional survey to collect primary data from 167 same respondents and mixed research approach. Descriptive statistics, inferential statistics and binary probit model were used to analyze the primary data. The result of analysis indicated that farmer`s’ participation in fish production is significantly determined by various demographic, institutional, social, economic and biophysical factors. To solve the problems and improve the farmer`s participation in fish production,the government and nongovernment organizations, specially district livestock and
fishery
development office should attempt to hamper factors that hind er participation in fish production and enhance factors that initiates participation in the fishing practice identified in the
study

Abstract:
This
study
aims to find the concentration of pandanus (Pandanus amaryllifolius) leaves extract that can inhibit the growth of Aeromonas hydrophllia (in vitro test) and LC50-24 hour pandan leaves extract against sangkuriang catfish fry (in vivo test). The research method used was experimental with a completely randomized design (CRD), using five treatments and three replications for the in vitro test, while for the in vivo test six treatments and two replications. The treatment for the in vitro test was pandanus leaves extract with a concentration of A. 600 ppm, B 800 ppm, C 1000 ppm and D 1200 ppm. While the treatment for the in vivo test was A. 0 ppm, B. 10 ppm, C. 100 ppm, D. 500 ppm, E.1000 ppm and F. 3000 ppm. A. hydrophilla bacteria used with a density of 108 CFU / mL Sangkuriang catfish used for the in vivo test measuring 5-7 cm. The parameters observed were the diameter of the inhibition zone and fish mortality (LC50-24 hours). Inhibition zone data were analyzed using the F test, and the 24-hour LC50 test dat1. a were analyzed descriptively. The results showed that pandanus leaves extract at a concentration of 1200 ppm was able to inhibit the growth of A. hydrophila bacteria in the strong category with an average inhibition zone diameter of 14.30 mm and an LC50-24 hour value obtained at a concentration of 1737.714 ppm. The conclusion of this
study
is that pandanus leaves extract can be used to treat catfish that are attacked by A. hydrophila with a concentration below 1737,714 ppm.

Abstract:
The structure and distribution of the fish population were investigated from March 2019 to February 2020 in relation to environmental variables in the Bandama River estuary. Overall, the estuary showed environmental homogeneity outside of the conductivity and width of the
study
area. A total of 52 species of fish were recorded, belonging to 48 genera, 28 families and 12 orders. This ichthyofauna was composed of 24 native freshwater species, 27 brackish and marine species and a hybrid (Coptodon guineensis x Coptodon zillii). The species defined a distribution according to their ecological category in the Bandama estuary. Redundancy analysis (ARD) indicated that salinity and bed width are the main variables that influence the fish species distribution in the Bandama River estuary.

Abstract:
Arcachon Bay, in the southern Bay of Biscay, is the first French production area of Manila clam (Ruditapes philippinarum) with an annual commercial
fisheries
production around 400 tons in recent years. This bivalve mollusc was introduced into the bay in the 1980s for aquaculture purpose and quickly succeeded in natural settlement so that its high market value led to the progressive establishment of a perennial
fishery
from the mid-1990s. Local management plans applied to this species are based on a licensing system for the commercial, protected
fishery
areas and days of prohibited fishing for both commercial and recreational fishermen. A minimum catch size is also prescribed by European regulation, and so growth rates are an important matter in this context. This work focuses on
studying
shell growth from the recapture of shells, previously marked using a chemical marker (calcein) and then grown in natural conditions, and was performed in order to determine shell growth patterns. Manila clams were marked by immersion in situ in seawater containing calcein. In order to
study
the limitations of calcein on the mark readability in situ and manila clam mortality, various exposure times, from 30 minutes to 1 hour, and concentrations, from 50 mg.L-1 to 200 mg.L-1 were tested. After a period of 35 days, 69 growth micro-increments were observed, and, it was found that increment deposition in manila clams occurs with a tidal periodicity. Moreover, this
study
showed that a method for fast-marking of manila clams, and potentially other species, is feasible in situ.
