Abstract:
Microorganisms that often contaminate fishery products were from bacteria groups. Some spesies of bacteria were harmful to human health because they can cause disease and even death in humans, such as Escherichia coli and Salmonella. Therefore its were needed for quarantine and microbiological examination of fishery products as an effort to prevent the spread of disease in humans. The aims of this study were to identify the contamination of E. coli and Salmonella bacteria in fishery products. A total eight samples of fishery products tested consist of canned dan frozen products using conventional methods based on ISO 16649-3: 2015 for E. coli and ISO 01-2332.2-2006 for Salmonella. The results showed that one from the six fishery products tested were frozen boiled tuna that positively E. coli and no fishery product sample was identified with Salmonella.

Abstract:
A single specimen of saltwater crocodile Crocodylus porosus Schneider, 1801 (1.50 cm in length) was captured and photographed by a local fisherman by gill net at fishpond around mangrove ecosystem of east coast Surabaya on December 2020. The location where the estuarine crocodile caught is an important wetland area in Surabaya with an excellent mangrove cover. Wonorejo mangrove location is about 10 km from the centre of Surabaya, the second-largest city in Indonesia. This finding is considered as a first reported of C. porosus in Surabaya, and at the same time is proof of the importance of the mangrove area on the east coast of Surabaya as a habitat for wildlife that must be conserved appropriately. Routine monitoring of mangrove areas, including their wildlife, is essential so that they are not displaced by the development of the city which changes the land function to become a residential area.

Abstract:
Daun pepaya merupakan bahan alami yang sering dimanfaatkan dibidang perikanan air tawar khususnya sebagai pakan tambahan, karena memiliki kandungan enzim yang dibutuhkan oleh ikan. Penelitian inibertujuanuntuk menganalisis pengaruh penambahan serbuk daun pepaya pada pakan untuk meningkatkan pertumbuhan ikan lele (Clarias sp). Pakan yang digunakan pada penelitian ini yaitu pakan komersil dengan kandungan protein 30% yang ditambahkan serbuk daun pepaya. Serbuk daun pepaya didapatkan dari daun pepaya yang dikeringkan terlebih dahulu sampai benar-benar kering. Setelah kering daun pepaya dihaluskan dengan menggunakan blender. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL), dengan 4 perlakuan dan 3 ulangan. Perlakuan 1 (P1) sebagai kontrol (tanpa pemberian serbuk daun pepaya), P2 (pakan dengan serbuk daun pepaya 2 %), P3 (Pakan dengan serbuk daun pepaya 3,5 %), P4 (pakan dengan serbuk daun pepaya 4,2 %). Parameter pertumbuhan merupakan parameter utama yang diamati pada penelitian ini. Analisis data menggunakan ANOVA untuk meliihat perbedaan pengaruh dari masing masing perlakuan dengan selang kepercayaan 95% (p>0.05). Hasil penelitian menunjukan bahwa penambahan serbuk daun pepaya memberikan pengaruh nyata terhadap laju pertumbuhan panjang dan berat (p>0.05), dimana perlakuan terbaik terdapat pada P3 dengan pertumbuahan panjang sebesar 2,69 g dan 3,51 cm, berat dan panjang spesifik 3,89 g dan 5,89 cm, serta FCR 0,517.

Abstract:
Utilisation of plant proteins to replace fish meal in shrimp feeds has become an important consideration because fish meal is becoming more expensive due to increasing demand worldwide. The potential use of palm kernel meal (PKM) in this study to substitute fish meal in the Pacific white shrimp (Litopenaeus vannamei) diets was evaluated by conducting a 90-day feeding trial. Shrimp juveniles with an initial average weight of 0.5 g, protein content of 10.74±0.70% were randomly distributed into five treatments in triplicates. Four isonitrogenous (approximately 35% protein) diets were formulated to contain 0% (D0), 25% (D25), 50% (D50) and 75% (D75) of PKM replacement and a commercial feed served as control treatment (Control). Results from this study revealed that shrimps fed D25 were comparable with those fed with Control as there was no significant difference (p>0.05) in weight gain and specific growth rate (SGR) between the groups. However, PKM inclusions above 50% showed detrimental effects on the growth performance. The highest total protein percent was observed in shrimp tissues fed with D25 (67.59±0.87%) and D75 showed the lowest protein among the treatments (57.4±0.63%) (p<0.05). Total lipid content was observed high in shrimps fed with Control (4.33±2.96%) and decreased with PKM replacement levels. The highest carbohydrate was found in shrimps fed with D75 (16.75±0.04%) and the lowest was found in shrimps fed with D25 (14.67±0.07%). When PKM is utilised to replace FM, a limit of 25% level should be recommended.

Abstract:
Shrimp aquaculture wastewater after the end of the rearing period has a high total organic matter (TOM) content of up to 87.74 mg/L. If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter. The aim of this study was to determine the rate of reduce of organic matter in pond aquaculture waste. The study was carried out in January 2021. Pond wastewater samples were taken from the Tambak at the end of the maintenance period (120 days of maintenance). The trademarks of the bacterial consortium are EM4, Bio HS, BIO Prisma, Starbio plus, BIO2000, and Biolet. The experimental research was arranged in a completely randomized design with 6 treatments and 4 replications. Each treatment was filled with 2 liters of wastewater plus 6 ml of a liquid bacterial consortium. As for the solid bacterial consortium, 1 gram/L was added. Measurements of total organic matter, temperature, pH, dissolved oxygen, salinity and carbon dioxide were carried out every 24 hours for 72 hours of observation. The results showed that during 72 hours of immersion the highest percent reduction in organic matter was in treatment E (BIO 2000) of 95% (87.74 mg/L to 4.11 mg/L). The lowest percentage decrease was in treatment D (Starbio plus) of 83.4% (87.74 mg/L to 14.54 mg/L). However, in general 6 types of bacterial consortium trademarks can degrade organic matter. The levels of temperature, pH, dissolved oxygen and salinity are in optimum conditions, while carbon dioxide exceeds the threshold caused by the high activity of overhauling organic matter by bacteria. The conclusion was obtained that the trademark of the bacterial consortium BIO2000 was the most effective in reducing organic matter for 72 hours.Keyword : Shirmp wastewater, Tambak, Bioremediation, Organic Matter, Microorganis
