Tujuan dari penelitian ini adalah untuk menganalisis perbedaan padat penebaran terhadap pertumbuhan dan kelangsungan hidup udang vaname. Penelitian ini dilakukan selama DOC 80 dengan kepadatan X1 200 ekor/m2, X2 300 ekor/m2 dan X3 150 ekor/m2. Pengambilan data pertumbuhan dilakukan setiap 10 hari sekali. Metode analisis data yang digunakan adalah deskriptif kuantitatif. Hasil penelitian pada perlakuan X1, X2, X3 rata-rata mengalami peningkatan pertumbuhan bobot dari DOC 30 sampai DOC 80. X1 menunjukan laju pertumbuhan lebih tinggi dibandingkan dengan X2 dan X3. Begitu juga, tingkat kelangsungn hidup udang pada X1 lebih tinggi dibandingkan X2 dan X3. Hal ini diduga jumlah populasi dapat mempengarui pertumbuhan dan kelangsungan hidup udang. Oleh karena itu dalam budidaya perlu adanya pertimbangan dan perhitungan yang matang dalam menentukan jumlah padat tebar. The purpose of this study was to analyze the differences in stocking density on the growth and survivel rate of whiteleg shrimp. This research was conducted during DOC 80 with a density of X1 200 individuals/m2, X2 300 individuals/m2, and X3 150 individuals/m2. Growth data collection is carried out every 10 days. The data analysis method used is descriptive quantitative. The results of the research on treatment X1, X2, X3 experienced an increase in weight growth from DOC 30 to DOC 80. X1 showed a higher growth rate compared to X2 and X3. Similary, the survival rate of shrimp at X1 was higher than in X2 and X3. It is assumed that the population number can affect the growth and survival of shrimp. Therefore, in shrimp farming, it is necessary to have careful consideration and calculation in determining the amount of stocking density.

Stocking density plays a very important role in the process of Whiteleg shrimp seeding. High stocking density in Whiteleg shrimp larvae will affect the growth and survival of the shrimp. This study aims to analyze the growth and survival of whiteleg shrimp larvae with different stocking densities. The research method used is experimental. This study consists of 1 stocking density treatment with a stocking density of 115 fish/L (treatment A) and 176 fish/L treatment (D) which is repeated 3 times. This study consists of 6 tanks with a volume of 13,000 liters. During the maintenance period, the larvae were given natural feed and artificial feed. The parameters tested were water quality (temperature, pH, DO and salinity), survival and growth parameters. Data analysis used ANOVA. The results of the study showed that the population in the form of a presentation of each larval stage of treatment A was significantly different from treatment D. Likewise, the results of the survival analysis of treatment A were significantly different from treatment B. This means that treatment A with a density of 115 fish/L had better survival compared to a density of 176 fish/L. However, the results of the analysis in treatment A were not significantly different from treatment D. This means that the stocking density does not affect the growth of post larvae. The recommendation for proper stocking density in larval maintenance to produce high survival is to use a stocking density of 115 fish/L

Mangrove crabs are one of the important fisheries commodities in Indonesia which have made a significant contribution to the lives of coastal communities. This study aims to analyze differences in growth performance of mud crabs reared in different silvofishery ponds to find out the effect of gender and to determine the interaction patterns between silvofishery pond type and gender. This research method uses a Factorial Randomized Block Design (FRBD) which consists of two factors, namely pond type (core pond, trench pond) and sex (male, female) so that it has 6 treatment combinations and 3 replications for each treatment. The initial weight of the test mud crab was 70-75 g. Test animals were kept for 56 days in crab baskets. The results showed that the interaction between pond type and sex had a significant influence on daily growth rate and absolute weight growth but did not significantly influence the feed conversion ratio and feed utilization efficiency. Duncan's further tests showed that the type of pond had a real influence on the feed conversion ratio and feed utilization efficiency. The best Feed Conversion Ratio was found in the core pond treatment with 3.80 1.05 with the highest feed utilization efficiency of 27.67 3.23 %.The survival rate shows values that are not significantly different between all treatments (86.67 100%.). The water quality measurement values during the research were still optimal for the growth of male and female mud crabs. Treatment of core ponds with female crabs (T2K2) showed the best performance in terms of daily growth rate and absolute weight growth of mud crabs. Core pond treatment with female crabs showed the highest daily growth results of 0.82% 0.01% and absolute growth of 42.00 1.00.Keywords:Mud crabSilvofisheryCore PondDitch PondGenderGrowth

Udang vaname (Litopenaeus vannamei) merupakan salah satu komoditas perikanan budidaya yang dapat memenuhi kebutuhan protein hewani bagi masyarakat. Sistem pemeliharaan udang vaname dapat dilakukan secara tradisional dan intensif. Tantangan terbesar kegiatan budidaya udang saat ini adalah penyakit yang dapat menimbulkan kerugian bagi pembudidaya. Serangan penyakit yang disebabkan oleh parasit terutama jenis protozoa yang sering menyerang udang vaname adalah Zoothamnium sp., Vorticella sp. dan Epistylis sp. yang menyebabkan penyakit Enterocytozoon hepatopenaei atau EHP. Penelitian ini bertujuan untuk mengetahui perbandingan jenis parasit, prevalensi, intensitas serangan parasit dan kualitas air pada udang vanname di tambak intensif dan tradisional. Metode penelitian yang digunakan adalah metode deskriptif dengan metode pengambilan sampel secara purposive random sampling. Sampel yang diambil pada saat berumur atau DOC 35 – 90 hari dengan berat rata-rata per ekor atau ABW 1 sampai 10.0gr/ekor. Pemeriksaan ektoparasit dilakukan pada kaki jalan, kaki renang, insang, dan lendir. Parameter yang diamati meliputi prevalensi dan intensitas penyakit, kualitas air seperti alkalinitas, total organic matter (TOM), Nitrit (NO₂) dan amoniak (NH₄). Hasil pengamatan parasit pada udang vaname yang dipelihara di tambak intensif dan tradisional terdapat tiga spesies teridentifikasi yang menginfeksi yaitu Epistylis sp., Vorticella sp., dan Zoothamnium sp. dengan prevalensi pada tambak intensif lebih tinggi dibandingkan dengan prevalensi pada tambak tradisional yakni sebesar 95,56% dan 56,6%, begitupula dengan hasil perhitungan intensitas menunjukkan persentasi intensitas pada tambak intensif lebih tinggi dibandingkan tambak tradisional dengan nilai masing-masing sebesar 4,3 dan 2,46 ind/ekor. Kualitas air seperti alkalinitas, NO₂, NH₄, dan TOM pada tambak intensif memiliki nilai yang lebih tinggi dibandingkan dengan tambak tradisional.

Laut Arafura di Wilayah Pengelolaan Perikanan Negara Republik Indonesia (WPP-NRI) 718 merupakan salah satu daerah penangkapan ikan pelagis yang penting karena memiliki potensi sumber daya ikan yang melimpah. Salah satu teknik yang digunakan untuk meningkatkan hasil tangkapan dengan alat tangkap purse seine adalah pencahayaan buatan. Penelitian ini bertujuan untuk membandingkan pengaruh dua durasi penyinaran cahaya, yaitu 500 menit dan 600 menit, terhadap hasil tangkapan ikan. Penelitian dilakukan selama tiga bulan (Desember 2023 – Februari 2024) di atas kapal KMN. Agung Sobrah yang beroperasi di WPP 718. Metode yang digunakan adalah eksperimen lapangan dengan masing-masing perlakuan diulang enam kali. Data dianalisis menggunakan uji-t dua sampel independen (α = 0,05) dan analisis deskriptif untuk komposisi jenis ikan. Hasil menunjukkan bahwa tidak ada perbedaan signifikan jumlah hasil tangkapan antara dua durasi penyinaran (P0,143<0.05). Namun, terdapat variasi jenis ikan yang tertangkap tiap bulan. Dengan demikian, durasi penyinaran 500–600 menit tidak memengaruhi jumlah tangkapan secara nyata, tetapi berpengaruh terhadap komposisi spesies. Penelitian lanjutan perlu mempertimbangkan faktor lingkungan perairan.The Arafura Sea, located within Indonesia’s Fisheries Management Area of the Republic of Indonesia (WPPNRI) 718, is one of the key fishing grounds for pelagic fish species because it has abundant fish resource potential. One method used to enhance the effectiveness of purse seine fishing in this area is the application of artificial lighting. This study aimed to compare the effect of two different lighting durations—500 minutes and 600 minutes—on fish catch performance. The research was conducted over three months (December 2023– February 2024) aboard the KMN Agung Sobrah, operating in WPP 718. A field experiment approach was used, with each treatment replicated six times. Data were analyzed using an independent two-sample t-test (α = 0.05) and descriptive analysis to assess species composition. The results showed no significant difference in total catch between the two lighting durations (P = 0.143). However, variations in species composition were observed across months. Thus, while lighting duration between 500 and 600 minutes did not significantly affect total catch volume, it influenced the types of species caught. Further research should consider oceanographic and behavioral factors to better understand these outcomes.

Plankton merupakan salah satu jenis pakan alami yang berperan penting untuk pertumbuhan organisme akuatik terutama ikan. Tujuan dari penelitian ini adalah untuk mengetahui jenis-jenis plankton beserta kelimpahannya di perairan dan di lambung ikan nila yang tertangkap di Waduk Wonorejo, beserta aktivitas enzimatis lambung ikan nila tersebut. Penelitian ini bertempat di Waduk Wonorejo, Tulungagung, Jawa Timur dengan metode survei. Sampel diambil dari 2 stasiun, yaitu stasiun pertama di daerah wisata Waduk Wonorejo, sedangkan stasiun 2 berada di wilayah pemancingan umum Waduk Wonorejo. Plankton di perairan Waduk Wonorejo ditemukan 17 genus fitoplankton, dan 5 genus zooplankton, sedangkan di lambung ikan nila ditemukan 30 genus fitoplankton dan 2 genus zooplankton. Genus Spirogyra sp. merupakan genus yang paling tinggi kehadirannya baik di lambung maupun perairan Waduk Wonorejo. Kelimpahan plankton di perairan waduk dapat digolongkan oligotrofik dengan nilai kelimpahan plankton sebesar 1487 ind/ml di stasiun 1 dengan keanekaragaman tinggi dan 746 ind/ml di stasiun 2 dengan keanekaragaman sedang, serta tidak ada jenis plankton tertentu yang mendominasi di kedua stasiun tersebut. Analisis aktivitas enzim lambung ikan nila menunjukkan aktivitas enzim protease sebesar 0,84 Â± 0,02 Âµmol tirosin/g enzim menit; enzim amilase 14,59 Â± 1,07 Âµmol glukosa/g enzim menit; enzim lipase 17,83 Â± 0,14 Âµmol asam lemak/g enzim menit. Kualitas air di Waduk Wonorejo tergolong baik dengan suhu berkisar 26,3-27,3 oC, pH 7, DO 7,1-8,4 mg/L, Kecerahan 110-154 cm, TOM 19-30,3 mg/L. Maka dari itu upaya untuk mempertahankan kondisi Waduk Wonorejo agar tetap oligotrofik perlu dilakukan.
