Penelitian ini bertujuan untuk mengetahui padat tebar optimal terhadap pertumbuhan ikan sidat dengan sistem air mengalir pada fase pembesaran. Ikan uji yang digunakan yaitu ikan sidat (Anguilla bicolor) dengan bobot ±59 g dan keseragaman ukuran ±80% yang diperoleh dari hasil tangkapan alam di daerah Cilacap. Metode uji yang digunakan adalah eksperimental skala lapang dengan padat tebar yang digunakan yaitu B1 (3,41 g L-1 atau 34 ekor m-2) dan B2 (3,62 g L-1 atau 36 ekor m-2). Pemeliharaan dilakukan selama enam bulan pada bak fiber persegi panjang berukuran 5,8 m × 0,85 m × 1,12 m. Respon yang diamati meliputi laju pertumbuhan spesifik (LPS), tingkat kelangsungan hidup (TKH) dan rasio konversi pakan (RKP). Hasil penelitian menunjukkan bahwa perlakuan B2 (3,62 g L-1) menghasilkan nilai LPS dan RKP yang lebih baik dibandingkan perlakuan B1 (3,41 g L-1), dimana nilai LPS dan RKP yang diperoleh yaitu sebesar 0,42% hari-1 dan 4,64. Perbedaan padat tebar tidak memberikan pengaruh terhadap TKH ikan sidat, dimana nilai TKH untuk semua perlakuan mencapai 100%.This study aims to determine the optimal stocking densities of eel (Anguilla bicolor) with a running water system in the grower stage. The test fish used were eels with a weight of ±59 g and size homogeneity of ±80% obtained from natural catches in the Cilacap area. The test method used was field-scale experimental with stocking densities used as B1 (3,41 g L-1 or 34 fish m-2) and B2 (3,62 g L-1 or 36 fish m-2). The rearing was conducted for six months in rectangular fiber tanks measuring 5,8 m × 0,85 m × 1,12 m. Responses observed included specific growth rate, survival rate, and feed conversion ratio. The results showed that treatment B2 (3,62 g L-1) with higher stocking density produced higher SGR and FCR than treatment B1 (3,41 g L-1) at 0,42% day-1; 4,64 and 0,37% day-1; 5,84, respectively. Differences in stocking density in this study are also known to have no effect on eel survival, in which SR values during the rearing of all treatments reached 100%.

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

The main issue addressed in this study is the application of intensive whiteleg shrimp (Litopenaeus vannamei) culture at PT Padak Goar, East Lombok Regency, Indonesia. The objective of this study is to determine the technical parameters of intensive Vannamei shrimp farming, including stocking density, feed management, growth performance (ABW and ADG), feed efficiency (FCR), survival rate (SR), and their relationship with water quality.. The study was conducted in two grow-out ponds with surface areas of 7,648 m2 (B4) and 7,680 m2 (B5). Data collection covered stocking density, Average Body Weight (ABW), Feed Conversion Ratio (FCR), and Survival Rate (SR). The observation results were then analyzed using a quantitative descriptive approach to assess feed consumption in relation to production parameters, particularly FCR and shrimp growth. The results showed that in pond B4, the stocking density was 124 ind/m2, ABW was 14.3 g, ADG ranged from 0.24 to 0.37 g/day, FCR was 1.7, and SR was 70%, while in pond B5, the stocking density was 125 ind/m2, ABW was 12.9 g, ADG ranged from 0.21 to 0.33 g/day, FCR was 1.9, and SR was 66%. The results indicate that the intensive culture system is capable of supporting good shrimp growth and survival; however, differences in feed efficiency between ponds suggest that water quality and feed management play important roles in determining production performance. Permasalahan dalam penelitian ini adalah bagaimana penerapan sistem budidaya udang Vannamei (Litopenaeus vannamei) secara intensif di PT Padak Goar Kabupaten Lombok Timur. Tujuan penelitian ini adalah untuk mengetahui parameter teknis budidaya intensif udang Vannamei meliputi meliputi padat tebar, manajemen pakan, pertumbuhan (ABW dan ADG), efisiensi pakan (FCR), tingkat kelangsungan hidup (SR), serta keterkaitannya dengan kualitas air. Penelitian dilakukan dengan metode observasi lapangan pada dua petak tambak dengan luas masing-masing 7.648 m2 (B4) dan 7.680 m2 (B5). Data yang diamati mencakup padat tebar benur, Average Body Weight (ABW), Feed Conversion Ratio (FCR), serta Survival Rate (SR). Hasil pengamatan kemudian dianalisis secara deskriptif kuantitatif untuk konsumsi pakan terhadap parameter produksi, khususnya FCR dan pertumbuhan udang. Terjemhkan ke bahasa Inggris yang baik dan benar. Hasil penelitian menunjukkan bahwa pada petak B4 diperoleh padat tebar 124 ekor/m2, ABW 14,3 g, ADG 0,24–0,37 g/hari, FCR 1,7, dan SR 70%, sedangkan pada petak B5 diperoleh padat tebar 125 ekor/m2, ABW 12,9 g, ADG 0,21–0,33 g/hari, FCR 1,9, dan SR 66%. Hasil penelitian menunjukkan bahwa sistem budidaya intensif mampu mendukung pertumbuhan dan kelangsungan hidup udang yang baik; namun, perbedaan efisiensi pakan antar petak mengindikasikan bahwa kualitas air dan manajemen pakan berperan penting dalam menentukan kinerja produksi.
