The practical application of waste recycling as feed supplement is potentially required by small-scale aquaculturist. Furthermore, some of the flour derived from waste sea urchin shells and in adopted in feed, including Deadema setosum were evaluated to estimate the effect on white shrimp Litopenaeus vannamei moulting. This research required the experimentation of four doses with triplicate supplementation (0, 2, 4, and 6 g 100 g-1 of feed) on shrimps four times daily (12% of body weight) for 35 days test period. The juvenile specimens, characterized by an initial weight of 1.61±0.11 g, were stocked at a density of 12 individuals in a 12 L aquarium. In addition, four compartments were created in each aquarium to facilitate progress observations. The proximate analysis results showed a 53.76±0.27% calcium content in the shell flour, which significantly increased (P0.05) after higher dose supplementation, in the sequential order 18.65±0.13%, 20.04±0.08%, 23.18±0.10%, and 25.04±0.11%. Moreover, the frequency and moulting interval with 4 g doses (16.59%±0.36% day-1 and 5.91±0.18 days-1) were significant (P0.05) and considered the best, compared to 0 g (10.48% ± 0.24% day-1 and 9.97±0.37 days-1), 2 g (13.49%±0.96% day-1 and 8.10±0.29 days-1), and 6 g (13.81%±0.24% day-1 and 7.90±0.06 days-1). In addition, the respective trend pattern for both parameters increased and decreased at 4 g and 6 g, correspondingly. The highest moulting intensity was also obtained with the 4 g doses, at a range of 4 to 6 times, while the lowest (0 g) varied from 3 to 4 times. These sea urchin shell flour was determined to have numerous practical applications as a feed supplement with proven ability to stimulate moulting in vannamei shrimp.Keywords:MoultingCalciumShellSea urchinFeed supplementationVannamei shrimp

Many aquaculture wastes are suspended in the water column in that the presence of clams as filter feeders is required to utilize the waste for growth. In this study, blood clams from four aquaculture systems were evaluated to determine their growth, namely monoculture systems, polycultures, Integrated Multi Trophic Aquaculture (IMTA) non-paddy cocultures, and IMTA with paddy cocultures. Blood clams, tilapia, and tiger shrimp are stocked at as much as 20 each in 90 L of brackish water, whereas the density of sea cucumbers is 10 individuals. For paddy, reared using a floating method that uses trays. For four weeks, feed was given four times a day as much as 10% of the biomass. The results showed that the aquaculture system were a significant effect (P<0.05) on Spesific Growth Rate (SGR). The SGR of blood clams when combined with the IMTA systems were significantly higher (P<0.05) than that of the monoculture and polyculture systems. In contrast to growth, morphometric characteristics were not significantly affected (P>0.05) by aquaculture system. Apart from studies in laboratory scale, the highest growth of blood clams is obtained if cultured with complete trophic levels through the IMTA paddy system.

Amonia (NH3-N) adalah nitrogen terlarut yang paling berbahaya dari limbah akuakultur. Sebuah eksperimen telah dilakukan untuk mengevaluasi sistem kokultur yang efisien dalam mereduksi NH3-N. Sebanyak 4 spesies hewan akuaktik, yaitu ikan nila (Oreochromis niloticus), udang windu (Penaeus monodon), kerang darah (Tegillarca granosa), dan teripang pasir (Holothuria scabra), serta tanaman padi (Oryza sativa) dikombinasikan pada beberapa sistem akuakultur. Enam perlakuan dan masing-masing dengan tiga ulangan dirancang menggunakan rancangan acak lengkap (RAL). Benih hewan akuatik diaklimatisasi secara bertahap selama 30 hari. Benih padi disemai di air payau, selanjutnya ditebar menggunakan metode apung. Selama 28 hari eksperimen, ikan nila dan udang windu diberi pakan 4 kali sehari dengan feeding rate sebesar 10% bobot biomas, sedangkan kerang darah dan teripang pasar tidak diberikan pakan. Hasil menunjukkan bahwa efisiensi reduksi nutrien (ERN) NH3-N di dua sistem monokultur bernilai negatif, sementara empat sistem kokultur bernilai positif. Nilai ERN dua perlakuan sistem polikultur tidak berbeda (P>0,05). Sementara itu, nilai ERN pada sistem IMTA lebih tinggi dari sistem monokultur maupun polikultur (P<0,05). Temuan ini mengarah pada pemanfaatan keanekaragaman spesies untuk akuakultur berkelanjutan di air payau. Hal ini dapat disimpulkan bahwa sistem akuakultur yang paling efisien dalam mereduksi NH3-N adalah sistem IMTA-padi dengan nilai ERN sebesar 43,3±1,7%. Nilai ini lebih tinggi (P<0,05) dari semua sistem akuakultur lainnya
