“…The price reported by Dennis et al 7 (USD 0.51-0.64 per kg) suggests a further doubling of 'trash' fish price in the subsequent 8 years to 2018. Mak et al 127 also noted steadily rising prices for 'trash' fish in Cambodia.…”

“…It is therefore important to define nutritional requirements across the commercial size range for a given species; in Vietnam, for example, TGGG hybrid are sold when they reach a market size of 0.8-2 kg. 7 Conversion efficiency of feed to fish growth declines as fish grow, 14,131 meaning that an increasing volume of feed is required per unit growth as fish increase in size. Commercial FCR values have been reported at 1.3-1.5:1 for formulated grouper feed in Vietnam 7…”

“…Grouper aquaculture in South-East Asia currently relies heavily on wild-caught fish as feed, especially for larger fish. 1,6,7 Such wild fish is typically termed 'trash' fish. While this term is somewhat derogatory, implying lesser importance, we use it for consistent understanding of the use of wild-caught low-value feed fish rather than any implication that it is of little value.…”

“…5 Feeds have been estimated to make up between 40% and 60% of production costs for grouper in Asia 6 and between 44% and 86% for hybrid grouper specifically. 7 Clearly, improving the cost-effectiveness of compounded feeds for grouper farming will improve overall farm profitability.…”

Groupers, encompassing species in the subfamily Epinephelinae, family Serranidae, are of particular economic importance in Asian aquaculture. 1 The grouper aquaculture industry has experienced a recent trend towards increased production of hybrids, due to the improved growth and disease resistance of the hybrid compared with the parent species. 1,2 The predominantly farmed hybrid is between tiger grouper (Epinephelus fuscoguttatus) females and giant grouper (Epinephelus lanceolatus) males, which we

“…Benih yang lebih kecil umumnya belum siap untuk dipelihara pada karamba jaring apung (KJA) (water based system) sehingga menyebabkan rendahnya tingkat kelangsungan hidup. Dengan demikian, dalam rangkaian proses budidaya diperlukan pengembangan unit pendederan di dekat lokasi pembesaran (Dennis et al, 2020).…”

Pendederan ikan kerapu cantik umumnya dilakukan dengan pergantian air rutin setiap hari sehingga rentan terhadap penurunan kualitas air dan kinerja produksi. Pendederan ikan kerapu dengan sistem resirkulasi dan bioremediasi diharapkan dapat meningkatkan kinerja produksi melalui perbaikan kualitas air. Penelitian ini bertujuan untuk menganalisis pendederan kerapu berbasis recirculating aquaculture system (RAS) dan bioremediasi untuk meningkatkan efisiensi akuabisnis. Penelitian ini dilakukan selama 40 hari menggunakan rancangan acak lengkap dengan tiga perlakuan dan empat kali ulangan. Penelitian menggunakan tiga perlakuan sistem pemeliharaan, yaitu sistem konvensional tanpa resirkulasi dan tanpa bioremediasi (SK), sistem resirkulasi tanpa bioremediasi (RAS), serta sistem resirkulasi dan bioremediasi (RB). Ikan yang digunakan pada penelitian adalah benih kerapu cantik dengan panjang awal rata-rata 3,6±0,2 cm dengan padat tebar 500 ekor/m3. Hasil penelitian menunjukkan bahwa tingkat kelangsungan hidup dan laju pertumbuhan panjang mutlak terbaik didapatkan pada sistem resirkulasi dengan bioremesiasi sebesar 94,8±0,37%, dan 0,1098±0,0029 cm/hari. Usaha pendederan ikan kerapu dengan sistem resirkulasi dan bioremediasi mampu meningkatkan keuntungan 41,76% dan 8,81% lebih efisien dari sistem pergantian air rutin.
