“…Low growth of fingerlings in higher density rearing may be because of increased competition for food and space (Bolasina et al . ; Chakraborty & Mirza ; Coulibaly, Ouattara, Koné, N'Douba, Snoeks, Gooré Bi & Kouamélan ), social stress (Zeng et al . ) or social interaction (Irwin et al .…”

With the objective to develop an indoor tank seed rearing system for pearlspot (Etroplus suratensis), effects of three stocking densities in presence or absence of soil base were evaluated on growth, weight variation, survival and body composition in a 60‐day trial. The experiment had a 3 × 2 factorial design with three levels of stocking density (150, 300 and 450 fish m−3) and two levels of soil base (with and without) in triplicates. Pearlspot fry (27.5 ± 0.5 mm/0.39 ± 0.02 g) were stocked in experimental tanks (Length×Breadth×Height: 0.65 × 0.50 × 0.48 m) and fed with a formulated diet containing 29.85% crude protein. Increasing the stocking density from 150 to 450 fish m−3 significantly decreased the growth (average body weight and total length), daily weight gain, specific growth rate and survival (P < 0.001) and increased the feed conversion ratio (P < 0.01). Significantly lower growth and survival were observed in treatment having soil base compared with that of without soil base (P < 0.001). However, coefficients of variation at harvest weight and body composition of fingerlings were independent to stocking density and presence or absence of soil base (P > 0.05). A significant positive interaction effect of stocking density and presence or absence of soil base was observed on average body weight (P < 0.05) and survival (P < 0.001) of pearlspot fingerlings. This study suggests that stocking density of 150 fish m−3 without soil base in tanks would be appropriate for raising pearlspot fingerlings in brackishwater indoor seed rearing system.

“…In the present study, initial stocking density of the fish was 500 fish/m 3 ; however, reducing fish density may increase growth of the fish. Because the availability of natural food could decrease at the high fish densities and possibly result in nutrition deficiencies (Coulibaly et al, 2007). In conclusion, an extensive net cage culture in nutrient-enriched pond shows a high potential in early nursing of Nile tilapia.…”

To investigate the potential of extensive net cage culture for Nile tilapia (Oreochromis niloticus) fingerlings, an experiment was conducted in net cages suspended in a fertilized pond. Mixed-sex population of Nile tilapia with an average initial body weight of 0.065 g was used to stock in experimental cages. Four treatments; non added-substrate without supplemental feeding (NSNF), non added-substrate with supplemental feeding (NSAF), added-substrate without supplemental feeding (ASNF), and added-substrate with supplemental feeding (ASAF) were tested. The results indicated that addition of substrates which gave an additional submerged surface area of approximately equal to the total cage surface area did not show significant effect on the growth (p > 0.05). The fish gross yield obtained from non added-substrate cages without supplemental feeding was 1.22 kg/m 3 for a 56-day period.

“…Berdasarkan pengamatan selama penelitian, optimalnya pertumbuhan bobot pascalarva ikan semah pada padat tebar 10 ekor/L diduga karena mampu memanfaatkan ruang dan makanan dengan lebih baik sehingga berdampak positif pada pertumbuhan ikan, sedangkan rendahnya nilai pertumbuhan bobot yang diperoleh pada padat tebar 15 dan 20 ekor/L diduga karena ruang menjadi sempit sehingga menghambat ikan untuk tumbuh optimal. Penelitian ini serupa dengan penelitian yang dilakukan pada ikan uceng (Prakoso et al, 2016), African catfish (Coulibaly et al, 2007), dan silver perch (Rowland et al, 2006).…”

ABSTRAKIkan semah Tor douronensis (Valenciennes, 1842) merupakan ikan asli perairan Indonesia yang memiliki potensi untuk dibudidayakan sebagai ikan konsumsi maupun ikan hias. Tujuan penelitian ini adalah mengevaluasi produktivitas (pertumbuhan, sintasan, dan biomassa) pascalarva ikan semah berdasarkan padat tebar berbeda (10, 15, dan 20 ekor/L) sebagai kegiatan awal domestikasi. Penelitian dilakukan di Instalasi Penelitian Plasma Nutfah Perikanan Air Tawar Cijeruk, Bogor dan dilaksanakan secara eksperimental menggunakan rancangan acak lengkap dengan tiga perlakuan dan tiga kali ulangan. Pascalarva yang digunakan berukuran panjang 1,02 ± 0,06 cm dan bobot 0,69 ± 0,08 mg; merupakan hasil pemijahan secara induksi hormon dari induk hasil tangkapan alam yang diadaptasi selama dua tahun di kolam percobaan. Pemeliharaan dilakukan dalam akuarium berukuran 40 cm x 30 cm x 30 cm dengan volume air 15 L. Selama 40 hari pemeliharaan pascalarva diberi pakan alami berupa Artemia secara at-satiation dengan frekuensi tiga kali sehari (pagi, siang, dan sore). Hasil penelitian menunjukkan bahwa performa pertumbuhan bobot, laju pertumbuhan harian, dan sintasan tertinggi (P<0,05) didapatkan pada perlakuan padat tebar 10 ekor/L dengan nilai berturut-turut 34,31 ± 5,29 mg; 9,80 ± 0,37 %/hari; dan 95,55 ± 1,68%. Hasil penelitian ini merupakan informasi awal produktivitas ikan semah dalam proses domestikasi dan budidaya yang berkelanjutan. 34.31 ± 5.29 mg, 9.80 ± 0.37 %, and 95.55 ± 1.68% respectively. This result is preliminary information on productivity of mahseer for domestication, and sustainable aquaculture.
