Tropical abalones (Haliotis asinina) is a marine gastropod that has high economic value and consumed by people in the world. In 2002, the production of abalones was 4.076 ton from total production of marine fisheries in the world 8.000 ton. The countries that produce abalone by farming are Taiwan, Cina, South Africa, Japan, Cilie, USA, Australia and New Zealand. Information about the production in Indonesia is scarce. The main issue faced by farmer is higher mortality during post larvae and juvenile. The aim of this research was to observe the influence of abalone seed density in concrete tanks regarding to growth and survival. The research was conducted in January - May 2012 Mataram Marine Bio Industry Technical Implementation Unit, LIPI. Analysis of varians showed that seed densities was not significantly different (P>0.05). The highest survival rate were in density 75 individual/tank with 11.11 % mortality. The highest growth rate were in 50 individual/tank with shell growth rate 0.21cm/14 days and seed weight was 1.23 g.Keywords: growth, survival rate, seed of abalone (Haliotis asinina), density

<p>This experiment was conducted to study the stocking density effect on growth and survival rate of giant gouramy seed in the aquarium. Fish were stocked at the density of 2.5; 5.0; 7.5 and 10 individual/l with average initial weight and length were 0.013 g and 5.56 mm, respectively. Fish were fed with silkworm (<em>Tubifex</em> sp.) <em>ad libitum</em> in the morning and evening for 22 days of experiment. Aquarium was siphoned and water was changed everyday for maintaining good water quality. Result showed that survival rate remain high in all treatment (93.5 - 95.5%). Increasing stocking density from 2.5 to 10 individual/I did not affect survival rate. On the other hand growth rate and feed efficiency decreased, while fish yield increased. Stocking density of 2,5 individual/l gave  the highest daily growth rate, individual growth rate, growth in length and feed efficiency of 12.94%, 0.0081 g/day, 16.84 mm and 12.51%; respectively. The highest value for fish yield (0,0360 g/l/day) was obtained from stocking density of 10 individual/l</p> <p>Key words: stocking density, seed, survival rate, growth rate, giant gouramy <em>Osphrenemus goramy</em></p> <p> </p> <p>ABSTRAK</p> <p>Keterbatasan pengadaan benih ikan gurame (<em>Osphronemus gourame </em>Lac.) disebabkan oleh tidak seimbangnya jumlah benih yang tersedia dengan kebutuhan usaha pembesaran. Teknik pembenihan yang digunakan sampai saat ini relatif sederhana dengan cara tradisional. Pemeliharaan gurame secara terkontrol di akuarium dapat menjawab tantangan dalam teknologi pembenihan gurame sekaligus sebagai sarana pola budidaya secara bertahap yang sedang berkembang saat ini. Produksi yang tinggi akan dicapai dengan pemeliharaan pada kepadatan yang tinggi. Pada keadaan lingkungan yang baik dan pakan yang mencukupi, peningkatan kepadatan akan disertai dengan peningkatan hasil. Jumlah ikan yang ditebar pada penelitian ini disesuaikan berdasarkan perlakuan yaitu 2,5; 5,0; 7,5 dan 10 ekor/l. Pengamatan terhadap ikan dilakukan sampai hari ke-22. Hasil pengamatan menunjukkan bahwa peningkatan kepadatan 2,5 - 10 ekor/l pada pemeliharaan benih gurame di akuarium mempengaruhi pertumbuhan, hasil dan efisiensi pakan, namun tidak berpengaruh terhadap kelangsungan hidup. Dengan meningkatnya padat penebaran, laju pertumbuhan dan efisiensi pakan semakin menurun, sedangkan hasil (<em>yield</em>) semakin meningkat. Padat penebaran 2,5 ekor/l menghasilkan laju pertumbuhan harian, laju pertumbuhan individu, pertumbuhan panjang mutlak dan efisiensi pakan tertinggi, masing-masing mencapai 12,94 %, 0,0081 g/hari, 16,84 mm dan 12,51 %.

Blacksaddled coral grouper Plectropomus laevis is an export commodity and possess high economic value in Asian markets, but the wild population is already threatened. The purpose of this study was to determine the best food for improving growth and survival rate. The nursering were conducted using 9 fiberglass tanks with 1 m3 of volume for 6 month, with three treatment and 3 replicates. Three different foods were used as treatments, i.e.: Local commersial pellet with crude protein content 50% (A), im-port  commersial pellet with cure protein content 55% (B) and trash fish (sardine) (C). The initial size of blacksaddled coral grouper seed were 2.5 cm total lengths (TL), 0.45 g body weight (BW). The stocking density of fry was reared at 250 fish per m3. A complete random design was used as an experiment design. Data was analysed using ANOVA statistics. Feeding times were twice a day at 08.00 and 15.00 local time; with dose at satiation. The samplings of fry were conducted every 15 day to measure of survival rate (SR), TL and BW. On the end of experiment was calculated economic ana-lized (BC ratio). The result showed that there was significant different (P<0.05) among treatments for SR and growth rate (GR). The better SR and GR was at treatment B with SR 96.5%, and GR 0.75g/day followed by treatment C (SR 90.5%: GR 0.54g/day) and treatment A (SR 81.5%: GR 0.42g/ day. The food conversion ratio was 1.15 in treatment A, 1.02 in B and 4.81 (wet weight) in C. From economic analized showed that the best BC ratio was in pellet 55% protein (B), followed by trash fish (C) and pellet 50% protein (A) with BC ratio of 1.75, 1.72 and 1.41 respectively.

Striped catfish Pangasianodon hypophthalmus (Sauvage, 1878) has a high economic value and relatively fast growth, so that optimum stocking density and supplement of natural ingredients, such as Curcuma domestica Val., Kaempferia galanga Linn., and Curcuma xanthorriza Robx. can increase growth and immunity. This study aimed to obtain the optimum stocking density and herbal supplement dosage in feed to increase the growth and survival rates of striped catfish. An experimental method by applying factorial design was used, i.e. the dose and stocking density factors. The dosage of herbal supplements used were 100 mL kg-1 feed (D1), 200 mL kg-1 (D2) and 300 mL kg-1 (D3). Stocking density used was 50 m-3 (P1) and 75 m-3 (P2). The fish used were 8.5±0.5 cm long and weighed 7.5±0.3 g, kept in floating cages of 1 m x 1.5 m x 1 m. Fish maintenance was carried out for 60 days with feeding frequency of three times a day, as much as 10% of body weight. The results showed that the treatment of 200 mL kg-1 dosage and 75 m-3 stocking densities was the best treatment. This treatment showed that specific growth rate, absolute weight, absolute length and feed efficiency were 4.86%, 119.07 g, 15.45 cm, 82.93%, respectively. A supplement dose of 200 mL kg-1 in feed and stocking densities of 75 m-3 could increase growth rates, survival, and feed utilization efficiency of striped catfish.

This study examined the effect of stocking density on growth and survival of tilapia cultured in biofloc technology system. Three different stocking densities cultured in biofloc technology were 6 fish/m3, 8 fish/m3 and 10 fish/m3 for 86 days in triplicate for each treatment. The stocking density of the control lot was 3 fish/m3 cultured without biofloc technology. Initial stocking weight ranged from 2–3 g/fish. The water quality parameters were monitored and regulated in the suitable ranges for biofloc technology and for the growth and development of tilapia. The results showed that specific growth rate of fish cultured at a density of 6 fish/m3 was higher than that in the treatments of 8 fish/m3 and 10 fish/m3 with the average values of 5.72%; 5.62% and 5.43%, respectively, and the specific growth rate of fish in the control treatment was 5.71%. Daily growth rate of fish cultured at a density of 6 fish/m3 was higher than that cultured at densities of 8 fish/m3 and 10 fish/m3 with average values of 3.19 g/day, 2.98 g/day, and 2.55 g/day, respectively; and the daily growth rate of the control treatment was 3.27 g/day. Survival rate of tilapia cultured at densities of 6 fish/m3 and 8 fish/m3 was 100%, whereas survival rate of tilapia cultured at a density of 10 fish/m3 was 95.75%, and it was 88.9% for the control lot. The research results provide a scientific basis to propose tilapia culture technique in biofloc technology in brackish water, with the density of 6–8 fish/m3.

Two experiments were conducted with a view to assessing the effects of stocking densities on the growth and breeding performance and larval growth and survival of Channa striatus. The first one was carried out with a view to find a suitable stocking density of Channa striatus at which they could spawn while the second experiment dealt with the effect of stocking density on growth and survival of the produced larvae. The first experiment was carried out in nine equal-sized chambers of raceway separated by netted wooden frame with an area of 1.83 ×1.12m2 each. The effective water depth in each of the raceway chambers was maintained at 1.2m. The broodfish were stocked at 4 (357.22g/m2), 6 (541.78g/m2) and 8 (719.18g/m2) at 1:1 male-female ratio and fed with washed and chopped poultry viscera twice a day and with live silver carp fry twice a week. No significant (P>0.05) difference in weight and specific growth rate was observed among the broodfish reared under different stocking densities during the experimental period of 80 days. The broodfish stocked at a density of 357.22g/m2 and 541.78g/m2 spawned naturally in their respective chambers. The fish stocked at 541.78g/m2 showed the best breeding performance. The second experiment was carried out with 4-5 days old larvae in 9 bowls of 10l capacity divided into three treatments having 20, 40 and 60 larvae each i.e. the stocking density were of 2, 4 and 6 larvae/l respectively. Larvae of treatment I which was stocked with 2 larvae/l showed significantly higher growth rate from the 7th day of the experiment and maintained the same trend up to the end of the experiment (i.e. 21st day) compared to other treatments. Larvae of treatment I also showed significantly higher health condition (13.31±0.69mg/mm) and survival rate (80.00±3.00) compared to those of the other two.
