Addition of artificial shelter for spiny lobster grow out reduces cannibalism while addition of net in spiny lobster rearing tank can increase mobility space. This study aimed to determine the optimum of shelter net size on growth, survival rate and health of spiny lobster grow out. This study used completely randomized design with three treatments and three replications; analyzed by ANOVA. The rearing was conducted using 9 fiberglass tank 1000 liter in volume. This research used scalloped spiny lobster, with average body weight (BW) 8.56±1.23 g and total length (TL) 7.39±0.114 cm, in stocking density 50 lobster/tank. Three shelter net sizes as treatments, i.e.: A: shelter net size of 4 time of bottom area (4 m2), B: size of 2 time of bottom area (2 m2) and C: without net addition. Feeding were twice a day, with dry pellet 1% biomass/day and trash fish and mussel meat (2:1) 10% biomass/day. The sampling of survival rate, total length and body weight were conducted every 15 days; while total haemocyte (THC) and BRIX index on the end of experiment. For supporting data was observed of water quality parameters: salinity, temperature, pH, DO, nitrite and ammonia. The result show that the survival rate on experiment during 75 days rearing, was significant different (P<0.05) among treatments. The best survival rate was on treatment A (4 time of bottom area) with survival rate (93.94±2.62%), followed by treatment B (2 time of bottom area) (80.56±2.88%: and treatment C (without net addition) (68.78±4.67 %). The grow of body weight and total length show that highest on treatment B with body weight and total length in the end of experiment was 37.77±1.896 g and 10.30 ±0.361a cm; followed by treatment A (35.58±0.405 g and 10.15 ±0.146 cm) and lowest in C (35.34±2.061 g and 10.04 ±0.265 cm); but from statistic analyze not significant different among treatment (p>0.05). Addition for shelter net size of 4 time of bottom area net more suitable for scallop spiny lobster reared in fiberglass tank; because can increased the survival rate and reduced the cannibalism.

ABSTRAKKetersediaan induk dalam suatu usaha pembenihan memiliki peran yang sangat penting. Namun demikian, ketersediaan induk yang berasal dari alam sangat terbatas jumlahnya, sehingga perlu dilakukan penyediaan calon induk yang berasal dari hasil budidaya. Ikan kerapu bebek Cromileptes altivelis Valenciennes, 1828 turunan pertama (F-1) dan turunan kedua (F-2) sudah dapat diproduksi dari hasil budidaya, namun benih turunan ketiga (F-3) belum dapat diperoleh. Penelitian ini bertujuan untuk mendapatkan karakteristik morfologis dan pertumbuhan larva ikan kerapu bebek F-3 sebagai calon induk F-3, serta tingkat keberhasilan produksi benihnya. Pemeliharaan larva dilakukan dalam hatchery hingga larva menjadi benih. Parameter yang diamati meliputi panjang total dan panjang duri sirip larva, berat tubuh larva serta sintasan dan jumlah produksi benih. Hasil penelitian menunjukkan bahwa panjang total larva umur 5, 15, 25 dan 35 hari, masing-masing adalah 3,20±0,07; 4,42±1,11; 8,35±1,12 dan 12,51±3,23 mm. Duri sirip mulai terukur pada larva umur 15 hari. Berat larva umur 30 hari adalah 0,11±0,04 g. Pola pertumbuhan panjang total dan berat tubuh larva adalah eksponensial, sedangkan pola pertumbuhan duri siripnya adalah linier. Masa pemeliharaan larva hingga menjadi benih adalah ± 40 hari. Jumlah benih ikan kerapu bebek F-3 yang diproduksi dalam satu kali siklus pemeliharaan berkisar 440 hingga 2.300 ekor dari 50 ekor induk dan 3 kali siklus pemijahan dengan tingkat kelangsungan hidup 1,30% hingga 8,80%. Hasil penelitian ini mengindikasikan bahwa ikan kerapu bebek F-3 dapat diproduksi dari hasil budidaya seperti halnya pada F-1 dan F-2. ABSTRACTBroodstocks are the most important part of humpback grouper culture, but their availability in nature are limited. Therefore, it is necessary to produce broodstock candidates from culture. The first (F-1) and the second (F-2) generation of humpback grouper have already been produced but the third generation (F-3) production is still on the way. This study was conducted to find out morphological characteristic of the third generation (F-3) of humpback grouper larvae as the candidate of the third generation of broodstock, larval growth and the success rate of seed production. Larvae rearing was done in hatchery until larvae metamorphosed to be seeds. Observed variables including larval total length and spine length, larval body weight, survival rate and the juvenile productions. The study result showed the total length of 5, 15, 25 and 35 days old larvae were 3.20±0.07; 4.42±1.11; 8.35±1.12 and 12.51±3.23 mm, respectively. The spine began measured on 15 days old larvae. The body weight of 30 days old larvae was 0.11±0.04 g. The growth pattern of larval total length and body weight were exponential, while the growth of spine was linear. Rearing period from larvae to juveniles was 40 days. Number of F-3 seed production of humpback grouper produced from once rearing cycle range between 440 and 2,300 fish and the survival rate range from 1.30% up to 8.80%. Therefore, this study could indicate that seed of F-3 humpback grouper can be produced as those of F-1 and F-2.

Three nursery rearing trials were conducted to overcome the inconsistent survival of megalopa of the giant mud crab Scylla serrata (Forskal, 1775) during metamorphosis to crab instar. In the first trial, 3-4 days old megalopa (4.73 mg mean body weight) were stocked in hapas erected in outdoor brackishwater ponds and indoor fiberglass (FRP) tanks at densities of 500 nos. m-2 and 1 no. l-1 respectively and reared for 15 days using minced clam meat (Meretrix casta) as feed. Outdoor hapas were provided with seaweed, Gracilaria tenuistipitata as shelter. Mean survival rate of crab instar following three consecutive runs were significantly higher (p<0.05) for megalopa reared in outdoor hapas (57.7±2.7%) over indoor FRP tanks (24.1±2.2%). To ascertain the life stage that yields optimal survival on weaning from indoor hatchery to ponds, zoea 5 (Z5) and megalopa 1-day old (M1), 2-day old (M2), 3-day old (M3) and 4-day old (M4) were reared in hapas for15 days and fed on minced clam meat. Three day and 4-day old megalopa demonstrated significantly higher survival rates (p<0.05) of 62.3±3.08% and 69.6±2.35% respectively to crab instar stage at conclusion of the trial. Megalopa (3-4 days old, 5.05 mg mean body weight) were stocked to 100 l tanks (stocking density - 1 no. 4 l-1) and reared for a period of 8 days using different feeds viz., artemia biomass (T1), minced clam meat (T2), crab larvae (T3) and artemia nauplii (T4) in the third trial to evaluate various production parameters. Crab instar conversion rate (number of crab instars/number of megalopa stocked × 100) was significantly higher (p<0.0001) for megalopa fed using artemia biomass (T1) and minced clam meat (T2) at 74.66±5.81% and 72.00±2.30% respectively. Results of the present study indicate that, high density rearing (500 no. m-2) of megalopa (3-4 days old) in outdoor hapas provided with seaweed refuge for short periods (15 days) would yield higher survival rate to crab stage. Nursery rearing of megalopa in ponds reduces the hatchery phase in mud crab larval rearing and maximise production of crab instars.

ABSTRACT According to Indonesian Standard Quality, the optimal seed production of orange spotted grouper (Epinephelus coioides) has been unsuccessful due to the problems occurred during larval rearing period. Efforts on mass rearing of larvae has been carried out in this study to optimize the natural feeding (rotifer). The purpose of this research was to obtain the information about an appropriate duration time for natural feeding (rotifer) to produce higher survival rate. The treatment for providing rotifers on larvae (days after hatching/DAH) i.e., (A) 20 days, (B) 25 days, (C) 30 days, and (D) 35 days. Rotifers were enriched with DHA Selco. Experiment used fiber tanks with 1 m3 capacity with a completely randomized design (CRD) and three replicates. The larvae was reared to achieve the juvenile phase (D-45). The best results from 1 m3 tanks were then reared using concrete tanks of 6 m3 and 10 m3 capacities. The results showed that feeding of rotifers up to 25 DAH larvae on fiber tanks (1 m3) produced the hughest survival rate (7.63 %). Meanwhile, the mass reared in 6 m3 and 10 m3 concrete tanks produced  survival rate of 4.9±3,54% and 8.8±2.26%, respectively. The homogenous size was relatively high (80%) and the seed abnormality was relatively low (0.4%).   Keywords: rotifers, feeding time, Orange Spotted  grouper larvae, Epinephelus coioides

Attempt has been taken to develop intensive tank culture technique providing natural environment for Stinging catfish (Heteropneustes fossilis) inside tank to increase survival rate as well as production. The experiment was conducted for a period of 150 days in two tanks (T1 and T2) of 300 m2. Fish fries with a mean weight and length ranged from 1.02 to 2.2 g and 2.7 to 3.5 cm were stocked in T1 and T2, respectively. Stocking density of fingerlings were 1, 25,000 and 1, 50,000 per Ha in T1 and T2, respectively. Commercial pelleted feed was supplied to tank reared fish twice daily at a rate of 3-10% of body weight per day and later feeding rate was adjusted based on body weight by sampling. Important water quality parameters (temperature, DO, pH, transparency, ammonia and nitrate) were recorded weekly throughout the culture period. Survival rate was 87% and 84% in T1 and T2, respectively. Mean final weight were 41.73 ± 2.09g and 40.6 ± 0.90 g in T1 and T2, respectively. Length-weight relationship indicates that the growth rate was always higher in T1 followed by T2. Results showed that net yield was relatively higher in T2 (5115.35 ± 113.13 Kg/ha) than T1 (4537.12 ± 227.4 Kg/ha). In case of production, there was significant difference (p < 0.05) between two treatments. This experiment demonstrated the potential of H. fossilis production through new technique of tank culture system. However, more research is needed using local feed ingredients with higher stocking density. Bangladesh J. Zool. 47(1): 107-119, 2019

This study was conducted to investigate and compare the growth performance of four Tilapia strains in hapa nursing with the aim to find out the best strain of tilapia. The research was conducted by four treatments with five replicates each. The tilapia fry were collected from, BFRI source from BFRI HQ, Mymensingh stocked in Treatment-1; unknown source from Hi-Tech Tilapia Hatchery Dagoanbhuiya, Feni in Treatment-2, Philipine strain from Green Field Tilapia Hatchery, Laxmipur in Treatment-3 and fry from Breeding Cohort, Sonar Bangla Hatchery, Bamna, Barguna in Treatment-4. The Individual stocking weight (g) of fry was average 0.01g. The fries were stocked in 12 hapa at same stocking density of 1200 fish/m2. Each of the hapa was 2m × 1m × 1m size and fixed in an earthen ponds. Supplementary feed with 31.29% of protein level consisting of rice bran (25%), mustard oil cake (15%), wheat flour (30%) and fish meal (30%) was given at the rate of 40% of their body weight per day manually, four times a day at the beginning of the experimental period and reduced to 25% of their body weight and continued up to harvesting period. The results showed that fry of Treatment-4 strain was the best strain and had significantly (p < 0.05) higher final mean body weight (FMBW), mean body weight gain (MBWG), specific growth rate (SGR) (9.75%), gross yield (GY) (2.13) and Net yield (NY) (2.12) than the Treatment-1 , Treatment-2 strains and Treatemnt-3 strain. Treatment-4 strain had the fastest growth rate, whereas the lowest performing strain was that from Treatment-2. We also analyzed survival rate of the fish from stocking to harvest, survival rate was highest in Treatment-4 strain (80%) where lowest is Treatment-3. Treatment-4 stain also showed the best feed conversion ratio (FCR) 1.62 than others. Considering the overall performance it can be concluded that tilapia strain collected from Breeding Cohort source is best among the four strains. However, further research may still be needed to compare more strains from different water body to evaluate the genetic potential for Tilapia.International Journal of Natural Sciences (2015), 5(2) 98-106
