Effect of shelter net sizes on growth, survivality, and health of scalloped spiny lobster, Panulirus homarus (Linnaeus 1758) reared in fiberglass tank

Abstract Scalloped spiny lobster (Panulirus homarus) is an export commodity with high economic value in Asian-Pacific markets. 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.

ABSTRACT Golden trevally fish is a prospective commodity that can be cultured and contains high economic value. The purpose of this study was to determine the best type of food for golden trevally fish growth. The larval rearing were conducted using concrete tanks with 6 m3 of volume. Three different food were used as treatments, i.e: (a) pellet micro, (b) small shrimp, and (c) trash fish. The start of experiment for larvae were reared for 30 days old. The stocking density of larvae was reared at 10 pc/l. Sampling of larvae were conducted every 7 days to measure of survival rate (SR), total length (TL) and body weight (BW). The larvae were reared with flowthrow system. At 70 days old, larvae were harvested and graded. The results showed that there was no significantly different among treatments (P>0.05) for survival rate, but the growth was significantly difference among treatments (P<0.05). The survival rate (SR) treated with trash fish was 5.38±1.20%, small shrimp 4.05±1.10%, and micro pellet 4.01 ± 1.20%. The total length and weight treated with trash fish were 5.40 ± 0.80 cm and 53±0,50 mg, respectively, while treaded with small shrimp were 4.80 ± 0.20 cm and 61±0.30 mg, and micro pellet were 4.54±0.56 cm and 48±0.40 mg, respectively.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

Stocking density is considered one of the important factors affecting fish growth. The study was aimed to compare the growth parameters of monosex tilapia at various stocking densities. The experiment was carried out during the period from 06 August to 22 December 2014. Three stocking densities were used as 125, 250 and 375 fish/dec and designated as treatment T1, T2 and T3 respectively each having two replicates. All the fishes were of same age group having average initial body weight of 1.34g. A commercial feed was supplied at the rate of 40% of the body weight and then gradually it was readjusted to 20%, 10%, 5% and 3% respectively and continued up to the end of the experiment. The water quality parameters were monitored at 14 days interval and the ranges were: temperature 19.34 to 31.40°C, pH 6.83 to 8.03, dissolved oxygen 4.78 to 6.82 mg/l and transparency 29.02 to 49.45cm.The result of the present study showed that the mean weight gain was significantly (P<0.01) highest in T1(120.58g) followed by T2(89.74g) and T3(74.58g).The average specific growth rates (SGR) was 2.590, 2.560 and 2.598 (%/day) in treatment T1, T2 and T3 respectively. There was significant (P<0.01) differences among the survival rate. The survival rate 87% was significantly highest in T1followed by 76% in T2 and 69% in T3.The fish productions were 13.25, 17.30 and 19.64 kg/decimal in T1, T2 and T3 respectively. Although the highest production was obtained in T3 but individually growth performance of monosex tilapia was highest in T1. The highest net profit was found (BDT 3,373.30) inT1compared toT2 (BDT 3,017) and T3 (BDT 2,918). The highest benefit cost ratio (BCR) was 1.79 in T1followed by 1.44 in T2and 1.28 in T3. Based on the result of present experiment, fish farmers might be suggested to rear tilapia at lower stocking density to get higher growth, survival and benefit in a short period of time.Asian J. Med.
