PRODUCTION OF WHITE SHRIMP Litopenaeus vannamei IN FLOATING CAGE SYSTEM  WITH DIFFERENT STOCKING DENSITY AT THOUSAND ISLAND STRAIT

The aim of this study was to analyze the survival rate, growth, and haemolymp glucose level of white shrimp as a physiological responses at floating cage cultured on different stock den-sity, in Seribu Islands Strait. White shrimp used in this study contained approximate weight of 1.0±0.06 g and length of 5.0±0.03 cm from Nusa Karamba Hatchery in Seribu Island. White shrimp was maintained in 90 days, feed with ±36.28 % protein content 4 times each day with feeding rate (FR) of 7%. Water qualities and shrimp growth measurements was conducted every 10 days. Haemolymph glucose sam-pling was performed in the beginning and at the end of the experiment. Result showed that treatment with stock densituy of 250 shrimp/m2 had a better survival rate of 30.33% and feed conversion ratio of 1.13 than other treatments. Phy-siological response in the form of glucose hemolim also showed a better response in the 250 ind./m2 stock density of 41.87 mg/dl indicating that the white shrimp did not experience a sig-nificant stress.

The study aimed to evaluate the combination between commercial feed and fermented tofu waste feeding for growth, survival rate and production of red Tilapia Oreochromis niloticus in pond. The study was conducted in Experimental Pond Installation of Research Institute for Coastal Aquaculture, Maros, South Sulawesi, using eight ponds with 2,500 m2 in size. Red Tilapia fingerlings (±8 cm in length) were reared for 112 days with 1 individu/m2 of stocking density. The feeding treatments were of 100% commercial feed (A), 75% commercial feed + 25% fermented tofu waste (B), 50% commercial feed + 50% fermented tofu waste (C), and 25% commercial feed + 75% fermented tofu waste (D). Feeding frequency was given twice a day using concentration 10% of biomass weight in the first month, and decreased by 3% of biomass weight in the fourth month. Experimental was designed by a completely randomized designed consisted of four treatments and two replications for each treatment. Observed variables were growth, survival rate, feed conversion ratio, production, and water quality. Present study indicated that different levels of combination of commercial feed and fermented tofu waste had significant effect on growth (P<0.05), but did not have significant effect on survival rate, production, and feed conversion ratio (P>0.05). Feeding by combination of 75% commercial feed + 25% fermented tofu waste could be utilized optimally by Tilapia. During experiment, pond water quality was in conducive condition to support the growth and survival rate of red Tilapia.

ABSTRACTThe aim of this research was to determine optimum stocking density for growing-out of spiny lobster Panulirus sp. in controlled tanks that conducted for 30 days. The experimental spiny lobsters have the initial average weight of 130.39 ± 0.32 g and initial average total length of 140.70 ± 0.06 mm. This study used completely randomized design with three different stocking densities (KT10: 10 ind/m3; KT18: 18 ind/m3; and KT26: 26 ind/m3) and two replications. The parameters observed in this study included water quality (temperature, pH, salinity, dissolved oxygen, and total ammonia nitrogen), physiological responses (total haemocyte count, haemolymph glucose, and frequency of molt), and production performances, such as growth, specific growth rate, feed conversion ratio, and survival rate. The results showed that the spiny lobster could be reared in high stocking density in controlled tanks. Water quality during the study in each treatment was; temperature 26.56–28.65oC, salinity 29.7–33.6 g/L, pH 7.5–8.5, dissolved oxygen 6.15–6.58 mg/L, and total ammonia nitrogen 0.11–0.34 mg/L. The best stocking densities for spiny lobster was 18 ind/m3 (KT18) with 2.5‒3.5×106cells/mL total haemocyte counts, 24.6‒28.3 mg/dL haemolymph glucose, and 38.37 ± 3.20% frequency of molt. The final average body weight and length were 145.06 ± 0.42 g and 142.77 ± 0.19 mm, respectively. The survival rate reached 86.11 ± 3.92% with a specific growth rate 0.35 ± 0.01%/day, and feed conversion ratio 7.87 ± 0.31.Keywords: high stocking density, Panulirus sp., physiological responses, productivity.

This study was carried out to assess the effect of different cage stocking densities on the production performance of Nandanam quail III reared up to 42 days. Three hundred day old Nandanam quail III were randomly assigned to 2.5 x 1.5 ft cages and distributed with 3 treatments (20, 25 and 30 quails per cage or 0.17, 0.14 and 0.11 sq. ft per quail, respectively) and 4 replicates. There were significant differences among treatments for bi-weekly body weight, feed consumption, feed conversion ratio and net profit per bird. There was a reduction (P>0.05) in body weight with the increase in stocking density and the 4th and 6th week body weight were 144.17±3.84, 128.55±3.63 and 108.03±2.69 g; and 216.86±5.95, 207.76±4.01 and 197.27±3.81 g, respectively. The feed consumption per bird (g) up to 42 days were 665.69±0.01, 532.19±0.01 and 443.23±0.01 respectively. Better feed conversion ratio (2.57 and 2.25) and net profit per bird (Rs. 4.48 and 7.15) were observed where the birds reared at the cage stocking density of 0.14 sq.ft and 0.11 sq.ft per bird, respectively. This study concluded that the cage stocking density between 0.11 and 0.14 sq.ft per bird will be more economical for rearing Nandanam quail III in cage system of rearing up to 42 days of age.

The Impact

This study aimed to examine the impact of dietary salt-based mineral and phosphorus supplements on mean body weight, survival rate, and feed conversion ratio of Litopenaeus vannamei (white shrimp) reared in brackish water. The experiment was performed randomized design with three replicates in each treatment used twelve 40 L rectangular polymethyl methacrylate containers reared 45 days. The four treatments in this study were based on the concentration of salt-based mineral and phosphorus supplements (control or 0 ppm, one ppm, two ppm, and three ppm) in dietary of white shrimp. The results showed that using salt-based mineral and phosphorus supplements in dietary of white shrimp positively impacts mean body weight, survival rate, and feed conversion ratio. Increasing the concentration of salt-based mineral and phosphorus supplements increased mean body weight and survival rate and reduced feed conversion ratio of white shrimp. The mean body weight, survival rate, and feed conversion ratio of white shrimp were achieved with three ppm of dietary salt-based mineral, and phosphorus supplements reared 45 days was 5.98 gr, 88.57%, and 1.45, respectively.

Shrimp Cultivation

The failure of tiger shrimp (Penaeus monodon) farming could make farmers stop their cultivation activities. As an alternative, vannamei shrimp cultivation gives hope for productive, profitable, and sustainable cultivation. The development of shrimp farming in Tegal City is carried out through simple methods, intensive technology, and the use of Busmetik technology or mini-scale shrimp farming on plastic ponds. The high demand in the shrimp market continues to encourage farmers to increase their productivity by increasing stocking density. The purpose of this study is to determine the performance of vannamei shrimp cultivation which is cultivated intensively including yields, survival rate (SR), feed conversion ratio (FCR), and shrimp growth in Tegal City, Central Java Province. The research was conducted from July to October 2019. The research method used was a case study with 16 plots of ponds, and the average area of the pond was 1000 m². Based on the results of the calculation, it can be seen that the average yield is 1,603 kg per pond with a stocking density of 100 fish/m², a survival rate (SR) is 85.6%, a feed conversion ratio (FCR) is 1.41 and the shrimp growth is 0.16 grams per day. Economically, based on the Benefit-Cost Ratio (B/C ratio) of 1.46, vannamei shrimp cultivation in Tegal City is profitable so that shrimp farming can be carried out sustainably.
