Vannamei shrimp (Litopenaeus vannamei) is a commodity that is expected to not only increase options for farmers but also sustain the rise of shrimp farming business in Indonesia. One important factor in shrimp farming is the availability of feed. In addition to the availability of natural feed during cultivation, stocking density is also very influential in the survival rate and growth of shrimp vannamei. The research was conducted in September-December 2016 farms Bonea Village District of Lasalepa Muna with Test the different dosages with different stocking density. The study used a Random Group Factorial, which is based fertilization (Factor A) with three levels and stocking density (Factor B) as many as three levels, each with three replications so that all 27 units experimental unit. The results showed that the combination of factors dose of 0.7 g of urea + 0.9 g TSP and stocking density factor of 10 individuals per container provides prawn post larvae growth vannamei most excellent and a combination of factors Urea fertilizer dosage of 0.9 g TSP + 1.1 g and stocking density factor of 20 individuals per container provides a survival rate of post larvae vannamei most good. Water quality media for research in the range that is optimal for the growth and survival of post larvae vannamei.

The present study evaluated the effects of stocking density on water quality parameters, growth performance and survival rate of white leg shrimp Litopenaeus vannamei, reared in fiberglass tanks, without water exchange. Three stocking densities (50, 100 and 200 shrimp/m2) were tested. Each treatment consisted of three replicates fiberglass tanks (500 L). The shrimp were fed ad libitum four times per day with a commercial pellet (40-42% protein). After an 8-week trial, concentrations of nutrients in the culture tanks showed an increasing linear relationship with increasing stocking density. The growth performance of shrimp in low stocking densities was significantly greater than that in high stocking densities. The results from this study demonstrate that with increasing the stocking density the production of shrimp increased but in a low final weight and survival compared to low stocking density.

Study Results

The larvae of white leg shrimp (Litopenaeus vannamei Boone, 1931) at phase nauplii 6 fed with a stocking density of 150 pcs per litre and 3 formula including formula 1 with dry microalgae Spirulina + artemia as main ingredients, formula 2 with microalgae Thalasiosira weissflogii + artemia as main ingredients and formula 3 with microalgae Thalasiosira pseudonana + artemia as main ingredients. Experiments were carried out in 18 tanks fifty-litre composite at Quang Binh branch of C.P Vietnam Corporation. The study results show that, with formula 3, white leg shrimps larvae at zoea stage have the highest growth and survival rates (86.57 %), followed by formula 2 (76.03 %) and finally formula 1 (67.90 %). White leg shrimps larvae at zoea stage in formula 3 have the shortest metamorphosis time (78.61 hours), followed by formula 2 (83.25 hours) and the longest in formula 1 (94.10 hours).

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.

Abstract The nursery of shrimp is an intermediate effort to connect hatchery and grow-out process, wherein shrimp fry was rear in a controlled process in a certain time before reared on pond. The study was aimed to evaluate the growth and, survival rate of white shrimp (L. vannamei) under different stocking density in nursery phase on pond. The nursery of L. vannamei was carried out at experimental pond installation of Research Institute for Coastal Aquaculture and Fisheries Extension (RICAFE) in Maros-South Sulawesi using a 5.5 x 11 m2 size of ponds, which was equipped with a bottom aeration system. The water depth of pond was 40 cm. Pond preparation was done by pond repairing, maintaining, drying, and eradicating using 20 ppm of saponin, flushing and water filling gradually until maximum of water level. The fry of L. vannamei (PL-10) with an average initial weight of 0.002g, which obtained from hatchery, were stocked. The treatments were stocking density of L. vannamei fry namely 1,653 individuals/m3 or 40,000 individuals/pond (A) and 909 individuals/m3 or 22,000 individuals/pond (B). Commercial powdered feed was given 3 times/day in 50–100% of biomass weight calculation base. The parameters observed were growth rate, survival rate of white shrimp and water quality condition. The results showed water quality variables including temperature, dissolved oxygen, pH, salinity, and alkalinity were in a suitable range for growth and survival of L. vannamei. The survival rate of L. vannamei in 21 days nursery was 86.40-95.61% and the final weight ranging from 0.292 to 0.320g/ind.

This research aimed to determine the stocking density that support the best growth and survival rate of carp cultivated in aquaponic systems, and to study the water quality of carp culture with different stocking densities in aquaponic systems. The study used 12 aquaria measuring 40x40x40 cm each (water volume of 50 liters). The experimental fish are carp (Cyprinus carpio) weighing in average of 3.5 g/individual.  The fish were cultivated with different stocking densities as treatment, including A = 4; B = 7; C = 10 and D = 13 individuals/aquarium.  The fish were fed with pellet at 5%/body weight/day with a feeding frequency of two times a day. The study was conducted for 4 weeks. Data consisting of daily growth, survival and water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite and nitrate) were measured once a week. The data obtained were analyzed by ANOVA. The results of the study showed that the difference in stocking density had no significant effect on the growth and survival of carp.  Water quality was in a reasonable range to support the growth and survival of carp cultivated with aquaponic systems.Keywords: cultivation, carp, aquaponics, stocking density, growth
