The research aims to determine the best stocking density in the maintenance of Siamese catfish seedlings based on the influence exerted on the survival of Siamese catfish seeds and improving water quality in the recirculation system. This research was conducted at the Green House Ciparanje FPIK Unpad Jatinangor in August 2019. Maintenance activities are carried out in a 70x70x70 cm fiber equipped with a recirculation system and filled with 150 L of water per fiber. The study was conducted with four stocking solid treatments as follows 375 fry/fiber (treatment A); 450 fry/fiber (treatment B); 525 fry/fiber (treatment C); and 600 fry/fiber (treatment D). Siamese catfish fry is 1 inch in size with an average weight of 0.307 grams. The parameters observed were the survival of Siamese catfish fry and water quality. Water quality measurements include temperature, degree of acidity (pH), and ammonia (NH3). Water quality testing was carried out at the Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. During the study, there was no exchange of water or siphon. The method used in this research was analyzed descriptively and compared the results of survival rate fish and water quality parameters toward the Indonesian National Standard (SNI). The results showed that the best stocking density was 600 fry/fiber with a survival rate of 100% Siamese catfish and the ammonia value at the beginning of maintenance was 0.140 mg/L and the end of maintenance decreased to 0.137 mg/L.

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.

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.

Increased temperature, decreased water level and reduced culture period of the ponds are considered as major problems for aquaculture promotion in drought prone Barind area of Bangladesh. In order to address these problems, an experiment was conducted to optimize the stocking weight for carp polyculture ponds in Tanore upazila of Rajshahi district, Bangladesh. Three different stocking weights were tested under three treatments (T1: 25±0.12g; T2: 50± 0.15g; and T3: 100±0.19g), each with three replications. Fish growing period (July-December), carp species (C. catla, H. molitrix, A. nobilis, L. rohita and C. mrigala), stocking density (7,410 fishes/ha), lime and ash treatment, fertilization and feeding were same for all the treatments. Water quality (water temperature, dissolved oxygen, transparency, pH and alkalinity) and fish growth parameters were monitored monthly. Mean values of water quality parameters were found within the suitable range for fish culture. Treatment T3 varied more significantly (P<0.05) than that of other treatments for the mean values of final weight, weight gain, specific growth rate, survival rate and yield of fish. Net benefit of carp polyculture was also found significantly (P<0.05) highest with treatment T3.

In Indonesia, the use of such recirculating aquaculture systems (RAS) is rapidly increasing. The purpose of this study was to investigate the growth, blood chemistry, and water quality of snakehead fish (C. striata) maintained in RAS at varied stocking densities. The RAS was established at the Bogor-based Research Institute for Freshwater Aquaculture and Fisheries Extension. The study employed a completely randomized study using 3 various densities: A). 1 individual L-1, B). 3 individual L-1 and c). 6 individuals L-1, each using three replications. The average weight and length of snakehead fish used is 1.50±0.63 g and 6.20±0.94 cm. Growth performances such as survival rate, weight, and length gain, food conversion ratio, specific growth rate, and final biomass were observed during the research. Blood chemistry parameters analyzed were blood glucose, triglycerides, and total protein. The water quality characteristics were evaluated: pH, temperature, dissolved oxygen, total ammonia nitrogen, nitrate, nitrite, and orthophosphate. The analysis indicates that snakehead fish's growth performances and blood chemistry parameters differed considerably (P<0.05) across all density treatments, with 3 individual L-1 showing the best growth performances. The RAS utilized in snakehead fish culture kept the water quality parameters steady throughout the study.

Culture of Tilapia (Oreochromis niloticus) with high stocking density and feeding can cause a decrease in water quality due to the accumulation of metabolic waste such as ammonia which is toxic for fish rearing. A zeolite filter is needed which can reduce ammonia levels until it is not harmful to fish survival. This research was conducted in February-April 2020 at the Aquaculture Environmental Quality Laboratory, Fisheries and Marine Faculty of Riau University. The purposed of this study was to determine the effect of using zeolite on Ammonia (NH3) and determine the appropriate dose for Tilapia (Oreochromis niloticus) rearing. The research method was a Completely Randomized Design (CRD) one factor with 4 levels of treatment (P0: Control without the use of filters, P1: Use of zeolite 5.68 g/L, P2: Use of zeolite 11.37 g/L, P3: Use of zeolite 17.05 g/L). The appropriate treatment for Tilapia rearing is P3 (Zeolite 17.05 g/L) with TAN value is 0.2616 mg/L, Ammonia 0.0018 mg/L, TAN reduction is 59%, and Survival Rate of fish is 88.88%.
