The efficacy and suitability of dietary whole wheat flour supplementation was evaluated on the growth performance and survival of rohu (Labeo rohita). The study was conducted in 12 experimental aquaria at the Wet Laboratory, Department of Aquaculture, Bangladesh Agricultural University, Mymensingh. A total of 180 fingerlings of mean initial weight of 1.744±00 g were stocked at the same stocking density (268 fingerlings/m3). Four different treatments (T1, T2, T3 and T4) each with three replications were performed having different level of whole wheat flour such as 0% whole wheat flour (T1), 5% whole wheat flour (T2), 10% whole wheat flour (T3) and 15% whole wheat flour (T4). Feeds were supplied at 5% body weight twice daily in the morning at 9.00 am and in the afternoon at 5.00 pm throughout the study period. The rations were adjusted every week when new weights of the fish for various experimental aquariums were determined. At the end of the 63 days study period, the growth performance parameters such as mean final weight (g), weight gain (g), percent weight gain (%), specific growth rate (%/day) and the best feed utilization in terms of food conversion ratio were found highest at treatment 4 where fishes were fed with inclusion of 15% whole wheat flour and lowest was found at treatment 1 (fed with inclusion of 0% whole wheat flour). Water quality parameters were within the acceptable range and survival rate was found 100% in all treatment. Therefore, it can be concluded that treatment 4 (highest growth performance and survival rate of L. rohita with supplementation of 15% whole wheat flour containing diet) can be chosen by fish farmers for commercial culture of this species.

pH is one of the important water quality parameters in aquaculture. This study aimed to observe the growth performance and survival rate of common carp (Cyprinus carpio) Rajadanu strain reared in culture media with different pH levels. Fish (length: 3.60 ± 0.18 cm; weight: 1.68 ± 0.18 g) were stocked in nine aquariums (40 cm x 40 cm x 30 cm) for 10 days with a stocking density of 25 fish per aquarium. The treatments used were (A) pH 4-5, (B) pH 5-6, and (C) pH 6-7, with three replications. A commercial feed containing 28% protein was given daily and as much as 3% of the total biomass. The observed data were analyzed using variance analysis (ANOVA), followed by Duncan test. The results showed that the pH treatments did not affect the growth (length and weight) and survival rate of common carp Rajadanu strain (P>0.05). The best growth was achieved by the fish group reared in water with a pH range of 6-7 (length = 0.38 cm; weight = 0.17 g). The highest survival was attained by the fish group reared in water with a pH range of 5-6 (90.66%).

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.

The dietary chitosan has been largely used in the supplemental diets of terrestrial animals to improve growth and development. However, there is little information on the roles of dietary chitosan in growth and development of aquatic animals like fishes. Thus, this study aimed at determining the effects of dietary chitosan on growth performances and survival of Barbonymus gonionotus fry. A total of 600 B. gonionotus fry (2.12±0.02 g) were considered for this study. This experiment consisted of four treatments (0, 1, 2 and 3 g Kg-1 formulated feeds) and each treatment had three replications with a stocking density of 50 fry/tank. The dietary chitosan was supplied as 8% of body weight of each fry twice daily for 60 days. Fish fry treated with the dietary chitosan exhibited significant (P < 0.05) improvement in growth (body weight gain, % body weight gain, specific growth rate, and feed conversion ratio) and survival of B. gonionotus in comparison with untreated control. The water quality parameters, such as temperature, pH and dissolved oxygen showed no significant variations, and maintained suitable range throughout the study period for fish growth. Among the treatments, application of 1 g chitosan kg-1 feed showed the highest positive effects on growth and survival of B. gonionotus fry, indicating their potentials for practical application in promoting sustainable aquaculture.

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.

Blkr) is a potential fish species for aquaculture in Indonesia. However, the growth and survival rate performance can be improved by developing cultivation containers. The research objective was to determine the optimal type of cultivation container to produce high growth and survival rate. The ponds treatments used in this experiment were soil pond, hapa pond and tarpaulin pond with measuring 3 m x 2 m x 1 m. The initial fish length average was 15±1.39 cm, with the initial body weight average of 250.04±1.70 g with the stocking density of 25 individual/pond. During 120 days of the rearing period, the fish were fed with trash fish with a proportion of 30% of body weight with the frequency of feeding 2x a day. The results showed differences in the type of container significantly affected weight gain and specific growth rates but did not significantly affect survival rate. The best weight gain was found in the treatment of soil pond containers at 53.86 ± 1.10 g with a specific growth rate of 0.45 ± 0.010% body weight/day and survival rate of 85.33 ± 6.11%. Water quality in all containers still supports growth and survival rate. The results of this study can be used as necessary information in the selection of effective and efficient aquaculture containers to produce optimal sand goby culture.Keywords: sand goby; growth; survival rate; container
