Abstract

Asian redtail catfish Hemibagrus nemurus is one of the prospective aquaculture commodities in Indonesia. However, there are still shortcomings in completing the domestication of this species. As such, this study was conducted to observe the growth of Asian redtail catfish at different stocking densities. Fish (body weight (BW) of 21.62 ± 0.57 g) were stocked in nine different floating nets (dimension: 2 m x 2 m x 1 m) inside a concrete pond (40 m x 20 m) with three stocking density treatments (10, 15, and 20 fish/m3). Each treatment consisted of three replicates. Growth data were collected every 30 days during 120 days of rearing period which included weight gain (WG), specific growth rate in body weight (SGRBW), average daily growth (ADGBW), biomass gain (BG), feed conversion ratio (FCR), and survival rate (SR). Measured water quality parameters during the experiment consisted of temperature, pH, and dissolved oxygen. The results showed that the best growth performance was achieved by fish at the stocking density of 15 fish/m3 compared to that of fish with the stocking density of 10 and 20 fish/m3. The FCR value of fish at the stocking density of 15 fish/m3 was also significantly better than those of 10 fish/m3 and 20 fish/m3 (P<0.05). The survival rate in each treatment was not significantly different (P>0.05). This study suggests that the optimal stocking density for Asian redtail catfish fingerlings is 15 fish/m3, beyond that value, growth reduction might be expected. Further research is needed to observe its optimal stocking density in different culture systems.

Abstract

Barb (Barbonymus balleroides) considerably has economic potential as aquaculture commodity. However, there was still lack of development on aquaculture for this species. This study was conducted to observe the effect of different stocking density on growth of barb. The fish (body weight: 14.89 ± 0.13 g) were stocked in nine floating nets (dimension: 2 m x 2 m x 1 m) inside the concrete ponds with three stocking density treatments (10, 15, and 20 fish/m3). Each treatment consisted of three replications. Fish were fed on commercial pellet (30% of crude protein) as much as 3% of the biomass per day with twice a day of feeding frequency. Data of growth performances (body weight, specific growth rate, average daily growth, biomass, food conversion ratio, and survival rate) were collected every 30 days during 90 days of rearing period. Water quality variables (temperature, pH, and dissolved oxygen) were observed during experiment. The results showed that the optimal stocking density for the growth of barb was 10 fish/m3. Best value of food conversion ratio was found 10 fish/m3 compared with 15 and 20 fish/m3 (P<0.05). Meanwhile, there were no significant differences on survival rate between treatments. These results also showed the potential of rearing barb on culture ponds with appropriate stocking density.
