| Abstract | ||
| Growth patern, relationships of length-weight, and condition factors are crucial information in fisheries management, aiding in biomass determination by converting length to weight and comparing species growth across seasons and locations. The purpose of this study was to examine growth, determine the relationship of length-weight, and assess condition factors for the striped eel catfish reared in floating net cage environments. The study spanned four months, from July to November 2023. A total of 450 juvenile stage fish were stocked in floating net cages, with stocking densities of 50 and 100ind./ 2m3, raised in three separate rearing containers. At the end of the experiment, the fish exhibited total lengths and weights ranging from 94.00- 180.00mm and 5.40- 19.20g (50 individuals/2m³), and 90.00- 170.00mm and 5.30- 31.70g (100 individuals/2m³). Across all rearing conditions, the examination of the length-weight relationship revealed a negative allometric development tendency for the striped eel catfish. The equation model for the relationship of total length (TL) and weight (W) in the 50ind./ 2m3 medium is W= 0.10 TL1.86 (r=0.84; R²=0.71), while in the 100ind./ 2m3 medium, it is W= 0.01 TL2.68 (r=0.94; R²=0.89). Condition factors for the striped eel catfish raised at a density of 50ind./ 2m3 indicate better conditions than those raised at a density of 100ind./ 2m3. The study suggests that the striped eel catfish kept in a controlled environment at low density show superior conditions. | ||
