The Impact of Stocking Density on Water Quality, Survival and Growth Performance of Free-Swimming Larvae of Goldfish, Carassius auratus (Linnaeus, 1758) in an Indoor Biofloc System
A 30-day experiment was conducted to assess the influence of varying stocking densities (2, 4, 6 and 8 larvae L−1) on the growth performance and survival of free-swimming larvae of Carassius auratus, commonly known as goldfish, within an indoor biofloc system. The larvae (7.05 ± 0.02 mm in length and 1.40 ± 0.00 mg in weight) were stocked in circular tanks wherein a volume of 50 L of water was maintained and provided with vigorous aeration. The experiment used a completely randomised design with five replicates for each density group. A diet comprising a 1:1 mixture of powdered groundnut oil cake and rice bran (RB) was provided as feed. The RB was added daily as a carbon source to maintain the C/N ratio at 20:1. The highest % length gain (209.46 ± 1.47), % weight gain (14028 ± 99.65), specific growth rate (SGR) (16.50 ± 0.02), survival (85.00% ± 1.00) and the lowest apparent feed conversion ratio (AFCR) (1.84 ± 0.01) were recorded in the density group of 2 larvae L−1 (p < 0.05) as compared to other density groups. The results indicated a better stocking density of 2 larvae L−1 for growing free-swimming larvae of goldfish for 30 days.
期刊介绍：
International in perspective, Aquaculture Research is published 12 times a year and specifically addresses research and reference needs of all working and studying within the many varied areas of aquaculture. The Journal regularly publishes papers on applied or scientific research relevant to freshwater, brackish, and marine aquaculture. It covers all aquatic organisms, floristic and faunistic, related directly or indirectly to human consumption. The journal also includes review articles, short communications and technical papers. Young scientists are particularly encouraged to submit short communications based on their own research.
