This pioneering study in Marathwada demonstrates the region’s potential for cage aquaculture. Over the course of 180 days, Clarias batrachus (walking catfish) showed substantial growth in both natural and supplementary feeding cages. In natural feeding conditions, the average weights were: 5.48 ± 1.69 grams during the first month, 6.71 ± 2.17 grams during the second month, 11.60 ± 7.19 grams during the third month, 19.57 ± 12.32 grams during the fourth month, 45.80 ± 17.58 grams during the fifth month, 97.27 ± 24.59 grams at the end of six months.In cages with additional supplemental feed, the average weights recorded were: 7.20 ± 0.84 grams in the first month, 14.05 ± 3.82 grams in the second month, 24.61 ± 4.69 grams in the third month, 51.01 ± 14.12 grams in the fourth month, 91.22 ± 14.11 grams in the fifth month, 156.40 ± 10.85 grams after six months.By the conclusion of the culture period, fish in the supplemented feeding cages reached an average weight of around 156.40 grams, notably higher than the 97.27 grams in natural feeding cages, underscoring the effectiveness of supplemental feeding for promoting growth.
