Assessing the Effectiveness of Cow Manure and Gypsum Soil Amendments in Mitigating Sodic Soil Conditions and their Influence on the Length-weight Relationship of Labeo rohita

Aquaculture practices in sodic soil conditions pose significant challenges, necessitating the exploration of sustainable and efficient methods to promote fish growth. This study focused on investigating the growth of Labeo rohita fry under sodic soil conditions in circular plastic tanks. The experiment involved seven treatments with varying levels of cow dung and gypsum application, conducted in triplicate sets. Results showed a diverse relationship between length and weight in L. rohita, with regression coefficients ranging from 0.242 to 3.234 across treatments. The findings indicated negative allometric growth for treatments T1 to T6 and the control group, where length increased more rapidly than weight, resulting in a slimmer profile as the fish grew. In contrast, treatment T7 exhibited positive allometric growth, with the highest doses of cow dung and gypsum, suggesting that weight increased more rapidly than length.
