The length- weight relationship and condition factor of Indian major carp Labeo rohita (Hamilton 1822) under culture conditions

Abstract

Study was conducted for 120 days to observe the efficacy of different doses of spent wash as fertilizer on growth of Labeo rohita fingerlings in terms of length-weight relationship and condition factor. Six experimental treatments (T1 to T5) were prepared by using different dosage of distillery waste- spent wash and T6 was raw cow dong as fertilizer followed by a control without any fertilizer. Maximum average final body weight (60.20g) and specific growth rate (1.63) were recorded with treatment (T6) having raw cow dong as fertilizer followed by T5 (59.86 and SGR 1.62). The value of exponential ‘b’ and the condition factor ‘K’ was in the range of 2.56 to 2.91 and 1.86 – 2.31 respectively in all treatments indicated robustness or well-being of fish.
