Seasonal variation in length–weight relationship and relative condition factor of Sardinella melanura of Balochistan coast
For length-weight relationship (LWR) and condition factor (K) analysis,the fish Sardinella melanura (Sardine) were caught through gill net from the coast ofGwadar Balochistan during the months of August, 2003 to August, 2006. The studyreveals that the coefficient of determination r2 was ≥ 0.911. The regression slop b valuesfalls within the range of 2.5 - 3.5 and mean value of b was 2.79. The length of 20.6±1.41cm was recorded in post south west monsoon which was the highest and the lowest of13.2±0.63 cm was in pre south west monsoon. The weight of 72.7±26.40gms wasrecorded in post south west monsoon which was highest and the lowest of 20.4±4.5 wasrecorded in pre south west monsoon. The condition factor (K) of 0.90±0.21 was recordedin south west monsoon which was highest and the lowest of 0.80±0.11 was recorded innorth east monsoon. The relationships between condition factor and log weight, andcondition factor and total length were highly significant.
