The length-weight relationship and relative condition factor of Asian seabass Lates calcarifer (Bloch) was estimated based on the length and weight data collected from Chilika lagoon during March, 2008- February, 2009. The total length of fishes ranged from 20.0 to 113.70 cm and wet weight of fishes ranged from 500 to 3394.00 g. The length-weight relationship was estimated as W= 0.003 L2.890 and the sizewise relative condition factor (Kn) fluctuated from 0.90 to 1.11. The ‘b’ value indicated that the growth pattern is not isometric even though, the general wellbeing of fish inferred from relative condition factor (Kn) was suitable during the study period. The condition factor may be used to estimate the total weight of fish caught from length-frequency data, thereby eliminating the need for bulk weighing of groups of fish from the lake and, measuring changes in robustness/health of this population relative to past or future samples at the same place and season.Pages: 222-224 | 892 Views 13 DownloadsDownload Full Article:
