Title: LENGTH WEIGHT RELATIONSHIP AND CONDITION FACTOR OF LIZA MACROLEPIS (SMITH, 1946) IN CHILIKA LAGOON, ODISHA, INDIA
Abstract:A total of 440 fish specimens were collected from a rtisanal fishers from two fish landing centres i.e., Kalupadaghat and Balugaon of the lago on during pre-monsoon (February & March), monsoon (July &...A total of 440 fish specimens were collected from a rtisanal fishers from two fish landing centres i.e., Kalupadaghat and Balugaon of the lago on during pre-monsoon (February & March), monsoon (July & August) and post-monsoon (November & December) seasons of 2009. Sampling was done once during first week of t he months and the specimens were transported to research laboratory in the polythene bags where total length (TL) and body weight (BW) was recorded. The relationship between the length (TL) and weight (BW) of fish was expressed by equation, W=aL b . The values obtained from LWR showed that the values were isometric in all the season. During all season s, growth co-efficient (b value) was observed to be very nearer to 3 which proves an ide al condition for the species. However, the ‘b’ value was recorded higher during pre-monsoon seasons and gradually decreases. The Condition factor (K) of the experimental fish was e stimated from the relationship, K =100W/L b . Highest condition factor (0.7±0.01) was recorded during post-monsoon followed by monsoon (0.69±0.01) and the lowest (0.66±0.01) during post-monsoon seasons. The mean condition factor was registered as 0.7±0.01 in all the seasons of unsexed specimens.Read More
