Abstract: Length-weight relationship (LWR), condition factor and biology of six edible fish species were estimated seasonally from July 2011 to March 2012 at Bay of Bengal, Chandipur-on-Sea. A total of 720 specimens were measured and gut contents were also identified during the study period. The result showed that ‘b’ and r

The decreased K factor % was observed in monsoon only (2.68, 2.08, 1.32, 2.73, 1.49 and 1.48 respectively) indicating a strong association between length - weight and six specimen specified allometric growth pattern. Analysis of food items in different seasons showed that the diatoms were the major portion of food item in
