Percentage contribution of food items to the diet of various size groups of male and female Cynoglossus 

 arel caught commercially off Porto Novo, India, October 1981-September 1982. Male-1 {n 132) and 

 Female-1 (» 111) = size group 95-184 mm TL; Male-2 (n 338) and Female-2 {n 229) = 185-229mmTL; 

 Male-3 (n 136) and Female-3 (n 182) = 230-274mmTL; lVIale-4 (n 21) = 275-364 mm TL; and Female-4 

 {n 47) = 275-454 mm TL. Only values >5% IRI are individually shown; values <5% IRI are clumped 

 together into a single category, the unshaded wedge of the pie chart. PO = polychaetes, PR = prawns, 

 CF = crustacean fragments, FS = fish scales, MI = miscellaneous.
