Abstract	Results of mesh selectivity in gill nets for the capture of mackerel Rastrelliger kanagurta (Cuvier) with nets made of nylon twine 210x1x2, 210x1x3 and 210x2x3 in mesh sizes 40,45,50,55 and 60 mm are discussed in this communication. 50 mm mesh size nets made out of nylon twine 210x1x2 were found optimum for the exploitation of commercially accepted size group with a total length of 190-200 mm. The peak value of gilled girth to mesh perimeter ratio for 50 mm nets was found to be 1.1. Linear regressions were fitted for conversion of length to weight and gilled girth to length. Twine size-mesh size relationship was also worked out. 88% of the mackerel caught and 66.1% of the total catch were obtained from dusk operations.
