Selectivity of gill nets for Scomberomorus commersoni
Selectivity of gill nets for S. commersoni was studied with nets made of 4 different mesh sizes fabricated with 4 different specifications of nylon twines. Fishing operations were conducted off Cochin through the fishing seasons 1968-72. The commercially significant size group of S. commersoni was found to fall in the length range of 850-950 mm. The optimum mesh size required for the capture of this group of S. commersoni was estimated as 76 mm. bar in nylon twine 210/12/3. The relationship between the twine size and mesh size was alsoworked out.
