In the period from November 1990 to March 1992, 1754 squid of the species Loligo forbesi from the Azorean fishery were studied; 58.9 per cent were males (mean size = 590 mm dorsal mantle length), 41.1 per cent females (mean size = 359 mm dorsal mantle length). The squid were captured by jigging and animals less than 200 mm dorsal mantle length were not caught. Of males, 81 per cent were sexually mature, of the females 87.1 per cent, both sexes showing highest maturity in winter and spring, lowest in autumn. Several different maturity indices were applied. No specific recruitment period could be established.
