Summary | Of 565 individuals of the Mediterranean locust lobster Scyllarides latus from landings on Pico island, Azores, during the summer of 1982, 55 per cent were males and 45 per cent females, of which 75 per cent were ovigerous. The egg-bearing period lasted for approximately 6-8 weeks starting in June. Eggs hatched into naupliosoma stage larvae which lasted 40-60 min. The main diet of S. latus in summer consisted of limpets (Patella sp.). After the results of this study were known, the Secretariat of Agriculture and Fisheries of the Regional Government of the Azores changed the closed season for catching this species from 1 August - 30 April to 1 May - 31 August. A phyllosoma larva stage XI found close to the coast of Pico was calculated to be 11 months old. Tagging carried out intermittently from 1984 to 1990 has not been successful as no recaptures were made. |
