Abstract
AbstractThe settlement of the puerulus stage of the Red Spiny Lobster (Panulirus interruptus) was measured in Bahía Tortugas, Baja California, using artificial collectors of the GuSi type. In the period 1993-1995 monthly sampling during the new moon phase was carried out. Catch rates per collector ranged from 1 to 10 pueruli. Mean catch per site ranged from 0 to 2.52 puerulus/collector/new moon phase. The general settlement pattern showed a conspicuous seasonal cycle where autumn was the dominant season, during spring there was a second minor peak. In both years September and October showed the highest catches, but September 1994 to February 1995 was a longer settlement period with maximum catches. The carapace length varied from 6.5 to 33.5 mm, 7.5 mm being the most frequent size. The season of maximum settlement seems to be related with a maximum sea temperature (20 to 21°C) which in Baja California occurs during the autumn.
