The barred sand bass Paralabrax nebulifer is a commercially important fish off the west coast of Baja California Sur. To assess the diet of this species and variations as a function of sex and reproductive condition, 60 specimens were captured using traps during seven seasonal sampling trips from August 2016 to August 2018 in an adjacent area to Magdalena Bay, Baja California Sur, Mexico. The stomach contents of 50 specimens were obtained (23 males and 27 females). Sex was diagnosed by direct observation of the gonads. Based on the gonadosomatic index, hepatosomatic index, and histological analyses, the reproductive season of the barred sand bass was corroborated for August 2016, April, August, and September 2017, and August 2018, and the non-reproductive season was corroborated for November 2016 and March 2018. The Index of Relative Importance (IRI) was used to classify the main diet components, which comprised three fish species, seven crustacean species, and one mollusk species. According to the IRI, the South American pilchard Sardinops sagax and the red pelagic crab Pleuroncodes planipes were the prey that contributed the most (55%) to the barred sand bass diet. The ANOSIM showed that there were significant differences in the amount and type of prey consumed by sex; the SIMPER analysis revealed that the species contributing the most to differences between the sexes were S. sagax (16.58%), Euphylax dovii (15.95%), Stenocionops ovata (12%), and P. planipes (11.82%) for females. There were significant differences in the amount and type of prey consumed between types of reproductive season; the species contributing the most to differences between seasons were Anchoa spp. (27.76%), and P. planipes for non-reproductive season (22.67%), and S. sagax (11.08%) for reproductive season. The feeding strategy of the barred sand bass was that of a specialist carnivorous predator that fed mainly on the fish Sardinops sagax during the reproductive season, which supply the dietary nutritional requirements of the lipids HUFA (arachidonic acid, 20:4n-6; eicosapentaenoic acid, 20:5n-3; docosahexaenoic acid, 22:6n-3), nutrients required to achieve reproductive success.

Analysis of the genetic structure of the red spiny lobster (Panulirus interruptus) population was conducted along the Baja California Peninsula, Mexico. Samples for allozyme analysis came from Ensenada, Punta Eugenia, Punta Abreojos, San Juanico, and Bahia Magdalena (about 50 individuals each). Of 16 loci analysed, five were polymorphic (95% criterion) in at least one subpopulation. A significant mean value of FIS = 0.125 indicated some subpopulations departed from Hardy-Weinberg expectations; increased homozygosity was particularly evident for alleles EST-2*b and LAP*a at Ensenada and EST-2*c and EST-4*c at San Juanico. MeanFST = 0.101, which included 99% criterion polymorphic loci, was significant (P < 0.05), supporting a genetic structure throughout the species’ geographical range. Pairwise heterogeneity and FST tests showed no significant differences in allele frequencies between Punta Eugenia and Punta Abreojos, but several pairwise comparisons among the other locations, especially at the most variable loci, showed significant differences, supporting a hypothesis of genetic differentiation of P. interruptus into three subpopulations: southern, central, and northern Baja California. Oceanographic processes, such as semipermanent eddies south of Punta Eugenia that tend to retain phyllosoma larvae, may help generate this pattern. The implications of these findings for the management of the resource are also considered.

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.
