Abundance and distribution of the Panama brief squid, Lolliguncula panamensis (Teuthida: Loliginidae), in the Gulf of California
This study examines the abundance and distribution of Panama brief squid ( Lolliguncula panamensis ) caught during 15 fishery surveys in the Gulf of California in 2003–2006 and 2008. A total of 2460 individuals were captured in 66 positive squid trawls. Based on the seasonal sea surface temperature...

| Sumario: | This study examines the abundance and distribution of Panama brief squid ( Lolliguncula panamensis ) caught during 15 fishery surveys in the Gulf of California in 2003–2006 and 2008. A total of 2460 individuals were captured in 66 positive squid trawls. Based on the seasonal sea surface temperature pattern, ca ptured individuals were grou ped into two periods: cold (<22 ºC: December, January, F ebruary, March, and April 2003–2006 and 2008) and warm ( ≥ 22 ºC: May, June, July, August, Septem ber, October, and November 2003–2006 and 2008). During the cold period, 1579 organism s were sampled, and during the warm period, 881. Abundance by sex showed that femal es were more abundant during both periods (62% cold, 57% warm) than males (17% cold, 12% warm). During both periods, females (99.6% col d, 91.0% warm) as well as males (99. 3% cold, 95.3% warm) presented re productive activity (maturing a nd mature stages), and they we re captured at depths between 7 and 40 m. Th e highest abundances occurred in diurnal trawls at an average depth of 40 m during the cold per iod and 24 m during the warm period. |
