Abundancia y distribución del calamar dedal, Lolliguncula panamensis (Teuthida: Loliginidae), en el golfo de 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 pattern, captured individuals were grouped into two periods: cold (<22 °c: december, january, february, march, and april 2003-2006 and 2008) and warm (≥ 22 °c: may, june, july, august, september, october, and november 2003-2006 and 2008). during the cold period, 1579 organisms were sampled, and during the warm period, 881. abundance by sex showed that females were more abundant during both periods (62% cold, 57% warm) than males (17% cold, 12% warm). during both periods, females (99.6% cold, 91.0% warm) as well as males (99.3% cold, 95.3% warm) presented reproductive activity (maturing and mature stages), and they were captured at depths between 7 and 40 m. the highest abundances occurred in diurnal trawls at an average depth of 40 m during the cold period and 24 m during the warm period.
