Decadal Changes in the Annual Growth of Two Commercial Ommastrephid Species in the Pacific Ocean

Neon flying squid Ommastrephes bartramii and jumbo Dosidicus gigas are two important commercial ommastrephid species in the Pacific Ocean. As short-lived marine species, squids highly susceptible to changes climate environments. According samples collected from northwest southeast Ocean different years, we explored growth characteristics of these terms their mantle length (ML) distribution relationship between body weight (LWR), also considering relative condition factors (Kn), effects El Niño Southern Oscillation (ENSO) on growth. The results showed that ML for O. D. had significant differences among years sexes (p < 0.01), size females was larger than males. LWR both demonstrated a positive allometric pattern (b > 3), parameters b were influenced by year sex. Furthermore, there Kn interannual fluctuations quite significant. In conclusion, alterations environment caused change impact this study. ENSO events opposite species.
