A review of interaction between neon flying squid (Ommastrephes bartramii) and oceanographic variability in the North Pacific Ocean

Abstract

The neon flying squid (Ommastrephes bartramii) is a short-lived opportunistic species widely distributed in subtropical and temperate waters in the North Pacific Ocean. The life cycle of O. bartramii from planktonic eggs to nektonic adults is closely linked to oceanographic conditions. The fluctuations in O. bartramii abundance and distribution tend to increase and widen continuously due to the heavy influences of ocean-climate events on various spatio-temporal scales. In this study, we reviewed the interaction between O. bartramii and oceanography variability in the North Pacific with respect to large-scale climatic-oceanic phenomena including El Niño, La Niña, Kuroshio, Oyashio and Pacific Decadal Oscillation (PDO), as well as regional environmental variables such as sea surface temperature (SST), sea surface height (SSH), sea surface salinity (SSS), chlorophyll-a (Chl-a) concentration, and plankton density. The population dynamics of O. bartramii is mediated mainly by meso-and large-scale climatic-oceanic events (e.g., Kuroshio and Oyashio Currents) rather than other local environmental conditions (e.g., SST and Chl-a concentration), because all of the oceanographic influences are imposed on the context of large-scale climate changes (e.g., PDO). An unstructured-grid finitevolume coastal ocean model coupled with an individual-based model is proposed to simulate relevant physical-biological oceanographic processes for identifying ocean-climate influence and predicting O. bartramii distribution and abundance in the North Pacific. Future research needs to be focused on improving the knowledge about early life history of O. bartramii and evaluating the relationship between marine physical environment and two separate passive drifting life stages of O. bartramii including free-floating eggs and planktonic paralarvae.

Climate-related changes in seasonal habitat pattern of Sthenoteuthis oualaniensis in the South China Sea

“…Squid usually preferred to inhabit in the areas with favorable environmental conditions. Once the environments surrounding the original habitat became unsuitable, squids would move to another more suitable habitat (Yu et al, 2015). Therefore, the southeastward shift of favorable environments for S. oualaniensis from spring to autumn determined the similar movement pattern of suitable habitat.…”

“…The abundance and spatial distribution of Ommastrephid squids are strongly influenced by large-scale climate variability and regional environmental conditions (Anderson and Rodhouse, 2001;Yu et al, 2015). Various anomalous climatic events occur will quickly induce the changes of local environments on the fishing and spawning grounds of squid species, leading to the spatial shifts of breeding and feeding habitats and abundance variability (Cao et al, 2009;Postuma and Gasalla, 2010).…”

Response of Abundance and Distribution of Humboldt Squid (Dosidicus gigas) to Short-Lived Eddies in the Eastern Equatorial Pacific Ocean From April to June 2017

“…According to the movement patterns, the life cycle for shortlived squid species is divided into two stages: passive drifting and active migrating stages (Yu et al, 2015). The process by which eddy influences the distribution pattern of D. gigas in the equator can also be divided into two stages.…”

Environmental influence on life-history traits in male squid Uroteuthis edulis with alternative reproductive tactics

“…Considerable flexibility in squid life-history traits (LHTs) has been assumed to be one of the pivotal factors contributing to the increase of squid stocks worldwide, which appears to be a result of the ability of squids to adapt successfully to environmental changes (Pecl et al 2004;Pecl and Jackson 2005;Hoving et al 2013;Doubleday et al 2016). There is great variability in LHTs in a wide range of squid species (Pierce et al 2005;Ichii et al 2009;Ching et al 2019), which is considered to be a mixture of intrinsic variability and the influence of environmental factors, especially water temperature and food availability (Vidal et al 2002;Pecl and Jackson 2005;Pierce et al 2008;Yu et al 2015). Significant differences in growth and size-at-maturity have been observed in different geographical and seasonal cohorts for various squid species (Arkhipkin et al 2000;Jackson and Moltschaniwskyj 2002;Jackson et al 2003;Ceriola and Jackson 2010).…”
