Dosidicus gigas
SPECIES NAME(s)
Jumbo flying squid
COMMON NAMES
Humboldt squid, jibia, pota, calamar rojo, calamar gigante
Jumbo flying squid in the Eastern Pacific extends from the Chilean waters to the Canadian coasts. The NE Pacific and SE Pacific represent genetically different stocks with some migration among them, in a genetic structure apparently influenced by oceanic currents (Sandoval-Castellanos et al. 2010).
In the SE Pacific, different groups have been identified based on size-at-maturity (Nigmatullin et al. 2001).
The latest genetic studies conducted by Chile and Korea were consistent in identifying a single genetic stock that extends on the High Seas, outside national waters, and Peruvian, Ecuadorian, and Chilean national waters (Ibañez et al. 2022)(NIFS 2022). A study by Peru identified some structure but it was argued that this was a result of a different sampling design (Sotil and Guarnizo 2022) (SPRFMO 2022).
ANALYSIS
- There have been significant efforts to increase knowledge about the stock's dynamics and to develop the regional stock assessment model, and increase the data used. Efforts have been initiated in 2017 and continued in 2018, 2019, 2021 and 2022.
- The SPRFMO Commission has achieved agreement among the state members and approved a management measure including several management regulations that entered into force in January 2021, including an observer monitoring program, the use of VMS devices, and improvement in reporting by the member countries.
