Jumbo flying squid
COMMON NAMES
Humboldt squid, jibia, pota, calamar rojo, calamar gigante
Jumbo flying squid in the Eastern Pacific extends from the waters off Chile 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), but no genetic difference has been found between these sub-units (Xu et al. 2017). Recent genetic studies conducted in Chile and Peru, suggested no genetic differences among locations or phenotypes and therefore supporting the existence of a single metapopulation in the SPRFMO Convention Area (which extends on the High Seas, outside national waters) and Peruvian, Ecuadorian and Chilean national waters (Ibáñez 2021)(Sotil and Guarnizo 2021)(SPRFMO 2019).
ANALYSIS
- There have been significant efforts to increase knowledge about the stock's dynamics and to develop the regional stock assessment model and data used. Efforts have been initiated in 2017 and continued in 2018, 2019 and 2021.
- The SPRFMO Commission has achieved agreement among the state members and approved a management measure including several management regulations that entered in force in January 2021, including an observer monitoring program, the use of VMS devices, and improvement in reporting by the member countries.
