Ommastrephid squid spawning in the North Sea: oceanography, climate change and species range expansion

open access: yesScientia Marina, 2021
The lesser flying squid (Todaropsis eblanae) and the shortfin squid (Illex coindetii) are two abundant ommastrephids of the northeast Atlantic. Spawning ground existence was inferred from the captures of mature, mated females in summer 2016–2019 and ...

Annual trends in catchability and fish stock assessments

open access: yesScientia Marina, 2003
A key assumption of many fish stock assessment models is that catchability is constant over time. We assume here that trends in catchability may occur through fishing power creeping. The tuning fleets, which are prone to fishing power development, may be
