文摘
- •
A size-structured model is used to explore the dynamics of a marine fish community.
- •
The large fish indicator (LFI) is the proportion of fish over 40 cm in length.
- •
The model reproduces large changes in the observed LFI in the North Sea.
- •
The results show that the North Sea LFI is driven mainly by cod fishing mortality.
- •
Sustainable fishing on cod will allow the recovery LFI in under a decade.
