A new study has found that improved fisheries management and conservation measures are turning the tide on shark and ray population declines in the…
The results show how well-enforced governance coupled with science-based fishing limits can help aquatic life recover, concluded the study published last week in the journal Proceedings of the National Academy of Sciences.Sign up to receive daily headline news from Ottawa Citizen, a division of Postmedia Network Inc.By clicking on the sign up button you consent to receive the above newsletter from Postmedia Network Inc.
Before the 1990s, the study said, commercial and recreational fishers were encouraged to fish for sharks, resulting in severe depletion of some large coastal sharks. Co-author John Carlson said regulation of catch limits, bans on harvesting certain species and enforcement of the rules will help populations rebound.
Different species of sharks vary in their life histories and timing of reproduction, making it difficult to manage populations, he noted. While shark populations have seen an increase along the northwest Atlantic, they still face dangers of overfishing in global waters, said the study.
