Shark and ray populations have plummeted by as much as 71 per cent globally over the past 50 years with nearly one-third of the animals threatened with extinction
A new study has found that improved fisheries management and conservation measures are turning the tide on shark and ray population declines in the northwestern Atlantic Ocean.
"We try to take a look at the few bright spots we have and to highlight how conservation and management is actually working when implemented," he said. 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.
