Knowing that this is a global figure, the findings are stark, said Nick Dulvy, a biologist at the Simon Fraser University and a co-author of the study. Sharks are also particularly vulnerable to over-exploitation due to their low population growth rates and long generation times in some shark species it can take several years, even decades between the birth of an individual and the birth of its first offspring. However, white sharks are migratory and this group journeys through the Pacific waters betweenBajaandHawaiiand more inland as far north asWashington state. The main cause is overfishing, which has put three-quarters of these species at risk of extinction. They argued that immediate action is needed to prevent collapses in shark and ray populations.
