According to the Sacramento Bee, a journal article published in the latest issue of Conservation Biology reveals “significant declines in catch rates” for blue (Prionace glauca), mako (Isurus oxyrinchus), and oceanic whitetip (Carcharhinus longimanus) sharks in North Pacific waters. According to the article, the declines in catch rates indicate heavy fishing of the species. The research also showed a decrease in the average sizes of both oceanic whitetip and silky (Carcharhinus falciformis) sharks.
