To find this information, I recommend contacting:
* The International Union for Conservation of Nature (IUCN): They track the status of endangered species, including sea turtles, and may have data on historical hunting levels.
* The Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES): They regulate international trade in endangered species, including sea turtles, and may have data on hunting and trade.
* National and regional wildlife agencies: The agencies in the regions where sea turtles are found may have specific data on historical hunting levels.
Remember that sea turtle populations are vulnerable and hunting is a significant threat. By seeking out accurate information and supporting conservation efforts, you can help protect these amazing creatures.
