While there are several species of marine turtles that can be found in Hawai’i , the most common is the honu, or the Hawaiian green sea turtle (Chelonia mydas). Basking, or resting on the beach or at the water surface, is a behavior unique to this species in Hawai’i that is thought to have a thermoregulatory function. The green sea turtles that are found in Hawai’i are currently listed as threatened under the U.S. Endangered Species Act. The good news is that this population is showing some signs of improvement, and nesting is increasing at 3-5% per year. There is a lot that the species still has to contend with in order to be recovered, especially with sea level rise and storms affecting their low-lying nesting grounds: 96% of the population nests at one location, Lalo (French Frigate Shoals) which is located in the Northwestern Hawaiian Islands and part of Papahānaumokuākea Marine National Monument. Other threats to our honu include fisheries interactions, disease, and boat strikes. When turtles and fisheries interact, it is often the line, not the hook, that is most dangerous for the turtle: the line can cause strangulating injuries to the flippers and line ingestion can lead to GI obstruction. Prevention is always best, so if you enjoy fishing, please dispose of your line properly to keep it out of the marine environment and pick up discarded line anytime you see it. NOAA Fisheries’ FAST (Fishing Around Seals and Turtles) guidelines also say that if you accidentally hook a sea turtle, it is okay to reel it in, cut the line as close to the hook as possible, and release the turtle – IF you feel safe doing so.
As veterinarians, you can also help sea turtles by being knowledgeable about what to do if you are contacted or come across wild turtles that are in trouble. First, pause before taking any immediate veterinary action. Dead turtles or those that are entangled, hooked, injured, or appear sick, should be immediately reported to the Hawaiʻi statewide NOAA Marine Wildlife Hotline at (888) 256-9840. Call this number and wait for a return call for further guidance. If you observe illegal activity, such as harassment or illegal fishing/gear, send photos or video (including contact information of the suspected perpetrators) to RespectWildlife@noaa.gov and the Hawaiʻi Department of Land and Natural Resources (the DLNRTip app is a rapid and effective way of filing such reports, or you can contact DLNR at (808) 643-DLNR).
