Study results suggest anatomical hooking location is a major factor influencing spotted seatrout mortality. Fish hooked in the gills and esophagus had mortality rates of 75% and 95%, respectively, whereas fish hooked external and in the mouth had mortalityrates of 8% and 10%, respectively. A significant relationship was found between season and catch-and-release mortality of spotted seatrout with higher mortality rates in spring and summer months than fall and winter. Trends were observed when examining monthly mortality rates and environmental conditions. These trends showed significant relationships with water temperature, dissolved oxygen, and salinity.
Overall tournament mortality was 23% with initial and delayed mortality rates of 11% and 14%,respectively. To assess delayed long-term tournament survival, fish were maintained in a laboratory holding facility for up to 30 days These results reveal a high percentage-greater than 80 percent of tournament caught fish survive post-release.
