Why is the use of circle hooks strongly recommended for released white marlin compared to J-hooks?

Answer

The mortality rate for released white marlin caught on J-hooks is significantly higher

From an angler's perspective focusing on conservation and post-release survival, the choice of terminal tackle is critically important when targeting white marlin. Extensive observation and data analysis have shown a substantial difference in the fate of released fish depending on the hook type used during capture. Specifically, when white marlin are caught using traditional J-hooks, the subsequent mortality rate for those individuals released back into the water is documented to be significantly elevated when compared to the outcome for fish captured using circle hooks. This disparity mandates the recommendation that sport anglers strongly favor circle hooks when using natural baits, as this practice yields documented survival benefits for the population upon release.
