The 1999 DNR Circle Hook Study

By DNR Fisheries Service Biologist

Rudy Lukacovic

In the summer and autumn of 1999, DNR's Fisheries Service conducted a detailed survey to compare mortality rates of striped bass caught on circle hooks vs. standard "J" bait hooks while chumming for striped bass. Led by principal investigator Rudy Lukacovic, the study sought to quantify the rate of deep hooking with each type of hook, and the corresponding mortality associated with their use. Preliminary work done in 1998 suggested there would be a significant reduction in chumming mortality if circle hooks were used. The results of the more detailed study conducted in 1999 validated these results. Numerous studies involving a variety of different fish species from bluefin tuna to halibut have shown the benefits of using circle hooks, but until now, no one has been able to show such dramatic results for striped bass. Continue on to see the final results of the 1999 DNR Circle Hook Study, and what will certainly be one of this year's most talked about issues.
