The saltwater hook guide: circle hooks, steel and the Texas rules

Saltwater is hard on hooks, and the fish often get a hook deeper than anglers realize. Texas has rules on circle hooks for some fish, so this is one place where the hook you pick can be the law and not only a preference. This guide covers what a circle hook is, what the research says, what Texas and federal pages require, and how to fish one.

Circle, J and Kahle hooks

South Carolina's Department of Natural Resources quotes the Atlantic States Marine Fisheries Commission in defining a circle hook as a non-offset hook with the point turned perpendicularly back to the shank. An offset circle hook has a point that is not in line with the shank. A J-hook is the traditional hook for natural bait, and SC DNR says you set it by jerking the rod. A Kahle hook looks like a circle hook but the point angles toward the eye, and the gap between point and shank is larger.

What the research says

SC DNR's red drum study found that with J-hooks, 35 to 40 percent of fish were gut-hooked and 5 to 11 percent died within 48 hours. With non-offset circle hooks, 5 to 10 percent were gut-hooked and 2 to 5 percent died from those injuries, and over 90 percent of fish were lip-hooked. Offset circle hooks fell in between, with about 23 percent deep-hooked and mortality of about 10 percent, similar to J-hooks. Those numbers are for red drum on SC DNR's hooks, so they are one study, not a promise for every fish.

The wider 2005 review of 53 release-mortality studies found the same direction: five studies reported lower mortality with circle hooks than J-hooks and two found no difference, and across all estimates J-hooks had significantly higher mortality than circle hooks. The Louisiana Sea Grant newsletter summarizing the Gulf rule says the reduction in release mortality results primarily from the tendency of circle hooks to jaw-hook fish.

Kahle hooks: SC DNR says no research has been done on them, and that they may lead to more gut-hooking and may contribute to a high mortality rate. That is an untested concern, not a finding. If you plan to release a fish, a non-offset circle hook is the choice with evidence behind it.

How to fish a circle hook

A circle hook is designed to slide to the corner of the mouth as the fish moves off, so you do not jerk the rod the way you would with a J-hook. Let the fish take the bait and start to swim, then reel steadily until the rod loads, and lift smoothly. A snap hookset can pull the hook out before it rotates. This is standard technique, in our own words.

What Texas and federal rules say

The federal circle-hook rule began in 2008. The Federal Register notice said non-stainless steel circle hooks are required when fishing with natural baits, and that every vessel needs a dehooking device and a venting tool; the rule has been updated since, so use TPWD's current page, not the 2008 notice. The Louisiana Sea Grant newsletter said the Gulf Council and NOAA selected the hook rules from a long list of options to reduce discard mortality, particularly of undersized red snapper. The usual reason given for requiring non-stainless steel is that a carbon-steel hook left in a fish eventually corrodes away; we did not find that reason stated in the TPWD page, so treat it as the common explanation and not an official finding.
