IGFA Angling Rules Set Standards for Tuna Release and Records

The International Game Fish Association's International Angling Rules and associated release guidelines are the benchmark many tournaments and recreational anglers use for catching, measuring, documenting, and releasing large pelagic species such as tuna. The guidance emphasizes a release-first approach: fish entered for length records should be measured and released so they swim away in good condition whenever possible. That emphasis affects how anglers outfit boats, handle fish at the rail, and document claims for records.

Equipment and landing procedures matter. The rules prohibit the use of gaffs on fish intended for release and recommend landing nets that are knotless and rubberized to protect the fish’s slime coat and scales. Net length is limited for record purposes, so verify any tournament limits before fishing. Have lip-gripping tools on hand and use them carefully to avoid excessive pressure on the jaw and surrounding tissue.

Handling practices are designed to minimize harm. Support fish horizontally rather than suspending them vertically, keep time out of water to a minimum, and avoid touching eyes and gills. Photographs and measurements are required for record claims, so prepare camera and measurement tools in advance to shorten air exposure and handling time. During longer documentation steps, periodically place the fish back in the water or into a live well to reduce stress.

Revival and release procedures are explicit. Revive fish by moving them forward in the water until they regain strong, independent swimming; do not hold fish stationary beside the vessel. These steps improve post-release survival and are part of the protocols that many tournaments adopt to balance competition with conservation.

For anglers aiming at records, the IGFA outlines specific procedures for All-Tackle Length records and catch-and-release record categories. Following those procedures ensures documentation is acceptable and helps maintain a level playing field across events. For everyday anglers, adopting these standards reduces injury to the resource and improves chances that released tuna survive.

Practical takeaways: outfit the boat with a knotless rubberized net and appropriate measurement tools, keep a camera ready, avoid gaffs on release candidates, support fish horizontally, and revive fish by moving them forward in the water until they swim away. These steps protect fish welfare, support credible record claims, and align your fishing with the conventions used by many tournaments and anglers worldwide.
