Flounder Fishing with Russ Alan and Al Ivany (DEP Podcast)

Reducing discard mortality is crucial. The Division of Fish and Wildlife encourages anglers to follow these techniques:

  • Plan ahead - Expect to release fish and have the necessary equipment to do so, including de-hookers and nets; more experienced anglers may also consider using a recompression tool, a device that allows fish to be returned to the water at a safer depth.

  • Use appropriate gear - Use gear suited to the size of the fish that you are trying to catch; 5/0 to 7/0 size hooks are recommended to successfully land bigger fish and reduce discards.

  • Handle fish carefully - Use knotless, rubberized landing nets and rubberized gloves to avoid removing the protective slime layer on fish and help ensure survival when placed back in the water.

Fishing with barbless hooks, or hooks where the barb is crimped, makes releasing a short fish easier and faster which reduces discard mortality. It does require keeping a taut line to not lose a fish, but fish can sometimes be released simply by letting the line go slack, ensuring the fish is unharmed to be caught again.

The following sites and videos provide information on reducing the mortality of released fish:
