Bluefish: Welfare in Recreational Fishing and Incidental Capture

Bluefish are aggressive predatory fish subject to intense recreational fisheries along the US Atlantic coast, with welfare considerations in catch-and-release angling and live baitfish markets.

Key Facts

Bluefish are highly aggressive predators found along temperate Atlantic coasts
They are popular recreational fish prized for their fighting ability and speed
Bluefish have sharp teeth that make handling hazardous for both fish and angler
Catch-and-release welfare varies widely depending on handling, water temperature, and exhaustion level
Bluefish populations fluctuate dramatically with multi-year boom and bust cycles

Welfare Considerations

Bluefish welfare in recreational fisheries depends critically on handling practices after capture. The physiological stress of exhaustion from fighting causes lactic acid accumulation and oxygen debt that reduces post-release survival. Air exposure during unhooking and photography compounds stress through desiccation and oxygen deprivation of the gills. The sharp teeth of bluefish mean that unhooking often requires prolonged handling or bite damage to the fish from struggling against restraint. Water temperature affects recovery capacity significantly, with warm summer water reducing oxygen availability and slowing recovery. Research suggests that some proportion of released bluefish, particularly those experiencing extended fights or air exposure, do not survive release.

What You Can Do

Use circle hooks that lodge in the jaw rather than being swallowed, reducing injury and unhooking time
Keep bluefish in the water during unhooking wherever possible
Avoid unnecessary air exposure and return fish promptly, particularly in warm summer water
Learn proper revival techniques for exhausted fish before release
Support angling organizations that promote species-appropriate welfare-based handling practices
Consider the welfare implications of keep quotas and release practices in recreational fishery management
