Practice responsible recreation: Use best methods for catch-and-release fishing
Strategy:
Practice Careful Catch and Release
Increases in temperature due to climate change have a wide range of effects on coastal fish 3. Each species of fish can only tolerate a certain window of conditions 4,5, and many fish populations in New England have declined in part due to stress from warming ocean temperatures 2.
Fishing also causes stress in fish, primarily through the buildup of lactic acid. Fighting a fish as it is being reeled in by hook and line or other fishing gear for long periods of time, particular in warm waters, can increase stress.
Many fish are unlawful to keep due to management initiatives used to protect populations from overfishing. As such, many fish must be released after being caught by recreational and commercial fishing. Many techniques exist to increase the chances of survival of fish after they are caught (e.g. by hook and line) and released.
The direct and indirect combined effects of fishing and climate change will have compounding and uncertain impacts on coastal fish. Therefore, it is important to maximize the survival of fish that are being released in order to help sustain healthy stocks.
Although many future environmental changes may be difficult to control, there are direct actions we can take to reduce the impacts of fishing on coastal fish.
Action
Use best practices for catch-and-release fishing
Plan ahead
- Discuss handling and release scenarios prior to trip
- Know the regulations and guidelines from resource agencies when harvesting fish or shellfish
- Organize appropriate gear before the fishing trip
Use proper fishing gear
- Have proper equipment to remove hooks (needle nose pliers, hemostat, or hook remover)
- Use corrodible, non stainless steel hooks so that hooks dissolve in water over time if they are left in the fish’s mouth
- Use circle hooks to decrease likelihood of swallowing hook
- If you plan for catch and release, flatten barbs
- Use appropriate size tackle
Use proper handling techniques
- Bring in fish quickly to reduce exhaustion
- If you are not using circle hooks, set hook immediately to prevent fish from swallowing hook
- Leave fish in the water if possible, even for photos
- Measure fish in water if you can
- Wet your hands when handling fish to reduce the removal of protective mucus
- Avoid squeezing fish
- Using a handling net may reduce the amount of time needed to land a fish, reduce injury and stress to fish
Release and revive
- If fish swallows hook, cut the line. Do not try to remove the hook if the fish swallowed it
- If fish appears exhausted and does not freely swim away, you can orient the fish to where it is facing upstream to circulate water through the gills
- Avoid releasing early, hold the fish until it swims away freely
