What happens after the catch and release? A UMass study explores the impact on striped bass populations.
Roy Leyva, a renowned angler and world record holder, recalls the days of a moratorium on striped bass fishing in the 1980s due to overfishing. Fast forward to the present, and the species is once again facing a decline in numbers. A recent study at UMass Amherst delves into the effects of catch-and-release practices on striped bass, shedding light on the physiological stress these fish endure when released back into the water.
The study, led by Professor Andy Danylchuk and Grace Casselberry, involved catching 521 striped bass and conducting a series of reflex tests to assess their stress levels. By examining the fish's reactions to tail grabs, swimming attempts, and gill movement, researchers gained valuable insights into the fish's overall well-being. One of the most intriguing findings was the impact of prolonged air exposure on the fish's recovery and survival post-release.
The study revealed that the time spent out of water significantly influenced the fish's ability to recover. By monitoring the fish's post-release swim patterns, researchers observed that longer periods of air exposure made it more challenging for the fish to regain their strength, potentially affecting their chances of survival. This discovery highlights the importance of handling practices for anglers, as it may determine the fish's ability to fight off predators and maintain population stability.
Anglers, like Leyva, play a crucial role in the conservation of striped bass. Danylchuk emphasizes the power of informed advocacy, where anglers' firsthand knowledge and engagement can drive positive change. By sharing data and raising awareness about the effects of air exposure, anglers can contribute to the preservation of striped bass populations and prevent another population crash.
The economic impact of recreational striped bass fishing is substantial, generating billions in annual revenue for the states along the Atlantic Coast. Leyva and the researchers agree that the future of striped bass lies in the hands of the fishing community. It is a call to action for anglers to adopt responsible handling practices and ensure the longevity of this iconic species.
