Overview
New research has demonstrated the efficacy of two distinct deterrents in mitigating seabird entanglement within fishing nets: a floating scarecrow, developed by U.K.-based scientists, and a repurposed bird-scaring kite. Both devices were observed to contribute to the protection of threatened seabirds from incidental capture in fishing operations.
Research Context
The imperative behind this research stems from the established issue of seabird bycatch, where seabirds become inadvertently caught in fishing gear. Such entanglements pose a significant threat to various seabird populations, particularly those already categorized as threatened.
Approach
The research investigated two specific deterrent devices. The first was a floating scarecrow, conceptualized and developed by scientists based in the United Kingdom. The second involved the adaptation of a commercially available bird-scaring kite, typically employed for different avian deterrence purposes. The study aimed to assess the ability of these devices to prevent seabirds from interacting with fishing nets, thereby reducing bycatch.
Findings
The research indicated that both the floating scarecrow and the repurposed bird-scaring kite can help protect threatened seabirds. Specifically, these devices were found to reduce the incidence of seabirds getting caught in fishing nets.
Why This Matters
The findings are relevant for conservation efforts targeting threatened seabird species, offering potential tools to reduce their mortality rates associated with fishing activities. Mitigating bycatch is crucial for the long-term sustainability of seabird populations affected by fishing operations.
