Abstract:

Bycatch, the unintended capture of animals in commercial fishing gear, is one of the hottest topics in marine conservation today. About 25% of the entire global catch is by-catch This surprisingly high level of by-catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students will analyze the significance of by-catch in the global ecosystem and propose solutions to help reduce by-catch Students will become familiar with current attempts to reduce fishing mortality of these animals, such as acoustic alarms, breakaway links, gear modification, and time-area closures. Through the associated activity, the problems that managers face today will be reinforced and students will be stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of by-catch
