Deploy fishing gear at different depths
A controlled study in 2007–2009 on the sea floor in Baja California Sur, Mexico (Peckham et al. 2016) found that reducing the number of buoys attached to bottom-set fishing nets reduced unwanted catch of sea turtles. Reduced-buoy nets caught fewer sea turtles (0.06 turtles/100 m of net/day) compared to standard nets (0.19 turtles/100 m of net/day). Unwanted catch included loggerhead Caretta caretta, green turtle Chelonia mydas and olive ridley turtles Lepidochelys olivacea. Average catch of target fish species was similar in both net types (reduced-buoy: 10; standard: 12 kg/100 m of net/day) although the market value of target fish was lower in reduced-buoy nets ($18/trip) compared to standard nets ($25/trip). Reduced buoy nets (1 buoy/8.5 m net) and standard nets (1 buoy/1.7 m net; both net types were 111–120 m long and 4–6 m high) were deployed in pairs for 21–25 hours at a time during summer 2007 (40 deployments), 2008 (40 deployments) and 2009 (96 deployments). The market value of target catch species was calculated based on the catch composition.
