The impact of two-low cost devices, used in reducing marine mammal bycatch, upon the target catch of drift-net fisheries in Zanzibar, Tanzania

With Louise Hopkins

Bycatch is known to be one of the greatest threats to marine mammal populations, with increasing recognition that small-scale fisheries play a large role in this. The use of bycatch reduction devices is mandatory in many areas of the world for larger vessels; however, challenges such as high cost of these devices prevent them from being adequately utilised by small-scale fisheries. Further challenges arise where fishermen are unwilling to use devices if they are believed to have a detrimental impact upon their catch. The study presented here looks at how two low-cost devices, created from recycled bottles, impact upon the target catch of small-scale drift-net fisheries in Zanzibar, Tanzania
