Does cantrang trawl fishing become more efficient after the partial trawl ban? a case study of technical efficiency of cantrang fishery in the Java Sea – Indonesia

Cantrang- a modified Danish seine that targets demersal fish and squid in the Java Sea- has been banned partially in all Indonesian waters since 2015. The policy goal was to limit the ecological impact by reducing the number of the fleet. This study compares the technical efficiency (T.E.) of cantra...
