The impact of demersal Danish seine prohibition on marine fisheries production in Pemalang Regency, Indonesia

Abstract

‘Cantrang’ (demersal Danish seine) is the second largest contributor to the production of marine fisheries in Pemalang Regency. In 2018, the production of demersal Danish seine in Pemalang Regency was 5,353 tons. Marine fisheries practices in Pemalang Regency are multigears fisheries. The use of demersal Danish seine is considered by some stakeholders to be non-environmentally friendly. In 2015, the Indonesian government issued regulations on the prohibition of demersal Danish seine. These regulations created a national level debate, both pro and contra. Then, the regulations were postponed for certain regions (including in Pemalang Regency). The purpose of this research was to estimate the impact of demersal Danish seine ban on the marine fisheries production of Pemalang Regency. This research used a modified Schaefer model. We used the data of production and fisheries efforts (trips) from 2014 to 2018. The results of research showed that the ban on demersal Danish seine can increase the production of other fishing gears that is affected by the demersal Danish seine operation. It was estimated that the average additional production in 2014 to 2018 was 24,889 tons year-1 if demersal Danish seine was not used.
