The impact of ‘cantrang’ (Danish seine) fisheries on gill net fisheries in Tegal coastal area, Indonesia

Abstract

The discourse of ‘cantrang’ (Danish seine) ban has become a national issue in Indonesia, including in Tegal region, both Tegal city and Tegal regency. The gill net fishermen in Tegal region complained about the decline of their production after the number of Danish seine (unit) increased. But the ban of Danish seine was rejected by Danish seine fishermen. This research developed a multi-gears bioeconomic model to estimate an impact of Danish seine effort to gill net production. The model in this research was modified from the Gordon-Schaefer model. Our bioeconomic model can explain the relationship between Danish seine and gill net fisheries. This research showed that Danish seine had a negative and significant impact on gill net fisheries in Tegal region. The Danish seine operation in 2008 to 2016 made an average production loss of gill net around 3 814 tonnes per year.
