Project title:
Development of biodegradable materials to reduce the effect of ghost fishing in the Norwegian deep-sea gillnet fisheries.
Duration:
2016 – 2018
Project objectives:
The main objective is to introduce biodegradable gillnets in the Norwegian gillnet fishery for Greenland halibut, cod, saithe and monkfish. This is a responsible fisheries management incentive to reduce the impact of ghost fishing and pollution of plastics in the environment.
Secondary objectives are:
- Define the adequate biodegradation speed of PBS gillnets to suit target fisheries in Norway.
- Adapt the material composition of biodegradable monofilament to biological, physical and oceanographic conditions of the identified target gillnet fisheries.
- Adjust the biodegradation speed of PBS monofilaments at a molecular level to suit the requirements of the identified target fisheries.
- Study physical properties (flexibility, elongation, breaking strength, biodegradation speed), of adjusted biodegradable mono- and multi-monofilament in controlled conditions.
- Asses the fishing efficiency and catch quality of biodegradable gillnets vs those made of nylon.
