There is biodegradable fishing net that fishermen like.
- Even if fishing net is lost, it is expected to have a significant effect on preventing ghost fishing -
National Institute of Fisheries Science (NIFS, Director Choi Wan-hyun) said it has developed high-quality
biodegradable fishing net that has greatly improved strength, flexibility and fishing performance compared to existing biodegradable fishing net to reduce ghost fishing* and protect marine ecosystem.
* Ghost fishing : A common fishing net is made of nylon and other fibers that do not rot well after a long time, so if fishing net is lost during fishing,
fish will be caught in abandoned fishing net, and another predator trying to eat it will be caught and killed again.
Unlike nylon fishing net, biodegradable fishing net is decomposed into water and carbon dioxide
by microorganisms after a certain amount of time in the ocean, which has advantages in reducing damage
to fishery resources and preventing marine pollution.
NIFS succeeded in developing biodegradable fishing net made of PBS* raw materials in 2005 firstly in the world,
and has been distributing various fishing nets to site since 2007, starting with snow crab fishing net.
*PBS (polybutylene succinate): biodegradable netting material produced and used from the past
However, fishing net made from PBS was usually suitable for snow crab fishing, but it was less flexible
than nylon net, which caused some of fishing performance to fall short when used in other species,
and only about 90% of nylon net, often causing them to tear during fishing.
Due to these problems, biodegradable fishing net has been difficult to supply to fishing site despite
the advantages of protecting fishery resources and preventing marine pollution.
In order to improve these problems, NIFS developed new raw material (PBEAS*) early in this year along
with ANKOR Bioplastics, Inha University's Industry-Academic Cooperation Group,
and Jeju Offshore Net Fishing-boat State council.
*PBEAS (polybutylene succinate co-butylene adipate co-ethylene succinate co-ethylene adipate): high quality biodegradable netting material developed in 2020
Using fishing net made of raw material developed, fishing test for yellow corvina and blue crabs
with fishermen showed superior fishing performance and equivalent to nylon net.
The newly developed biodegradable net has improved its strength by 10% and its flexibility by 20%
compared to existing biodegradable net.
Accordingly, NIFS will cooperate with fishing net producers to distribute newly developed net to fishing site
as early as next year.
Distribution of biodegradable net, which had been sluggish, is expected to expand because problem
of strength and fishing performance of fishing net, which had hindered the supply, has been resolved.
Choi Wan-hyun, director of NIFS, said "As newly developed biodegradable fishing net focuses on complaints of fishermen who used biodegradable net at fishing site, government's innovation
through public-private cooperation is expected to increase the effect of protecting fisheries and marine ecosystem."
