In South Korea, enterprising scientists conducted research and development to replace nylon fishing nets with biodegradable fishing nets since 2003.
Since 2004, Korean scientists have developed and tested the Shrimp pot, Octopus pot, Red snow crab trap, Swimming crab trap, Conger eel tubular.
Molded products injected by mixing several kinds of biodegradable polymer. show the same physical properties as polyethylene. In the case of traps, non-degradable nylon gear and biodegradable gear show exactly the same catch rates.
The design of the traps and pots is completely different from country to country. This may be due to the different marine environments in the country and the different sizes and characteristics of fish species. It also differs in the form of fishing by fishermen. So, it is unclear whether the results will necessarily be the same as those of Korea. However, I can confidently recommend biodegradable Trap & Pot based on the most successful experimental results.
The fishing net is completed through a weaving process after monofilament extrusion. As Biodegradable Polymer is a copolymer, the monofilament extrusion process is difficult.
Cooling and Drawing conditions often cannot be optimized with existing facilities.
However, it may be necessary to make several types of fishing net products from the same monofilament. In this case, an alternative would be to supply them in monofilament and to make fishing nets by fishing gear producers with weaving machines.
Usually, monofilament is wound 1kg per bobbin.
Biodegradable ropes are widely used for aquaculture farm. The thickness of the rope also varies. There are also various ways of twisting the rope. It can be made soft or firm depending on the purpose of the rope. Production conditions from 8mm up to 50mm have been prepared, and immediate production is possible according to the order. Usually a white rope is used, but you can choose colors such as green, blue, and brown.
A huge sea desert is forming on the east coast of Korea. There are many reasons for the devastation of the sea. For whatever reason, fish cannot survive in a devastated sea. Maritime institutions have tried to create marine forests to prevent sea devastation. It is to make artificial structures and drop them into the sea to make houses for fish.
A biodegradable multi-rope with kelp seeds was attached to the artificial structure.
The biodegradable rope will slowly break down as the kelp grows and forms the marine forest.
Naturally, kelp will lower its beak on structures and sea floors.
The fact that the sea is being devastated was made known to the public through the media and it was a big shock.
This marine forest was quickly lost in the typhoon, and there seemed to be no results even after several attempts. However, after more than 10 years of efforts, some cases of submarine forest creation have emerged.
As well as supplying fresh oxygen by cultivating mountains and forests on land,
forests in the sea are important national resources that attract fish and enrich fishing resources.
The net was developed as an agricultural vegetation mat and a bird net.
During road construction, reinforcement with net on the incision surface and planting grass and grass to secure road stability. The soil on the incision surface of the road is easy to flow down,
but the construction period is too long to wait until the soil becomes hard,
so use a net to prevent it from flowing down.
Also, knotless net is available. knotless net is a component of pot and trap.
A knotless net is about 25% lighter than a knotting net.
In addition, there is no knot, so it is expected to disassemble evenly.
