Özet:

 

Gillnets and net pots are made of synthetic fiber as polyester (PE) and polyamide (PA). These are often lost by heavy  weather or trawling of the active fishing gears. Lost gears result in the ghost fishing because these are non-degradable in  seawater and damage to spawning grounds or habitats. To address these problems, biodegradable nets composed of aliphatic  polyester were developed. This study describes four types of biodegradable net pots for capturing Octopus minor in Southern  Korea, which is an area associated with high rates of net pot loss. The fishing performance of the biodegradable pots was  compared to that of commercial net pots. The net pot with a synthetic body and biodegradable funnel (PE/Bio) produced  approximately 50% of the catch collected using a commercial net pot (PE/PA). Conversely, net pots with a biodegradable  body and a synthetic funnel (Bio/PA) produced the same amount of catch as the commercial net pot. The completely  biodegradable net pot (Bio/Bio) caught 60% of that using the commercial net pot. These findings suggest that net pots  consisting of a biodegradable body and PA funnel may be effective in capturing Octopus minor. Partially biodegradable net  pots (Bio/PA) are as effective as commercial net pots, yet uniquely allows a method of capturing Octopus minor without  affecting the marine environment. 	 	 		 .
