Extends Life of Target Fishing Areas

trawl-overhead

The Wing Trawling System leaves the sea bed in much better shape than typical otter trawl doors.

A large trawl with otter doors will require a pair of 10 foot doors which equates to 20 feet of trawl door running out ahead of and outside of the actual fishing area. For a twin trawling vessel this area is doubled. As documented by video and photos, the otter trawl door does a good job at creating a huge disturbance of the sea bed.

The footprint for the Wing Trawling System is just 3 feet in comparison to 20 feet for the same trawl using doors.

It’s a well-known fact that the area the trawl door is ran through is affected at sustaining its fishing ability. Either the shrimp will become buried or they will swim away to another area, not to mention the damage the door does to the sea floor. The footprint for the Wing Trawling System is just 3 feet in comparison to 20 feet for the same trawl using doors. There is actually only 2 feet outside the net in comparison to 20 feet on the doors.

By working an area with several vessels pulling the Wing Trawling System there will be cleaner UN-worked bottom sustained over a longer period of time resulting in more production of the targeted catch and less damage to the area.

Trawl Door Coverage of the Seafloor vs Wing Trawling System

Each trawling system has a footprint that extends out beyond the area being fished by the net. This contact with the seafloor disturbs and kills small sea life. This mortality can be added to the by-catch amount captured by the net. This contact does not catch the target fish but is necessary for the operation of the net.

On an average 24 hour period the Trawl door rakes across 280 acres of seafloor. During the same 24 hour period the Wing Trawling System glides across 35 acres of seafloor. If a trawler works 150 days a year it would be a difference of 42,000 acres of coverage to 5,250 acres with the Wing Trawling System. No doubt this will save the fishing area and reduce its wear and tear.
