How To Trawl Classification?
Jan 12, 2018

Trawling is the use of the ship's movement, towing fishing gear in the sea or sea water forward, forcing fishing gear through the waters of fish and crabs and other fishing objects into the cyst, to achieve the purpose of fishing.


Traw Product Category:

Single vessel (double vessel) Large net bottom trawl, single vessel (double vessel) Sparse bottom trawl, single vessel (double vessel) Small net bottom trawl, single vessel (double vessel)


1, single boat (double boat) large net bottom trawl

Mesh size 6 ~ 20 meters, mesh specifications (net mouth circumference tight) 200 ~ 1200 meters. Hand-knit and machine knitting combination, the net has a larger swept the sea area, a smaller energy coefficient, suitable for deep-water operations, fishing for the clustered fish higher efficiency, but requires higher operating skills. According to the differences of fishing targets and operating sea areas, the Company provides two types of trawling: rapid trawling and high-mouth trawling, respectively. The company mainly catches bottom (near-bottom) hardfishes of hairtail, bighead carp, mackerel and seabream. Can also be based on actual customer requirements, on behalf of the configuration of a reasonable trawl.


2, single boat (double boat) sparsely bottom trawl

Mesh size of 1 to 5 meters, mesh specifications (net mouth tight circumference) 200 ~ 500 meters. Hand-knit and machine knitting combined net swept the sea area, energy consumption, although slightly lower than the large mesh trawls, but the operating technology is relatively easy. According to the differences of fishing targets and operating sea areas, the Company provides two types of trawling: rapid trawling and high-mouth trawling, respectively. The company mainly catches bottom (near-bottom) hardfishes of hairtail, bighead carp, mackerel and seabream. Can also be based on actual customer requirements, on behalf of the configuration of a reasonable trawl.


3, single boat (double boat) small net bottom trawl

Mesh size of less than 1 meter, mesh specifications (net mouth circumference tight) 50 ~ 200 meters. Mainly machine-trimmed nets, net structure is simple, easy to operate. The main fishing octopus and other cephalopods, moray, shrimp and so on. According to the actual use of the company requirements, on behalf of the configuration of a reasonable trawl.


4, a single boat (double boat) variable layer (middle table) trawling

Mesh size 8 to 20 meters, mesh specifications (net mouth tight circumference) 400 ~ 1200 meters. Hand-knit and machine knitting combined with net sweeping the sea area, energy efficiency, drag relatively fast. The operation technique is relatively complicated. Major fishing class, mackerel, and other pelagic fish. I plant according to the actual use of customer requirements, on behalf of the configuration of a reasonable trawl.
