| Abstract: | According to the offshore resources and the characteristics of small fishing vessels, the small single trawling net is designed by adopting long wings and large size mesh for its belly part and without cutting rate for the fore part of the net. Compared with pair trawling, it increases the single net production for 40 to 45 per cent and lowers the cost and decreases the labour intensity. It improves the economic efficiency. |
