挪威一家水产研究所研究出一种新型的网格养鱼方法。该法是在水中设置多层网格状养鱼设施,其中心部位有一圆柱体,圆柱体与各层相通,鱼苗和饲料都从该处投放。鱼儿平时到圆柱体内吃食,然后又回到各层网格内自由游动及生长。待鱼长到收获期时,只要将网格向上一提即可把鱼收获起来。 A Norwegian Institute of Fisheries has developed a new method of mesh fish farming. The law is set up in the water multi-grid fish-shaped mesh facilities, the central part of a cylinder, the cylinder connected to the various layers, fry and feed are put from there. Fish usually eat into the cylinder, and then back to the layers of the grid free swimming and growth. When the fish grow to harvest, as long as the grid up mention the fish can be harvested.
