利用湖泊、河道等大型水面养鱼,在养殖学上称为“大水面养鱼”,在江苏称为“外荡养鱼”,是颇具特色的一种养鱼方式,在我国有悠久的历史。江苏省东台市地处苏中平原,东濒黄海,西接里下河水网地区、境内河道纵横,发展河道养鱼的条件十分优越。近几年来东台市通过分段精养、网箱配套、人工投饵、增加鱼种投放等方法,迅速提高了河道养鱼的产量,1986年全市河道养鱼亩产达到40.9公斤,1987年达48.7公斤,其中高产河段达亩产300公斤以上,他们的做法主要有四点: 一、选择适宜河段,实行精养高产。为了达到大面积高产的目标,选择适宜河段实行人工精养增加总产,是有效措施之
The use of lakes, rivers and other large surface water fish, aquaculture known as the “large surface of fish,” in Jiangsu called “outside the fish” is a characteristic of a fish farming in our country has a long history . Dongtai City, Jiangsu Province, is located in the plain of the Soviet Union, east Yellow Sea, west and downstream river network area, the territory of the vertical and horizontal river, the development of fish culture conditions are superior. In recent years, Dongtai City, through segmented intensive training, cages supporting, artificial feeding, increased species feeding and other methods to rapidly raise the river fish production in 1986, the city’s river fish per mu reached 40.9 kilograms in 1987 reached 48.7 kilograms, of which high-yielding reach more than 300 kilograms per mu, their approach has four main points: First, select the appropriate river, the implementation of intensive high-yielding. In order to achieve the goal of large-area high-yielding, it is an effective measure to choose the suitable river to implement artificial densification and increase the total output
