Small-waterplane high-density semi-flowing cultivating technology of paddlefish

Abstract

The invention relates to a small-waterplane high-density semi-flowing cultivating technology of paddlefish, 5 to 6 paddlefish fries are put in per cubic meter and matched with 60 chub fries and 100 crucian fries, sweet wormwood herb is put into a fishpond at the front stage so as to cultivate plankton in the fishpond as main fry feed, expanded feed is then put into the fishpond as main feed of the paddlefish at the later period, and fishpond water is replaced on time during the cultivation period. The invention is free from the overcritical requirement on a large-waterplane fishpond for cultivating the paddlefish, the paddlefish can be cultivated by a large scale at the area that is short of large-waterplane fishpond, and the paddlefish has high survival ratio, high growth speed and docile temperament and is easy to catch.

Description

technical field [0001] The invention relates to the aquaculture technology, in particular to the high-density semi-flowing water culture technology of the small-water sturgeon. Background technique [0002] Acipenser belongs to Acipenseridae and Acipenseridae. It is native to North America. Acipenser has obvious advantages over other farmed fish: first, it has a wide temperature range, fast growth, wide source of bait, low production cost, and easy to catch. It has high economic value, and the third is that it does not damage the water environment and can also purify water quality. [0003] However, almost all textbooks and Internet materials have put forward the requirement that the water surface of the sturgeon should be at least 5 mu, and well-known domestic fishery experts have all agreed that "the sturgeon is a kind of fish cultured on a large water surface". In the area of ​​the water surface, when cultivating, the cultivators need to expand the large water surface fi...

[0003] However, almost all textbooks and Internet materials have put forward the requirement that the water surface of the sturgeon should be at least 5 mu, and well-known domestic fishery experts have all agreed that "the sturgeon is a kind of fish cultured on a large water surface". In areas on the water surface, when breeding, farmers need to expand large water surface fish ponds, which makes the area occupied and capital investment very huge
