High-yield high-efficiency technology for cultivating sinonovacula constricta in pond

Abstract

The invention discloses a high-yield high-efficiency technology for cultivating sinonovacula constricta in a pond, which is characterized by comprising the steps of (1) pond selection, (2) pond modification, (3) pond treatment, (4) treatment of an algae cultivating pond and (5) selection of sinonovacula constricta larva. By means of modification of the cultivating pond and changing of an existing blind and unsuitable fertilizing-feeding mode, growth speed of sinonovacula constricta cultivating in the pond is greatly improved, a cultivating period is shortened, two-batch yield of the pond sinonovacula constricta in one year is achieved, cultivation survival rate, specification and yield are improved remarkably, and high-quality, high-yield and high-efficiency pond cultivation of the sinonovacula constricta is facilitated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a culture technique for high-yield and high-efficiency ponds of razor clams. Background technique [0002] In recent years, the cultivation of traditional razor clam ponds has resulted in aging ponds, excessive accumulation of organic matter in the ponds, aquaculture water lack of oxygen, and serious water quality deterioration. In addition, due to factors such as blind feeding and improper fertilization methods, the death of razor clams in ponds often occurs. And become more and more serious, cause unit yield is low, and production is unstable, causes serious economic loss to raiser, has restricted the healthy sustainable development of razor clam aquaculture to a large extent. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a high-yield, high-efficiency pond cult...

[0002] In recent years, the cultivation of traditional razor clam ponds has resulted in aging ponds, excessive accumulation of organic matter in the ponds, lack of oxygen in the ponds, and serious deterioration of water quality. Affected by factors such as improper fertilization methods, the death of razor clams in pond culture often occurs, and it is becoming more and more serious, resulting in low yields and unstable production, causing serious economic losses to farmers, and restricting the healthy and sustainable development of razor clam aquaculture to a large extent.
