Method for automatic ecological breeding shad

Abstract

The invention provides a method for automatically ecological culture of hilsa herring. The method includes building a farm, to be specific, building a stereoscopic farm; building a circulating water culture system in the bottom layer; arranging a culture wastewater purifying ecological ditch, a wastewater settling tank and a purifying tank at the bottom layer; feeding hilsa herring, to be specific, feeding hilsa herring with plankton cultured on the top layer by the feeding proportion which is controlled according to breeding date and temperature of culture water source; carrying out daily management, to be specific, injecting fresh water and aerating at the reasonable time; carrying out disease control. Since the stereoscopic farm is built, the plankton for feeding hilsa herring is bred together with hilsa herring, eco-environment protection is achieved while culture efficiency is improved; the circulating water culture system recycles the culture water source, metabolite of hilsa herring, carried to the plankton culture layer by the circulating water culture system, is decomposed to provide nutrition for growth of the plankton, and thus, culture cost is reduced; further, the arrangement of a thermal insulation system guarantees precise control on temperature of hilsa herring culture environment.

Description

technical field [0001] The invention relates to the technical field of aquaculture. More specifically, the present invention relates to an automatic ecological method for cultivating shad with the characteristics of high efficiency and low cost for cultivating precious fish. Background technique [0002] The meat of shad is sweet and flat, and it belongs to the spleen and stomach meridian. It can warm the middle and appetize, nourish the fatigue, strengthen and nourish, warm the middle and replenish qi, warm the middle and nourish the deficiency, appetize and refresh the spleen, clear away heat and detoxify, and treat sores. It is advisable to eat with steamed scales. After the shad is steamed, the oil shed from it can be used to smear the burnt area. The shad meat is tender and delicious, fatty under the scales, high in fat, rich in unsaturated fatty acids, has the effect of lowering cholesterol, and is beneficial to prevent vascular sclerosis, high blood pressure and coro...

Problems solved by technology

Many shad breeding methods can not well control the temperature of the water body in the breeding pond, and the accidents of shad army annihilation caused by improper temperature control are not uncommon, which has caused huge economic losses to the breeders; The aquaculture wastewater is directly discharged to the water system adjacent to the farm, polluting the environment; discharged to the internal ditch system of the farm, polluting the aquaculture water, poor water quality management conditions, resulting in a large number of shad deaths
