Embodiment Construction

[0012] After the seedlings are released in early spring, because the temperature is still low, sometimes it will be cold in late spring, and the single-celled algae in the water will reproduce slowly. It is very easy to breed Enteromorpha, and it is not suitable to blindly fertilize at this time. When the water temperature is basically stable above 10°C, introduce new water rich in algae in time (generally 20 cm, after introducing algae water, the color of the water can be seen in the pond. Yes), use high-efficiency bio-fertilizer water (mainly composed of NPKSi and various trace elements, add specially fermented organic fertilizer, and match with biologically active bacteria), so that single-cell algae can multiply rapidly, reduce the transparency of the pool water, and prevent direct sunlight Entering the beach surface can effectively control the massive growth of Enteromorpha on the beach surface.

Abstract

The invention belongs to the technical field of aquiculture, particularly relates to culturing management for the poly-culture of shrimps, crabs and shellfish in sea, mudflat and ponds and aims to reduce the generation and discharge of aquiculture waste in the culturing process. The culturing management method is characterized by comprising the following steps of: after culturing seedlings in early spring, transferring water to control mass breeding of enteromorpha and delaying the enteromorpha salvaging time to late spring and early summer so as to reduce the generation of enteromorpha waste and increase the seedling protection rate and the survival rate; in summer, changing the bottom and transferring the water, so that the water is not changed, the discharge of culturing wastewater is reduced and the morbidity is reduced; and mixing composite vitamins or an EM preparation into the feed so as to improve the feed conversion rate, reduce the residual feed and the discharged waste, enhance the physique of the cultured animals and improve the survival rate. The method can effectively reduce the substance and energy waste in the poly-culture ecosystem of the shrimps, crabs and shellfish, reduce the eutrophication pollution in the water areas around the culturing area and overcome the problems of blind fertilization, environmental pollution caused by excessive discharge and irrigation and frequent disease outbreak of the traditional culturing management.

Description

1. Technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to the cultivation management of mixed cultivation of shrimp, crab and shellfish in ponds surrounded by tidal flats 2. Background technology [0002] my country is a big aquaculture country, and its aquaculture production accounts for about 70% of the world's total aquaculture production. But my country is not a strong country in aquaculture. While the production of aquaculture is increasing rapidly, the quality of aquaculture products needs to be improved urgently, and the aquaculture ecology needs to be protected. This is mainly related to the low level of aquaculture production management in my country. my country's aquaculture production has fallen into high-density breeding. , frequent disease, large drainage and irrigation, drug residues, environmental pollution, food safety hazards and a series of vicious circles. How to maintain the sustainable and healthy...
