Composition for reducing stress response of fish cultured in deep and far sea and living body transfer method

Abstract

The invention belongs to the technical field of deep and far sea culture, and discloses a composition for reducing stress response of deep and far sea cultured fishes and a living body transfer method. Before fishes are caught and transported, a composition containing succinic acid, oyster shell powder, polygala tenuifolia micro powder and spina date seed micro powder is added into feed, and the fishes are continuously fed for 5-6 days. Before transportation, vitamin C and vitamin E are respectively added into the culture water body to soak and transfer the fishes. Afterwards, the fishes are transferred into a live fish ship transfer pond, a proper amount of polyhexamethylene guanidine disinfectant is added, the fishes are transferred into a culture net cage or a culture pond through a fish suction pump, feeding is stopped for 1-2 days, after the fishes recover vigor, beta carotene is added into feed, and normal culture can be recovered after continuous feeding is conducted for 4-5 days. The invention establishes a living body transfer method capable of effectively reducing the stress response of the fish cultured in the deep and far sea, and provides important technical support for the healthy development of the fish culture industry in the deep and far sea.

Description

Technical field [0001] The present invention is a far -reaching seas breeding technology, especially a composition that reduces the far -reducing fish stress response and reducing the living body transfer method of far -reaching sea breeding fish stress reactions. Background technique [0002] The far -reaching sea farming is the strategic direction of the development of the sea water breeding industry in my country, and it is also one of the main industrial models for my country's development of marine economy. At this stage, the main varieties of farmers are economic fish. The breeding model is mainly based on large cages and farmers. It has outstanding advantages such as large breeding density, high benefits, small environmental hazards, and good product quality. Due to the special environment and breeding methods of far-reaching sea, the seedlings of fish are generally large-scale seedlings with a weight of 100-400g, and individual fish varieties even need to put seedlings wi...

Problems solved by technology

[0005] (1) In the prior art, due to the lack of safe and effective transshipment techniques, the cultured fish are prone to stress response and mechanical damage during the land-sea relay transshipment process, which can easily lead to pathogenic infection and disease. Caused large-scale death of transshipped fish and caused serious economic losses to farming enterprises

[0006] (2) In the prior art, certain mechanical means must be adopted for the fish to be caught and transported, which will inevitably cause physiological stress response of farmed fish, resulting in decreased immunity and body surface damage, but there is currently no effective Measures or technical products to reduce the stress response of fish, resulting in a high risk of disease during transshipment, affecting the survival rate of transshipment

However, for deep-sea aquaculture production, what substances to use and how to use them efficiently can effectively reduce the body stress damage of suitable fish during live transshipment, enhance the immune response, and reduce the risk of pathogenic infection. , requires original research and development, and there are certain technical difficulties
