Embodiment 1

[0032] An environment-friendly, healthy and efficient method for comprehensive cultivation of large yellow croaker cages, selecting a sea area suitable for breeding large yellow croakers, and then taking the large yellow croaker cage culture area as the central area, and setting large yellow croaker cages around the large yellow croaker cage culture area. For the shellfish culture area distributed in the net cage culture area, a seaweed culture area distributed around the shellfish culture area is set around the outer periphery of the shellfish culture area;

[0033] In the large yellow croaker cage culture area, put fry when the tide is slow during the low tide period during mid-April to early May and the water temperature is 15°C to 20°C (when the temperature is lower, the choice is fine and there is no wind. The weather is released in the afternoon; when the temperature is higher, it is better to choose to release in cool weather or in the morning and evening). When releasin...

Embodiment 2

[0042] An environment-friendly, healthy and efficient method for comprehensive cultivation of large yellow croaker cages, selecting a sea area suitable for breeding large yellow croakers, and then taking the large yellow croaker cage culture area as the central area, and setting large yellow croaker cages around the large yellow croaker cage culture area. In the shellfish culture area distributed in the cage culture area, a seaweed culture area distributed around the shellfish culture area is arranged around the outer periphery of the shellfish culture area; When the water temperature is between 15°C and 20°C and the tide is low during the small tide, the fry should be released (when the temperature is low, it should be released in the afternoon with fine and windless weather; if the temperature is high, it should be released in cool weather or in the morning and evening), When feeding fry, put 48,000 fish per 1 mu of cages, and breed for 2 years, and feed the large yellow croa...

Abstract

The invention relates to a large yellow croaker net-cage comprehensive breeding method based on environment protection, health and high efficiency. The method comprises the following steps: selectinga sea area suitable for culturing large yellow croakers, then taking a large yellow croaker net cage breeding area a center area, arranging a shellfish breeding area which surrounds the large yellow croaker net cage breeding area on the periphery of the large yellow croaker net cage breeding area, and arranging a seaweed breeding area which surrounds the shellfish breeding area is arranged on theperiphery of the shellfish breeding area. The breeding method can be used for reducing the breeding environment pressure and improving circulating utilization efficiency of the breeding system, the breeding system is reasonable, continuous high yield of breeding products can be promoted, high-efficiency healthy sustainable development of large yellow croaker net cage breeding is promoted, and comprehensive breeding benefits are improved.

Description

technical field [0001] The invention relates to the technical field of seawater aquaculture, in particular to an environment-friendly, healthy and highly efficient net cage comprehensive culture method for large yellow croakers. Background technique [0002] In recent years, the aquaculture industry, especially the marine aquaculture industry, has developed rapidly in my country and even the world with its unique advantages, constantly meeting people's demand for aquatic products. However, due to the single ecological structure of mariculture and the defects of farming methods and scales, the pollution of the breeding sea area is becoming more and more serious, gradually affecting the coastal ecological environment, resulting in the reduction of coastal marine biodiversity. Seawater cage culture mostly adopts high-density bait feeding culture. After long-term large-scale culture, the residual bait and fish metabolic waste produced by it will accumulate in a large amount in t...
