Embodiment 1

[0019] A kind of mixed breeding method of pearl gentian grouper and grouper sea bream in industrialized circulating water, the specific operations are as follows:

[0020] Each set of recirculating aquaculture system in the grouper aquaculture workshop of Oriental Ocean Laizhou Branch is composed of a water treatment unit composed of a microfilter, protein foam separator, ultraviolet lamp, ozone, oxygen cone, and biological filter, and 10 aquaculture ponds. Each breeding pond is adjusted to a water depth of 95cm, and the effective breeding water body is about 30m 3 .

[0021] Stocking quantity and specifications: A system is selected, and each pool is stocked with 3,500 pearl gentian groupers with an average weight of 32.5 grams, a total of 35,000; 700 groupers with an average weight of 50.2 grams, a total of 7,000, and mixed culture is implemented.

[0022] Stocking sequence: the pearl gentian grouper is first stocked in the system, and after about 3 days of stable food inta...

Abstract

The invention discloses a factory-like circulating water mixed cultivation method of tiger giant grouper and oplegnathus punctatus, and belongs to the technical field of aquaculture. The method comprises the following steps: selecting tiger giant grouper with body weight of 30-40g, wherein the body weight of the oplegnathus punctatus is 1.5-2.0 times that of the tiger giant grouper, and adjusting the cultivation density of the tiger giant grouper to 80-120 per cubic meter, wherein the stocking density of the oplegnathus punctatus is 1 / 6-1 / 5 of that of the tiger giant grouper. The juvenile fishes of the tiger giant grouper and the oplegnathus punctatus are cultivated in a circulating water cultivation system in a mixed manner, the interspecific competition is weakened or avoided by adjusting the stocking size, stocking order, cultivation density ratio, management strategy and water quality condition of the two sweater fishes, the tiger giant grouper and the oplegnathus punctatus are cultivated in a mixed manner, and the unit water body cultivation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a mixed culture method for pearl gentian grouper and grouper bream under the condition of industrial circulating water culture. Background technique [0002] Pearl gentian grouper, commonly known as dragon tiger grouper or pearl grouper, is a hybrid grouper bred by female brown-spotted grouper and male saddle-banded grouper. It grows fast and has strong disease resistance. It is a kind of nutritional value and Fish with high economic value has become one of the main cultured species of grouper in my country at the present stage, and has broad industrial prospects. However, at present, the main breeding methods of this fish are coastal ponds and offshore cages, and the breeding methods are relatively extensive. It needs to be improved urgently; Oplegnathus punctatus belongs to Perciformes, Oplegnathidae, and the genus Oplegnathus. It is mainly distributed in North Ko...
