Abstract

The invention relates to a method for mixed culture of pearl gentian grouper and grouper bream in industrialized circulating water. The invention belongs to the technical field of aquaculture. The weight of the pearl gentian grouper is 30-40 g, and the weight of the grouper is 1.5-2.0 g. times, adjust the breeding density of the pearl gentian grouper to 80-120 fish / m3, and the stocking density of the grouper is 1 / 5-1 / 6 of the pearl gentian grouper. The present invention mixes pearl gentian grouper and grouper juveniles in a recirculating aquaculture system, and reduces or avoids interspecific competition by adjusting the stocking specifications, stocking order, culture density ratio, management strategy and water quality conditions of the two seawater fish , realize the mixed culture of pearl gentian grouper and grouper bream, and improve the efficiency of culture per unit water body.

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...
