Embodiment 1

[0022] A kind of mixed breeding method of porphyra and semi-smooth tongue sole in industrial circulating water, the specific operations are as follows:

[0023] Each set of recirculating aquaculture system in the semi-smooth tongue sole breeding workshop of Oriental Ocean Laizhou Branch is composed of a water treatment unit composed of a microfiltration machine, protein foam separator, ultraviolet lamp, ozone, oxygen cone, and biological filter, and 10 breeding ponds. The pool is adjusted to a water depth of 80cm, and the effective breeding water body is about 24m 3 .

[0024] Stocking quantity and specifications: Two sets of systems are used. Each pond is stocked with 500 porpoises with an average weight of 72.4 grams, a total of 10,000; and 1,200 half-tongue soles with an average weight of 150.4 grams, a total of 24,000. Mixed breeding is implemented.

[0025] Stocking sequence: first stock the semi-glossy tongue sole in the system, and after about 4 days of stable food int...

Abstract

The invention discloses a mixed culture method of grouper bream and half smooth tongue sole in circulating water in an industrialized manner. Belonging to the technical field of aquaculture, the invention mixes juvenile porpoise and half smooth tongue sole in a circulating aquaculture system, and reduces or avoids species by adjusting the stocking specifications, stocking order, culture density ratio, management strategy and water quality conditions of the two kinds of sea fish. Inter-competition, realize the mixed culture of porphyra and semi-smooth tongue sole, and improve the efficiency of unit water body culture. The invention can effectively avoid competition between two kinds of fish species, efficiently utilize the space of the cultured water body, reduce the cost of temperature control of the cultured water body, significantly improve the breeding efficiency of the unit water body, increase the water flow velocity in the cultured pond, improve the removal efficiency of feces and other particulate matter in the cultured pond, and reduce circulation. The water treatment pressure of the aquaculture system significantly increases the biological carrying capacity of the aquaculture system. The invention provides a new idea and a new method for industrialized circulating aquaculture of seawater fish.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and specifically relates to a method for mixed culture of porphyra and half smooth tongue sole under the condition of industrial circulating water culture. Background technique [0002] Oplegnathus punctatus belongs to the order Perciformes, the genus Oplegnathus punctatus, and is mainly distributed in North Korea, Japan, and Taiwan Island of China, the South China Sea, the East China Sea, the Yellow Sea and other sea areas. It has tender meat, beautiful appearance, and high Economic value and ornamental value, it eats ferociously and grows fast, but it is particularly sensitive to the stress of breeding density. Under conventional breeding conditions, the stocking density of grouper with a weight of 50-100g exceeds 5kg / m 3 When the species is infested, its body surface is prone to festering, and the intraspecific competition is intensified, and the growth rate and bait utilization rate are s...
