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 factory-like circulated water mixed cultivation method of oplegnathus punctatus and cynoglossus semilaevism, belonging to the technical field of aquaculture. According to the method, juvenile oplegnathus punctatus and cynoglossus semilaevism are cultivated in a circulated water cultivation system together, by adjusting the cultivating size, the cultivating order, the cultivating density ratio, the management strategy and the water quality condition of the two marine fishes, the interspecific competition is reduced or avoided, mixed cultivation of oplegnathus punctatus and cynoglossus semilaevism is achieved, and the cultivation efficiency of a unit water body is improved. By adopting the method, the interspecific competition of the two fishes is effectively avoided, the space of a cultivation water body is efficiently utilized, the temperature control cost of the cultivation water body is lowered, the cultivation efficiency of the unit water body is remarkably improved, the water flow speed inside a cultivation pond is increased, the discharge efficiency of granules such as the manure inside the cultivation pond is increased, the water treatment pressure of the circulated water cultivation system is alleviated, and the cultivation biological capacity of the cultivation system is remarkably increased. The invention provides a novel idea and a novel method for factory-like circulated water cultivation of marine fishes.

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...
