Description
Technical Field
The embodiment of the invention relates to the technical field of carp specific pathogen free indoor culture, and particularly relates to carp specific pathogen free indoor culture equipment.
Background
A specific pathogen free animal is one in which no specific microorganisms or parasites are present in the body, but non-specific microorganisms or parasites are tolerated. Therefore, it is actually a healthy animal without infectious diseases. The animals are the most widely used experimental animals at home and abroad at present, and the source of the animals can be descendents bred by sterile animals, or the animals can be fostered by SPF (specific pathogen free) parental animals in an environment of an isolation barrier facility after embryo dissection. It does not carry microorganisms which are pathogenic to the human or animal body itself, but does not exclude microorganisms which can spread vertically through the placental barrier.
Carp belongs to demersal omnivorous fish, and is eaten by both meat and vegetables. The bait has wide spectrum, developed kisses bones and is often eaten by hunch mud. The carp is a low-temperature-changing animal, the body temperature changes along with the change of water temperature, and the constant body temperature is not required to be maintained by consuming energy, so the total amount of bait required to eat is not large. Meanwhile, common carp belongs to a fish species without stomach like most freshwater fishes, and has short intestinal tract and high metabolism speed, so that the common carp has a habit of eating less frequently. The digestion function of the carps is greatly related to the water temperature, and the season of food intake is very strong. As the living standard of people is continuously improved in recent years, the edible demand of carps is gradually increased, and as the growth of the carps is greatly limited by seasons, spring carp viruses, koi herpesviruses and carp edema viruses are easily generated in fish groups in spring and autumn, so that the fish groups die in a large range, and the yield of the carps is seriously influenced, the special pathogen-free indoor carp breeding equipment is urgently needed.
As the carp is cultured and the water body is required to have high dissolved oxygen and fresh water quality, the cleanness of the water quality can be kept to possibly avoid the generation of viruses, so in the production, water change is often needed to keep the dissolved oxygen in the water, the carp generally inhabits in a deeper water of a bottom water area, the distribution of the dissolved oxygen in each water layer in a pond is extremely uneven, the dissolved oxygen of the lower water layer is always in a lower state no matter in daytime or at night, and oxygen-deficient water in the water area far away from a water outlet is not completely discharged during water change, so that the growth of the carp is extremely unfavorable.
The existing carp breeding equipment is limited by immature technical development and economic conditions, all fry are often placed in a water pool, when infected fish appears in the water pool, due to difficulty in catching and lack of the breeding pool, the infected fish can not be isolated in time, pathogens carry the fish to be in direct contact with other fish in the water pool, the propagation of pathogens such as bacteria and parasites can not be effectively controlled, a large amount of fish colonies are infected and die, and the economic benefit of carp breeding is affected.
