[0036] System parameters: Effective breeding water body 1290L, air oxygenation DO maintained above 6.0mg / L, salinity 32±1, water temperature 18℃~22℃, pH 8.1~8.3.

[0037] The size of juvenile abalone selected is about 1-2cm in shell length, and the breeding density is 1300 / m 2, the water flow rate is 300L / h, and the photoperiod is 12:12 (Dark:Light). During the cultivation process, feeding is carried out twice a day (6 o'clock in the morning and 16 o'clock in the afternoon), and the daily feeding amount is 4% of the total weight of abalone. % (fresh kelp combined with compound feed), the water circulation should be stopped after each feeding, and it will return to the normal level after 2 hours. Sampling was carried out every other month to determine the growth and survival of juvenile abalone. After 60 days of cultivation, the average length of juvenile abalone shells is 3.2±0.17cm, the survival rate reaches 94%, and the specific growth rate reaches 0.35%day -1 .

Abstract

The invention belongs to the aquaculture engineering field, and particularly relates to a closed circulating aquaculture system suitable for multilayer stereoscopic cultivation of abalone. The circulating aquaculture system suitable for the multilayer stereoscopic cultivation of the abalone is characterized in that a plurality of aquaculture tanks are installed on a support, a plurality of wave generation hoppers hinged on the support are arranged above each aquaculture tank, the interior of each aquaculture tank is divided into a plurality of tank bodies which are communicated, one water outlet side of each aquaculture tank is communicated with a filter tank, the lower portion of each filter tank is a sewage collection tank, a filter device is arranged on the upper portion of each filter tank, all the filter tanks are respectively communicated with a temperature regulation box with a heat exchanger installed inside, the heat exchanger is communicated with a refrigerator, temperature of seawater is controlled through the refrigerator and the heat exchanger, a water pump, a foam separator, a biological tank and an oxygen tank are sequentially communicated with the temperature regulation box, the foam separator is communicated with a jet injector, and an aeration disk communicated with an air pump us arranged in the biological tank. The circulating aquaculture system suitable for the multilayer stereoscopic cultivation of the abalone has the advantages of continuously reusing aquatic water, being capable of controlling temperature, manually generating waves, achieving rapid and thorough water purification treatment, being convenient to operate, saving energy and protecting environment and the like.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a closed circulation aquaculture system suitable for high-density, multi-layered and healthy cultivation and cultivation of abalones of different species and specifications. Background technique [0002] In nature, Baoxi inhabits reef areas with clear water flow and wave impact, so as to obtain sufficient dissolved oxygen, avoid predation and increase the probability of catching prey organisms; while in aquaculture production, wave-making devices are rarely used to simulate nature. environmental conditions. Studies have shown that waves in natural sea areas will affect the growth and survival of New Zealand rainbow abalone (Haliotis iris), but there have been no reports on the artificial wave-making in abalone's indoor factory recirculating aquaculture system to simulate the natural environment . Temperature is an important environmental factor, which can directly or indi...
