چکیده
Abstract: It was important to sustainable development of aquaculture industry used biological method and biotechnology to treat the waste of aquaculture. In this paper, an airlift recirculating aquaculture system was designed and polychaete worms was cultured in it. According to the different food level experiment, the growth of Perinereis aibuhitensis was tested in each system which marked M1,M2,M3,M4 and M5 throughout the percent of weight from 0,6%,12%,18% and 24%. The water parameters also were tested. The results showed that : In the M3 groups, production of P.aibuhitensis is the highest as 2.36 g/m,other groups was negative production. Feded on the residual feeds and feces of flounder fish,worms mean weight was increased,the maximum in M4 was 1.570g and maximal was 0.986g in M3 in the 40 days.The results could give a novel method to biological utilizated the waste of aquaculture.

Assessing the carrying capacity of Perinereis aibuhitensis in a Chinese estuarine wetland using a GIS-based habitat suitability index model
Increasing attention is being paid to estuarine benthic community conservation and restoration globally. In this study, a GIS-based habitat suitability index (HSI) model was utilized to estimate Perinereis aibuhitensis (Grube, 1878) carrying capacity in estuarine wetlands of the Zhimai River, eastern China. Eight parameters were investigated, including sand content, salinity, pH, and petroleum ...

This study was conducted in order to compare the hornwort aquatic plant (Ceratophyllum demersum) with an artificial filter for purification in a recirculating aquaculture system (RAS). At first, the fluctuation of nitrogen components of the water reuse system equipped with artificial filtration was evaluated. Experiments were performed during three months. The hornwort aquatic plant was collect...

Dietary cholesterol has been shown to be essential for several crustacean species. However, cholesterol requirement of narrow-clawed crayfish has not been reported. Therefore, a 12-week feeding trial was conducted to determine deitary cholesterol requirement of narrow-clawed crayfish. Juvenile crayfish with an average body weight of 13.8±1 g mean weight were intensively stocked in an indoor rec...
