RIASSUNTO
The content and goal of our research is to establish growth model for California bass in intensive aquaculture base. The growth model is divided into two stages. We recorded in detail the amount of bait we fed every day and the weight of the fish seven times. Because the weight data which reflecting the growth of fish are only 7 times during the whole breeding cycle, we use interpolation method to complement the growth process. We insert a calculation data between each two of the seven original body weight data and get a total of 13 data for calculating growth models. According to the general law of biological growth and development, we divided the cultivation process of California bass into two stages. For these two stages, growth models were established respectively. From the original data, we sorted out the total amount of bait and the total weight gain of fish at each stage, and calculated the bait coefficients at each stage. Through the study of the growth model of California perch fry stage, we should strengthen the guidance to the general farmer's aquaculture process.
