The quantity of fries depends on the manpower number when buying, produces the error easily, and the fries is scratched easily in the transportation moreover, in case contact the planktonic virus in the ocean, very easily takes place to infect, finally leads to the fries death. Some dead fries can sink into the net bottom, the death total number of the fries can not be counted, and escape, theft and the like can also occur in the growth process. Therefore, the total number of the fishes in the net cage is dynamically changed, and the total number of the fishes can be obtained in real time, so that accurate feeding can be guided, and loss can be prevented in time.
The current commercial net cage BIOMASS estimation products are imported from abroad, such as ABS of Biosonics corporation in Norway, BIOMASS DAILY of VAKI corporation in iceland, etc., and these devices are based on statistical methods, and use a small amount of samples to estimate the BIOMASS in the whole net cage, which is easy to have the problems of large error and large fluctuation. Moreover, calculating the body length of the fish in a sonar or infrared mode is easily influenced by the gesture and the overlapping of the fish, and the given biomass estimation result is relatively rough and cannot provide high-quality data for the cultivation operation. The offshore water depth of China is shallow, the sonar is distributed on the water surface and is easily influenced by the noise of the sea waves on the water surface and the seabed on the sea, and the statistical sample size is possibly insufficient due to different habits of fishes, so that the offshore culture requirement of China cannot be well met.
