Problems solved by technology

At present, there is little research on the special feed for California perch, and most of them use natural bait as the feed, which has the disadvantages of high cost, easy to pollute water quality, unstable quality, and easy introduction of pathogens such as parasites, bacteria and viruses.
Moreover, factors such as opening rules, nutritional requirements, and feeding preferences of different fry are not considered, and the effect of attracting food is poor, which cannot ideally promote the growth and development of fry.
