California bass has become one of the characteristic aquatic products widely cultivated all over the country because of its strong disease resistance, fast growth, short breeding cycle and delicious meat. The national output exceeds 300,000 tons. At present, the feed factory has broken through the technical difficulties of formula and can realize full feed feeding.

Customers who raised California bass in 20 16 years met a good market, and most of them realized considerable profits. 20 17, many customers who have never raised California bass tried to switch to California bass when the market of other species was depressed.

However, due to the influence of low temperature and rainy weather, the fry of Lateolabrax japonicus in California recently appeared some problems, such as white body, white tail, whirling, defecation, less food intake and so on, accompanied by death.

According to the feeding habits of California bass, how to improve the survival rate of California bass culture through scientific feeding methods and get the first bucket of gold in California bass culture? Based on the experience of cultivating California bass in Foshan, the author summarized the scientific breeding methods of California bass in splash culture, aiming at providing reference for farmers.

The culture stage of California bass from splashing period (about 0.3cm in length) to 10 fish-welcoming period (about 10g in weight) is called the splashing period of California bass, which takes about 50-65 days due to the influence of weather, water temperature and fry source.

The food selectivity of California bass is very strong, and it mainly feeds on rotifers, copepods and cladocera larvae in the pond within 5 days after spraying (Figure 2). In the process of water spraying in soil pond, due to the restriction of early bait, it is suggested that the density of water spraying should be controlled at 200,000-300,000 per mu, and the water depth should be controlled at1.0-1.2m..
