California bass is a warm-water fish. In aquaculture ponds, it likes to live in a sandy, muddy and non-turbid still water environment and move in the middle and lower layers of water. Young fish like to move in groups, while adult fish are scattered.

The optimum growth temperature of California bass is 20-30℃, and it begins to feed above 10℃. The tolerance to hypoxia is stronger than that of Siniperca chuatsi, and the young fish will float when the dissolved oxygen is1.85 mg/L. Compared with common domestic fish, the young fish have higher requirements for dissolved oxygen in water, generally above 4 mg/L. The California bass grows well in fresh water and can also grow in salty fresh water with salinity of 1%. Generally, a ph of 6-8.5 is required.

California bass is a carnivorous fish. In nature, it has the dual characteristics of mild carnivorous and fierce carnivorous. It is a carnivore and eats a lot. They often feed on aquatic animals such as aquatic insects, shrimp, small fish and tadpoles. Often foraging alone, sometimes insects fly on the water, chase underwater, wait for opportunities to prey, and are agile. Live bait, such as zooplankton, chironomid larvae, earthworms, shrimps, small fish, etc. You can also feed fish and fish pieces.

When eating live bait and fish, California bass has a large intake, fast growth and good fatness. In the juvenile stage, California bass can eat artificial granular bait after being tamed. When the water quality is good and the water temperature is above 25℃, the intake of fresh feed for young fish can reach 50% of the total weight, and that for adult fish can reach 20%. When the feed is insufficient, cannibalism often occurs. Usually, the fry within 1 month after hatching feed on rotifers and small crustaceans; After the fry grow to 5-6 cm, eat a lot of aquatic insects and bait fry; When the body length is greater than 10 cm, small miscellaneous fish will be the staple food.

California bass is a big fish that grows rapidly. The common individual is 0.9- 1.8 kg. 60-70-day-old fish can reach14.5-16cm in length and weigh 40-50g. The growth rate of fish in that year was related to stocking density, feed, water temperature, water quality and water type. Usually, the fry can reach the market specification of 0.5-0.75 kg after artificial propagation in the same year. After breeding for 2 years, the weight is about 1.5 kg. It reached 2.5 kilograms in 3 years. Because the age of sexual maturity is 1-2 winter age, the rapid growth stage of fish is 1-2 winter age, when the annual growth and growth index are the highest, and it begins to slow down at the age of 3.

California bass generally matures for more than one year, and generally enters the spawning period when the water temperature reaches 18-26℃. Culture can be started in Jiangsu when the water temperature reaches 15℃ in the first half of April every year. Whenever the California bass breeding season comes, it will naturally lay eggs and hatch in the parent fish pond. California perch has the habit of nesting and protecting its young. The male fish first digs a nest with a diameter of 60-90 cm and a depth of 3-5 cm in shallow water. Then the male lures the female into the nest to lay eggs, and the male ejaculates at the same time. The fertilized egg is slightly sticky and adheres to the aquatic plants, sand and stones in the fish nest. After spawning, the female fish leaves the nest for food, while the male fish stays at the edge of the nest to guard the fertilized egg to prevent other fish from approaching. California bass is a kind of fish that lays eggs many times. Natural spawning, fertilization and hatching will lead to cannibalism due to the size difference of different batches. In artificial breeding, the spawning batch can be controlled artificially, and the same batch of fry can be cultivated in the same pond, so the survival rate of fry can be greatly improved.
