Chinese chuatsi fish, also known as guppies, seasonal flower fish, etc., belongs to the perch order, Mandarin fish genus, its distribution is very wide, the major river systems and freshwater lakes are reproduced, Mandarin fish meat tender, less spiny, tasty, nutrient-rich, is the seat of the delicacies by the vast majority of consumers favor. In the pond not only can be mixed with a small amount of Mandarin fish to remove the wild fish, but also specialize in pond rearing, is currently one of the popular species of freshwater aquaculture.

I, habits

Chiniperca chuatsi is a typical carnivorous fish, in artificial feeding, can be fed dead fish, dead shrimp and so on. Male fish mature at the age of three, female mature at the age of four, its growth rate is faster, the year up to 50 ~ 100 grams, the second year up to 0.5 kg or so, the third year can grow to 1 ~ 1.5 kg.

Two, pond conditions

Chinese chuatsi fish adult fish culture pond, the area should be 3 to 8 acres, the water depth of 1.5 meters or more, the depth of water in the summer should be about 2.5 meters, the substrate is best sandy loam, less humus, water supply is sufficient, the water quality is fresh, there is running water is better. Requirements for pool water dissolved oxygen 5mg / L or more, PH value of 7 ~ 8, transparency of more than 30 centimeters.

Three, bait fish cultivation

Bait fish breeding area for Mandarin fish pool 3 to 4 times. From the Siniperca fish palatability and economic considerations, the bait fish generally choose silver carp, crucian carp and other species, the stocking density of mu put the fish fry 30 to 500,000 tails. Fry stocking, without immediate feeding, to be reduced in the number of zooplankton, fish fry around the pond foraging, start feeding soybean milk or other feed. In the pre-cultivation period, the feed is eaten up to add, while in the later stage of the bait fish specifications should be controlled, the length of the bait fish will be controlled in the Mandarin fish body length of 1/2 to 1/3 between.

Generally stocked 8 to 10 cm Mandarin fish species, bait fish should be controlled at 3 to 4 cm.

Four, Siniperca fish stocking

Mu can be stocked with 800 to 1,000 Siniperca fish species of 8 to 10 centimeters when monoculture Siniperca fish. Can also be mixed in the Siniperca fish pool some fast breeding fish, in order to serve as live feed. Generally, 200 to 400 pairs of tilapia or 60 carp of two-winter age are stocked per mu. The fish pool is divided into two halves with a thin net, one side raising Mandarin fish, one side raising other fish, so that the breeding of young fish through the thin net to become Mandarin fish food, while the activities of the Mandarin fish do not hinder the quiet reproduction of other fish.

V. Feeding management

1, baiting: the use of spacing bait fish, in the early and late breeding, feeding every 7 to 10 days, feeding every 5 days or so in the middle of the feeding, should be kept Siniperca chuatsi fish and the number of bait fish ratio of 1:5 to 10, bait fish is too little, it will affect the Siniperca chuatsi fish feeding and growth, too much is prone to cause hypoxia floating, the growth of Siniperca chuatsi fish is unfavorable.

2, water quality management:

We should often add and change new water, especially in June to September, every 5-7 days to add and change new water once, each time 15-20 cm, so that the water to maintain fat, live, cool, tender, and promote the healthy growth of Mandarin fish. Bitter grass, black algae and other submerged plants can be planted around the pool to provide a hiding place for the fish and at the same time purify the water. Sprinkle lime water every 15-20 days, 15-20 kilograms each time. Timely and reasonable opening of the oxygenator, in order to increase the amount of dissolved oxygen in the pool water, to prevent fish hypoxia, at the same time, should be prepared for some oxygen enhancers, which can be used to rescue the head of the fish in the lack of oxygen floating.
