The latest technology of mandarin fish culture

The latest technology of mandarin fish culture is as follows:

1. Life habits of Siniperca chuatsi: Bottom fish live in clear water and rivers, lakes and water conservancy projects with certain flowing water, especially shallow lakes rich in aquatic plants. Generally, they ambush underwater in broad daylight and move around at night to find food. They have the habit of nesting and growing in buildings and don't like social animals. The suitable water temperature for daily life is 15 ~ 32℃. When the water temperature is lower than 7℃, they don't move and don't eat much.

2, Siniperca chuatsi feeding habits: carnivorous fierce fish, like to eat with other fry after hatching, love to eat live bait, and kill each other when hungry. The fingerling link can swallow 70 ~ 80% of fingerlings equivalent to other cultured fish, and the specifications and models of bait fish can only be swallowed according to their specifications.

The rest.

Area of Siniperca chuatsi culture pond: the total area is 4 ~ 6 mu, at least not less than 1 mu, and the larger area is not more than1mu. The total area of the pond is too small, and the water body changes greatly and is out of control. The total area of the pond is too large, and the bait fish are relatively dispersed, which is not conducive to the feeding of Siniperca chuatsi. The pond rises with the wind, running east and west, and the width-height ratio is 3: 2. Dig the pond with flat bottom silt, sandy loam and little or no silt.

Supporting production of bait fish: the bait fish in the main culture pond of Siniperca chuatsi can be fed 1 month under normal conditions, and the Siniperca chuatsi can be fed 1 month, and the body length can generally reach1~14cm.
