Sweet-water fish culturing method

Abstract

The invention discloses a sweet-water fish culturing method which comprises the following steps: (1) digging a fishpond: a fishpond II adjacent to a reservoir or a fishpond I up and down, wherein a higher water inlet and a lower water outlet are formed in the fishpond II, at least one ridge with a certain gradient is arranged from the water inlet to the interior of the fishpond II, and aquatic plants grow on the ridges; (2) culturing fish fries; and (3) pouring slurry for at least two times per day within 1-60 days since the fish fries are put into the fishpond, feeding fish meal, starting to feed fish feed from the 60th day when the fish fries are put into the fishpond, wherein the fish feed comprises cotton seeds, corn, distillers grains, pine needle meal, dried tangerine or orange peel and tangerine seeds. According to the water inlet and water outlet with a certain gradient formed in the fishpond, the fish has a good activity place and clean water flow in the fishpond. The fish is scientifically fed by green feed, so that wading of fishes is promoted, the activity level of the fishes is increased, the constitution of the fishes is enhanced, the feeding ability of the fishes is increased, the fish diseases are reduced, and rapid growth of the fishes is promoted.

Description

technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a method for cultivating living water fish. Background technique [0002] In the breeding process of aquatic products such as fish, they usually rely on natural water resources by rivers, lakes or coasts for stocking. This method of farming is low in cost, but in the event of natural disasters, river pollution, storms or sudden changes in weather, It will cause fish to die or run away on a large scale, resulting in heavy losses for fish farmers. There is another method of breeding and stocking fish by digging ponds. By adding artificial feeding bait, the rapid growth of fry can be promoted. This kind of stocking The grown fingerlings have low nutrient content, poor taste, and low economic value. Contents of the invention [0003] In view of this, the object of the present invention is to provide a kind of...
