Problems solved by technology

The species of lobster and river crab are different, and their living habits and feeding methods are very different. At present, there are not many studies on the polyculture of lobster and river crab. The polyculture technology is immature, and there are lobes in the process of polyculture The disadvantages of low survival rate and slow growth of fish and river crab reduce the economic benefits of farmers

Embodiment 1

[0027] The ecological polyculture method of a kind of lobster and river crab that the present invention proposes comprises the following steps:

[0028] A. Pond selection: Select a pond with an area of ​​15 mu, a rectangle, close to the water source, convenient inflow and drainage, fresh water source and no pollution as a polyculture pond, and clean up the polyculture pond so that the slope ratio of the polyculture pond is 2:1 ; In the polyculture pond, an annular ditch is opened around the polyculture pond, wherein the depth of the annular ditch is 2m, and the width is 80 meters. The area of ​​the annular ditch is 30% of the total area of ​​the polyculture pond; Wooden stakes, where the plastic is secured to the stakes with wire to form a guard;

[0029] B. Disinfection and fertilization: Inject water into the polyculture pond after drying the pond for one week. The water injection height is 1 / 4 of the height of the polyculture pond, and then spray the whole pond with quickli...

Abstract

The invention discloses an ecological polyculture method of Tor brevifilis brevifilises and river crabs. The ecological polyculture method comprises the following steps: cleaning a polyculture pond, digging an annular ditch in the polyculture pond, and arranging anti-escape devices on the surrounding; solar irradiating the pond, and sterilizing with quick lime; draining, and applying a compound fertilizer and a fermented organic fertilizer; planting water plants in the polyculture pond, and applying the compound fertilizer; stocking 450-550 pieces of young crabs with weights of 10-15g in each acre in February; stocking 250-350g of larva snails in each acre in early April; stocking 2300-2700 pieces of Tor brevifilis brevifilises with specifications of 3-5cm in each acre in late May; after stocking the river crabs, feeding the river crabs with a complete formula feed in June, and feeding the river crabs with a plant feed and the complete formula feed in July and August, feeding the river crabs with trash fish and the complete formula feed in September and October, and feeding the Tor brevifilis brevifilises with a pellet feed in the whole process; and managing the water quality and controlling diseases.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to an ecological polyculture method of lobster and river crab. Background technique [0002] Osteophytes belong to Osteostichthyes, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, Osteophytes, and Osteophytes subgenus. They are widely distributed in the Lancang River, Yuan River, Yangtze River, Pearl River and other water systems in my country. They are only seen in Vietnam abroad. of the Red River system. The growth rate of the petaled fish is average. The body length of 1 winter age fish is 19-19.5 cm; the body length of 2 winter age fish is 27.6 cm; the body length of 3 winter age fish is 33.8-34.6 cm; 0.5-1 kg, up to 8 kg, is a large and medium-sized freshwater economic fish in the production area. The river crab is a large crustacean with a body divided into 21 segments. Since the head and thorax segments are healed with each other, the whole body is divided into two parts: th...
