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 lobster and river crab, which comprises: opening an annular ditch in the polyculture pond after cleaning the polyculture pond, and setting anti-escape devices around; disinfecting the pond with quicklime after drying; draining water, Apply compound fertilizer and fermented organic fertilizer; plant aquatic plants in polyculture ponds and apply compound fertilizer; in February, stock young crabs with a specification of 10-15g / cub, and the amount of stocking is 450-550 / mu; in April In the first ten days of the month, put larvae at a rate of 250‑350g / mu; in late May, put larvae with a size of 3‑5cm at a rate of 2300‑2700 fish / mu; Feeding with compound feed, in July-August, feeding with vegetable bait and full-price compound feed, in September-October, feeding with miscellaneous fish and full-price compound feed, and feeding lobster with pellet feed throughout the whole process; and Water quality management and disease control.

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...
