Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to a method for culturing red swamp crayfish, and particularly relates to a method for high-density culture of red swamp crayfish in an outer pond.
Background
The red crayfish (Latin name: Cherax quadricarinatus) is also called Australia freshwater crayfish, the original product Australia is exactly like crayfish in the sea, and the red crayfish is one of the most famous and expensive freshwater economic crayfish species in the world. The shrimp body is brown green, and the top end of the outer chela is provided with a fresh red zone with membrane quality, so that the shrimp is beautiful and good-looking, and is known as red-chela shrimp. The red swamp crayfish is a omnivorous animal. Under natural conditions, organic debris, periphyton algae, filamentous algae, roots, leaves and debris of aquatic plants are mainly eaten. Especially green plants like herba Eichhorniae, fructus Cucurbitae Moschatae, herba Eichhorniae, herba Spirodelae, and herba Hedyotidis Diffusae. The animal food is like limnodrilus, earthworm, egg, pupa, snail, clam, fish, etc. The red swamp crayfish can live in rivers, reservoirs and ponds and can be hidden in a concealable place in a water body in the daytime; the people find food at the evening and before dawn, like to move at night and crawl at the bottom of the camp. Often crawl or hide in natural caves and artificial caves of the pond in gaps of bricks, tiles and gravels, and have hole digging capability in softer pond bottoms. Sometimes also along the walls of the pond, in the roots and dense leaves of the aquatic plants.
The adult crayfishes of the red swamp crayfish have strong low dissolved oxygen resistance, can survive with the dissolved oxygen content of 1 mg/L in water and can survive for a long time in a wet state, so the adult crayfishes can endure long-distance transportation and are beneficial to the supply market of live shrimps. The young shrimp and the parent shrimp with eggs are not suitable for being raised in the water body with low dissolved oxygen, which easily causes the death of the young shrimp and the egg embryo. The dissolved oxygen amount of the water body for raising the brooding parent shrimps and the young shrimps is preferably not less than 4 mg/L. The red swamp crayfish has strong low oxygen-dissolving resistance, can survive when the dissolved oxygen amount in water is 1 mg/L, and can survive for a long time in a moist and slightly water state. The artificial breeding of the red swamp crayfish needs large-scale high-density breeding for cost consideration, the large-scale high-density breeding of the strongly conscious red swamp crayfish needs to face a plurality of challenges, and particularly when the red swamp crayfish is bred in an outer pond, the survival rate is difficult to improve. Patent application No. 201610394121.8 describes a method for cultivating red crayfish.
However, in the process of implementing the prior art, the inventor of the present application finds that the above-mentioned technology has at least the following technical problems:
the black head seedlings are weak in physique and numerous natural enemies of the outer pond, so that the survival rate of the shrimp seedlings is extremely low;
the commercial shrimp can not be fully utilized after the cultivation time is more than 180 days, for example, one year of cultivation in continental land of the Hainan island and one year of cultivation in two seasons of the Hainan island are required, and more fishponds need to be dug if the commercial shrimp are produced once, so that the waste of land resources and the increase of cost are caused;
the commercial shrimps are small in culture quantity due to cost consideration, low in survival rate and low in yield.
