Cultivation method for neocaridina denticulata

Abstract

A cultivation method for neocaridina denticulata is characterized by including during building of a culture pond, laying a river sand layer, namely laying coarse river sand and fine river sand mixedly, at the bottom of the pond, laying stones, namely cobblestones 2-5cm in diameter, at the sunward bottom of the pond and ensuring that the laying area of the stones accounts for 40% of the area of the bottom of the pond; before water injection, planting hornworts in a rock area of the bottom of the pond, ensuring that the planting area of the hornworts accounts for 10% of the area of the whole culture pond, planting pondweeds in a river sand area, and ensuring that the planting area of the pondweeds accounts for 10% of the area of the whole culture pond; after water injection, planting water hyacinths on the water and ensuring that the planting area of the water hyacinths accounts for 15% of the area of the culture pond. The cultivation method has the advantages that life habits of the neocaridina denticulate are observed, natural growing environment is simulated during cultivation, and the method of coordinating the river sand and the stones with the nutrient aquatic plants at the bottom of the pond is adopted, so that a good growing environment is provided for the neocaridina denticulate, nutrition of water is improved and yield is increased; when the method is adopted for cultivation of the neocaridina denticulate, massive death incidents occur rarely, and large-scale cultivation is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating wild rice shrimp. Background technique [0002] Wild rice shrimp is rich in protein and has high nutritional value. Its meat is as soft and easy to digest as fish, but it has no fishy smell and bone spurs. It is also rich in minerals (such as calcium, phosphorus, iron, etc.). It is also found that rice shrimp is rich in iodine, which is very beneficial to human health. According to scientific analysis, the edible protein of wild rice shrimp accounts for about 16-20%. [0003] Due to the small size of the wild rice shrimp, the breeding has strict requirements on the environment, and large areas of death or low yields often occur in artificial breeding. Contents of the invention [0004] The purpose of the present invention is to provide a kind of feasible method for cultivating wild rice shrimp, reach the effect of increasing output. [0005] In order to sol...
