Problems solved by technology

The traditional prawn farming method is to directly stock shrimp seedlings into large ponds when the water temperature reaches 20°C or higher. This farming method has a low survival rate, small size of adult shrimp, large individual differences in adult shrimp, poor quality, low yield, and economical. Poor benefit

Embodiment 1

[0025] A high-yield ecological breeding method for prawns, comprising the following steps:

[0026] (1) Shrimp pond design: set up three shrimp ponds connected in the shape of "品", and lay pipelines for sewage in the center of the bottom of the pond. The shrimp pond is a shrimp breeding pond, and the two shrimp ponds at the middle and lower ends of the "product" shaped shrimp pond are respectively a medium shrimp cultivation pond and an adult shrimp cultivation pond. The bottom of the shrimp cultivation pond and the middle shrimp cultivation pond The height difference at the bottom is 30cm, and the height difference between the bottom of the pond and the bottom of the shrimp cultivation pond is 50cm, and the height of the bottom of the shrimp cultivation pond and the bottom of the shrimp cultivation pond is The difference is 80cm, wherein the bottom of the shrimp fry breeding pond is the highest, the culture area ratio of the shrimp fry breeding pond, the medium shrimp cultiva...

Abstract

The invention relates to a prawn high-yield ecological breeding method which includes the steps of prawn pool designing, prawn pool disinfecting treatment, breeding management, harvesting and fishingand the like. The breeding management step includes the substeps of prawn larva breeding, middle-aged prawn breeding and adult prawn breeding. By means of the breeding method, breeding of various aquatic products can be realized within a short period of time, the total yield of the aquatic products can be remarkably increased in the same time, the breeding species of the aquatic products are increased, the growth of aquatic plants can be effectively controlled, the artificial interference in the water body environment is reduced, and labor resources are saved; operation is simple and clear, energy conservation and emission reduction are realized, energy consumption is reduced, and more importantly, the bred prawn is high in yield, healthy and high in nutritional value; on one hand, the nutritional value is not lost, and on the other hand, the market requirements are well met.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to a high-yield ecological cultivation method for prawns. Background technique [0002] Prawn, scientific name "prawn", also known as "one-horned new prawn", "Chinese prawn". Also known as "prawn", "horned shrimp", "white shrimp", "phoenix shrimp". Soft carapace, shrimp family. The body length is about 8cm. There are many sunken parts on the body surface, and short hairs grow on them. The forehead is straight, only the upper edge has 7-9 teeth. The carapace has obvious heart gill grooves and heart gill ridges, liver grooves are obvious, with liver spines, antennae spines and eye spines, no cheek spines. The first three pairs of legs have basal spines, the first step has seat spines, the fifth has no extremities, the seventh has lateral gills, and the third jaw has no limbs. It is an important economic species and is the object of artificial bree...
