Embodiment 1

[0022] A kind of cultivation method of freshwater prawn and wheat ear carp mixed culture, comprises the following steps:

[0023] 1) Choose a pond with sufficient water source and no silt. The depth of the pond is 1.2m. Set up an insulation shed above the pond, and set up 0.6m high anti-escape facilities around it. Set up 3 water inlets and outlets in the pond, and set up a 40-mesh filter at the inlet and outlet. Drain the water in the pond, remove the natural enemies of fish and shrimp, expose to the sun for 3 days, and obtain an empty pond.

[0024] 2) Pond disinfection treatment: put into 0.7m deep water in the vacant pond that step 1) obtains and drop quicklime disinfection and plant reeds after, the coverage area of ​​reeds accounts for 50% of pond area, hang decomposed microbial organic fertilizer on the pond edge, Place a shelter, adjust the water temperature, dissolved oxygen and pH value of the pond to obtain a cultivation pond; the water temperature of the pond is 25...

Abstract

The invention proposes a mixed-culture method for macrobrachium nipponense and pseudorasbora parva. The method comprises the following steps: 1) selecting a pond; 2) disinfecting the pond: putting water with a depth of 0.5-1m into the empty pond obtained in the step 1), throwing quick lime for disinfection, planting aquatic plants, hanging a decomposed microbial organic fertilizer at the edge of the pond, placing a shielding substance, and adjusting the water temperature, dissolved oxygen and pH value of the pond to obtain a cultivation pond; 3) throwing young macrobrachium nipponense and fry;and 4) performing breeding management: from a first week to a seventh week, performing feeding for 2 times every day, wherein boiled primary feed is thrown; and after an eighth week, performing feeding according to a water temperature, wherein traditional Chinese medicine feed is thrown, improving the water quality every 3-5 days, and throwing young grass carps and bellamya quadrata. The culturemethod provided by the invention fully utilizes culture resources, maintains the water quality, reduces small trash fishes in the fish pond, enriches the product structure of aquatic animals, reducesthe risk of production, greatly improves the utilization ratio of the feed, and increases the yield of the aquatic animals.

Description

technical field [0001] The invention belongs to the field of fish and shrimp culture, and in particular relates to a culture method for mixed culture of freshwater shrimp and wheat ear carp. Background technique [0002] Green shrimp is one of the freshwater shrimps with high economic value. It grows fast, has large individuals, reproduces quickly, and has strong vitality. It is widely distributed in freshwater lakes in my country. Freshwater prawns are tender and delicious, rich in nutrition, and contain 16.40g of protein per 100g of edible portion. It is an omnivorous aquatic animal, partial eclipse animal feed, artificial breeding is mainly fed with commercial feed. It likes to live in the slow stream where the aquatic plants are overgrown. The water depth of the habitat varies from 1-2 meters to 6-7 meters. [0003] Pseudorasbora parva, Pseudorasbora parva (Temminck et Schlegel, 1846), is a fish belonging to the suborder Cyprinidae, Cyprinidae, Pseudora subfamily, and...
