Embodiment 1

[0033] A method for ecological breeding of Macrobrachium rosenbergii, comprising the following steps:

[0034] (1) Nursery pond preparation: choose an indoor cement pond with a size of 1.5 m×4.0 m×0.8 m as the nursery pond, install a heating pipe inside the nursery pond, set a microporous inflatable pipe at the bottom of the nursery pond, connect the microporous inflatable pipe to a blower, and raise seedlings. Paint the inner wall and bottom of the pool with epoxy resin water tank paint specially designed for aquatic products until the surface is smooth. After the paint dries, soak the nursery pool with fresh water for 7 days, and then disinfect it with 15 g / L potassium permanganate solution for 12 minutes. Rinse once with clean tap water, dry, and set aside;

[0035] (2) Preparation of seedling water: dilute concentrated seawater to seawater with a salinity of 12%, filter the seawater with absorbent cotton filter bags after sedimentation, and then sterilize with trichloroiso...

Abstract

The invention provides an ecological young shrimp culture method for macrobrachium rosenbergii. The method includes the steps of preparing a young shrimp culture pond, preparing water used for young shrimp culture, obtaining young shrimp larvas, feeding bait, managing water quality, transferring the young shrimps to another pond, desalting for young shrimp emergence and the like. In the bait feeding process, the young shrimps are fed on natural bait unit cell algae, fairy shrimp nauplii and artificial bait egg custard, the natural bait is environmentally friendly and healthy, the articical bait is rich in nourishment, and nutritional ingredients are not prone to running off; when the water quality is managed, nuisanceless water quality ameliorant and microbial preparations are adopted to adjust the water quality. Hormones and poisonous chemicals are not used in the young shrimp culture process, the young shrimps are high in survival rate and grow healthily and strongly, young shrimp emergence is fast, and the ecological young shrimp culture method is low in cost, high in efficiency and capable of effectively increasing economic benefits of an aquaculture farm.

Description

technical field [0001] The invention relates to a method for cultivating shrimp seedlings, in particular to a method for ecologically cultivating giant macrobrachium rosenbergii. Background technique [0002] Macrobra'chium rosenbergiideman, also known as Malaysian prawn and freshwater long-arm prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide feeding habits, good meat quality and short breeding cycle, etc. It is one of the three largest shrimp species in the world. Its shell is thin and fat, the meat is fresh and tender, delicious and nutritious. In addition to the flavor of general freshwater shrimp, the head and breastplate of mature Macrobrachium rosenbergii is full of gonads, which has a special delicious taste similar to crab roe. Each hundred grams of Macrobrachium rosenbergii shrimp meat contains 20.6 grams of protein, 0.7 grams of fat, and contains a variety of vitamins and trace elements necessary for the huma...
