Embodiment Construction

[0023] 1. Pond conditions

[0024] Site selection: Build a shrimp pond near the water source and where the water quality is clean and pollution-free. Water quality: The water source is pollution-free and meets the national fishery water use standard. Pond environment: Slope ratio 1:2.5-3, pond bottom silt 10-15 cm. Pond area and water depth: The pond for seedling cultivation should not be large, preferably 1-2 mu. The water depth is 1.5-2 meters. Aeration equipment: Generally, shrimp ponds below 5 mu are equipped with a 1.5 kW impeller or an aeration machine.

[0025] 2. Pond preparation

[0026] 2.1 Field removal and disinfection

[0027] Drain the pond water 15 days before stocking, use 75-150 kg of quicklime to clear the pond per mu, and enter 80-100 cm of water after a week. Sprinkle the whole pool with 40-50 kg of tea cake per mu or use 15-25m of bleaching powder 3 The whole pool is splashed to kill the harmful organisms and pathogens in the pool. After 50-7 days,...

Abstract

The invention discloses a freshwater shrimp blocking-net-type intercropping method and belongs to the technical field of freshwater aquaculture. A blocking-net-type freshwater shrimp and trionyx sinensis intercropping mode is adopted, and aspects like culture pond building, fry stocking, culture management and feed quality are comprehensively improved; freshwater shrimp and trionyx sinensis are separated by using a blocking net for respective culture, and freshwater shrimp small in body size can enter a deep water area to serve as living food for trionyx sinensis, so that feed consumption of trionyx sinensis can be lowered, and culture cost of trionyx sinensis is lowered while culture quality of the same can be improved; culture density of freshwater shrimp can be controlled effectively, cannibalism is reduced, and improving of culture quality and yield is facilitated. Ecological niche characteristics of different organisms like alga, water plants, grey chub, freshwater shrimp and trionyx sinensis are taken into consideration comprehensively, a proper intercropping proportion is set, ecological balance of a culture pond is maintained, and water quality is adjusted, so that the method is an environment-friendly and high-efficiency culture mode and suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of freshwater aquaculture, and in particular relates to a block-type nesting method for freshwater green shrimp. Background technique [0002] Shrimp farming is one of the most representative industries in the aquaculture industry. In recent decades, the rapid development of the shrimp farming industry has created significant economic benefits. The economic value of the cultured species is relatively high, and the breeding cycle is short. It is a capital-intensive and technology-intensive industry with relatively high benefits. The structure of cultured species, meeting domestic and foreign markets and people's living needs are of great significance, and are of great significance to increasing fishery production and fishermen's income. Freshwater freshwater shrimp is a typical freshwater shrimp, and its product price has been firm and rising year by year. [0003] Freshwater shrimp, scientific name: Macrob...
