Rice-fish-trionyx-krill symbiotic breeding method and method thereof

Abstract

The invention discloses a rice-fish-trionyx-krill symbiotic breeding method, and belongs to the technical field of breeding. The rice-fish-trionyx-krill symbiotic breeding method comprises the following specific steps that before breeding, submerged plants and rice are planted in breeding ponds; during breeding, three layers of net enclosures are symmetrically laid in the two breeding ponds, and then breeding throwing is carried out; and during regular maintenance, a sound wave fish expelling device is periodically used for expelling fishes in culture ponds into detection ponds, and large-volume aquatic organisms such as the fishes are counted from a counting isolation fence between the culture ponds and the detection ponds in the breeding ponds; and the number of fishes, krill and trionyxin the breeding ponds is counted. Overgrown aquatic animals are caught, symbiotic breeding of fishes, krill and trionyx can be achieved, the krill can be induced to enter the other two breeding netsby spraying an inducer through the breeding nets, the fishes and the trionyx are periodically driven to penetrate through an isolation dam to count the fishes and krill, the excessive fishes and trionyx are selectively fished, and therefore ecological balance in the breeding ponds is achieved.

Description

technical field [0001] The invention relates to the technical field of cultivation, and more specifically relates to a cultivation method for symbiosis of rice, fish, turtle and shrimp. Background technique [0002] At present, the rice-fish-duck symbiosis system is a long-term developing agricultural ecosystem in southern China, and its main feature is fish farming in rice fields. In some places, a rice-fish symbiosis system was developed. Before and after the Grain Rains, farmers inserted the seedlings into the rice fields, and the fish fry were also put in and raised in the rice fields. The activities of the fish have the functions of weeding, loosening the soil, preserving fertilizer and fertilizing the rice. , Promote fertilizer decomposition, benefit rice tillering and root development, and control pests and diseases. Raising fish on the surface of rice fields can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, t...

AI Technical Summary

Problems solved by technology

[0003] At present, the mode of paddy field farming is gradually developing from a single aquatic product to a multi-aquatic product co-cultivation mode. The effect of this is to increase the economic income of the paddy field; however, there are still many insurmountable problems in the co-culture mode, such as water The prevention and control of product diseases, the reasonable arrangement of the stocking time of different aquatic product seedlings and the harvesting time of aquatic products, the reasonable setting of the stocking density, etc. a common trend

However, there is currently no breeding method for the symbiosis of rice, fish, shrimp and soft-shelled turtles
