Description

fish and vegetable symbiosis system

technical field

The utility model relates to an aquaculture system, in particular to a fish and vegetable symbiosis system.

Background technique

At present, the traditional aquaculture fish farming is an open system. With the continuous increase of the fish's food and excrement, the ammonia nitrogen in the culture water will not only increase, which requires regular discharge of waste water to replenish new water to change the water quality, which will cause Waste of water resources and pollution of the environment.

In order to solve the defects of the above-mentioned traditional farming model, the fish and vegetable symbiosis system came into being. At present, fish and vegetable symbiosis refers to an agricultural production system that can simultaneously carry out aquatic animal farming (fish, shrimp, crab, shellfish, etc.) and plant production (crops, vegetables, etc.), which is a combination of traditional fish farming and soilless cultivation technology. Through the feeding of aquaculture animals, the production of aquatic animals is realized, while the plants use the residual bait, feces and other organic and inorganic substances produced in the process of aquatic animal breeding as nutrients to grow, produce agricultural products, and at the same time purify the water quality and realize water quality. The recycling utilization not only avoids the discharge of aquaculture pollutants, but also saves water resources. According to the local climate characteristics and the growth needs of the species, it can be divided into outdoor fish and vegetable symbiosis system and indoor fish and vegetable symbiosis system. Generally, the outdoor method should be used in low-latitude areas, and the indoor method should be used in high-latitude areas. However, the existing fish and vegetable symbiosis system occupies a large area, and cannot adapt to the symbiosis of a large number of aquatic organisms and plants in a limited space.
