Fish and vegetable symbiosis intelligent regulation and control system for aquaculture
Technical Field
The invention relates to the technical field of aquaculture, in particular to a fish-vegetable symbiosis intelligent regulation and control system for aquaculture.
Background
Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control; generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management, and can also comprise the multiplication of aquatic resources in a broad sense. Aquaculture has modes of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and culture aquatic products such as fish culture in lakes and reservoirs, shellfish culture in shallow sea and the like completely by using natural baits; intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density fish culture, shrimp culture and the like.
In the traditional vegetable and grain planting, chemical fertilizers and pesticides are needed for planting, so that pollution is easily caused; with the increasingly strict requirements of the country on environmental protection, the use amount of chemical fertilizers and pesticides in vegetable planting is strictly limited; meanwhile, in the aquaculture process mainly by pond fish culture, a large amount of excrement is generated by fishes, a large amount of different baits are put in artificially, and fish growth treatment medicines are put in artificially, the bait residues, chemical residues and cultured organism excreta rich in nitrogen, phosphorus, organic matters and toxic substances cause water body environment pollution, meanwhile, the eutrophication degree of cultured adjacent water areas is aggravated by the discharge of the waste water, and the discharged waste water becomes an important pollution source of the water areas in China.
In the prior art, some culturists propose a fish and vegetable symbiotic system through aquaculture, and simultaneously solve the problems of excessive fertilizer used by vegetables and pollution of fish emissions to water; however, the existing symbiotic system lacks the function of circulation regulation, and once the vegetables cannot process enough excrement, the vegetables are burnt; meanwhile, when the excrement is insufficient, the vegetable malnutrition can be caused, so that the vegetables cannot obtain enough nutrients, the aquaculture fish-vegetable symbiotic system is easy to fail, and the loss is caused, namely the pollutants in the water body are treated, and the good growth of plants such as the vegetables is not caused.
