The invention discloses a low-carbon and environment-friendly fish-farming method. The method comprises the following steps: (1) performing cage culture in a pond and assembling a fish feces recovery system and a translation bottom sewage self-leaking system under a cage to recover fish feces, so that sewage and deposits at the bottom of the pond are discharged effectively, and pollution of fish feces and residual feeds on a water body is lowered; (2) arranging aeration equipment outside a cage culture zone to promote flow of the upper, lower and surface layers of the water body and increase dissolved oxygen of the water body; (3) planting aquatic plants in a floating bed and combining pond culture and wet land planting and culture outside the cage so as to realize coexistence of fishes and vegetables and biologically purify water; (4) performing scientific fish culture by adopting a scientific culture mode represented by seven words, namely, water, planting, feed, prevention, separation, mixing and labor. According to the low-carbon and environment-friendly fish-farming method, the current-stage pond fish culture facility is changed, engineering of innovative culture equipment is realized, scientific design and scientific layout are achieved, scientific combination of comprehensive technologies such as physical and biological purification and the like is performed, combination with an ecological and environment-friendly culture technology is realized, and integrated innovation is implemented.

The invention relates to a multi-hierarchy ecological fish culturing method based on utilization of hot spring swimming pool waste water. A multi-hierarchy ecological treatment system based on the utilization of hot spring swimming pool waste water is constructed. The multi-hierarchy ecological treatment system comprises three parts: a hot spring swimming pool part, a swimming pool waste water ecological treatment part and a fish culturing part, wherein the swimming pool waste water ecological treatment part is a narrow and circuitous ecological treatment channel by which a drainage channel ofthe swimming pool waste water is set so that a volume is 5-10 times greater than a daily water discharge of a swimming pool, and divided to two sections. The first-section ecological treatment channel is a sand oil tunnel directly excavated on the ground, two walls and bottom are treated by hardening treatment, and spiral seaweeds are put into the water; and the second-section ecological treatment channel is a sand oil tunnel directly excavated on the ground, two walls and bottom are not treated by the hardening treatment, aquatic plants are planted, and river prawns, freshwater mussels and rhodeus ocellatus are put. Through a technical scheme of the multi-hierarchy ecological fish culturing method, while the hot spring swimming pool waste water reaches the fish culturing part, water quality of the waste water is harmless to fishes, and fish culture can be performed in various modes according to the need.

The invention provides an ecological rice eel planting and breeding method for preventing and controlling insect pests by water logging in fields and ponds. The method comprises the following steps: constructing dikes in a rice field to arrange fish pits and fish ditches; splashing quick lime in the whole rice field to sterilize and improve soil during turning of the rice field, and carrying out innocent treatment on weeds; breeding cyprinoids, grass carps, hemiculterleucisculus and eels; sowing rice in different boxes; and preventing plant diseases and insect pests by using a water logging method and spraying limb water. The weeds are removed by fishes to create a good environment for rice, non-effective tillering guarantee is controlled, effective tillering of nutrition supply of plantsis implemented, organic fertilizers are produced to ensure required nutrition for rice, insects are hunted to replace insect killing with pesticide, wounded, sick and disabled eels are eliminated, fish diseases are reduced, the economic benefit is increased, excrements of fishes are absorbed by rice to regulate water quality, a comfortable and cool growth environment is created for fishes, quick lime is added to sterilize, insects are prevented and controlled for fishes by water logging, the rice field is changed into an ecological environment for recycling, pesticide is eliminated, productionof ecological agricultural products is ensured, the method is dual-purpose in a place, and the economic benefit and the ecological benefit are obvious.

The invention discloses a preparation method of a coloring adjunct for aquarium fish, and belongs to the technical field of feed additives for the aquarium fish. The coloring adjunct prepared by the preparation method comprises the following raw materials in parts by weight: 0.3-0.5 part of citrus peel, 3-5 parts of silkworm excrement, 0.1-0.3 part of taurine, 0.1-0.3 part of methionine, 3-5 parts of tapioca, 1-2 parts of blood powder, 2-3 parts of cyanobacteria powder, 2-3 parts of chlorella powder, 1-2 parts of alfalfa powder, 5-8 parts of red yeast rice powder, 2-3 parts of chitin and 7-10 parts of color enhancing fluid. The coloring adjunct for aquarium fish is prepared through the following steps of mixing the raw materials, performing granulation and performing packaging. The coloring adjunct disclosed by the invention is small in dosage, quick in color enhancement and good in color enhancement effects, vats are not dyed, and besides, the health of the aquarium fish can also be guaranteed.

The invention discloses a control method for aquaculture and a controller. The control method comprises that the controller obtains the actual dissolved oxygen concentration information of a culture pond, and the actual dissolved oxygen concentration information is compared with the preset dissolved oxygen concentration information of the controller; the controller sends out an oxygen supply command to an oxygenation executive component if the actual dissolved oxygen concentration value is smaller than the setting range of the preset dissolved oxygen concentration information, and the oxygenation executive component adds oxygen to the culture pond; the controller sends out an oxygen stop command to the oxygenation executive component if the actual dissolved oxygen concentration value is larger than or within the setting range of the preset dissolved oxygen concentration information, and the oxygenation executive component stop adding oxygen to the culture pond. The control method for the aquaculture and the controller can control the culture pond accurately, the control effect is good, and human cost is reduced.
