Technical Field
The invention relates to the technical field of aquatic organism breeding, in particular to an algae breeding device for algae eating organisms and a breeding method thereof.
Background
The sweet fish is a migratory fish which traces the river and spawns, and the sweet fish is named because the sweet fish can emit faint scent of cucumber. Spawning at the junction of salt water and fresh water in early winter every year, and continuously shrinking to die after spawning, wherein the hatched fries need to live through the winter at the junction of the salt water and the fresh water, and then trace to the river again in early summer in late spring to fatten in the fresh water; after entering fresh water, mainly scraping diatom, basket algae and other algae on rocks, and simultaneously feeding insects and zooplankton; as shown in fig. 3, the teeth of the plecoglossus altivelis are distributed on two sides of the head and are saw-toothed, and when the plecoglossus altivelis is scraped on the rock, messy scratches are left, as shown in fig. 4 and 5.
The sweetfish has high requirements on environment and water quality, often inhabits in mountain stream in shallow water and low temperature, and is fed by benthic algae attached to rocks. The resource amount is reduced sharply due to the influence of the external environment, and particularly, a large number of forests are felled at the upstream of the spawning and fattening river section of the sweetfish, the land is reclaimed, so that serious water and soil loss is caused, and the environment for the reproduction and survival of the sweetfish is damaged; in addition, almost all rivers are blocked and dammed to build a reservoir, thereby blocking mountain stream channels and changing hydrological conditions of rivers; a large amount of industrial sewage is discharged into the river, the water quality is seriously polluted, and the original ecological environment is destroyed; more serious, the production area generally has the phenomenon that a large amount of resources are seriously damaged by killing the young and the adult sweet fishes, such as poison, explosion and the like, and the sweet fishes suffer destructive damage by adopting poor fishing methods such as electricity, dense nets, cormorant and the like, so that the artificial breeding of the sweet fishes has wide scenes.
