Description
Technical Field
The utility model relates to a fishery technical field, concretely relates to artificial three-dimensional adhesive base device for artificial breeding northeast crawfish.
Background
Northeast crawfish is the most widely known famous fresh river and ornamental crawfish in Asia freshwater crawfish, is a precious primary high-quality aquatic resource as a special native crawfish in east Asia, and occupies a niche in the market of the ornamental freshwater crawfish due to its unique crawfish shape. In recent years, the market demand of northeast crawfish has sharply increased, the price has risen to 35-250 yuan/kg, and the economic benefit is remarkable. The crawfish is widely edible, belongs to omnivorous animals, is meat food, is mainly eaten by various aquatic plants, aquatic mollusks, animal carcasses, aquatic insects, organic debris, etc., and is also eaten by crawfish individuals of the same kind. The molting frequency of northeast crawfish varies with living environment, and decreases year by year with the age of shrimp. In addition, shrimp bodies can develop stress shelling when subjected to environmental changes. After molting, the shrimp body is soft, the shell is hardened by absorbing calcium ions in water and regulating calcium gastrolith stored in the shrimp body, the shell is hardened for about 8-10h, and eating and other activities are started after the shell is hardened. Under the condition of no shelling, the weight of the northeast crayfish continuously increases, the body length after shelling increases, namely, the shrimp body length is increased in a step mode through shelling, and the body weight is continuously increased in the growth process. In the artificial breeding process, since young shrimp need to molt continuously during the whole life stage of mature shrimp, the shrimp body is soft after molting and can be easily eaten by other northeast crawfish without shelter, so as to reduce survival rate of crawfish and severely restrict the development of crawfish.
In order to avoid self-mutilation between the northeast crawfish and other crawfish after molting, an artificial substrate, artificial hole or hiding object is generally used to shield the northeast crawfish and prevent the crawfish from catching on other crawfish due to exposure in water during molting, thereby ensuring the survival rate of offspring breeding and cultivation of the northeast crawfish. However, the conventional artificial base is generally made of plastic pipe sets with fixed apertures, and as shown in fig. 9-10, as the northeast crawfish grows from a young shrimp to a mature shrimp, the plastic pipe sets with different apertures need to be replaced accordingly, which greatly increases the breeding cost of the northeast crawfish.
In summary, the plastic tube assembly type artificial adhesive base for artificially breeding northeast crawfish has the problems that the aperture of the plastic tube is fixed, the plastic tube assembly type artificial adhesive base cannot adapt to breeding of the northeast crawfish with different life stages and sizes, and the production cost is increased.
