Abstract
The invention provides an artificial fish reef applied to photophobic fish domestication. The artificial fish reef comprises a star-shaped body structure with a star-shaped cross section and an arc-shaped panel body, wherein the arc-shaped panel body is arranged at the outer side of the star-shaped structure, and partially covers the star-shaped structure, and the arc-shaped panel body and the star-shaped structure define one or a plurality of cavities with openings in two ends. The artificial fish reef has the characteristics that the structure is simple, the manufacturing cost is low, the mobility is good, the firmness is high, disguising spaces are many, the disguising performance is good, the water body flowing performance is good, dirt cannot be easily accumulated, and the like; a single-layer or double-layer placing mode can be adopted, a space favorable for fish to hide and avoid is formed, in addition, the operation is simple and convenient, and the artificial fish reef is applicable to various culture modes of fish pond culture, industrial aquaculture and the like, and has wide application prospects.
Description
Technical field
The invention belongs to industry fishery field, be specifically related to a kind of artificial fish shelter that can be used for the multiple aquaculture models such as fish industrial aquaculture, pond culture.
Background technology
The phototaxis of fish is behaviors and habits that fish photic stimuli produces directed movement, can be divided into photopositive and negative phototaxis, and namely tending to light source is photopositive, deviates from light source for negative phototaxis (photophobism).In the fish of the Yangtze river basin; a lot of fish in imminent danger are had all to belong to photophobism fish; as long thin loach, long Qi Wen Minnow etc.; cause its reason in imminent danger and have river pollution, hydraulic engineering construction, overfishing etc.; at present; protect the key of these species be break through its whole artificial propagation technology, but prerequisite be solve these fish in imminent danger raise and train problem.
Long thin loach, long Qi Wen Minnow raise and train in process that our find, the reaction of these fish photic stimulis is very large, if do not take measures, may cause some fish kills.And artificial fish shelter artificial arranges structure in water, improve the habitat of fish, for photophobism fish provide the space perched and hide, effectively can reduce the stress reaction that photophobism fish produce light, and throw in the breeding environment after artificial fish shelter and natural environment more close.But there is not been reported in the artificial fish shelter design of the current photophobism fish in imminent danger for the Changjiang river, therefore, current need badly a kind of structure of research and development simple, operate light, the low artificial fish shelter of cost, the stress reaction of effective minimizing photophobism fish in imminent danger at the initial stage of raising and train to light, by the survival rate that the application of this contrive equipment is raised and train to improving the Changjiang river photophobism fish in imminent danger, lay the foundation for breaking through its whole artificial propagation technology.
Summary of the invention
