Embodiment Construction

[0010] The specific embodiment of the present invention will be described below in conjunction with accompanying drawing, as figure 1 As shown: the main reef 1 is a cube reef with a side length of 1 to 2 meters, which can be a concrete reef, and the auxiliary reef 2 is various reef types in the prior art such as smaller concrete reefs and material stone reefs. 80 to 120 cm, the number is 3 to 8, and the two types of adjacent auxiliary reefs are different, and 2 to 8 types can be selected according to needs. The main reef 1 and the auxiliary reef 2 are connected by a stone bridge 3, which is a pile of stones with a diameter of 20 to 50 centimeters and a length of 3 to 6 meters.

[0011] When launching on-site, you can use GPS settings such as figure 2 The accurate positioning shown is carried out, and the unit fish reefs 4 formed by the embodiment of the present invention are arranged at intervals of 10 to 20 meters (outer circumferences). Each reef group contains at least 40...

Abstract

The invention discloses a star-like radial allocation method for artificial reefs, which is characterized in that a cubic reef form with the side length of 1 to 2 meters is used as a main reef, 3 to 8 auxiliary reefs with the height of 80 to 120 centimeters are uniformly distributed on the circumference which uses the main reef as the central point, the main reef and each auxiliary reef are connected through a stone connection bridge with the length of 3 to 6 meters, and the categories of the adjacent auxiliary reefs are diverse. The artificial reefs are closer to the reality and are favorable for the balance of the ecological system, and the stone connection bridge serving as a radiation belt provides a bridge for the movement of rare seafood among the reefs and plays a role in sheltering. Through on-site sea area tests, the rare seafood such as sea cucumber, sea hedgehog, abalone and the like can rest in gaps among the main reef, the auxiliary reefs and the stone connection bridges or on the surfaces; the good growth condition of algae on the reefs provides baits for the rare seafood, so the proliferation effect of the rare seafood is obvious; and reef-associated fishes such as hexagrammos otakii, sebastes schlegeli and the like rest in the main reef and the auxiliary reefs, so the whole reef group structure is stable and forms a good small ecosystem.

Description

Technical field: [0001] The invention relates to a configuration method of artificial fish reefs, in particular to a star-shaped radial configuration method of artificial fish reefs which is beneficial to the habitat and growth of sea treasures (sea cucumbers, sea urchins, abalones) and rocky fishes and has good multiplication effect. Background technique: [0002] With the continuous development of sea urchin, sea cucumber, abalone and other sea treasure fisheries, their natural resources have declined significantly. Therefore, people adopt the following two methods in order to increase and restore their resources: one is to develop large-scale artificial breeding, but due to artificial breeding The quality degradation, frequent occurrence of diseases caused by high-density breeding, serious self-pollution and food safety issues all restrict the development of artificial breeding. The second is artificial proliferation and release. Artificial value-added release is to buil...
