Sea urchin is a miscellaneous and benign marine animal. The proliferation of sea urchin has consumed algal resources in the breeding area to a certain extent, destroyed the original ecological system, and provided sufficient feed for the sea urchin in the bottom broadcast area. Ecological maintenance of the broadcast area must be carried out, so it is necessary to apply artificially-produced food to the broadcast area.
The type of breeding bait is based on the natural conditions of the broadcast area and the species that the sea urchin prefers. In general, seaweed, wakame, and other brown algae that are preferred by sea urchin are the main varieties of multiplication because of these varieties. Strong adaptability and rapid growth.
The method of proliferation of bait is the method of planting the rope. This method is to raise the entire rope kelp of cultivation, and use the stone as the sinking in the bottom broadcast area, sinking and laying on the sea floor. This method is costly and inconvenient, but it can Directly increase the ready-to-see area for ready-to-eat bait, and spores adhere to rocky reefs at suitable timing (spores of seaweed spores) for secondary growth. Another method is to attach spores to stones and wait for their development and growth to the seedlings. During the period, it was placed in the near-shore reef area of ​​the broadcast area, which allowed it to grow under its own conditions and become the food of the sea urchin.
