Description

The present invention belongs to the technical field of fish resource propagation, and specifically relates to a resource propagation reef and a breeding method that are advantageous for fish gathering.

Freshwater bodies of water such as lakes and rivers are shallower than oceanic bodies of water, and the water conditions are clearly different, and the living habits of fish in different bodies of water are different. In addition to sensing water flow through the lateral line, fish also use their visual, auditory, olfactory, and gustatory senses, as well as the tactile senses of their cull receptors, to influence the selection of light irradiation and the color of the substrate in their habitat, and also to influence fish's burrowing habits and migration. It also affects behavioral characteristics such as habits and day/night activity rhythms. Schooling is a common behavior among fish organisms, and the behavior of fishes increases interaction and reproduction among fish, increases foraging efficiency, enhances the ability to fight against natural enemies, and reduces the probability of being predated. can be lowered. According to observations by biologists, it has been pointed out that 80% of fish have the characteristic of traveling in groups, and in particular, almost 100% of small fish have the characteristic of traveling in groups. Furthermore, it has been reported that when fish are swimming at low speed, they often follow each other as they pass each other.

For the recovery of fisheries resources in rivers and lakes, the recovery method cannot directly imitate the recovery method of marine fisheries resources, and it is necessary to make precise improvements to specific water bodies and groups of organisms. Only then can we meet the urgent need for resource recovery in freshwater bodies of water such as rivers and lakes.
