Description

A kind of artificial fish reef with comprehensive cultivation

technical field

The invention relates to the technical field of artificial fish reefs, in particular to a comprehensive cultivation artificial fish reef.

Background technique

According to the biological learning of fish, fish often need different habitat spaces in different life stages from fish eggs to adult fish. The vast majority of rocky reef and offshore migratory fish need to find attachment bases for their spawning in algae fields along the coast. After the fish eggs hatch, the fish gradually transition from the algae field to the rocky reef area and the artificial reef area, and then live there or start migrating. At present, the algae field resources in the coastal intertidal zone of our country are seriously degraded. Although we have invested a large number of stone reefs and concrete component reefs, their main purpose is to multiply bottom-sowed aquatic economic animals. Taking the bottom-sowing multiplication marine ranch as an example, most of the multiplied species are single species such as sea cucumbers or shellfish, and the habitat space is the seabed. Moreover, the population structure of the biological community constructed by this type of marine ranch is relatively simple, which can easily lead to dominant populations. The relative richness is too high. When environmental elements change, it is very easy to break out as the death disaster of the multiplied species caused by hypoxia. In addition, due to the increased turbidity of seawater due to the development of offshore coastal zones, the algae attached to the bottom fish reefs cannot receive sufficient irradiation, which makes the growth of individual algae and the proliferation of algae fields gradually more difficult.

In the construction of artificial reef areas in my country at the present stage, stone reefs, small concrete component reefs, and shipwreck reefs are mainly used. For the biological communities formed by stone reefs and small concrete component reefs, sea cucumber multiplication, algae attachment, and juvenile fish aggregation are the main species. For large structural reefs such as shipwreck reefs, adult fish are mainly gathered. This also makes the fish eggs face great pressure for survival when they transition to the artificial fish reef area of the rock reef area or large-scale structural reef after hatching from the algae farm to become larvae. Therefore, it is very necessary to provide a living space for fish in the juvenile stage during the growth process from larvae to adult fish.

To sum up, the habitats of juvenile fish resources in artificial reef areas can be improved by bringing together species in different habitat spaces, based on the differences in biological learning between species, and relying on the complementary ecological advantages of species. The number of sources of adult fish can realize the comprehensive cultivation of multiple species. This will be the development trend of artificial reef design in the future.

Therefore, how to provide an artificial reef for comprehensive cultivation of rocky and migratory fish juveniles, oysters, sea cucumbers, etc. is an urgent problem to be solved by those skilled in the art.
