Description

Oak artificial fish-reef for sea cucumber and abalones}

The present invention relates to an oak reef for sea cucumber abalone, and more particularly, to an oak reef exclusive for sea cucumber abalone in which oak units are stacked in multiple stages so as to be suitable for habitat of sea cucumber and abalone.

Not only herbivorous crustaceans such as abalone and conch, as well as echinoderms such as sea urchins are nocturnal shellfish that feed on algae and diatoms, so at night they eat algae and diatoms while working on relatively flat ground, such as bedrock, gravel, and sand. When it occurs, it has a habit of rest or hiding in the unevenness or curve of the rock mass. In addition, sea cucumbers, a kind of echinoderm, mainly inhabit at a depth of 10 to 20m, and when the water temperature rises above 20℃, they enter the deep sea or dig deeper into the seabed and sleep in the summer. It has habits and feeds on organic floats (seaweed fragments, fish and shellfish debris, pens, etc.) floating on algae in seawater, and it also lives by ingesting thin deposits on the surface of the seafloor.

An artificial structure installed on the seabed as a fishery facility to protect and nurture fish, as well as crustaceans and echinoderms, is a fish reef dedicated to sea cucumber abalone. These sea cucumber abalone fish reefs become a habitat for seaweeds that play a large role in the marine ecosystem, and abundant seaweeds become food for fry and shellfish, making them a good spawning ground for fish. In addition, the fish reef dedicated to sea cucumber abalone blocks strong waves and ocean currents, creates eddy currents, and provides abundant dissolved oxygen and fine plankton, making it an excellent resting place for fish and shellfish.

There are various types of fish reefs for sea cucumber abalone according to each purpose, but extracts from them will be briefly described.
