How to build marine pasture

The construction of marine pasture needs the construction of ecological environment, the cultivation and domestication of pasture organisms and the construction of supporting supervision system.

1, ecological environment construction

If you want to build a marine pasture, the first thing you need to build is the ecological environment. Only pastures with good ecological environment can ensure the healthy growth of released marine life. Artificial reef is the most commonly used way to construct the ecological environment of marine pasture. According to the use of marine pasture, suitable artificial reefs can be selected and put into pasture.

Artificial reefs can play the role of flow field effect, improve the law of material exchange in each water layer, bring nutrients deposited on the seabed to the upper water layer, provide food for cultured organisms, and provide growth substrates for algae and shellfish. In addition to artificial reefs, it is also necessary to build seaweed farms in pastures to provide oxygen for pastures and food for some fish.

2. Biological cultivation and domestication of pasture

After constructing a good ecological environment of marine pasture, pasture creatures can be cultivated and domesticated. When raising seedlings, the combination of artificial seedling raising and natural seedling raising is usually used to screen out healthy and high-quality seedlings for delivery. Then, through some domestication methods, such as regular feeding, regular playback of underwater speakers, and regular light control of breeding, the creatures in the pasture are domesticated, and the habit domestication of the target species is gradually realized.

3. Construction of supporting supervision system

In order to ensure the smooth operation of the pasture, it also needs the support of the supervision system. Through the construction of intelligent marine pasture management system and supporting hardware facilities, the functions of real-time monitoring of water quality indicators, real-time monitoring of underwater conditions, safety protection of marine pastures, statistical analysis of biological resources and so on can be realized to ensure the safety and stability of pastures.

Brief introduction to classification of marine pasture

1, fishery culture marine pasture

The most common marine pastures are usually built on the offshore coast. The output of fishery and aquaculture marine pasture is mainly marine treasures such as sea cucumber, abalone, sea urchin and swimming crab.

2. Ecological restoration of marine pasture

This kind of marine pasture mainly produces fish. Ecological restoration marine pasture belongs to the direction of encouraging development of marine pasture. Small and medium-sized ecological restoration marine pastures in northern China are mainly offshore, and there are also many large and medium-sized ecological restoration marine pastures in southern China.

3. Leisure and sightseeing of marine pasture. With the rise of leisure fishery, it is embedded in other types of marine pastures, and it is a new industry in the management and development of marine pastures.

4. Marine pasture protected by germplasm. Most of them are invested by scientific research institutions or large fishing companies, and their main functions are the conservation of marine treasures and fish resources along the offshore coast.
