Description

Sea cucumber culture cages

technical field

The utility model relates to the technical field of aquaculture, in particular to a sea cucumber breeding net cage.

Background technique

Aquaculture is the productive activity of multiplying, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding management. In a broad sense, it can also include the proliferation of aquatic resources. In aquaculture, fish, shrimp, scallops, sea cucumbers, etc. are commonly cultivated.

In terms of sea cucumber culture technology, artificial reefs are usually built in the sea, and sea cucumber seedlings are placed in the artificial reefs. Usually, a large number of stones are placed on the seabed to form a pile of stones, and then sea cucumber seedlings are placed in the gaps between the stones to allow them to grow and forage there. However, if the stones are too large, the number of stones is small, and the gaps formed between them are small, so that the living space of sea cucumbers is small. If the stones are smaller, the piles of stones will spread out under the impact of rapids and storm surges, and they will be laid flat on the seabed. There is no stable gap that can block the currents. Sea cucumbers have no fixed living space and drift around with the currents, resulting in high farming income. Low. After the sea cucumber grows, divers usually dive into the bottom of the sea for fishing. Due to the limited time of each dive, the diver needs to dive repeatedly, and the number of fishing is limited each time.
