Sea cucumber net cage ecological culturing technology

Abstract

The invention relates to a sea cucumber net cage ecological culturing technology which is characterized in that the technology comprises a method comprising the steps of net cage manufacturing, sea area selection, net cage colonization, sea cucumber fry selection and acclimatization, bait feed formulation, and semi-enclosed habitat preparation. According to the invention, (1) the specification of the net cage should be 3m*4-6m*9m; two layers of nets are arranged in the net cage; the specification of the net on the outer layer is 0.3-0.6 mesh, and the specification of the net on the inner layer is 80 mesh; newly purchased materials should be soaked with seawater for 10-15 days; (2) a wind-sheltering sea area with gentle currents is selected; (3) the net cages are colonized at a place where 20-30cm of the net cages are exposed above the water level; (4) sea cucumber fries are first disinfected and cooled in a storehouse; when the temperature is consistent with the water temperature at a depth of 10m at the stocking sea area for 3 days, the sea cucumber fries are put in the sea, wherein usually 1000-3000 fries are put in one net cage; (5) fresh seaweeds are harvested and crushed, and is used for quantitative feeding; (6) soaked net bags are used for making attachment devices according to a specification of 0.7 square meters per square meter of water per cage.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a sea cucumber net cage ecological breeding technology. Background technique [0002] As a precious sea treasure, sea cucumber is listed as one of the "Eight Treasures" of the sea. It is a high-end health-care nutritional food with great nourishing value, which determines its high price. "Sea cucumber, some people call it "sea ginseng".

Among them, plum ginseng and sea cucumber are the most valuable in the world. Species. Sea cucumbers and light ginseng are mostly used for tonic. The nutritional value of sea cucumbers is relatively high, and every 100 grams of water-produced sea cucumbers contains 14.9 grams of protein, 0.9 grams of fat, 0.4 grams of carbohydrates, 357 mg of calcium, 12 mg of phosphorus, and 2.4 mg of iron , ...

Problems solved by technology

What's more serious is that chemical substances such as antibiotics and auxin that have been used in large quantities for a long time are deposited in the body of sea cucumbers, and sea cucumbers themselves do not have the ability to detoxify chemical substances, and the harmful chemical substances absorbed into the body cannot be excreted from the body, and such sea cucumbers are After people eat it, not only cannot fully achieve the effect of nourishing and nourishing, but also cause harm to the human body due to the harmful substances inhaled in the ginseng.
