Kelp type hard granular feed for sea cucumber farming

Abstract

The invention discloses a kelp type hard granular feed for sea cucumber farming. The kelp type hard granular feed for sea cucumber farming is prepared from, by weight, 20-30 parts of kelp powder, 10-14 parts of wheat starch, 6-8 parts of eggs, 20-24 parts of opossum shrimps, 1-3 parts of tromethamine, 16-20 parts of corn flour, 10-12 parts of 300 mesh zeolite powder, 0.1-0.3 parts of composite poly-vitamins, 0.1-0.3 parts of composite poly-minerals, and 1-3 parts of pullulan. The kelp type hard granular feed for sea cucumber farming has the advantages of complete nutrient components, balanced matching of all components, and facilitation of the balanced digestion, the absorption and the growth conversion of sea cucumbers.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a hard granular feed for cultivating kelp-type sea cucumbers. Background technique [0002] Sea cucumber is as famous as ginseng, bird's nest and shark's fin, and is one of the eight treasures in the world. Sea cucumber is not only a precious food, but also a valuable medicinal material. Sea cucumber is the imitation sea cucumber, also known as sea cucumber, which belongs to the benthos Echinodermata, sea cucumber class, and sea cucumber genus, and has strong regeneration ability. Survival in the natural environment mainly depends on feeding on single-celled algae, benthic diatoms, organic debris, organic matter mixed in the sediment, beneficial bacteria, and small animal carcasses. When preying, it uses tentacles to swallow the sediment together. [0003] Since the success of artificial propagation technology in the 1980s, sea cucumber aquaculture has now developed into an import...

Problems solved by technology

Due to the rapid development of aquaculture scale, lagging aquaculture technology, and relatively high stocking density in pond aquaculture, natural biological bait is far from meeting the needs of its growth. Therefore, sea cucumbers grow slowly when no bait is fed for a long time in pond aquaculture.

Even if feeding algae meal, fish meal, scallops and other feed can play a certain growth-promoting effect, but due to the confusion of the feed formula, the unbalanced nutritional structure of the feed raw materials, and the lack of full-price nutrition, it will bring some nutrition to sea cucumbers. At the same time, it caused a lot of bottom pollution. During the breeding process, a series of problems such as seed quality degradation, slow growth, poor stress resistance, and frequent disease occurred, causing huge economic losses to the breeding enterprises.
