Bait for juvenile sea cucumber in growing periodand preparation method of bait

Abstract

The invention relates to a bait for a juvenile sea cucumber in the growing period and a preparation method of the bait. The bait is prepared from the following components in weight percentage: 60% of sargassumthunbergii powder, 10% of common mussel meat powder, 4% of soybean meal, 6% of defatted fish meal, 2% of spirulina powder, 1.5% of baker's yeast powder, 0.5% of compounded mineral substance, 0.5% of multivitamin powder, 1.5% of immune polysaccharides and 14% of dry sea mud powder. In the bait for the juvenile sea cucumber in the growing period, the components are in mutualcompatibility, the contained nutritional ingredients can meet the rapid growing need of the juvenile sea cucumber, the juvenile sea cucumber then grows fast in the opening stage and grows to 2 mm from 0.5 mm averagely after being fed with the bait for 20 days, and the rate of survival is up to more than 80%.

Description

technical field [0001] The invention relates to the technical field of seawater aquaculture, in particular to a juvenile ginseng bait in the opening growth period and a preparation method thereof. In sea cucumber nursery, within 20 days after the metamorphosis of planktonic larvae into juvenile ginseng, the bait fed is called juvenile ginseng opening bait. Background technique [0002] Apostichopus seedlings are a pillar industry in northern seawater seedlings. With the continuous expansion of sea cucumber breeding scale, the demand for sea cucumber seedlings is increasing rapidly. In the cultivation of sea cucumber seedlings, the planktonic larvae of sea cucumber seedlings are fed with single-celled algae and baker’s yeast, which are nutritious and easy to digest; after the metamorphosis of sea cucumber seedlings from planktonic larvae to immature ginseng, the feeding habits of sea cucumber seedlings also change from predation in water to licking from attachment bases .
