Abstract

The invention belongs to the field of feed research technology for aquaculture. The invention relates to a preparation method of mixed feed for sea cucumber culture. The invention relates to the preparation method of mixed feed for sea cucumber culture. The method is characterized in that the method comprises the following steps: (1) the mixed feed comprises the following components in percentages by weight: 20% of scallop powder, 20% of kelp powder, 54% of sea mud, 1% of mixed vitamins and inorganic salts, and 5% of yeast powder; (2) 20% of scallop powder, 20% of kelp powder, 54% of dried sea mud, 1% of mixed vitamins and inorganic salts, and 5% of yeast powder in the step (1) are taken, powder is sieved by a 60 mesh sieve, and the materials are uniformly mixed. The scallop, the kelp, the sea mud and the like which are artificially cultured are used for producing the mixed feed for the sea cucumber, so that production cost is reduced; mixed vitamins and inorganic salts and other nutrition are added, so that the mixed feed accords with growth needs of the sea cucumber, and benefits of sea cucumber culture are improved.

Description

A kind of preparation method of sea cucumber compound feed

Technical field

The invention belongs to aquaculture feed studying technological domain, the preparation method that the present invention relates to a kind of compound fodder for holothurian culture.

Background technology

Radix Morinae Bulleyanae (Apostichopusjaponicus), one of high-quality kind of Stichopus japonicus, it is distributed in Huanghai-Bohai seas bank in China.Radix Morinae Bulleyanae mainly lives in the marine site to the myriametre depth of water, the Intertidal zone, feeding method is for licking, food species is benthic diatom, Alga Sgrgassi Enerves, sargassum thunbergii and silt, organic debris etc., and can using the residual bait and feces etc. of other biological that are deposited in marine ecosystems in bottom without mineralising biodeposition as nutrient source again with.

The Gold Industry fast-growth, that scale is big, of high grade, profitable, market potential is big that apostichopus japonicus culture Ye Shi Shandong Province newly rises, the rising industry of Ye Shi China sea-farming, as the main product ground of China apostichopus japonicus culture industry, Shandong Province's Primary Construction apostichopus japonicus culture Pear dominant producing zone.But, the high-quality feed source tangleweed resource of Radix Morinae Bulleyanae eating faces exhaustion, and along with the sharply expansion of apostichopus japonicus culture scale, the macro such as sargassum thunbergii as Radix Morinae Bulleyanae high-quality feed source is gathered in a large number, and many marine sites sargassum thunbergii resource is closely exhausted.Meanwhile, market lacking high-quality and safety Radix Morinae Bulleyanae perfect compound feed, the feeding quality used by part raiser is inferior, and the mixed feed that low-quality sea mud is made often carries pathogenic bacteria.Therefore, the research and development of high-quality stichopus japonicus compound feed are imperative.

Flourish along with holothruian cultures industry, Stichopus japonicus is progressively to low medicine, low-residual development, and aquatic products are also marched toward pollution-free industry revolution gradually, and therefore, holothruian cultures industry is inevitable advances towards optimum sound development track, such as Eco-breeding pattern, industrialized aquaculture pattern etc.；Sea cucumber compound feed is also inevitable to be developed towards more environmentally-friendly, low value, efficient direction.

Summary of the invention

It is extensive that invention relates to the use of resource, the scallop of artificial cultivation cheap and easy to get and Thallus Laminariae (Thallus Eckloniae) and sea mud etc. make sea cucumber compound feed, reduce production cost and do not affect the normal growth of Stichopus japonicus, add the nutrition such as mixed vitamin inorganic salt and more meet Stichopus japonicus growth needs, improve the benefit of holothruian cultures.

1, the preparation method that the present invention relates to a kind of compound fodder for holothurian culture, it is characterised in that step is as follows:

(1) it is scallop powder 20%, Kelp Powder 20%, sea mud 54%, mixed vitamin inorganic salt 1%, yeast powder 5% by weight percentage;

(2) taking (1) scallop powder 20%, Kelp Powder 20%, dry sea mud 54%, mixed vitamin inorganic salt 1%, yeast powder 5%, powder all needed 60 mesh sieves, Homogeneous phase mixing.

According to the present invention, " % " in the present invention is percentage by weight.

Compared with the prior art the present invention, has the following characteristics that

The present invention is suitable for Stichopus japonicus naivety ginseng and becomes ginseng

1, normal growth is not affected.

2, rate of body weight gain increases substantially, and feed coefficient reduces, and phagostimulating effect is notable.

3, the cost of sea cucumber compound feed reduces.

Detailed description of the invention

The preparation method relating to a kind of aquaculture mixed feed of the present invention includes following example, and the following examples can further illustrate the present invention, but does not limit the present invention in any way.

Detailed description of the invention:

Concha Ostreae, Thallus Laminariae (Thallus Eckloniae) raw material pretreatment:

Fresh Concha Ostreae, removes impurity, cleans up, drain, dry to constant weight in 60 DEG C of baking ovens, after pulverizer is pulverized, crosses 60 mesh sieves standby.

Thallus Laminariae (Thallus Eckloniae) decocting in water is opened, and drains, and dries to constant weight in 60 DEG C of baking ovens, and it is standby that pulverizer crosses 60 mesh sieves after pulverizing.

Scallop, Thallus Laminariae (Thallus Eckloniae) can be that dry product also can use with the making beating of fresh material.

Holothurian feed formula and process:

(1) it is scallop powder 20%, Kelp Powder 20%, sea mud 54%, mixed vitamin 1%, yeast powder 5% by weight percentage;
