Abstract

The invention discloses a granular compound feed for the intermediate culture of sipunculus nudus. The feed comprises the following ingredients by weight percent: 32-40% of white fish meal, 5-11% of bean pulp, 4-8% of peanut meal, 6-10% of sargassum powder, 4-8% of shrimp shell meal, 2-5% of squid liver powder, 2-5% of beer yeast, 18-22% of flour, 2-4% of zeolite powder, 2-4% of fish oil, 0.5-2% of soya bean lecithin, 0.5-1% of composite mineral salt, 0.5-1% of composite vitamin and 0.05-0.08% of ethoxyquin. The nutritional ingredients in the feed disclosed by the invention can meet fast growth demand of the sipunculus nudus in an intermediate culture stage; the feed is good in stability in water, low in dissolution rate, small in pollution on a water body, good in palatability, and high in conversion rate; the particle size of the feed is suitable for the mouth diameter of the sipunculus nudus in the intermediate culture stage; the raw materials are reliable in resources and low in cost; and the preparation process is simple. When the feed disclosed by the invention is applied to feeding the sipunculus nudus in the intermediate culture stage, survival rate is high, growth speed is fast, the intermediate culture time of the sipunculus nudus is shortened, and the artificial breeding efficiency and the breeding production efficiency of the sipunculus nudus are improved.

Description

A kind of Sipunculus nudus intermediate rearing granular mixed feed

Technical field

A kind of Sipunculus nudus intermediate rearing granular mixed feed that the present invention relates to is a kind of granular mixed feed that can satisfy Sipunculus nudus growth desired nutritional during the intermediate rearing fully specifically, belongs to technical field of aquaculture feedstuff.

Background technology

Sipunculus nudus is commonly called as " sandworm ", is one of famous precious marine product kind of China, its delicious flavour, nutritious, be rich in multiple nutritional components such as protein, fat and calcium, phosphorus, iron thereby have the good reputation of " seabeach sausage ", very popular, have good market prospects.In recent years, along with the breakthrough that artificial indoor raising of seedling technology obtains, Sipunculus nudus is increasing in the coastal breed scale of south China.The intermediate rearing of Sipunculus nudus does not have special-purpose mixed feed so far, what use at present all is the feed of culturing dealer's autogamy, as: the simple proportioning of spirulina powder, prawn slice, fish meal, dregs of beans etc., technology is coarse, composition is simple, the feed of autogamy is owing to hypotrophy face, feed cause feed efficiency low in the water stability difference, and polluted water has had a strong impact on the growth of Sipunculus nudus easily, makes that the speed of growth of Sipunculus nudus is slow.Open (bulletin) number: CN102210406A, title is: the patent of invention of the artificial micro-granulated feed of the young larva of a kind of Sipunculus nudus, it is the patent that the applicant applies for, but the disclosed micro-granulated feed of this patent only is applicable to the growth of Sipunculus nudus naiad, Sipunculus nudus is in whole growth process, different growth phases provides the feed of Different Nutrition composition, just help the growth of Sipunculus nudus, could regulate the speed of growth scientifically and rationally, make the existing speed of growth faster of Sipunculus nudus, the general equilibrium that can reach the endotrophic composition again is reasonable, and meaning of the present invention just is to endeavour to solve the problem of this respect.

Summary of the invention

Purpose of the present invention just provides the granular mixed feed that a kind of Sipunculus nudus intermediate rearing is used, to satisfy the growth demand of intermediate rearing phase Sipunculus nudus.Overcome that the existing existing technology of autogamy feed is coarse, composition simple, hypotrophy face, poor stability,, the easy deficiency of polluted water.

The objective of the invention is to be achieved through the following technical solutions: a kind of Sipunculus nudus intermediate rearing granular mixed feed, mainly the feedstock production by following mass percent forms: white fish meal 32-40%, dregs of beans 5-11%, peanut meal 4-8%, sargassum powder 6-10%, shrimp shell meal 4-8%, squid powder 2-5%, brewer's yeast 2-5%, flour 18-22%, zeolite powder 2-4%, fish oil 2-4%, soybean lecithin 0.5-2%, composite mineral salt 0.5-1%, B B-complex 0.5-1% and ethoxyquinoline 0.05-0.08%.

Above-mentioned solid feed raw material components was pulverized the 150-200 mesh sieve; after raw material after pulverizing mixed with the method for stepwise dilution; mix with soybean lecithin and these two kinds of liquid charging stocks of fish oil again; add and be prepared into softwood after suitable quantity of water is mixed; granulate with granulator according to a conventional method; 40-60 ℃ of oven dry, broken then, sieve, classification makes 80-100 purpose pellet.

Described fish meal, dregs of beans, peanut meal, shrimp shell meal, squid powder and brewer's yeast all are commercially available prod, and the protein content scope of every kind of product is respectively 65-75%, 40-50%, 45-50%, 30-40%, 55-62%, 45-55%.

Described sargassum powder is the commercially available prod, and the crude protein content scope is: 13-20%; The crude fat content scope is: 0.4-1%; The coarse ash content range is: 12-20%.

Described zeolite powder is the commercially available prod that meets GB/T 21695-2008 feed grade zeolite powder standard.

Described fish oil is to meet the commercially available prod of SC/T 3504-2006 feed with the fish oil standard.

Described soybean lecithin is the commercially available prod that meets feed addictive soybean lecithin GB GB/T 23878-20092.

Described composite mineral salt and B B-complex all are commercially available special aquatic products animal composite mineral salt and B B-complex.

Described ethoxyquinoline is the feed grade raw material, and its content range is 60-66%.

Take the present invention of above-mentioned measure, the granular mixed feed of making has following characteristics: 1, various component compatibilities are reasonable, the needs that training phase Sipunculus nudus was grown fast during contained nutritional labeling can satisfy; 2, feed is good at water stability, and dissolution rate is low, and is less to water pollution; 3, feed good palatability, conversion ratio height, particle diameter adapts to the bore of intermediate rearing phase Sipunculus nudus; 4, the dietary protein level of making is 41-43%, and fat content is 7-8%; 5, reliable, the steady quality, cheap of feed its raw material source, production technology is simple, thereby has solved the feed problem during the Sipunculus nudus intermediate rearing effectively, and helps protecting breeding environment.Use the present invention's intermediate rearing phase Sipunculus nudus (about 10000/jin of specifications) of throwing something and feeding to reach the specification of emerging (about 500/jin) until it, average survival is more than 85%, and the survival rate rising 15-25% of Sipunculus nudus of autogamy feed feeds in the training pond in other than the experiment base; The speed of growth than the experiment base in other training pond feed the autogamy feed the fast 1.5-2 of Sipunculus nudus doubly, shortened the time of Sipunculus nudus intermediate rearing, improved the efficient of Sipunculus nudus artificial breeding and breeding production greatly.
