Embodiment 1
[0018] 1. Formula: 25 kg of white fish meal, 10 kg of shrimp meal, 6 kg of squid meal, 6.5 kg of sargassum powder, 10 kg of sargassum powder, 22 kg of soybean meal, 15.45 kg of flour, 3 kg of fish oil, 1 kg of soybean lecithin, 0.5 kg of compound mineral salt, 0.5 kg of multivitamin and 0.05 kg of ethoxyquinoline.
[0019] 2. Preparation method: crush the above-mentioned solid feed raw material components through a 250-mesh sieve, mix the pulverized raw materials evenly with a stepwise dilution method, and then mix them evenly with the two liquid raw materials of soybean lecithin and fish oil, add appropriate amount of water Mix evenly, then granulate with a twin-screw granulator, dry at 50°C, then crush, sieve, and classify to make micro-granule feed.
[0020] 3. Breeding results: use the artificial micro-granule feed of this embodiment to feed the larvae of the gridworm (specification 25000 heads / jin or so). Every day by 5-10% of juvenile body weight, the microparticle feed...

Abstract
The invention discloses an artificial micro-diet for naiads and larvae of Sipunculus nudus. At present, a research and development technology for an artificial feed for the naiads and larvae of the Sipunculus nudus is still blank, and a self-cultured biological bait which can be used for the intermediate rearing of the naiads and larvae of the Sipunculus nudus hardly meets the demand of mass seedling production due to unstable supply, so that the problems that the survival rate of artificial breeding is low, the yield of seedlings is low, the breeding scale is difficult to expand and the like are caused. In the invention, aiming at the digestive physiological characteristics of the Sipunculus nudus at nymphal and larval phases, the artificial micro-diet is prepared by selecting feed raw materials with high utilization rate. Nutrient components contained in the artificial micro-diet can meet the need of fast growth of the naiads and larvae of the Sipunculus nudus; the artificial micro-diet improves the survival rate of the seedlings of the naiads and larvae of the Sipunculus nudus and the digestibility of various nutrients by the naiads and larvae of the Sipunculus nudus; the artificial micro-diet has the advantages that: the excretion of nitrogen and phosphorus is reduced, the stability is high, the dissolution rate is low, and the artificial micro-diet slightly pollutes water bodies; and the problem that a biological bait is inadequate during the artificial breeding of the Sipunculus nudus is solved.
Description
technical field [0001] The present invention relates to an artificial micro-particle feed for larvae larvae, specifically a kind of artificial feed that can fully meet the nutrition requirements for the growth of larvae, and solves the problem during the period of artificial seedling cultivation of phalaenopsis. The problem of insufficient biological bait belongs to the technical field of aquaculture feed. Background technique [0002] Sipunculus nudus, also known as naked square starworm, has a long cylindrical body with a body length of about 10-20cm, and the body wall forms a square lattice pattern, commonly known as "sandworm", belonging to the phylum of star insects. Common species, belonging to Sipunculidea, Sipunculiformes, Sipunculidae, Sipunculus, widely distributed in warm water world, my country Shandong, Fujian, Guangdong, Guangxi and the coastal areas of Taiwan are all distributed, among which the sea area of Guangxi is rich in resources. [0003] The square s...
