Embodiment 1

[0028] The experiment was carried out in a breeding company in Yantai, Shandong Province in April 2012. The experimental container was an ordinary seedling cement pond, and the size of the cultivation pond was 2m 3 . The invented equipment is placed at the bottom of the cultivation pool, and the air-filled pipe is externally connected with a high-pressure Roche blower, and the air pressure is 0.1-0.3MPa. The corrugated device of the inventive equipment is made of polypropylene as the matrix material, and has the characteristics of salt resistance and corrosion resistance. There are two sets of inflatable tubes under the corrugated device panel, and the inflatable device group at the peak of the corrugated device is composed of a wave peak main pipe 2, a wave branch branch pipe 3, a wave peak main switch 5, and a nano-enriched oxygen head 4, wherein the nano-enhanced oxygen head 4 has an aperture size of 15 μm. The inflation device group at the trough of the corrugated device...

Embodiment 2

[0037] The experiment was carried out in Fujian Ningde Breeding Base in June 2013. The experimental container was an ordinary seedling cement pond, and the size of the cultivation pond was 4m 3 . The experiment is divided into two groups, one is the atomization method group based on the suspending bait, and the other is the ordinary experimental group. The invention equipment is placed at the bottom of the cultivation pool based on the atomization method group of the suspension matching bait, and the inflatable pipe is externally connected with a high-pressure Roche blower. There are two sets of inflatable tubes under the corrugated device panel, and the inflatable device group at the peak of the corrugated device is composed of a wave peak main pipe 2, a wave branch branch pipe 3, a wave peak main switch 5, and a nano-enriched oxygen head 4, wherein the nano-enhanced oxygen head 4 has an aperture size of 15 μm. The inflation device group at the trough of the corrugated devi...

Abstract

The invention provides a method for breeding atomization-type octopus vulgaris pelagic period larva. Large bubbles are generated at the bottom of a breeding container; small and dense bubbles are generated along the periphery of the breeding container; and released bait can be blown from the bottom to the upper layer of the water body by the bubbles generated at the bottom. The invention establishes a method for breeding atomization-type octopus vulgaris pelagic period larva based on suspending composite bait; the mechanical damage on planktonic larva swimming along and adhered to the wall can be avoided by the aerial fog formed by nanometer aeration head of wall circulating gas tube; the composite bait falling around the nanometer aeration head is inflated to be eaten by the octopus vulgaris larva again. By means of the method, the bait composite and feeding density are also optimized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an atomization method for cultivating planktonic octopus larvae. technical background [0002] The true octopus (Octopus vulgaris) belongs to the phylum Molluscs, the class Cephalopoda, the order Octopus, the family Octopus, and the genus Octopus. In my country, the true octopus is mainly distributed in the southeast coastal waters. According to the statistics of the World Food and Agriculture Organization (FAO, 2010), the catch of cephalopods in the world is 4.3 million tons, of which true octopuses account for 50% of octopuses. [0003] As an economic species with great breeding potential and development prospects, octopus has the advantages of fast growth, short breeding cycle and high nutritional value. At present, more than a dozen countries including Spain, Chile, and Mexico have successively carried out research on the breeding and breeding of octopus see...
