A Cylindrical Oviposition Attachment Base of Pseudomonas laiburi

Abstract

The invention provides a Bigfin reef squid cylindrical spawning adhering substrate, and belongs to the field of aquaculture. The Bigfin reef squid cylindrical spawning adhering substrate includes a base and an adhering substrate body; the adhering substrate body includes a plurality of adhering substrate monomers which are vertically sleeved with each other; the adhering substrate monomers can befreely inserted into the adhering substrate base; the adhering substrate monomers are of hollow cylindrical structures; large holes, intermediate-sized holes and small holes are distributed on the adhering substrate monomers; the large holes and the intermediate-sized holes are grouped; each group of holes includes one large hole and 3-5 intermediate-sized holes; the intermediate-sized holes are evenly distributed on the intermediate-lower parts of the outer peripheries of the large holes; 3-5 groups of holes are evenly distributed on the same horizontal plane of each of the adhering substratemonomers, and 3-5 groups of holes are evenly distributed on the vertical plane; small holes preventing fertilized eggs from adhering are distributed on the rest positions of the adhering substrate body as water permeable holes. Adhering points suitable for spawning of parents are provided on the adhering substrate by controlling the diameter of the large holes and a distance between adjacent holes, and the Bigfin reef squid can lay eggs on the plurality of adjacent holes, and then the problem of sparse eggs during hatching can be avoided.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a cylindrical egg-laying attachment base of Pseudomonas laiburi. Background technique [0002] Sepioteuthis lessoniana Lesson, English name: Bigfin reef squid, Japanese name: アオリイカ, belongs to Mollusca, Cephalopoda, Coleoidea, Teuthida , Myopsida, Loliginidae, Sepioteuthis, is a large squid, mainly distributed in southern Fujian and the coastal areas of Guangdong, Japan Islands, Hawaii Islands, Malay Islands, Offshore India and the Red Sea are also distributed. There are 7 known species of Pseudomonas genus, and there is only 1 species of Pseudomonas reinhardt in my country. Squid is a major economic cephalopod in the warm water area of ​​the western Pacific Ocean. It is often caught in the coastal waters of Guangdong and southern Fujian in China. The annual output is about 200t. The edible part is high, the meat is tender and delicious, and it is a good seafood after dry...

Problems solved by technology

However, due to the strict selection of attachments by the broodstock, they prefer to lay their eggs in the same place. The thickness and spacing of the egg laying site can affect the amount of attached eggs, which often results in excessive egg laying at the site suitable for attaching eggs, and fertilized eggs in the later stage of hatching After swelling, it is not easy to permeate water, causing a large number of fertilized eggs to rot
