Embodiment Construction

[0007] 1. Choose polyethylene corrugated board as the attachment base

[0008] When the larvae develop to the end stage of big-eared larvae or bottle-shaped larvae, polyethylene corrugated board (length×width: 100×150mm), screen (length×width: 200×300mm) and polyethylene film (length×width: 100×300mm) and polyethylene film (length×width: 40×300mm) as the attachment base. Before use, soak the above three attachment bases in seawater respectively, and then use concentration (5-10)×10 -4 Soak in potassium permanganate solution, then rinse with water and dry. After 5 days, the number of larvae attached to each attachment base was counted, and the metamorphic attachment rate of larvae was calculated.

[0009] The results showed that among the above three different adhesion bases, the abnormal adhesion rate of polyethylene corrugated board was the highest at 29.3%, followed by polyethylene film at 18.4%, and the lowest at 14.7% for screen. Using polyethylene corrugated board as t...

Abstract

The invention relates to an attachment base processing method for improving abnormal attachment of stichoposide seeds, which is characterized by comprising the following steps: selecting a polyethylene corrugated plate as an attachment base; then, processing the attachment base by a biological film containing diatom, or soaking the attachment base in the adult tissue extracting solution; and finally, cultivating stichoposide seeds. Based on the feasibility of actual seed production of stichoposide, the invention can obviously improve the abnormal attachment rate of pelagic larvae and the rateof emergence by selecting the proper attachment base and simply processing the attachment base under the condition that the production cost and the manual work are not increased greatly.

Description

technical field [0001] The invention relates to an attachment base treatment method for improving the metamorphic attachment of sea cucumber seedlings. Background technique [0002] Sea cucumber is the crown of "Eight Treasures of Seafood". It is naturally distributed in East Asia of China, Japan and South Korea. It is an important marine economic animal in my country. Over the past 10 years, with the depletion of global sea cucumber natural resources and the continuous growth of domestic sea cucumber consumption, sea cucumber farming in my country has shown a rapid development trend. According to statistics, from 2003 to 2006, the average annual growth rate of production was 12.2%, which was higher than the national average annual growth rate of 5.6% in the same period. Among them, the total output of sea cucumbers in 2006 was about 75,700 tons, and the breeding area reached 84,200 hectares. At present, sea cucumber farming has become a farming industry with local charact...
