Kelp seedling raising method for controlling diffusion of zoospores through precise counting

Abstract

The invention provides a kelp seedling raising method for controlling diffusion of zoospores through precise counting. The kelp seedling raising method comprises a kelp cultivation stage, a zoospores mother liquor preparation stage, a zoospores mother liquor distribution and zoospores attachment stage and a kelp seedling cultivation stage. According to the kelp seedling raising method for controlling the diffusion of the zoospores through precise counting, the usage amount of the seed kelp can be remarkably reduced, the chance that the seed kelp carries harmful microorganisms and miscellaneous algae to enter a seedling raising system is reduced, the production cost and the labor intensity are reduced, and the occurrence probability of diseases in the seedling stage is reduced; the kelp zoospores collection mode is improved from qualitative collection to quantitative collection, the consistency of the number of spores attached to the upstream of each seedling raising device is guaranteed, errors caused by factors such as the operation mode of technicians and microscope configuration are reduced, the operation difficulty of seedling raising is reduced, control over the seedling attachment density and cultivation of strong seedlings are facilitated, and the seedling raising efficiency is improved. Daily management during seedling culture is facilitated, and the success rate of healthy kelp seedling culture is increased.

Description

Technical field [0001] This application belongs to the field of seaweed culture technology and, more specifically, relates to a method of kelp seedling propagation controlled by precise counting of zoospores. Background [0002] Marine aquaculture seed engineering is the top priority in the development of marine agriculture, and seed is the foundation for the development of marine aquaculture. In recent years, the total output of dry kelp in China has been more than 1.6 million tons, accounting for more than 60% of the total production of algae in the country, ranking first in domestic algae production. [0003] The annual output of kelp seedlings in China is about 40 billion plants. All kelp seedlings are cultivated using the natural light summer seedling cultivation method established in the 1950s, which has undergone nearly 70 years of development and has been promoted to Liaoning, Shandong, Fujian and other regions. In the actual production, it was found that there are still...

AI Technical Summary

Problems solved by technology

For example, in the traditional method, the release method of the zoospores is divided into separate pools, so it is very easy to have the problem of unification of the maturity and release time of the zoospores in different release pools, resulting in different vigor of the released kelp and difficulty in controlling the attachment density of the nursery. Difficulties, it is also easy to bring in a large number of microorganisms and plankton to contaminate the nursery, resulting in the occurrence of seedling diseases; the use of a large number of kelp species, resulting in a waste of a large number of kelp resources, a large workload, manpower and material resources, etc.
