Efficient cultivation method for tropical juvenile holothuroidea

Abstract

The invention discloses an efficient cultivation method for tropical juvenile holothuroidea. According to the technical scheme, by setting the reasonable cultivation density, automatically and fully stirring floating water through an air pump, improving larva metamorphosis attachment efficiency through multiple methods and reasonably feeding bait without living algae, the water body is stabilized, and the invention discloses the cultivation method for the tropical juvenile holothuroidea. The efficient cultivation method has the beneficial effects that the air pump is used for automatically and fully stirring the floating water body, so that the manpower consumption is greatly reduced, and the survival rate of the floating larvae is increased more simply and more conveniently. On the premise of guaranteeing high cultivation efficiency, bait without living algae is fed, operation is simplified, energy consumption is reduced, the risk of diseases and insect pests brought into living algae is effectively prevented, the water body does not need to be replaced in the early stage, controllability is obviously enhanced, the cultivation efficiency of the tropical holothuroidea is remarkably improved, and a solid technical foundation is provided for realizing large-scale culture of tropical holothuroidea new varieties and sustainable development and utilization of tropical holothuroidea resources.

Description

Technical field: [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for efficiently cultivating tropical sea cucumber seedlings. Background technique: [0002] Sea cucumber (Holothuroidea) is one of the eight treasures in the world and has important therapeutic value. my country is the most important consumer market. However, except for Apostichopus japonicus, which has been commercially bred and cultured, the other 60 species of edible economic sea cucumbers are all obtained from the wild, and most of them are tropical species. With the development of my country's economy, the demand for tropical sea cucumbers has grown rapidly. From 1996 to 2011, the number of countries providing tropical sea cucumbers for the Chinese market has increased from 35 to 83, and more than 90% of the tropical coastline areas have provided tropical sea cucumbers to the Chinese market. Sea cucumbers, and the price of tropical sea cucumbers increased at ...

Problems solved by technology

[0004] The applicant broke through the cultivation technology of tropical sea cucumbers in the early stage (patent application: a method for artificially cultivating seedlings of sea cucumbers in small water bodies, application number: 201710967254.4), obtained a small amount of seedlings of sea cucumbers, and reported for the first time In the further practice of the development process of tropical sea cucumbers, it is found that the cultivation efficiency of tropical sea cucumber seedlings is still low. The main problems are: 1. During the cultivation period of planktonic life, it is labor-intensive to stir the water body at regular intervals. Larger (ZL201010604454.1 a method for raising sea cucumber seedlings; 201210083064.3 a new breeding method for sea cuc
