Embodiment 1

[0020] A method for cultivating sea cucumber larvae, comprising the steps of:

[0021] Firstly, sea cucumber seedlings and larvae are cultivated: the water temperature for the larvae cultivation is 20-27°C, preferably 22-25°C, the initial cultivation density is less than 1 / ml and greater than 3 / ml, and 1 / 3 For the seawater of the volumetric amount of the cultivation pond, fresh seawater of 1 / 6 of the volume of the cultivation pond is added every day from the first day of feeding until the cultivation pond is filled up.

[0022] When the larval embryos develop into small ear-shaped larvae and the digestive tract is fully developed, they start to feed Nannochloropsis dry powder, yeast, and the mixed liquid feed of EM bacteria, and gradually turn into sarcophagus at the end of the 5th day after feeding. On the 8th day of feeding, the culture of sea cucumber larvae was over, and the culture stage of juvenile ginseng was entered.

[0023] The feeding amount on the first day is: th...

Abstract

The invention discloses a method for cultivating sea cucumber larvae. The method includes steps of distributing sea cucumber fries and cultivating the larvae; feeding mixed liquid fodder containing simulated fine nannochloris oculata dry powder, yeast and EM (effective microorganisms) to the larvae after larva embryos are developed into the small auricularia larvae and the digestive tracts of the small auricularia larvae are completely developed; enabling the auricularia larvae to start to be gradually developed into doliolarias at the end of the fifth feeding day; completing sea cucumber larva cultivation after the eighth feeding day; starting a juvenile sea cucumber cultivating stage. Compared with the traditional method for cultivating sea cucumber larvae, the method for cultivating the sea cucumber larvae has the advantages that the method is simple and convenient, fodder cultivating workshops can be omitted, labor and materials can be saved, the production cost can be reduced, and the fodder can be stably supplied, is safe and is comprehensively nutritional.

Description

technical field [0001] The invention relates to a method for cultivating sea cucumbers, in particular to a method for cultivating sea cucumber auricularia. Background technique [0002] The traditional bait for sea cucumber seedlings is microalgae such as Chaetoceros, Salina, Nitzschia, but the production of bait microalgae takes up production equipment, material resources, manpower, and high cost, and it also has certain risks, especially in continuous rainy conditions. Today, microalgae bait is not easy to grow. Once the bait is not available, it will cause great losses to the seedlings. Existing nursery technology majority uses dry yeast as the bait of sea cucumber auricularia. Compared with microalgae, dry yeast has a certain gap in nutrient composition, and some experiments reported in the past using Nannochloropsis to cultivate sea cucumber larvae did not obtain ideal experimental results. Contents of the invention [0003] The technical problem to be solved by the...
