Embodiment Construction

[0027] The present invention will be further described below in conjunction with embodiment.

[0028] 1. Cultivation and Collection of Prey Organisms

[0029] 1.1 Cultivation and collection of rotifers

[0030] Rotifers are generally cultivated in fiberglass buckets with a conical bottom, and there is a drainage control valve at the bottom of the fiberglass to facilitate the timely discharge of dirty water rich in sediment. The culture water temperature is 26.5°C±2°C, the salinity is 34‰, and the dissolved oxygen is greater than 6mg / L. The rotifer culture density is controlled at 300-600 / ml. Before collecting rotifers every morning, add highly concentrated single-cell algae liquid (rich in EPA / DHA) according to the ratio of algae liquid: culture rotifer water of about 1.25ml: 1L. Coccus and Nannochloropsis, the density is about 7 million / ml). After 1 hour, take the upper layer of water rich in rotifers and filter them through a 100-mesh sieve to collect rotifers.

Abstract

The invention discloses an artificial cultivation method of red-stripe lysmata vittata larvae. The artificial cultivation method comprises following steps: collection of larvae; density and environmental requirements of larva cultivation; recirculating aquaculture prior to larval metamorphosis and cultivation of larvae. The artificial cultivation method of red-stripe lysmata vittata larvae has following beneficial effects: artificial cultivation is achieved for the first time by adoption of artificial cultivation technology so that survival rate and metamorphosis rate of zoea are greatly increased; and all of these provide quantity and quality assurance for red-stripe lysmata vittata in an aquatic market .

Description

technical field [0001] The invention relates to a method for cultivating larvae of the aquarium ornamental clean shrimp, the larvae, especially the artificial cultivation method which can greatly improve the survival rate and metamorphosis rate of the larvae under laboratory conditions. Background technique [0002] Red Whip Whip Shrimp ( Lysmatavittata ) belongs to the class Malacostraca, order Decapoda, family Hippolytidae, genus Lysmata, hermaphrodites, heterozygous fertilization. The larvae are divided into 9 different stages according to the different shapes, from the 1st stage to the 9th stage, and the moulting interval of each stage is 3-5 days. After the 9th stage, the juveniles of the red whip prawn metamorphose through moulting. It is widely distributed in the Indo-Pacific region, from East Africa to the Philippines, Australia, New Zealand, the Yellow Sea of ​​China and the eastern waters of Russia. Because of the thick and thin bright red vertical stripes on it...
