Embodiment Construction

[0027] Below by specific embodiment, method for cultivating large pinnacle juveniles of the present invention and cultivating equipment are further described:

[0028] A method for cultivating large pinnacle juveniles, comprising the following steps: Step 1: attaching seedlings, when 10% of pinnata pinnata larvae appear eye spots, put in a seedling attachment device, and attaching seedlings is completed in about 15 days. After the seedlings are completed, put a net bag on the outside of the seedling attachment, go to the sea to continue culturing, and cultivate the spat; step 2: peel off, and when the spat grows to a shell height of more than 2cm, peel the spat from the seedling attachment, and operate scissors can be used to cut off the sun-shade net strips connected by the spat silk to avoid direct pulling and reduce the damage to the spat; Step 3: transfer, put the stripped spat into the cage, and remove the spat from the attached The spats stripped from the seedlings are p...

Abstract

The invention discloses a young pinctada maxima breeding method and device. The method includes the steps of larva adhering, stripping and transferring. The breeding device comprises a piece cage and a larva adhering device which are formed by the same type of frames and simple in structure and low in cost. A vertical frame of the larva adhering device is bent outwards. In the moving process especially after a net bag is arranged in a sleeving mode, young pinctada maxima attached to the middle of the larva adhering device is well protected, and damage and falling which may be caused by collision and friction are avoided; each piece of young pinctada maxima can be effectively fixed through the piece cage, the young pinctada maxima is separated, the breeding density is decreased, the pinctada maxima survival rate is increased, the growth speed is accelerated and therefore good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of pearl cultivation, in particular to a method for cultivating juvenile oyster oyster and cultivation equipment. Background technique [0002] Pearl oyster, commonly known as white butterfly oyster, is the largest pearl oyster in my country, with a shell length of up to 32 cm and a weight of 4-5 kg. It is mainly distributed in the tropical sea areas of Australia, the Philippines, Malaysia, Indonesia and China. Pearl oyster is an important shellfish for producing large pearls. The pearls produced are the famous Nanyang pearls, each of which is as high as thousands to tens of thousands of yuan. The economic value is extremely high, and a lot of research has been carried out at home and abroad. In the early 1970s, our country obtained the success of artificial breeding of Pinctada maxima, and in the early 1980s, the success of artificial breeding of pearls was obtained. However, after 1985, a large number o...
