Problems solved by technology

[0003] In the current pearl oyster implantation production, the pearl oyster after operation is basically moved directly to the sea area for recuperation. Affected by the uncertainty of environmental factors such as water temperature, flow velocity, specific gravity and bait biological abundance in the sea area, The survival rate of shellfish is low, the rate of denucleation is high, the time for transplanted cell pieces to form pearl sacs is long, the secretion speed of nacre is slow, and the rate of high-quality pearls is low

Embodiment 1

[0026] A method for cultivating and recuperating in Pinctada martensii, comprising the following steps:

[0027] (1) Recreation pool selection: choose a pool with inlet and drainage facilities, a length of 100 meters, a width of 5 meters, a depth of 1.3 meters, with shading and rainproof facilities and inflatable equipment as the rest pool, and disinfected according to conventional methods before use;

[0028] (2) Preparation of seawater for recuperation: extract natural seawater from a sand filter well, the specific gravity of seawater is 1.022, filter through a fine sand layer, and then filter the shell powder made from oyster shells with a particle size of 0.25mm and a thickness of 80cm and inject into step (1) Preparation In the pool, the water depth is 1.2 meters;

[0029] (3) Selection of nucleated mother oysters: choose the pearl oysters with a shell age of 24 months, a smooth shell surface, and a correct shell shape as the nucleated mother oysters;

[0030] (4) Nuclea...

Embodiment 2

[0033] A method for cultivating and recuperating in Pinctada martensii, comprising the following steps:

[0034] (1) Recreation pool selection: Choose a pool with intake and drainage facilities, 80 meters long, 8 meters wide, 1.5 meters deep, equipped with shading and rain protection facilities and inflatable equipment as the rest pool, and disinfect it according to conventional methods before use.

[0035] (2) Preparation of seawater for recuperation: natural seawater is extracted from sand filter wells, the specific gravity of seawater is 1.018, the specific gravity of seawater is adjusted to 1.021 by adding coarse salt, filtered by fine sand layer, and then made by oyster shells with a particle size of 0.2mm and a thickness of 70cm The shell powder is filtered and poured into the pool prepared in step (1) with a water depth of 1.4 meters.

[0036] (3) Selection of nucleated mother oysters: Choose Pinctada martensii with a shell age of 20 months, smooth shell surface and cor...

Embodiment 3

[0040] A method for cultivating and recuperating in Pinctada martensii, comprising the following steps:

[0041] (1) Recreation pool selection: Choose a pool with intake and drainage facilities, 60 meters long, 10 meters wide, and 1.3 meters deep, equipped with shading and rainproof facilities and inflatable equipment as the rest pool, and disinfect it according to conventional methods before use.

[0042] (2) Preparation of seawater for recuperation: natural seawater is extracted from the sand filter well, the specific gravity of seawater is 1.026, the specific gravity of seawater is reduced to 1.024 by adding fresh water, filtered by fine sand layer, and then filtered by pearl shell powder with a particle size of 0.15mm and a thickness of 50cm Inject into the pool prepared in step (1) with a water depth of 1.2 meters.

[0043] (3) Selection of nucleated mother oysters: Choose the nucleated mother oysters with a shell age of 18 months, a smooth shell surface, and a correct sh...

Abstract

The invention discloses a pinctada martensii pearl cultivation shellfish recuperation method, and belongs to the technical field of aquaculture. The method comprises the following steps: transferring pearl shells subjected to a nucleus implantation operation to a recuperation pool for cultivation, keeping microwave inflation, starting to feed from the third day after the operation, feeding in the morning and evening every day, feeding chrysophyceae and microcapsule feed as food for the pearl shells, and feeding vitamin D and lysine hydrochloride as nutrition additives, wherein the cultivation density of the pearl shells is 100-120 / m < 3 >, and the hanging water depth is 1.0-1.2 m; in the nucleus implanting and pearl culturing process of the pinctada martensii, seawater filtered by a fine sand layer and shell powder is used as postoperative recuperation water for nucleus implanting of the pinctada martensii, and the specific gravity of the seawater is set to be 1.020-1.025; by adopting the method for post-operation recuperation of the Pinctada martensii, the survival rate of the Pinctada martensii is high, the nucleus reserving and pearl forming rate is high, and the method is suitable for post-operation recuperation of the seawater Pinctada martensii, easy to popularize and apply in production enterprises and good in economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating and recuperating in Pinctada martensii. Background technique [0002] Pinctada fucata martensii (Dunker) is also known as Hepu pearl oyster. The sea pearls produced by Pinctada martensii in the coastal areas of the Beibu Gulf of China are called Nanzhu, and those produced in Japan are called Akoya pearls. China's current annual output of southern pearls is about 3 tons, and the price of raw pearls is about 16,000 yuan / kg. The seawater pearls produced in our country are mainly pearls from martensitic oysters, accounting for more than 95% of the seawater pearl production. [0003] In the current production of P. martensii nucleated and nucleated oysters, the nucleated oysters after surgery are basically moved to the sea area for recuperation. Affected by the uncertainty of environmental factors such as water temperature, flow rate, specific...
