Abstract

A breeding method of mottled clams comprises the following steps: (1) selecting parent shellfish, selecting sea shellfish with gonad plumpness of 30-40%, and after 15-30 days of intensive culture, the gonad plumpness can reach 80-90%; (2) feeding, applying inorganic fertilizer, adding fresh seawater day by day to water depth of 70-80cm, and controlling water transparency at 50-70 cm; (3) oviposition, drying parent shellfish in the shade by cold air blowing for about 10-15 hr by drying in the shade stimulation method, and naturally oviposition; (4) larva cultivation, namely selecting strong D-type larvae with a 300-mesh 400-mesh screen, and cultivating the larvae in separate pools at a cultivation density of 5-6 larvae per ml; (5) and (3) sowing, namely sowing when the parent shellfish grows to 0.8-1mm, and sowing in medium and low tide areas with the water temperature of 10-30 ℃, the salinity of 18-28%, the flow rate of 40-100 cm/s and the ebb and dew drying time of 2-3 hours, wherein the sowing density is 5-8 seeds/liter. The method adopts the sea area as parent shell and strictly controls the operation and parameters of each link in the process of breeding the hybrid clam, thereby greatly improving the yield and quality of the breeding of the hybrid clam.

Description

Method for breeding mottled clams
Technical Field
The invention relates to the technical field of aquatic product culture.
Background
The clam is one of the main marine economic shellfish in China. The combination of the four shellfish culture mediums, the sinonovacula constricta, the oyster and the blood clam is called as the traditional four cultured shellfish culture mediums in China. The little clam is widely distributed in the south and north coastal areas of China, and is characterized by fast growth, poor mobility, strong adaptability, short production period, simple and convenient culture method, less investment, great income and the like, thus being a beach culture shellfish with great development prospect. Meanwhile, the method can also be used for polyculture and alternate culture of the prawns by using the shrimp pond facilities, and is also a good culture mode.
The popularization of the variegated clam seedling production technology, the radiation of the production place and the seedling price trend of most farmers show great attention, and how to optimize the variegated clam seedling raising method to improve the quality and the yield of the variegated clams is a hotspot of research of people.
Disclosure of Invention
The invention provides a breeding method of mottled clams, aiming at improving the quality and yield of mottled clams.
The technical scheme adopted by the invention for realizing the purpose is as follows: a breeding method of mottled clams comprises the following steps:
(1) selecting parent shellfish, selecting sea shellfish with gonad plumpness of 30-40%, and after 15-30 days of intensive culture, the gonad plumpness can reach 80-90%;
(2) feeding, applying inorganic fertilizer, adding fresh seawater day by day to water depth of 70-80cm, and controlling water transparency at 50-70 cm;
(3) oviposition, drying parent shellfish in the shade by cold air blowing for about 10-15 hr by drying in the shade stimulation method, and naturally oviposition;
(4) larva cultivation, namely selecting strong D-type larvae with a 300-mesh 400-mesh screen, and cultivating the larvae in separate pools at a cultivation density of 5-6 larvae per ml; feeding golden algae and Chaetoceros for 2-4 times per day, with 2-4 ten thousand cells/ml;
(5) and (3) sowing, namely sowing when the parent shellfish grows to 0.8-1mm, and sowing in medium and low tide areas with the water temperature of 10-30 ℃, the salinity of 18-28%, the flow rate of 40-100 cm/s and the ebb and dew drying time of 2-3 hours, wherein the sowing density is 5-8 seeds/liter.
And (3) soaking the collected parent scallops in 20mg/L potassium permanganate for 10min, washing, spreading on a net rack, drying in the shade, putting the parent scallops into a spawning basket, hanging the parent scallops in a spawning pond to spawn, and hatching in a fertilized egg primary pond at a hatching density of 10-20/ml.
The method for raising seedlings of mottled clams adopts the sea area as parent clams, and strictly controls the operation and parameters of each link in the process of raising seedlings, thereby greatly improving the yield and quality of the mottled clam seedlings.
Detailed Description
The invention relates to a breeding method of mottled clams, which comprises the following steps:
(1) selecting parent shellfish, selecting sea shellfish with gonad plumpness of 30-40%, and after 20 days of intensive culture, the gonad plumpness can reach 80-90%;
(2) feeding, applying inorganic fertilizer, adding fresh seawater day by day to water depth of 80cm, and controlling water transparency at 50 cm;
(3) oviposition, drying parent shellfish in the shade by adopting a shade drying stimulation method, adding cold air to blow for about 10 hours, naturally oviposition, soaking the collected parent shellfish in 20mg/L potassium permanganate for 10min, washing, spreading on a net rack, drying in the shade, filling the parent shellfish into a oviposition basket, hanging in a oviposition pool to oviposition, hatching in a fertilized egg primary pool, and hatching at the density of 10-20 eggs/ml;
(4) breeding larvae, namely selecting strong D-type larvae with a 300-mesh screen and breeding in separate ponds, wherein the breeding density is 5-6 larvae per ml; feeding golden algae and Chaetoceros for 3 times a day, wherein the feeding amount is 3 ten thousand cells/ml;
(5) and (3) sowing the seedlings when the parent shellfish grows to 1mm, and sowing the seedlings in medium and low tide regions with the water temperature of 20 ℃, the salinity of 25 percent, the flow rate of 60 cm/s and the ebb and dew drying time of about 2-3 hours, wherein the sowing density is 5-8 seeds/liter.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
