Embodiment 1

[0008] In an empty pool with a depth of 1 m, put 8 cm deep sea water, and then put 300 mesh zeolite powder at a dosage of 1.5 kg / m 2 , stir evenly, when the zeolite powder settles, release the upper layer of clear water, then put it into 30cm deep sea water, stir evenly, after the zeolite powder settles, release the upper layer of clear water, and finally put it into a pool full of sea water, after the zeolite powder settles, according to the amount per milliliter of sea water Put in 2 clam larvae to attach to live.

Embodiment 2

[0010] In an empty pool with a depth of 1.7m, put 15cm deep seawater, and then put 300 mesh zeolite powder at a dosage of 1.8kg / m 2 , stir evenly, when the zeolite powder settles, release the upper layer of clear water, then put it into 35cm deep sea water, stir evenly, after the zeolite powder settles, release the upper layer of clear water, and finally put it into a pool full of sea water, after the zeolite powder settles, according to the amount per milliliter of sea water Put in 2 clam larvae to attach to live.

Embodiment 3

[0012] In an empty pool with a depth of 1.3m, put 10cm deep seawater, and then put 300 mesh zeolite powder at a dosage of 2kg / m 2 , stir evenly, when the zeolite powder settles, release the upper layer of clear water, then put it into 32cm deep sea water, stir evenly, after the zeolite powder settles, release the upper layer of clear water, and finally put it into the full pool of sea water, after the zeolite powder settles, according to the amount per milliliter of sea water Put in 2 clam larvae to attach to live.

Abstract

The invention relates to a method for using 300-mu zeolite powder as a Scapharca subcrenata and juvenile mollusk attachment base. The method comprises the following steps of: putting 8-15 cm of seawater in an empty tank with the depth of 1-1.7 m, putting 1.5-2 kg / m2 of the 300-mu zeolite powder, uniformly stirring, and discharging upper water after the zeolite powder precipitates; then, putting 30-35 cm of seawater, uniformly stirring and discharging upper water again after the zeolite powder precipitates; and finally, putting seawater till the tank is full, and putting Scapharca subcrenata larva to be attached after the zeolite powder precipitates. According to the method disclosed by the invention, the problems of being fussy in treatment process, high in cost, inconvenient for screening, non-strict for sterilization and resulted in diseases in the current Scapharca subcrenata and juvenile mollusk attachment base can be solved; the Scapharca subcrenata and juvenile mollusk attachment survival rate is increased; the attachment survival rate can be increased to 28-35%; the growth speed is increased; furthermore, the treatment method is simple; without sterilization, the attachmentbase can be prevented from bringing about harmful organisms; furthermore, the method has the functions of purifying water quality, adsorbing ammonia, nitrogen and bacteria and the like; and the effect is obvious.

Description

technical field [0001] The invention relates to a method for using 300-mesh zeolite powder as an attachment base for clam spat. Background technique [0002] Cockle larvae float in seawater, and when the shell length is 220 μm, "eye spots" appear, and they are about to enter metamorphosis life. At present, polyethylene mesh or fine soil are mostly used as attachment bases for cockle seedling spat. Polyethylene mesh has the problems of cumbersome processing procedures and high cost; fine soil is inconvenient to screen and not strictly disinfected, and it will also bring in diseases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method of using 300-mesh zeolite powder as the attachment base of clam spat. The method has low cost, simple treatment method, and can prevent the attachment base from carrying harmful organisms without disinfection. [0004] Technical solution of the present invention is: [000...
