Problems solved by technology

However, direct measurement of this trait in cockles requires removal of the edible part from the shell, which results in the death of the subject, after which the subject is no longer suitable for use in the breeding process for the trait

Embodiment 1

[0026] Embodiment 1, this embodiment discloses a method for measuring the breeding value of the fatness of the clam, such as Figures 1 to 3 shown, including the following steps:

[0027] Step 1, weighing the cockles: the electronic balance 1 weighs the measuring objects one by one, obtains the mass Mn of the measuring objects and records them one by one; before weighing the measuring objects, wipe their surface with absorbent paper to remove excess body surface The excess moisture on the surface can be removed by absorbent paper to ensure the accuracy of the quality measurement of the measured object;

[0028] Step 2, the balance is unleveled; first place the beaker 2 filled with water on the electronic balance 1, then the beaker 2 is immersed in the measuring container 3 which is hollowed out, and the upper end of the measuring container 3 is connected to the iron stand 5 by setting the connecting rope 4 , the measuring container 3 is suspended in the water and does not con...

Embodiment 2

[0037] Embodiment 2, the difference between this embodiment and Embodiment 1 is that in step 1, the surface of the measuring object is dried by a dryer before weighing to remove excess moisture on the body surface, and the dryer In the drying process, the drying temperature is not more than 30 degrees Celsius, and the measurement object is dried by the dryer to avoid the need for manual wiping one by one in Embodiment 1, and the accuracy of the quality measurement of the measurement object can be guaranteed, and the removal measurement can be improved. Efficiency of working with excess water on the subject's body surface.

[0038] In summary, the present invention has the following beneficial effects:

[0039] By measuring the individual density of cockles to indirectly reflect its plumpness, and converting the individual density into a breeding value, and then reflecting the traits of individual plumpness through the breeding value, it is convenient for the breeding of cockle...

Abstract

The invention discloses a method for measuring the fatness breeding value of tegillarca granosa. According to the technical scheme, the method is characterized by comprising the steps of 1, weighing tegillarca granosa; 2 carrying out a descaling operation on the balance; 3, measuring and calculating the buoyancy; 4, recording data; and 5, carrying out breeding calculation, namely, obtaining the volume Vn=V<discharge>=Fn / (rho*g) of the measured object according to the fact that the buoyancy borne by the object in water is equal to the volume of discharged water, and then performing calculationaccording to a breeding calculation formula, so that the fatness breeding value of tegillarca granosa is equal to (1.85-Mn / Vn) / 0.4*100. According to the method, the fatness of tegillarca granosa is indirectly reflected by measuring the individual density of tegillarca granosa, the individual density is converted into the breeding value, and the character of the individual fatness is reflected through the breeding value. The method has the effects that the character breeding work of tegillarca granosa is facilitated, and the fatness is reflected without causing the death of tegillarca granosa cannot in the measuring process.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for measuring the breeding value of the fatness of cockles. Background technique [0002] Mud cockles belong to the phylum Molluscs, class Bivalvia, order Dendonta, family Cockles, and the genus Cockles. Chinese traditional cultured shellfish. It is distributed all over the coast of China, and the spawning period from August to October is the peak production season. In addition, artificial breeding is carried out in Hebei, Shandong, Zhejiang, Fujian, and Guangdong, and the output is quite abundant. Clam meat is delicious and can be eaten fresh or soaked in wine, or dried. Clam meat contains a lot of protein and vitamins. The blood of cockles is bright red, and there is a golden-like color line on the edge of the meat. Mud cockles belong to the phylum Molluscs, class Bivalvia, order Dendonta, family Cockles, and the genus Cockles. Chinese traditional cultured shel...
