Problems solved by technology

Both of the above two methods obtain the volume or mass of the complete shellfish or shell indirectly, rather than directly measuring the shell cavity, and require multiple measurements and conversion calculations, which increases the measurement error
In addition, these two methods are not suitable for shellfish such as scallops whose shells are not tightly closed

Embodiment 1

[0035] (1) Prepare a 100ml measuring cylinder, distilled water, and 5 oysters to be tested (the average shell height, shell length, shell width, and wet weight are: 83.85±16.01mm, 48.36±7.86mm, 30.49±4.80mm, 57.08±21.67 g), fire retardant mud 2kg.

[0036] (2) Fill fire retardant mud into the oyster shell cavity where the soft body is removed. The amount of fire retardant mud slightly exceeds the volume of the shell cavity. After filling, close the left and right shells and squeeze hard to remove the fire retardant outside the extruded shell. mud.

[0037] (3) Take out the fire retardant putty in the shell cavity in step (2), the shape of the fire retardant putty is the shape of the shell cavity, and measure its height, length and width.

[0038] (4) Fill a certain amount of distilled water into a 100ml measuring cylinder, and record the volume V1;

[0039] (5) Knead the fire-retardant mud in the shell cavity of step (3) into a strip shape, and place it in the measuring cyli...

Embodiment 2

[0045] (1) Prepare a 100ml measuring cylinder, distilled water, and 5 oysters to be tested (average shell height, shell length, shell width, and wet weight are: 82.24±21.18mm, 52.18±25.67mm, 26.26±6.32mm, 50.50±18.91 g).

[0046](2) Put an appropriate amount of distilled water in a square tank of 40cm×20cm×10cm, submerge the oyster that has taken out the soft body into the distilled water, fill the inner cavity of the oyster with the finishing water, and tie the two shells with rubber bands to make the two shells completely closed state. Place the square tank in a -20°C refrigerator until the distilled water is completely solidified.

[0047] (3) Take out the ice around the oysters in the square tank in step (2), and take out the oysters one by one. Take out the ice in the shell cavity, the shape of the ice is the shape of the shell cavity, and quickly measure its height, length, and width.

[0048] (4) Place the ice in the shell cavity measured in step (3) in a 100ml measu...

Abstract

The invention relates to the field of aquatic biology, in particular to a method for accurately obtaining the shape of a bivalve shell cavity and measuring its volume. Filling the shell cavity of the bivalve mollusc to be treated with material, so that the filler fills and shapes the entire cavity; after compaction, the cavity filling material is taken out to obtain the complete shell cavity shape of the bivalve mollusk. The application of the method to obtain the morphology of the shellfish shell cavity in determining the volume of the shell cavity. The method can accurately obtain the shell cavity volume of the measured shellfish, and the method has universal applicability to bivalve shellfish, not only applicable to shellfish with regular shell shapes such as clams, but also to shellfish with irregular shell shapes such as oysters, and scallops, etc. The same applies to shellfish whose shell cavity cannot be completely closed.

Description

technical field [0001] The invention relates to the field of aquatic biology, in particular to a method for accurately obtaining the shape of a bivalve shell cavity and measuring its volume. Background technique [0002] The soft body of the edible part of the bivalve mollusk is wrapped by its shell, and the shell is closed to form a shell cavity. The shape and volume of the shell cavity directly determine the size of the soft body. The round shell cavity and large volume are more valuable for breeding. However, some bivalve molluscs have thick shells and strong plasticity, and the shell shape cannot fully reflect the properties of the shell cavity and soft parts. With the development of bioinformation technology, high-tech such as big data has been rapidly applied in breeding research, and 3D modeling and visualization targeting traits can achieve high-throughput acquisition, comparison, and screening of traits. Rapid advances in technologies such as genome-wide selective ...
