specific Embodiment approach 1

[0014] Specific implementation mode one: the present implementation mode provides a kind of living body continuous measurement method of cold-water fish roe or seed morphological character, specifically is finished according to the following steps:

[0015] 1. Prepare the measuring tank and inject water into the measuring tank; wherein, the bottom of the measuring tank has a ruler with a minimum scale of 1mm;

[0016] Two, fish roe or fry are transferred to the measuring tank of water injection that step 1 obtains from the culture tank;

[0017] 3. Adopt image acquisition equipment to collect image data perpendicular to the water surface in the measuring tank of step 2 to fish roe or seed in the measuring tank; wherein, the area of ​​collecting images completely covers the measuring tank area;

[0018] 4. Transfer the fish roe or seed in the measuring tank in step 3 to the culture pond;

[0019] Five, adopt computer image processing measurement software to measure the image d...

specific Embodiment approach 2

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the measuring tank in the first step is a glass tank with a top opening of 10cm×10cm×3cm and a wall width of 1mm. Others are the same as in the first embodiment.

[0025] The glass tank described in this embodiment not only ensures that it is not easy to be broken, but also ensures light transmittance.

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the height of the water in Step 1 is 3 mm to 15 mm. Others are the same as in the first or second embodiment.

[0027] The height of the water described in this embodiment is 3 mm ~ 15 mm, because the water is too shallow to cause hypoxia, and the water is too deep to affect the clarity of the photos taken. Controlling the height of the water surface can make the side of the fish species flat in the measurement tank Bottom, to reduce the error of measurement.

Abstract

The invention discloses a living body continuous measurement method of morphological traits of cold water roes or fry, relates to the field of living body continuous measurement methods of the roes or the fry and aims to overcome the defects that measurement errors are large, the roes or the fry are / is prone to deform and die, and the difficulty is high in the continuous measurement study process in terms of existing measurement methods of the roes or the fry. The method includes that (1) a measuring tank is prepared and water is filled in the measuring tank; (2) the roes or the fry are / is transferred into the measuring tank; (3) the roes or the fry are / is subjected to image acquisition; (4) the roes or the fry are / is put back; and (5) image data are subjected to analysis and measurement by software, calculation is performed by means of a scaling formula to obtain actual morphological data of the roes or the fry, and namely the living body continuous measurement of the morphological traits of the cold water roes or fry is completed. The method is suitable for the field of cold water fish breeding industries.

Description

technical field [0001] The invention relates to the field of continuous measurement methods for live fish eggs or fry. Background technique [0002] Cold-water fish has the characteristics of tender meat, rich nutrition, large edible part, no intermuscular spines, and easy processing. The most important thing is that the muscle has a high protein content and contains a large amount of unsaturated fatty acids. , People's daily living standards are constantly improving, and traditional fish species such as green carp, grass carp, silver carp, and bighead carp cannot fully meet people's consumption needs. Therefore, my country's cold-water high-quality protein fish farming industry is developing very rapidly. At present, cold-water fish has become one of the important sources of high-quality protein and nutrients in my country and even in the world. In recent years, with the national and local governments attaching great importance to the cold-water fish farming industry, the a...
