Problems solved by technology

[0004] The markers selected in the traditional marker release experiment are easier to track and observe, and their density is lower than that of water, and they float on the water surface, such as large fungus, coriander, pepper seeds, etc., which are quite different from the actual fish egg density and shape. , the experimental results are open to question

preparation example Construction

[0021] The embodiment of the present application provides a method for preparing a fish egg model. The method includes:

[0022] Polysaccharide S-60, (C 12 h 18 o 9 ) n and (C 6 h 7 o 6 Na) n The aqueous solution is heated to 95-100°C, and poured into a mold to cool to form a fish egg model;

[0023] The mass fraction of the aqueous solution is 2.4~2.6%; polysaccharide S-60, (C 12 h 18 o 9 ) n and (C 6 h 7 o 6 Na) n The mass ratio is 3.5~4.6:3.5~4.6:1.0~2.5.

[0024] The mass fraction of the aqueous solution is 2.4-2.6%, polysaccharide S-60, (C 12 h 18 o 9 ) n and (C 6 h 7 o 6 Na) n The mass ratio is 3.5~4.6:3.5~4.6:1.0~2.5. The density of the solution mixed with the input mass and water is close to the egg density of the target fish, and can be close to the physical characteristics of real fish eggs, thus greatly improving the convenience and accuracy of the experiment when studying the movement of fish eggs in rivers. Polysaccharide S-60, (C 12 h ...

Embodiment 1

[0080] Present embodiment provides a kind of fish roe model, makes like this:

[0081] Select two 250ml beakers to measure 100ml of purified water respectively. Take a beaker and add the polysaccharide S-60 powder weighed on the electronic balance and (C 12 h 18 o 9 ) n Powder blend powder (polysaccharide S-60 powder 2.308g, (C 12 h 18 o 9 ) n powder 2.308g), and stir until completely dissolved with a magnetic stirrer, forming a transparent solution for use; get another beaker and pour it into (C 6 h 7 o 6 Na) n 0.512g of powder, and stirred with a magnetic stirrer until completely dissolved to form a solution for use.

[0082] The solutions in the two 250ml beakers were mixed to form a 200ml blended solution.

[0083] Choose the water bath heating method to heat the blended solution. Set the water bath to a stable temperature of 97°C. After the water bath reaches the set temperature, place the beaker with the solution in the pot for heating, and measure the temper...

Abstract

The application relates to the field of research on the movement of fish eggs in the wild, and in particular to a preparation method and application of a physical model of fish eggs. The method comprises mixing polysaccharides S-60, (C 12 H 18 O 9 ) n and (C 6 H 7 O 6 Na) n The mixed aqueous solution is heated to 95-100 ℃, and then poured into the mold and cooled to make a fish egg model. The three materials selected are non-toxic and harmless, and can be degraded. The input in the field river experiment will not affect the ecological environment at all. In the present application, the above two substances are blended in a certain proportion to enhance the gel strength and at the same time have better properties similar to fish eggs. join (C 6 H 7 O 6 Na) n It can not only improve the water solubility of the model so that it can be decomposed in a reasonable time to avoid being eaten by wild fish, but also improve the physical strength of the model to make it more reliable and stable to withstand the scouring of water. This fish egg model controls the density, durability and tensile strength of the model by selecting the amount of addition and the heating method.

Description

technical field [0001] The present application relates to the field of research on fish egg movement in the field, and in particular, relates to a fish egg model and its preparation method and application. Background technique [0002] In recent years, more and more attention has been paid to the movement of fish eggs in rivers and their transport and distribution in river ecosystems. On the one hand, the response of fish eggs to hydrological processes with the flow has important biological significance, which is related to the successful hatching of fish eggs and the On the other hand, the migration rules of fish eggs and their dispersal characteristics in rivers are also important topics in the research and protection of early fish resources. In order to better test, evaluate and optimize the improvement effects of some ecological compensation measures, there is an urgent need for research on the drifting rules of fish eggs, the location of spawning grounds, and the estima...
