The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
The conjunction "consisting of …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.
The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. "optional" or "any" means that the subsequently described event or events may or may not occur, and that the description includes instances where the event occurs and instances where it does not.
Approximating language, as used herein throughout the specification and claims, is intended to modify a quantity, such that the invention is not limited to the specific quantity, but includes portions that are literally received for modification without substantial change in the basic function to which the invention is related. Accordingly, the use of "about" to modify a numerical value means that the invention is not limited to the precise value. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. In the present description and claims, range limitations may be combined and/or interchanged, including all sub-ranges contained therein if not otherwise stated.
In addition, the indefinite articles "a" and "an" preceding an element or component of the invention are not intended to limit the number requirement (i.e., the number of occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural unless the stated number clearly indicates that the singular form is intended.
The present invention is illustrated by the following specific embodiments, but is not limited to the specific examples given below.

The inventors have found in a long-term search that specific conjugated pi-bond-containing compounds and compounds containing-CH2CH2The O-group compounds are added into the inducer product together, so that the dissolving and dispersing properties of the inducing components can be obviously improved, and the product can be stored for a long time. The compound containing conjugated pi bonds simultaneously contains hydrophilic groups, metal ions and long carbon chains, wherein the long carbon chains have weak interaction with water, so that the compound is more prone to be combined with insoluble plant extracts, the hydrophilic groups are left in a water phase and are beneficial to the dispersion of the plant extracts in the water, the compound can be ionized in the water due to the existence of the metal ions, the solubility of the compound is improved, related atoms in the conjugated pi bonds are mostly in the same plane, so that the conjugated pi bonds have larger steric hindrance, and when a plurality of compounds containing conjugated pi bonds are combined with the insoluble substances, other particles around the insoluble substances are repelled under the steric hindrance effect, so that the dispersibility of the plant extracts in the water is further improved; containing-CH2CH2The O-group compounds likewise having and being insolubleThe ability of the conjugate to form stable micelles with the conjugated pi-bond-containing compound, however, the inventors found that only the-CH-containing compound having a specific saponification value2CH2The O-group-containing compound has the effect because it has an excessively large saponification value and contains-CH2CH2The hydrophilic chain in the O-group compound is short and difficult to form interpenetration with a conjugated pi bond large steric hindrance group, so that the micelle is unstable, the product is easy to delaminate, otherwise, the saponification value is too small, the hydrophilic chain is long, the steric hindrance cannot be broken through, and the product with stable performance cannot be obtained.
In some preferred embodiments, the conjugated π -bond containing compound and the-CH containing compound2CH2The weight ratio of the O-group compounds is 1: 2.5.
in some preferred embodiments, the co-solvent is selected from a mixture of one or more of ethanol, acetic acid, ethyl acetate, diethyl ether, acetone, xylene; further preferably, the cosolvent is a mixture of ethanol and acetic acid, and the weight ratio of the cosolvent to the acetic acid is 3: 1.
the inventor finds that the ethanol and the acetic acid in a specific proportion are used as cosolvents, so that the dispersibility of plant extracts can be improved, the effect of the plant extracts can be improved, and the cosolvents are non-toxic and harmless to water quality and aquatic organisms. The inventors found in a large number of practices that the weight ratio was 3: 1, the stability and the induction effect of the product can be balanced by mixing ethanol and acetic acid and adding the mixture into an inducer, so that the two effects can reach higher levels.
In a second aspect of the invention, there is provided a method for preparing an aquatic organism inducer as described above, the method being physical blending.

Evaluation of Performance
The performance test of the aquatic organism inducer obtained in the embodiment 1-12 is carried out, the test contents comprise new centrifugal stability, high-temperature stability, low-temperature stability and high-low temperature cycling stability, and the test results are shown in table 1.
1. Centrifugal stability: 10mL of the samples 1 to 12 are taken, centrifuged at 3000r/min for 10 minutes in a centrifuge, and taken out to observe whether layering occurs.
2. High-temperature stability: taking 30mL of the examples 1-12, placing the mixture in an oven at 50 +/-2 ℃, taking out the mixture after 48 hours, cooling the mixture to room temperature, and observing whether layering occurs or not.
3. Low-temperature stability: taking 30mL of the example 1-12, placing the mixture in a refrigerator at the temperature of-4 ℃, taking out the mixture after 72 hours, recovering the mixture to the room temperature, and observing whether layering occurs or not.
4. High and low temperature cycle stability: taking 30mL of the examples 1-12, putting the mixture in an oven at 50 +/-2 ℃ for 24 hours, taking out the mixture to return to room temperature, then putting the mixture in a refrigerator at-4 ℃ for 24 hours, taking out the mixture again to return to room temperature, and observing whether layering occurs or not after 5 times of circulation.
