Device for determining fish gender

A device for determining fish gender, comprising:

• a housing having an upper wall, a lower wall and at least one sidewall, the at least one sidewall having an opening into the housing defined therein;
• a transparent window mounted in the upper wall of the housing;
• a photodetector mounted over the transparent window;
• a light source mounted over the transparent window;
• an ELISA plate having at least one positive well for containing at least one sample known to test positive for vitellogenin, at least one negative well for containing at least one sample known to test negative for vitellogenin, and at least one test well for containing at least one sample to be tested, the ELISA plate being movable under the photodetector and through the opening defined in the at least one sidewall;
• and
• a controller in communication with the photodetector and the light source, the controller being configured for:
• determining a first color range associated with the at least one sample known to test positive for vitellogenin;
• determining a second color range associated with the at least one sample known to test positive for vitellogenin;
• determining at least one color associated with the at least one sample to be tested;
• determining if the at least one sample to be tested contains vitellogenin based on a comparison of the at least one color associated therewith against the first and second color ranges;
• and
• indicating the at least one sample to be tested belongs to a female fish when it is determined that the at least one sample to be tested contains vitellogenin, and indicating the at least one sample to be tested belongs to a male fish when it is determined that the at least one sample to be tested does not contain vitellogenin.
