As a breeder of stripped murrel (Channa striata), I've been facing challenges in accurately distinguishing between male and female fish through external examination alone. I've come across the potential application of ultrasound technology for this purpose. Could you please provide further details on whether your ultrasound equipment can effectively identify the sex of Channa striata? Additionally, I would appreciate information about the pricing of the ultrasound device and any guidance on its usage, including setup and effective techniques for fish examination. This will help me decide on how to integrate this technology into my breeding practices. Thank you!
