AI Technical Summary
Existing fish parasite collection devices lack a dedicated gill-opening mechanism, resulting in the gill filaments being tightly adhered during collection. This makes it difficult for the brush to fully contact the parasitic area and can easily damage the gill filaments, affecting the integrity of the sample.
A collection device incorporating a gill-opening component was designed. The gills are opened by a collar and a support plate structure, and combined with a scraper and piston design, the device achieves efficient collection and sealed storage of parasites.
This method achieves stable opening of the fish gills, ensuring the integrity and safety of parasite samples, reducing equipment costs, and improving collection efficiency.
