Colour marking of small fish with a marking stand for DermojetⓇ
We designed a marking stand for the DermojetⓇ, which substantially improves fish marking via needleless subcutaneous injection of dye. The marking stand allows to increase the nozzle-to-fish distance, adjust this position and to keep the jet injector fixed during operation as well as dye refilling....
