DYEING AGENT FOR FISHING TOOL AND METHOD FOR GENERATING THE DYEING AGENT

PROBLEM TO BE SOLVED: To solve the following problems in marine culture: use of a fish farming net dyed with a conventional dyeing agent containing an organotin is effective for preventing sea algae or barnacles from sticking to the net, but has the disadvantage that the organotin is gradually dissolved and dispersed in a culturing sea and is liable to generate a toxic contamination of sea water; and only use of a nitrogen- or copper-containing dye base without the organotin is difficult or insufficient to prevent the sticking of sea algae or barnacles. SOLUTION: As a dyeing agent for fishing tools is provided a charcoal-based dyeing agent obtained by mixing a charcoal fine particle in a dye base comprising a nitrogen- or copper-containing synthetic resin solvent. The method for generating the dyeing agent involves mixing a charcoal fine particle having acetic acid added in the synthetic resin solvent, and stirring the mixture using a disperser.
