The colors presented in ornamental fish determine their acceptability in the market, which is one of the main factors which
determine their price. Selecting the fish by only looking at them makes the result analysis based in statistics difficult. Thus, it has
become necessary to develop a method of quantification for practical use, which will apply minimal stress to the fish while being
economically feasible. The proposed method uses a technique which converts the colors of interest to numerical indexes usable in
statistical methods of higher precision. The results increase the abilities of fish nutrition researchers aiming to intensify the color
characteristics of fish through selective breeding and genetic engineering with the intent of reliably achieving the desired visual
characteristics for commercialization.
