The fishing industry is the commercial activity of fishing and producing fish and other seafood products for human consumption or as input factors in other industrial processes. According to Food and Agriculture Organization (FAO) statistics the total fish production in the world in 2001 was 130 million tonnes. In addition to the commercial catches, 37.9 million tonnes were produced in aquaculture plants.
Modifying fish to make them more attractive as pets is an increasingly divisive issue. Historically, artificially dyeing fish was fairly common, with glassfish for example being injected with fluorescent dyes.
