In their article "Genetic Monogamy of the Channel Catfish, Ictalurus Punctatus, a Species with Uniparental Nest Guarding", Audrey Tatarenkov, Felipe Barreto, Dana L. Winkelman, and John C. Avise research the parental systems regarding the care of catfish eggs after they are laid, by keeping tabs on several nests and their resident catfish. After identifying the kind of "families" the catfish construct, they had catfish noodlers take out the main protectors (since only one male catfish stayed at each nest most of the time) so they could count the amount of eggs in each mass and then examine the catfish that were in charge of guarding it. They write in order to disclose a new theory that there is actually lifelong monogomy among catfish, and that they form families that are not so different from human families, having several generations located in any given nest. Their intended audience are biology researches specifically interested in the species of catfish located in water channels in the southern United States.
