According to recent research, wild fish cannibalism is uncommon. Even though mosquitofish and guppies are known to be cannibalistic in captivity, it is very improbable that they would engage in cannibalism in the wild. Instead, the few instances of cannibalism in these fish are probably the result
, decided to analyze data collected over a 10-year period from nearly 12,000 fish belonging to 17 different species that were caught in the wild.
“In captivity, mosquitofish and guppies will practice cannibalism commonly enough that there are protocols in place in research labs and aquaculture to quickly separate offspring from the larger fish,” says Riesch, the corresponding author of the work. Riesch began the project while a postdoctoral researcher in Langerhans’ lab between 2010 and 2012.
Cannibalism was most frequent in populations with very high levels of competition for food; that is, populations lacking major predators where population densities of the fish surveyed were especially high. The work has implications not only for hobbyists or those trying to save and repopulate endangered species, but also for researchers who work in evolutionary biology and employ mosquitofish as an animal model.
