Surprising Fact: Do bass eat bass?

Ambush predators

Largemouth bass have a reputation for being voracious ambush predators, striking their prey with lightning speed. However, under certain conditions, they will eat their own kind. Larger bass will prey on smaller bass during resource scarcity, and in high-density populations, some bass turn to cannibalism to gain an advantage over rivals. Cannibalism is a natural behavior in largemouth bass that plays a crucial role in ecosystem balance.

Competition makes cannibals

Largemouth bass are opportunistic feeders and will eat anything that fits in their mouths, including smaller bass. However, cannibalism is not the norm for these fish. They will usually only resort to eating their own kind if other food sources are scarce or if they are in competition for resources.

Large bass = large appetite

Interestingly, research has shown that larger bass are more likely to be cannibalistic than smaller ones. This is because larger bass require more food to sustain their energy levels and are more likely to view smaller bass as a potential food source.

Important part of the food chain

Despite their cannibalistic tendencies, largemouth bass are an important part of the food chain in their freshwater ecosystems. They help to control the populations of smaller fish and keep the ecosystem in balance.

Fun Facts

3 fun facts about cannibalistic bass:

  1. Cannibalism in largemouth bass is more common in crowded and limited food supply environments, which means that sometimes their own population density can drive them to turn to cannibalism.
  2. Researchers have found that smaller bass can recognize their own siblings and will avoid attacking them, while they will happily feast on other unrelated smaller bass.
  3. In some cases, large adult bass will eat their own young, especially if the young are born during a time of scarcity of other food sources. This behavior can help the adult bass to conserve energy and survive until food sources become more abundant again.


In conclusion, largemouth bass are indeed cannibals, but it’s not something they do all the time. They are opportunistic feeders that will eat anything that fits in their mouths, including smaller bass. Despite their cannibalistic tendencies, they are an important part of freshwater ecosystems and play a crucial role in keeping the food chain in balance.
