Re: Largemouth food source?
Root Hog nailed it. Anything that is not a garter snake that eats one will have at best a horrible day, and at worst will never need another meal. A naïve bass might have a go at them, once. But no, they are not a food source. Several species of frogs and toads and their immature larvae (tadpoles) are likewise toxic.
I can speak from first hand experience that captive bass will initially take, then expel (and subsequently refuse) the tadpoles of bullfrogs, a species not noted as being toxic.
