Effect of regurgitation on stomach content data of marine fishes

  • Ray E. Bowman
Article

Synopsis

Observations on trawl caught fishes from two bottom depth ranges in Southern New England shelf waters provide evidence that some species regurgitate at different rates when sampled at various depths and further, that fish which regurgitate can't always be detected by external or internal examination. Generally, gadoid fishes are much more prone to regurgitate than flatfish. The consequence of unrecognized regurgitation is discussed in relation to consumption estimates derived by traditional methods.
