Predators And The Distribution And Abundance Of Blennies On Offshore Petroleum Platforms, Tommy J. Rauch
Predators And The Distribution And Abundance Of Blennies On Offshore Petroleum Platforms, Tommy J. Rauch
Gulf and Caribbean Research
Predation may be important in structuring fish assemblages but studies of the intensity of predation on marine fish assemblages are uncommon. Predator avoidance behavior was used to identify the predators of an assemblage of blennies found on offshore petroleum platforms in the northern Gulf of Mexico. The distribution of predators was then compared with the distribution of 3 species of blennies to see if predation intensity was related to the vertical zonation of blennies. Predator approaches and blenniid activity were compared in low and high surface current events. Results did not support a hypothesis of predation controlling the distribution and …
