Both fish communities were simple but quite different--Marsh Lake contained no top-level piscivores while Pelican Lake did.
Although direct predation on Weakfish by the 4 piscivores investigated was high at different times during our study, large numbers of Weakfish were also collected in our surveys, indicating high availability of this prey type.
Although benthic foragers (such as Summer Flounder) are generally more light sensitive than are other estuarine pelagic piscivores (Horodysky et al.

A new threat that has emerged since wild bonytails have declined is proliferation of many large-bodied and small-bodied piscivores (Mueller, 2005; Bestgen et al.
Other small-bodied fishes, such as red shiner Cyprinella lutrensis that are not considered traditional piscivores, also have been implicated in decline of native fishes in the Colorado River Basin (Ruppert et al.
We speculate that the reduction in abundance of the four most dominant day taxa is due to fish seeking refuge around medium- to larger-size structures because of the potential presence of large piscivores (Wilkins, 1986; Adams, 1987), rather than to schooling in the water column.
These scoring thresholds roughly categorize piscivores to higher trophic levels, omnivores to intermediate trophic levels, and planktivores to lower trophic levels (Pauly et al.
Today, this non-native predator occupies a dominant position in the guild of large piscivores on many reefs in the MHI (see Results section).
retain their marine isotope signal after spending part of the spring spawning in freshwater, and that some freshwater piscivores are [sup.
Theoretically, these large piscivores are capable of structuring prey fish populations through predation and prey selection (Bax, 1998; Harvey et al.
