Salex,

Don't count out crayfish just yet. Notice their energy density. In that NP study the lake that recorded the most growth contained carp and crayfish as the primary sources of prey for NP. The NP growth in that lake blew away the other lakes which recorded growth right along the path that was then thought to be the maximum possible. So carp and crays pushed the envelope that redefined what the maximum path could be and what high energy prey can do. NP have exceptionally low energy density themselves and are consequently more sensitive to variation of prey energy density than predators of higher energy density.

You may be interested in reading th...ve energy density of prey was discussed.
