water and remarkably inefficient at foraging along the shoreline for crustaceans or sunfish. If littoral or benthic forage organisms are found and consumed there may be only a few individuals within the striped bass school that benefit. Without schooling pelagic forage fish the health of the entire striped bass school suffers. Without question the health of the striped bass population rises and falls with the peaks and valleys in the threadfin shad population. Larval striped bass eat zooplankton. Small rotifers are often the first food consumed but after a few days nauplii copepods are targeted. As striped bass grow larger they eat a variety of invertebrates from adult copepods to cladocerans and insects. At approximately 95-100 mm striped bass convert to a fish diet, if available. Striped bass then continue to eat clupeid fish throughout their life unless forced to find alternate forage. When shad have disappeared from the pelagic zone of Lake Powell all sizes of striped bass from juveniles to adults revert to eating zooplankton. Juvenile striped bass are able to maintain body condition but adults gradually waste away without pelagic forage fish for sustenance. Feeding Behavior An abundance of larval shad in pelagic zones allow striped bass to feed leisurely as they travel in straight lines at low speeds consuming small shad at will. Limited swimming ability of larval shad make escape from striped bass difficult. Surface feeding activity occurs as 100-5000 striped bass gently roll and porpoise in unison. These "boils" only simmer as striped bass roll and slurp on top. Disturbance by boats cause striped bass schools to sound and then reappear a few hundred yards away as feeding resumes in a different direction. As shad grow in size and develop stronger swimming ability the surface action gets more intense as striped bass corral shad against the surface or trap them near shore. The tendency for 16
