Foraging Strategies and Their Social Significance

In situ study on the control of toxic Microcystis blooms using phytoplanktivorous fish in the subtropical Lake Taihu of China: A large fish pen experiment

“…Compared with previous reports, however, there was a greater proportion of zooplankton in the guts of silver and bighead carp in our study: mean zooplankton contribution reached 31.5% and 64.7%, respectively. This greater proportion might be due to the abundant food resource in the water of Meiliang Bay, as predators tend to ignore less valuable food when more profitable ones are abundant (Krebs, 1979). In the present study, the components of food items of silver and bighead carp showed obvious temporal variation, and the selectivities of silver and bighead carp for phytoplankton increased after Microcystis predominated in the lake water.…”

Silver carp exhibited an enhanced ability of biomanipulation to control cyanobacteria bloom compared to bighead carp in hypereutrophic Lake Taihu mesocosms

“…For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.). Krebs (1979) figured out that fish will alternatively choose for profitable food where food resources are abundantly available. Ke et al (2009) found that both silver carp and bighead carp had a preference on grazing for zooplankton when reared at relatively low density.…”

Movement patterns of a group of free‐ranging mountain gorillas (Gorilla gorilla beringei) and their relation to food availability

“…As predicted by Krebs [1979], these animals spend more of their time in areas of the home range which are richer in food. This is shown in three significant positive relationships between measures of food quality and yearly ranging parameters (Table 10.…”
