Food composition of Abramis brama was studied in the shallow, meso-eutrophic Hamry reservoir (Czech Republic). Fish were sampled during the daytime in the pre-spawning period (April), the post-spawning (June), summer (July) and autumn (October) in 2011. The bream sampled comprised two main size groups: small (124-186 mm) and large (210-315 mm) standard length. Twenty specimens of each size group (except April - 40 large fish) were taken for analysis on each sampling occasion. Food composition was evaluated using gravimetric methods. Over the whole season, detritus and aquatic vegetation were the dominant dietary items taken. During summer, the diet of large bream comprised mainly aquatic vegetation. Benthic macroinvertebrates and zooplankton formed a minor part of bream diet over the whole season. Specific food habits of bream could be explained by specific conditions within the reservoir and available food resources.

Commercial fish landing at Abu Qir and Alanfoushy markets was the source of Siganus rivulatus and Siganus luridus sampled for food and feeding habits analysis. Food indices and food content were studies in stomach analyses of 1485 fishes

The availability of multiple sources of food and drink has a profound influence on choice behavior in rodents. It is not known how other taxa might respond to the same kind of variation in availability. We tested European starlings (Sturnus vulgaris) with various combinations of unadulterated and repellent-treated (0.025% citronellyl acetate) resources. In Experiment 1, birds drank more plain than repellent-treated water than when given (a) 2 bottles of plain water and 2 of repellent-water, or (b) 3 bottles of plain water and 1 of repellent-water. However, they drank more repellent than water when given 3 bottles of repellent-water and 1 of plain water. Thus, the aversion to the repellent became indifference when repellent-water was abundant. In Experiment 2, birds ate more untreated than treated food when given (a) 1 cup of untreated food and 1 cup of treated food or (b) 2 cups of untreated food and 1 of treated food. They ate equal amounts of untreated and treated food when given 1 cup of untreated food and 2 cups of treated food. These results demonstrate the effect of relative availability on choice, and imply that availability should be considered when using repellents.

The food remains of Neomys fodiens (particularly trichopteran larvae, Gastropoda and Amphibia) found on the banks of ponds and small creeks in Lower Austria are described. Characteristic bite marks, the manner of opening the cases and shells, as well as data on feeding patterns are presented. Food caches mainly consisted of caddis fly larvae and snails, but also contained non-palatable items which shrews apparently had confused with real prey and retrieved. The composition of the caches varied seasonally, showing a marked mid-summer decline and a shift in the proportion of Trichoptera and Mollusca in late summer and autumn. Shrews employed particular methods when breaking snail shells and opening caddis fly cases, and in the consumption of vertebrate carcasses.
