The nature of prey selection by two centrarchids (white crappie and bluegill) is presented as a model incorporating optimal foraging strategies. The visual field of the foraging fish as represented by the reactive distance is analysed in detail to estimate the number of prey encounters per search bout. The predicted reactive distances are compared with experimental data. The energetic cost associated with fish foraging behaviour is calculated based on the sequence of events that takes place for… 

Mechanisms of selectivity in a nocturnal fish: a lack of active prey choice

A low visual acuity in A. annularis, as inferred from its inability to detect small prey, together with the low abundance of large zooplankton in situ, can explain the dominance of differential encounter over active choice in this nocturnal coral-reef fish.

Patch exploitation by planktivorous fish and the concept of aggregation as an antipredation defense in zooplankton

The individual risk of a planktonic prey (Daphnia) increased rather than decreased with prey density up to 20‐30 individuals L21, suggesting that planktivorous fish (roach [Rutilus rutilus L.]) preferentially feed where prey is more abundant, and confirming that planktonics prey may use both high- and low-density antipredation refuges at densities greater than 30 and lower than 20 individuals L20, respectively.

Selectivity by planktivorous fish at different prey densities, heterogeneities, and spatial scales

The reversed slope of the selectivity-on-prey-density regression was linked to increased swimming speed at low prey density, where the fish, less constrained by the limited size of the experimental system, accelerate, possibly in an effort to compensate for low encounter rate and to more rapidly locate patches of prey.

The Influence of Structural Complexity on Fish–zooplankton Interactions: A Study Using Artificial Submerged Macrophytes

This study separated the effects of swimming speed variation and of visual impairment, both due to stems, that led to reduced prey–predator encounters and examined how the reduction of the visual field volume may be predicted using a random encounter model.

Joint evolution of predator body size and prey-size preference

The joint evolution of predator body size and prey-size preference is studied based on dynamic energy budget theory and explains various empirical observations, such as the triangular distribution of predator–prey size combinations, the island rule, and the difference in predator– prey size ratios between filter feeders and raptorial feeders.

Calculation of search volume on cruise-searching planktivorous fish in foraging model.

Results on the changes in feeding rate can be useful in determining microhabitat requirement of P parva and othercyprinids with a similar foraging behavior and the effect of zooplankton-planktivore interactions on aquatic ecosystem is discussed.

Swimming restricted foraging behavior of two zooplanktivorous fishes Pseudorasbora parva and Rasbora daniconius (Cyprinidae) in a simulated structured environment

It is found that the reductions in swimming speed with reduced average stem distance are due to the differences in fish movement per tail beat, and this was due to species-specific differences in the distance moved with one tail beat.

The effect of habitat complexity on the contribution of some littoral–benthic Cladocera to the pelagic food web

In inverse correlations between the density of Alonella and potential invertebrate predators in distinct habitats were found, suggesting that the predation pressure by planktonic invertebrates influences the demography and life-history trade-offs of juvenile Alonella individuals in the lake.

Otter diet changes in a reservoir during a severe autumn drought

Eurasian otters (Lutra lutra) are known to make extensive use of reservoirs in the Iberian Peninsula, where they forage preferentially on small-size fish (10–20 cm). We hypothesized that the usual

Stomach contents, including insects, zooplankton, crustaceans, fishes, plants and inorganic debris, showed highly generalized feeding, although insects were frequently taken, particularly during spring–summer, with chironomids being a principle dietary item.

Optimal Foraging and the Size Selection of Prey by the Bluegill Sunfish (Lepomis Macrochirus)

Evidence is presented that changes in diet maximize return with respect to time spent foraging in the bluegill sunfish, Lepomis macrochirus, that is known to select prey on the basis of size.

Foraging Efficiency and Body Size: A Study of Optimal Diet and Habitat Use by Bluegills

Habitat use of large bluegills was shown to maximize foraging return as fish switched from utilizing vegetation- living prey to utilizing open-water zooplankton as relative foraging profitabilities in the two habitats changed across the summer.

Omnivorous zooplankton and planktivorous fish

The effect of predacious zooplankton on the energy gain of planktivorous fish is estimated and the relative capture frequency of prey by fish at low plankton densities when selectivity is minimal is predicted.

Abstract Insights into the dynamics of fish growth can be gained by using foraging theory to link bioenergetics models of fish and their prey. These links are critical for modeling fish daily ration

Growth-related constraints on diet selection by sunfish

Small sunfish (<20 mm standard length [SL]) were more selective than was predicted by the apparent size model and preferentially attacked small—sized Daphnia, whereas the optimal foraging "prey" model predicted a preference for large Daphnian for all sizes of fish.

FISH SIZE, VISUAL RESOLUTION, AND

It is suggested that visual capability imposes a constraint on the ability of small bluegills to choose prey, because diet selectivity was highly significantly correlated with the fishes' visual resolution in the authors' experiments.

The nature of prey selection by planktivorous fish is presented as a model and the effects of prey distribution, encounter rate, handling time, capture success, and optimal foraging on food selection are explicit.

Flexible search tactics and efficient foraging in saltatory searching animals

A net energy gain simulation model was developed that predicts that if the greater search times observed when crappie feed on small prey are assessed when they feed on a mixed diet of small and large prey, net energy gained is less than if small prey is deleted from the diet.
