SynopsisAnimals that forage for discrete, isolated resources are often characterized as either ‘ambush’ (sit-and-wait) or ‘cruise’ (active) searchers. Juvenile white crappie, Pomoxis annularis, search for zooplankton prey using a saltatory search (SS) strategy. Unlike ambush and cruise search, SS involves scanning for prey only during the brief stationary periods that punctuate repositioning movements. If prey are not found, these fish swim a short distance, stop, and scan again. In this paper… 

Saltatory search in a lateral line predator

The dwarf scorpionfish adopted a search behaviour that is consistent with a saltatory search and efficient for lateral line predation and showed a spiralling or looping pattern over a search path exhibiting a turn bias towards either the left or right.

Optimal foraging as the criteria of prey selection by two centrarchid fishes

The energy consideration and visual system, apart from the forager's ability to capture prey, are the major determinants of prey selectivity for large-sized bluegill and white crappie still at planktivorous stages.

An examination of saltatory predation strategies employed by fish larvae foraging in a variety of different turbulent regimes

The paper demonstrates that saltatory predation is indeed a robust and optimal strategy in the sense described, provided the larva’s travel speed is not too high, and when subject to very high levels of turbulence a larva's net energy gain peaks and then falls, leading to a prediction that it would stop foraging altogether, or seek an escape from such an environment.

Foraging behaviour of Atlantic cod (Gadus morhua) larvae in relation to prey concentration

The ontogeny of foraging behaviour of Atlantic cod larvae exposed to different prey concentrations from hatching to metamorphosis is investigated to determine if their foraging behaviours are influenced by prey concentration.

Feeding ecology of early life stages of mesopelagic fishes in the equatorial and tropical Atlantic

The trophic ecology of the early ontogenetic stages of six mesopelagic fish species, which have different morphologies, vertical distributions, and taxonomic affiliations, showed positive selection for particular prey.

Visual field of cultured striped trumpeter Latris lineata (Teleostei) larvae feeding on rotifer prey

The visual field of striped trumpeter Latris lineata larvae fed rotifer prey was determined from analysis of feeding behaviour in the horizontal plane, confirming the predicted horizontal visual field, forward and laterally directed, derived from higher cone cell densities in the dorso-temporal and medial regions of the retina compared with ventral regions.

Effect of turbulence on the energetics of foraging in Atlantic cod Gadus morhua larvae

The NEG model demonstrates the need to carefully reassess the underlying assumptions of current turbulence-effects models and, therefore, the conclusions that have been based upon those models and indicates that it would be prudent to reconsider the conclusions of any previous study that was based upon over-simplified search space geometries.

Behavioural and anatomical measures of visual acuity in first-feeding Yellowtail Kingfish (Seriola lalandi) larvae

Analysis of prey search behaviour of Seriola lalandi larvae indicated that larvae employ a saltatory type search behaviour in which brief stationary periods are interspersed with repositioning movements, thereby increasing the search area of larvae.

Ontogenetic changes in behavioural and histological measures of visual acuity in three species of fish

Investigating the ontogenetic changes in visual acuity of early life history stages of alewife,Alosa pseudoharengus, yellow perch, Pererca flavescens and bloater across a range of sizes indicates that fish are anatomically more capable of seeing objects than the behavioural response suggests.

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.



A new view of the predation cycle of a planktivorous fish, white crappie (Pomoxis annularis)

Evidence is presented that white crappie (Pomoxis annularis) are neither cruise or ambush feeding strategists, and that the probabilities of detecting and pursuing a prey following a run or an attack do not differ significantly.

A Reevaluation of the Search Cycle of Planktivorous Arctic Graylings Thymallus arcticus

It is observed that the planktivorous feeding behavior of the grayling was more consistent with the strategy of saltatory search, and the relationship between the ability to locate prey and the components of search suggests that thegrayling alter the component of search.

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.

Feeding Ecology of Young White Crappie in a Kansas Reservoir

It was found that crappie between 8 and 17 cm long to be wholly pelagic, and daphnia, even when relatively sparse, made up much of the diet whereas diaptomid copepods were relatively rare.

Comparison of Searching Behavior for Zooplankton in an Obligate Planktivore, Blueback Herring (Alosa aestivalis) and a Facultative Planktivore, Bluegill (Lepomis machrochirus)

Studies of zooplankton feeding by juvenile blueback herring and juvenile bluegills indicate that they search by markedly different methods, suggesting they take the first prey item seen, rather than choosing between prey.

Behavior and survival of northern anchovy Engraulis mordax larvae

The object of this review was to provide an understanding of the behavioral factors that determine whether or not larvae of the northern anchovy, f f igrads mordax Girard, will starve. The swimming

Habitat Choice and Phenotype‐Limited Feeding Efficiency in Bluegill: Individual Differences and Trophic Polymorphism

Results indicate that behavioral and morphological variation among individuals can influence habitat-specific feeding efficiency and habitat selection, and may also have direct conse- quences for models of density- and frequency-dependent habitat selection.

Changes in Behavior With Increasing Experience With a Novel Prey in Fry of the Central American Cichlid, Cichlasoma Managuense (Teleostei: Cichlidae)

The multiple regression model revealed that, although the fish grew during the experimental period, their increased size did not contribute significantly to the increase in capture success, and the morphological variable weight was negatively correlated with capture success.

The behavioral and morphological correlates of differential capture success at first feeding of the cichlid fish Cichlasoma managuense were investigated and large behavioral variation was observed and may be the substrate for later food specialization.
