“…Our results in this study indicated that dense vegetation could reduce feeding efficiency and growth of small fishes, which might determine small fish production and quality of small fishes as prey organisms of piscivorous fish. Meanwhile, other studies have demonstrated that high vegetation abundance could result in poor growth of piscivorous fishes (Colle & Shireman 1980, Miranda & Pugh 1997. For management of piscivorous fishes in Yangtze lakes, it is essential to manage the level of vegetation abundance to maintain high abundance and production of small fishes and the proper exploitation rate of piscivorous fishes on small fishes.…”

SynopsisSmall fish abundance is usually high in heavily vegetated habitats in Yangtze lakes, China. Visual and swimming barriers created by dense macrophytes beds could reduce feeding efficiency and growth of small fishes. We tested the hypothesis that small fishes in habitats with dense macrophytes would show decreased feeding efficiency and reduced growth rates by comparing feeding efficiency (measured as the relative weight of fore-gut contents), total length, and condition factor of four small young-of-the-year fishes collected in the near-shore (heavily vegetated) and central (less vegetated) areas of Liangzi Lake. Feeding efficiency, total length, or condition factor were each significantly reduced in the near-shore area compared with the central area for Ctenogobius giurinus, Pseudorasbora parva and Carassius auratus auratus. This supports our hypothesis that vegetation abundance may mediate feeding efficiency and growth of small fishes. Although Hypseleotris swinhonis did not show significant decreases in feeding efficiency or growth in the near-shore area, there was not any reversed tendency, i.e. increased feeding rate or growth in the near-shore area compared to the central area.

“…Maintenance of macrophyte cover is essential for high diversity and abundance of small fishes, and hence fishery yield of piscivorous fishes. On the other hand, it is also essential to regulate the level of macrophyte abundance, as other studies indicated that dense vegetation could result in low feeding efficiency and poor growth of both small fishes and piscivorous fishes (Colle and Shireman 1980;Miranda and Pugh 1997;Xie et al 2005). Further studies are needed in future to investigate the effects of macrophyte cover on predatorprey interactions of fish, and to assess ecosystem consequences of the stocking of piscivorous fishes into the Yangtze lakes.…”

-This study describes the current status of the small fish community in Niushan Lake in China, and examines the spatial and seasonal variations of the community in relation to key environmental factors. Based on macrophyte cover conditions, the lake was divided into three major habitat types: (1) Potamogeton maackianus habitat, (2) Potamogeton maackianus and Myriophyllum spicatum habitat, and (3) uncovered or less-covered habitat. Fish were sampled quantitatively in the three habitat types by block nets seasonally from September 2002 to August 2003. A total of 10 469 individuals from 27 fish species were caught, among which 20 species were considered as small fishes. Rhodeus ocellatus, Paracheilognathus imberbis, Pseudorasbora parva, Micropercops swinhonis and Cultrichthys erythropterus were recognized as dominant small fishes according to their abundance and occurrence. It was noted that (1) small fishes predominated the total number of fish species in the lake, which reflected to some degree the size diminution phenomenon of fish resources; (2) many small fishes had plant detritus as their food item, which was consistent with the abundance of macrophyte detritus in the lake and implied the importance of detritus in supporting small fish secondary production. Canonical correspondence analysis suggested that the spatial distributions of most small fishes were associated with complex macrophyte cover conditions. Macrophyte biomass was positively correlated with species richness, diversity index and the catch per unit of effort (CPUE) of the fish community. Water depth had no significant effects on species diversity and distribution of the small fishes. Correspondence analysis revealed a higher occurrence of the small fishes and higher abundance of individuals in summer and autumn. Seasonal length-frequency distributions of several species indicated that more larval and juvenile individuals appeared in spring and summer. This study provides some baseline information which will be essential to long-term monitoring of small fish communities in the Yangtze lakes.Key words: Small fishes / Freshwater community structure / Habitat utilization / Multivariate statistics / Lake fishery management / Yangtze lakes Résumé -Structure de la communauté des poissons de petites tailles du lac Niushan connecté au fleuve Yangtze (Chine).

Les échantillonnages des poissons des trois types habitats ont été effectués à différentes saisons, de septembre 2002 à août 2003.

“…Many laboratory studies on the effect of density of plants or other cover on predator-prey interactions have concentrated on changes in foraging success (Glass 1971, Mauck & Coble 1971, Minello & Zimmerman 1983, Saiki & Tash 1979, Savino & Stein 1982, Tomcko et al 1984, Schramm & Zale 1985. In the field, investigators have measured changes in growth rates or condition of predators (Crowder & Cooper 1979, Colle & Shireman 1980 or changes in prey densities (Saiki & Tash 1979, Gilinski 1984 with changes in plant density or abundance. No study, however, has dealt with changes in the behavior of foragers and prey offered a choice of habitat.…”

Behavior of fish predators and their prey: habitat choice between open water and dense vegetation

1989

SynopsisBehavior of largemouth bass, Micropterus salmoides, and northern pike, Esox lucius, foraging on fathead minnows, Pimephales promelas, or bluegills, Lepomis macrochirus, was quantified in pools with 50% cover (half the pool had artificial stems at a density of 1000 stems n -2 ). Both predators spent most of their time in the vegetation. Largemouth bass searched for bluegills and ambushed minnows, whereas the relatively immobile northern pike ambushed all prey. Minnows were closer to predators and were captured more frequently than bluegills. Even when minnows dispersed, they moved continually and eventually wandered within striking distance of a predator. Bluegills dispersed in the cover with predators. Bass captured the few bluegills that strayed into the open and pike captured those that approached too closely in the cover. The ability of predators to capture prey while residing in habitats containing patches of dense cover may explain their residence in areas often considered to be poor ones for foraging.
