“…When predators are not gape-limited, the next logical physical limitation on food consumption is how much the stomach can hold (i.e., stomach volume or capacity) (Truemper and Lauer 2005). Stomach capacity and size of prey relative to predator should provide important insight into ecological roles of fish.…”

We investigated the relationship between stomach capacity and total body length in bluegill (Lepomis macrochirus), spotted bass (Micropterus punctulatus), white crappie (Pornoxis annularis), black crappie (Pornoxis nigrornaculatus), channel catfish (Ictalurus punctatus), and white bass (Morone chrysops). The rate of change in stomach capacity for a given change in fish length was greatest for spotted bass and channel catfish, which may indicate greater ontogenetic shifts in feeding strategies. Fish with larger stomach capacities should have more plastic diets because they are capable of consuming a wider range of prey sizes, particularly when they already have prey present in their stomach, compared to fish with smaller stomach capacities and similar feeding strategies.

“…Size-dependent growth occurred in both bluegill and yellow perch populations, with larger individuals experiencing a greater increase in length than smaller conspecifics. This growth differential may be related to intraspecific competition or gape limitation, where larger conspecifics outcompete or consume larger prey than do smaller counterparts [61][62][63] during winter when resources are limiting.…”

Substantial mortality can occur in age-0 fish populations during their first year of life, especially in winter; this can potentially influence overall recruitment into the adult population. As such, we compared relative abundances between fall and spring catches of sympatric juvenile bluegill Lepomis macrochirus Rafinesque and yellow perch Perca flavescens (Mitchill) to evaluate the magnitude of overwinter mortality across locations (five lakes for two years) and through time (one lake for six years). In addition, we compared both quantile-quantile and increment plots, based on length-frequency histograms from fall-and spring-caught cohorts from 2004 to 2010, to determine if mortality was sizeselective while accounting for over winter growth. Bluegill relative abundances (as indexed by catch-per-unit-effort) significantly decreased from fall to spring, although size-selective mortality was not detected in 10 instances. Yellow perch relative abundances were similar from fall to spring in five Nebraska Sandhill lakes; however, size-selective mortality was detected, with size-selective over winter mortality of smaller individuals occurring in one of eight instances, whereas greater mortality in larger individuals occurred in two instances. Positive growth occurred in both species but was variable among lakes and appeared to be system-specific. In Nebraska Sandhill lakes, over winter mortality likely differs between these two species in its severity, size-selective effect, and scale (i.e., lake-specific vs. large-scale processes), and is likely influenced by combinations of these (and potentially other) factors.

“…Gape limitation likely affected consumption rate on white perch more in Pawnee Lake than in Branched Oak Lake because predators were smaller (Gosch et al, 2010) and white perch were larger in Pawnee Lake (Chizinski et al, 2010). When predators are not gape-limited, stomach capacity (i.e., how much the stomach can hold) could be another physical limitation on consumption (Truemper and Lauer, 2005;Gosch et al, 2009). Other factors such as growth rate of predators and prey, predator hunting mode, prey avoidance behavior, and habitat overlap between predators and prey could also influence consumption rate.…”

Key-words:biological control, predation, consumption rate, white perch, Morone americana Control of undesirable fishes is important in aquatic systems, and using predation as a tool for biological control is an attractive option to fishery biologists. However, determining the appropriate predators for biological control is critical for success. The objective of this study was to evaluate the utility of consumption rate as an index to determine the most effective predators for biological control of an invasive fish. Consumption rate values were calculated for nine potential predators that prey on white perch Morone americana in Branched Oak and Pawnee reservoirs, Nebraska. The consumption rate index provided a unique and insightful means of determining the potential effectiveness of each predator species in controlling white perch. Cumulative frequency distributions facilitated interpretation by providing a graphical presentation of consumption rates by all individuals within each predator species. Largemouth bass Micropterus salmoides, walleye Sander vitreus and sauger S. canadensis were the most efficient white perch predators in both reservoirs; however, previous attempts to increase biomass of these predators have failed suggesting that successful biological control is unlikely using existing predator species in these Nebraska reservoirs.
