“…We focused on 3 fyke net locations (approximately between river km 71 and 75, Fig. 1) that encompassed the focus of white perch spawning activity in the Patuxent River estuary (see also Mansueti 1961Mansueti , 1964 and collected perch on 5 occasions in each of 2 consecutive years (2001: 10, 16, 24, 30 March, 5 April;2002: 13, 21, 25 March, 1, 8 April). A similar period and duration of sampling were chosen in each year to ensure that most of the spawning season was sampled.…”

“…The ecology of egg and larval stages has received intensive study (Mansueti 1964, North & Houde 2001. In the Patuxent, spawning takes place during spring in tidal fresh water via upriver migration of adults from brackish feeding areas (Mansueti 1961). Pelagic larvae metamorphose into juveniles that settle in littoral environments throughout the estuary and remain there during summer and fall.…”

“…Pelagic larvae metamorphose into juveniles that settle in littoral environments throughout the estuary and remain there during summer and fall. Eventually, juveniles move to deeper areas with the onset of winter and colder water temperatures (Mansueti 1961, Klauda et al 1988, SetzlerHamilton 1991. Though the abundance of a given year-class is believed to be established primarily during egg and larval stages, it is not clear after these stages why some juveniles remain in tidal freshwater habitats while others disperse downstream to brackish areas or what consequences this divergence might have to the population dynamics.…”

“…This species tends to overpopulate and stunt in inland waters outside of its native range (Scott and Crossman, 1973). White perch are highly fecund (Mansueti, 1961), have an ability to reproduce during their first year of life and can withstand a wide range of environmental conditions allowing quick establishment of this species in new water bodies (Ballinger and Peters, 1978;Hodkin, 2001). White perch often dominate fish communities within three years of discovery in Midwest reservoirs (Hergenrader and Bliss, 1971;Hergenrader, 1980;Jackson, 1999Jackson, , 2008Hodkin, 2001).…”

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.

ObjectiveModeling of fecundity with allometric, nutritional, and environmental covariates has increased sensitivity of reproductive metrics in many fish species. In estuaries with heavy anthropogenic influence, resident species often experience sublethal health impacts because of increased stress, which can include increases in gonadal pathology, intersex, or potential reproductive failure. This study models the fecundity of the estuarine species White Perch Morone americana in response to health parameters identified as signals of habitat stress, including gross pathology presentation, nutritional condition, and disease presence.MethodsSubpopulation fecundity in the Choptank River (Maryland) of the Chesapeake Bay was estimated using stereological fecundity sampling methods and modeled using information‐theoretic approaches of model selection. Nutritional and health parameters identified through health assessment techniques, specific somatic indices, and disease presence were selected as covariates.ResultNutrition demonstrated limited influence on model fit as compared to models with only conventional allometric variables such as weight and length. Of the health variables, gross pathology and somatic indices showed minimal influence on selection, but mycobacterial infection, a chronic condition in the Chesapeake Bay among temperate basses, showed measurable influence. Models with mycobacteriosis included were 40 times more likely the best fit when compared to models with only allometric parameters.ConclusionWhether this has a region‐wide influence on all subpopulations will require further research and sampling of the magnitude of mycobacteriosis infection.
