Population biology of bay anchovy Anchoa mitchitli in the mid Chesapeake Bay

Distribution and transport of bay anchovy (Anchoa mitchilli) eggs and larvae in Chesapeake Bay

Mechanisms and processes that influence small-scale depth distribution and dispersal of bay anchovy (Anchoa mitchilli) early-life stages are linked to physical and biological conditions and to larval developmental stage. A combination of fixed-station sampling, an axial abundance survey, and environmental monitoring data was used to determine how wind, currents, time of day, physics, developmen...

Spatial and Temporal Patterns in Recruitment Process SCALE AND PATTERN IN RECRUITMENT PROCESSES OF BAY ANCHOVY IN CHESAPEAKE BAY

Recruitment of bay anchovy (Anchoa mitchilli) varies annually in Chesapeake Bay, and levels and patterns are related to variability in hydrological conditions and the spatial distribution of spawning stock biomass. Midwater-trawl surveys, conducted three times annually from 1995-1999, over the entire 320-km length of the Bay, provided information on annual and regional patterns of recruitment, ...

Explaining advection: do larval bay anchovy (Anchoa mitchilli) show selective tidal-stream transport?

Bay anchovy (Anchoa mitchilli) have been reported in several systems to display net up-estuary larval movements, against the mean flow. However, the means by which such transport occurs is poorly understood. We address how estuarine circulation and larval behaviors serve to transport larvae of the bay anchovy. In two successive summer seasons, we conducted multiple near-synoptic samples of larv...

Interactive Chesapeake Bay Simulation

Scientists use sophisticated numerical models to study ocean circulation and other physical systems, but the complex nature of such simulation software generally make them inaccessible to non-expert users. In principle, however, numerical models represent an ideal teaching tool, allowing users to model the response of a complex system to changing conditions. We have designed an interactive simu...
