ChesMMAP Trawl Survey

Over time, any number of uses can and will be made of our data.  Though the survey is designed to support multispecies and ecosystem modeling many other traditional and non-traditional analyses are planned.

Several of the early analyses we have performed are available here...

• Number of fish caught, number measured only, and number 'worked up' (length-weight-sex-age-diet) by cruise.  click here
• Species distribution comparison maps for 2002 (Note: The "N=" numbers presented on these figures should NOT be taken as absolute population estimates.  The do represent a 'minimum trawlable number' uncorrected for gear efficiency and gear selectivity.)
  • striped bass
  • white perch
  • Atlantic croaker
  • summer flounder
  • adult female blue crabs
  • weakfish
• Length frequency charts comparing ChesMMAP data to VIMS Juvenile Fish Trawl Survey for the same time period.
  • summer flounder
  • weakfish
• Food habits charts for 2002 only.  Since these are based on one year's data only they should not be used except as being illustrative of the kinds of data this survey will produce in future years.
  • summer flounder
  • weakfish
• Fish age distributions are important assessment tools.  The age structure of the Chesapeake weakfish stock for 2002 are presented here, overall for the year, and for various sub-regions and time events.
  • Overall for the year 2002
  • For each ChesMMAP cruise (all regions)
  • For each ChesMMAP region (all cruises)
  • Length-frequency by age
  • Catch-curve analysis
