Fall 2018 NEAMAP Food Webs

Our diet analysis lab was extremely productive over the winter!  We finished up the fall NEAMAP samples in record time, leaving a large vacant spot in the lab awaiting the return of the March ChesMMAP cruise and more stomachs.  Discover what we saw in the fish stomachs, learn about who was eating whom, and explore the structure of food webs in the nearshore habitat of the US mid-Atlantic coast.

May 2018 ChesMMAP Catch Maps

CaptureThe first catch maps of the 2018 MRG field season are here! ChesMMAP encountered a good diversity of species last month at our 80 stratified random stations including 32 finfish species, 5 elasmobranch species, 10 invertebrate species, and 5 species categorized as habitat.

Kingfish, weakfish, and harvestfish were caught at 20 to 30 percent of the stations; northern puffer, striped burrfish, Atlantic menhaden, bluefish, Atlantic croaker, and spotted hake were caught at 10 to 20 percent of the stations.

Use the link to the map to explore locations where each species was caught.

Scientists on board were: J. Eckert (Cheif), J. Gartland, J. Gregg, and L. Jenner. The R/V Bay Eagle was operated by: J. Olney Jr (Captain) and K. Mayer (Mate).

MRG Map Wrap Up 2017

The ChesMMAP and NEAMAP trawl surveys and Longline surveys field crews are hanging up their boots for 2017.  Thanks to the hard work of the MRG crew, another year of fish monitoring is over, complete with 114 total days and 561 total person-days in the field.  Check out the map links below for the year-end wrap-up of survey results.

July 2017 ChesMMAP Water Quality Maps

See the side by side comparisons of the Chesapeake Bay bottom dissolved oxygen, water temperature, and salinity.  During the July cruise, Chief Scientist Dustin Gregg noted higher catch productivity for a number of species along the Virginia Eastern Shore of the Bay.  Check out the dissolved oxygen map to see why this was likely the case.  An area of higher oxygen where the higher catches were noted.


July 2017 ChesMMAP Catch Maps

Here is your 2017 ChesMMAP field season update! The July cruise is complete with a lot to report, including unusually high catch numbers and diversity for Chesapeake Bay mid-summer. We’ve seen catch numbers for our Sciaenids gradually increasing recently, and Atlantic croaker, spot, kingfish, and weakfish catches continue to show improvement. Also in abundance were harvestfish, Northern searobins, and a high diversity of stingrays. Some juvenile sandbar sharks even made an appearance. According to Chief Scientist, Dustin Gregg, higher catches and diversity were seen particularly along the Virginia Eastern Shore side of the Bay (spadefish, Northern puffer, striped burrfish, bluntnose stingray).

Herrings and menhaden displayed typical low summer catches, but white perch catches were also limited to just a couple of stations as well.

Habitat such as dead man’s fingers (a bryozoan), hydroids, redbeard sponge, and sea squirts were widespread in lower bay catches.

Stay tuned for July ChesMMAP water quality updates and results of the truncated spring NEAMAP cruise.

May 2017 ChesMMAP Water Quality Maps

More new web map features for 2017! The ChesMMAP water quality maps are now compiled in a streamlined map gallery. In addition to the link below, the GIS Maps page on our website has a link to the water quality map gallery where you can view bottom dissolved oxygen, water temperature, and salinity maps for each cruise side-by-side in a single view. Feel free to comment with any questions or how the gallery could be improved!


May 2017 ChesMMAP Interactive Catch Maps

Now reporting the most recent ChesMMAP catch map. Our interactive map is now more comprehensive, including incidental catches of invertebrates and habitat encountered. The crew noted higher than usual catches of white and channel catfish in the upper reaches of the Bay. In addition, spot catches were higher than in recent years, and kingfish continue to rally.
