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.

2016 Shark Monitoring

New to the VIMS Fisheries website:  Catch maps of the VIMS Longline Survey.


The VIMS Longline Survey is managed by the Multispecies Research Group.

VIMS Longline Survey, September 2014

The Virginia Shark Monitoring and Assessment Program (VASMAP), also known as the VIMS Longline Survey includes an adult sampling component and two juvenile components.  All three surveys run once a month throughout the summer and the adult survey runs an extra cruise in September.  Here are the latest catch rates from the September 2014 adult survey.  Learn more about VASMAP.

Ever wonder how we tag juvenile sharks?

The Cooperative Atlantic States Shark Pupping and Nursery (COASTSPAN) survey is an ongoing investigation of known and putative shark nursery grounds along the east coast of the United States. The primary objectives of the COASTSPAN survey are:

  • First, to determine the location of shark nursery grounds along the U.S. East Coast and describe their species composition and habitat preferences using presence/absence data.
  • Second, to determine the relative abundance, distribution and migration of sharks utilizing these nursery grounds through longline and gillnet sampling and mark-recapture data.


Shark Survey Tag Types:

Hallprint Nylon dart tags are used for sharks < 100 cm TL tagged below the dorsal fin along the lateral line

Blue Roto tags are used to double tag sharks in the COASTSPAN survey. Sharks < 100 cm TL are tagged in the dorsal fin

Hallprint Stainless steel head dart tags for sharks > 100 cm TL tagged below the dorsal fin along the lateral line

Yellow Roto tag used to double tag sharks in the COASTSPAN survey. Sharks > 100 cm TL are tagged in the dorsal fin
