Brook Trout Research in Maryland

Brook Trout Research in Maryland

The Brook Trout Program is committed to staying on the cutting edge of the current science available pertaining to eastern brook trout. Keeping up to date with the information that is available allows us to most effectively manage this species of greatest conservation need (GCN). Sometimes, however, there are gaps in the literature that leave questions unanswered or there are questions specific to Maryland waters that need to be addressed. In these cases, our brook trout staff biologists conduct research to more fully understand our only native salmonid.

The following is a list of final reports, often published, generated by the Maryland DNR Fisheries Service. Please click the link to see a copy of the final report.

Relationship Between Wetlands and Mercury in Brook Trout (2005) - Investigation into mercury in brook trout and how it relates to wetland presence in the system. http://www.umces.edu/relationship-between-wetlands-and-mercury-brook-trout​​

Estimating Space Requirements and Extinction Risk for Maryland Brook Trout (2006) – Research geared to determining the minimum population sizes needed to sustain long term brook trout populations and genetic viability.

Poplar Lick ORV Trail Investigation (2006) – Field investigations of ORV use on water quality and invertebrates in Poplar Lick. Here is the final report - Poplar Lick ORV Investigation.

Re-Inventory of Targeted Brook Trout Populations in Western Maryland (2007) – Selected Brook trout populations were re-surveyed from initial work done in the 1980's.

Investigation of the Feasibility of Propagation of Wild Brook Trout in a Small, Closed System as a Potential Management Tool for Conservation and Restoration Projects (2009) – Joint project with Frostburg State University to attempt to develop a small, closed system aquaculture facility for wild Brook trout production.
