Threatened and Endangered Fish Species and Fish Species in Need of Conservation in Maryland

Fisheries Service is actively engaged in managing threatened and endangered species. Any finfish or shellfish species that is determined to be endangered by the federal Endangered Species Act are protected under Maryland law. The Endangered Species Act prohibits the unauthorized taking, possession, sale and transport of endangered species. In accordance with the Endangered Species Act, Maryland recognizes and works to conserve species listed as threatened or endangered by the federal government. DNR also works in cooperation with its partners to protect habitat valuable to the listed species. Additionally, the state has the ability through the Secretary of DNR to list a Maryland species as threatened or endangered given the following factors.

  1. The present or threatened destruction or modification of a species habitat or range
  2. Over exploitation for commercial, sporting, scientific, educational or other purposes
  3. Disease or predation

Species in Need of Conservation in Maryland

In order to ensure the continuation of sustainable fisheries and important ecological services, Maryland has designated species " in need of conservation". This designation may lead to additional conservation measures to enable the continuation of the species in Maryland waters. Species "in need of conservation" are species whose existence as part of the States natural resources is in jeopardy. Determination of a "species in need of conservation" can be obtained by information contained in stock status reports, commercial and recreational harvest reports and scientific literature among other sources. Local, state and private organizations work in cooperation with each other to effectively protect habitat vital to the designated species. In addition, listing a species as "in need of conservation" gives DNR the authority to develop and pass regulations to manage that species and obtain the desired management objectives.
