Connecting Rivers In The Penobscot Watershed, Catherine Schmitt

Maine Sea Grant Publications

Across Maine, communities and land owners are reconnecting rivers and streams by improving road crossings, fixing broken culverts, and removing dams and other barriers. There are many reasons for doing this work, including preventing costly repairs associated with flooding and washouts, enhancing water quality, increasing wildlife habitat, and restoring fish populations. Connecting Rivers explores some of the ways that streams connect inland lakes and forests and the sea. This second fact sheet in the series provides an overview of the motivations for and benefits of restoring fish passage, and includes a map of dam removals and other restoration actions in …

Penobscot River Restoration, Catherine Schmitt

Maine Sea Grant Publications

BETWEEN THE HEAD of tide above Bangor to where it widens into the bay at Searsport, the Penobscot River shifts from a flowing freshwater waterway banked by cedar and pine to a brackish, wave-lapped marsh with a rocky shoreline. In this estuary, salt concentrations fluctuate as the winds and tides push sea water and sediments back and forth. The estuary and the river that feeds it have taken on a new character recently, and have become an international example of watershed restoration. Despite two centuries of intensive timber harvesting and pulp and paper manufacturing, and the construction of hundreds of …

Connecting Rivers For Healthy Ocean Fisheries, Catherine Schmitt

Maine Sea Grant Publications

Across Maine, communities and land owners are reconnecting rivers and streams by improving road crossings, fixing broken culverts, and removing dams and other barriers. There are many reasons for doing this work, including preventing costly repairs associated with flooding and washouts, enhancing water quality, increasing wildlife habitat, and restoring fish populations. Connecting Rivers explores some of the ways that streams connect inland lakes and forests and the sea. This first fact sheet in the series focuses on connections between populations of migratory river fish (alewives and blueback herring) and groundfish (e.g., cod).

Rapid Response Plan For Management And Control Of The Chinese Mitten Crab, Northeast United States And Atlantic Canada, A. Eberhardt, J. Pederson, B. Bisson

Maine Sea Grant Publications

The Rapid Response Plan for Management and Control of the Chinese Mitten Crab is intended to guide efforts to mitigate the further introduction and spread of the Chinese mitten crab in the northeastern United States and Canada. Due to the unique challenges of invasive species introductions to marine and coastal ecosystems, the mitten crab and other existing and potential marine invasive species are more difficult and often more costly to manage or control than freshwater aquatic or terrestrial invasive species. These challenges include ecosystem connectivity across vast geographic areas, ocean currents and tidal influence, and shipping- and ballast-related vectors for …

In Their Own Words: Fishermen's Perspectives Of Community Resilience, Teresa R. Johnson, Anna Henry, Cameron Thompson

Maine Sea Grant Publications

Maine’s fishing communities are experiencing the cumulative effects of fish stock depletion, state and federal regulations, coastal development and demographic changes, and rising fuel and energy costs.

Legally, federal fisheries managers must minimize adverse economic impacts of fishery regulations on fishing communities, yet too often data with which to do this are insufficient (Ingles and Sepez 2007). For example, National Standard 8 of the Magnuson Stevens Fishery Conservation and Management Act, the federal legislation governing the management of marine resources in the U.S., requires that managers “take into account the importance of fishery resources to fishing communities” and “provide sustained …
