  • Atlantic Salmon Alert
    ALERT FOR ATLANTIC SALMON IN SOUTHEAST ALASKA WATERS Please report any observations of this non-native species to the nearest ADF&G office. Over the past few years, ADF&G has verified harvests of Atlantic salmon in Southeast Alaska salt waters. Atlantic salmon are not native to the Pacific Ocean; they are raised in areas along the West Coast outside of Alaska, and their presence in Southeast Alaska waters is biologically undesirable. Anglers have reported catching Atlantic salmon in several of Southeast Alaska's freshwater systems. Alaska sport fishing regulations do not limit harvest of Atlantic salmon, but if you catch one, you can help us determine their status by bringing the entire fish to the nearest ADF&G office for biological sampling.

These species are managed in the Atlantic Ocean, including the Caribbean Sea and Gulf of Mexico, by the National Marine Fisheries Service (NOAA Fisheries) under the authority of the Secretary of Commerce, with consideration for the domestic and international aspects of these fisheries. Management of these species is outlined in the 2006 Consolidated Atlantic Highly Migratory Species Fishery Management Plan (2006 Consolidated HMS FMP) and its amendments. NOAA Fisheries frequently modifies the regulations to meet fishery management goals and requirements. This guide is intended to provide a plain language summary of how to comply with the HMS regulations for Atlantic tunas, swordfish, sharks, and billfishes. Important regulatory changes and corrections since previous versions of the Compliance Guide were published include, but are not limited to: Effective Date Description of Change October 2018 Measurement of Bigeye and Yellowfin Tuna Damaged through Predation by Sharks and Other Marine Species: If a bigeye and/or yellowfin tuna carcass has been damaged (i.e., bitten) by a shark or another marine species, it may be retained and landed if the remainder of the fish meets the minimum size of 27 inches (69 cm).

  • Invasive Catfish Management Strategy August 2020
    Invasive Catfish Management Strategy August 2020 A team from the Virginia Department of Game and Inland Fisheries uses electrofishing to monitor invasive blue catfish in the James River in 2011. (Photo by Matt Rath/Chesapeake Bay Program) I. Introduction This management strategy portrays the outcomes of an interactive workshop (2020 Invasive Catfish Workshop) held by the Invasive Catfish Workgroup at the Virginia Commonwealth University (VCU) Rice Rivers Center in Charles City, Virginia on January 29-30, 2020. The workshop convened a diverse group of stakeholders to share the current scientific understanding and priority issues associated with invasive catfishes in Chesapeake Bay. The perspectives shared and insights gained from the workshop were used to develop practical, synergistic recommendations that will improve management and mitigate impacts of these species across jurisdictions within the watershed. Blue catfish (Ictalurus furcatus) and flathead catfish (Pylodictis olivaris) are native to the Ohio, Missouri, Mississippi, and Rio Grande river basins, and were introduced into the Virginia tributaries of Chesapeake Bay in the 1960s and 1970s to establish a recreational fishery. These non-native species have since spread, inhabiting nearly all major tributaries of the Bay watershed. Rapid range expansion and population growth, particularly of blue catfish, have led to increasing concerns about impacts on the ecology of the Chesapeake Bay ecosystem. 1 Chesapeake Bay Management Strategy Invasive Catfish Blue and flathead catfishes are long-lived species that can negatively impact native species in Chesapeake Bay through predation and resource competition. Blue catfish are generalist feeders that prey on a wide variety of species that are locally abundant, including those of economic importance and conservation concern, such as blue crabs, alosines, Atlantic menhaden, American eels, and bay anchovy.
