Atlantic Salmon Recovery Plan

To help identify and guide species recovery needs, section 4(f) of the Endangered Species Act directs the Secretaries to develop and implement recovery plans for listed species. A recovery plan must include (1) a description of site-specific management actions necessary to conserve the species; (2) objective, measurable criteria that, when met, will allow the species to be removed from the endangered and threatened species list; and (3) estimates of the time and funding required to achieve the plan’s goals.

Atlantic Salmon Recovery Proposal Guidelines

(Note: This is not a funding proposal). This is an interim template for proposing Atlantic salmon related projects within the Gulf of Maine DPS. Proposals may be required if a project proponent is requesting Atlantic salmon to conduct a study, or requesting agency support or resources. The GOM DPS is divided into 3 Salmon Habitat Recovery Units (SHRUs). Each SHRU is managed by a team under the Atlantic salmon program's Collaborative Management Strategy (CMS). Project proponents should first discuss their project with the appropriate SHRU Team or, if a project is not specific to a SHRU, the project proponent should first contact that CMS's administrative coordinator. For information on project proposals contact: Dan Kircheis at (CMS administrative Coordinator)

Workshop Report: Diadromous fish as marine prey


Over the past 20 years, efforts to restore diadromous fish in Maine’s river systems have led to significant increases in run size for many species, namely river herring. As the abundance of river herring populations have increased, it has become more pertinent to understand role of river herring as prey for marine predators in the Gulf of Maine (GoM). To assess our current understanding of this ecological connection, we organized a workshop for scientists who are actively researching the role of diadromous fish as prey in the GoM. Over two days, scientists shared current research and preliminary results to foster discussion on the “state of the science”. Preliminary results from Maine Department of Marine Resources trawl survey and traditional diet sampling indicate that river herring abundance is variable at spatial and temporal scales in the nearshore GoM, with indications of overall increased abundance in recent years. Despite the perceived increases in river herring abundance, river herring detection in diets has been relatively low among the small number of sampled marine predators. Of these sampled marine predators are Atlantic cod (Gadus morhua), a groundfish with low abundance and truncated size distribution. However, river herring have recently been detected for the first time in the diet of Atlantic Bluefin tuna (Thunnus thynnus) sampled in the GoM. Further, stable isotope analysis is proving to be a powerful tool for detecting the presence of freshwater prey contributions to the diets of marine predators at a broader temporal scale than traditional diet sampling. Participants discussed potential synergies within these investigations and committed to a future meeting to explore these topics further and formalize connections by coordinating sample collection, comparing methodologies, and sharing results. This suite of studies is slated to continue and therefore strengthen our understanding of the role of diadromous fish, especially river herring, as marine prey.
