The subject of artificial reef research and development has expanded over the past several decades to address issues related to their function and utility relative to fishery management as well as ecological performance. Because of the potential that artificial reefs may have in the future of environmental management, a symposium and a conference were held in 2017 on the subject. The symposium, entitled “Marine Artificial Reef Research and Development: Integrating Fisheries Management Objectives,” was held August 22–23, 2017 in Tampa, Florida (USA) during the 147th Annual Meeting….Read more

In recent decades, aquaculture nutrition research has made major strides in identifying alternatives to the use of traditional marine‐origin resources. Feed manufacturers worldwide have used this information to replace increasing amounts of fish meal and fish oil in aquafeeds. However, reliance on marine resources remains an ongoing constraint, and the progress yielded by continued unidimensional research into alternative raw materials is becoming increasingly marginal….Read more

Within the western Great Lakes (WGL) region of the USA (Michigan, Minnesota, and Wisconsin), the ecological impact that the North American beaver Castor canadensis has on coldwater streams is generally considered to negatively affect salmonid populations where the two taxa interact. Beavers are common and widespread within the WGL region, while coldwater streams that support salmonid populations are scarcer landscape features; as such, all three states currently prioritize…Read more
