Fisheries Research

Restoration and Conservation

Fisheries Section biologists study fish species to restore and conserve their populations. This work includes the study and protection of endangered species and species of conservation concern, such as rare minnow species like the Ironcolor Shiner, Bridle Shiner, Rio Grande Silvery Minnow, and migratory species, such as American Eel and American Shad. We have partnered and worked in collaboration with conservation-minded groups such as The Nature Conservancy, The National Park Service, and many state government agencies.

Invasive Species

Fisheries Section Biologists study the effects of invasive species on aquatic resources, biodiversity, and species of concern. We are particularly interested in the implications of invasive species for future management. Some invasive species of recent focus include Northern Snakehead, Flathead Catfish and Asian Swamp Eel.

Industry and Pollution

Fisheries Section biologists and other Academy scientists have routinely evaluated the effects of industry on fish and fish communities throughout the United States. We have researched the effects of natural gas drilling on fishes and assessed toxins in fish to aid in regulation setting and understanding of effects of pollutants. Additionally, studies have included assessing water quality standards and species requirements, such as the dissolved oxygen concentration requirements of aquatic species in the Delaware Estuary. Understanding and assessing emerging contaminants and industries are of particular interest.
