Title Composition of Atlantic Sturgeon in Rivers, Estuaries and in Marine Waters.

Abstract Tagging, genetic studies, and interceptory fisheries have revealed that Atlantic sturgeon make extensive coastal migrations. Tagging and interceptory fisheries provide evidence that Atlantic sturgeon are widely dispersed along the East Coast. Results of tagging studies and genetic analyses provide us with the information necessary to determine the origin of some of these Atlantic sturgeon and provide insights into migratory patterns. Insights provided by many tagging studies, however, are limited in that fish were captured and tagged in one river, but in many cases, this may not have been the actual river of origin for that particular fish. Only those fish tagged as spawning adults in the river or young of year (YOY) can be considered positively identified to river of origin. In August 2011, NER PRD staff held a workshop to examine available information to understand migration of Atlantic sturgeon and to determine a consistent approach for establishing the composition of Atlantic sturgeon present in rivers, estuaries and in marine waters. These consistent stock contribution percentages could then be used when section 7 consultations are conducted on activities funded, authorized/permitted or carried out by federal agencies in these areas.
