The lake sturgeon (Acipenser fulvescens) was once widely distributed
among the Great Lakes, Hudson Bay, and Mississippi River drainages, but
now is conferred protected status in each of the 20 states in which it is
a native species. The success of lake sturgeon conservation and
restoration programs requires the identification and protection of
preferred habitat types for all life history stages. Equally important is
the identification of factors that make these habitats suitable for lake
sturgeon. This study will examine the apparent habitat partitioning
between juvenile and adult lake sturgeon in the St. Lawrence River.
Specific objectives are to determine the preferred prey types of juvenile
and adult lake sturgeon, and to examine the relationship between feeding
characteristics of juvenile and adult lake sturgeon and the benthic
invertebrate community within their preferred habitats. |
