2007 Status Review of Atlantic sturgeon - National Marine Fisheries ...

List of Tables
Table 1. Historic and current spawning status of Atlantic sturgeon throughout its
natural range, and current uses of the riverine habitat……………………………………... 140
Table 2. Atlantic sturgeon pair-wise comparisons among sampled populations,
indicating significant or visually interpreted differences between populations……………. 141
Table 3. (A) Statistical significance of FST (lower diagonal) and Monte-Carlo-based X 2
(upper diagonal) comparisons of mtDNA control region haplotype frequencies among
Atlantic sturgeon collections. All p-values, corrected using sequential Bonferroni
methods, were significantly different except those noted in bold font (Wirgin,
supplemental data 2006). (B) Statistical significance of FST (lower diagonal) and allele
frequency heterogeneity pair-wise comparisons of 12 locus nDNA markers among
Atlantic sturgeon collections. All p-values, corrected using sequential Bonferroni
methods, were significantly different (King, supplemental data 2006)……………...…….. 142
Table 4. Analysis of Molecular Variance (AMOVA) results employing 12 locus nDNA
markers and nine Atlantic sturgeon populations (King, supplemental data 2006).…….…. 143
Table 5. Analysis of Molecular Variance (AMOVA) results from 12 Atlantic sturgeon
populations using mtDNA sequence data (Wirgin, supplemental data 2006)...…………… 144
Table 6. Classification success rate for Atlantic sturgeon to their natal river and
distinct population segment (DPS) using both 7 and 12 locus nDNA microsatellites.
Top: a classification matrix, in which YOY or adults were exclusively used in the
analysis employing a 12 locus nDNA marker. Bottom: a classification matrix, in
which YOY or adults were exclusively used in the analysis employing a 7 locus
nDNA marker………………………………………………………………………………. 145
Table 7. The percentage of riverine habitat (rkm) available to Atlantic sturgeon in
each river system, ranging from the mouth of the river to the fall line or historic
spawning grounds. Estimates of river kilometers were based on GIS mapping and
reference points provided by Oakley 2005 and other sources. However, river
kilometers is only an estimate of habitat availability and should not be confused as a
reference to habitat suitability as many factors can reduce the quality of this available
habitat (e.g., impeded by water flow, dredging, water quality and other similar factors)…. 146
Table 8. Atlantic sturgeon captured by dredge type as reported by the U.S. Army
Corps of Engineers for the U.S. East Coast from 1990 – 2005. Reports include only
those trips when an observer was on board to document capture, and numbers do not
reflect all sturgeon captures………………………………………………………………... 147

East Coast published by the U.S. Environmental Protection Agency (2004) that grades
coastal environments. Northeast Region is Maine south through Virginia; southeast
