ABSTRACT
The intention of this study was to estimate population density, time of spawning, and fecundity of the turquoise darter (Etheostoma inscriptum) in Six Mile creek of the Clemson SC experimental forest. Population density estimates were conducted on 18 riffles within the lower 1,524 m of the creek starting 304.8 m above its confluence with Lake Issaqueena from January to April 2008. Density was determined using the Leslie Depletion method, and darters/m2 was calculated. Random point collection was performed From October 14 to November 13, 2008, and 301 specimens were measured and released to determine length frequency of the population. …

All Theses
Age and growth of Alabama shad Alosa Alabamae were estimated by examining scales and otoliths from 203 adult fish collected on their spawning run in the upper Apalachicola River from 2005 and 2006. Ages of Alabama shad ranged from 1 - 4 years. Scales and otoliths both gave similar age estimates. Age distributions from this study differed from those of previous studies for both males and females. Female Alabama shad, on average, were found to be larger than males at age 2 and age 3. Alabama shad demonstrated a positive correlation of length to fecundity, with fecundity estimates ranging from …
