An Analysis Of The Heavy Metal Content Of The Scales Of Several Fishes In Southwestern Kentucky, Thomas Dahl

Masters Theses & Specialist Projects

Scales of the stoneroller, Campostoma anomalum (Rafinesque), common shiner, Notropus cornutus (Mitchill), and the bluntnose minnow, Pimephales notatus (Rafinesque) were analyzed by means of atomic absorption spectrophotometry to determine levels of cadmium, calcium, copper, iron, lead, manganese, nickel and zinc. Metal concentrations were determined seasonally and relationship established between scale metal content and environmental water metal levels.

Calcium, iron manganese and zinc were found in all samples analyzed. Cadmium, copper, lead and nickel were not observed in measurable quantities.

Metal concentrations varied interspecifically, but most showed little fluctuation in response to increased metal content of the water. Elemental composition of …

Spatial Distribution & Temporal Occurrence Of Rotifers In The Main Pool & Tailwater Of Barren Lake, Kentucky, David Abel

Biology Graduate Theses

A study of the spatial distribution and temporal occurrence and diversity of rotifers in relation to certain chemicophysical parameters was conducted in Barren Lake, Kentucky, a flood control lake, from January, 1970, through January, 1970. Paired samples were collected from six depths in the main pool area of the reservoir and from an automatic plankton sampler installed in the tailwater area where, from April through September, the effluent was derived from the upper 3 m of the pool . Diel studies were conducted in April, July, 1970, and January, 1971.

Barren Lake began to stratify in late April, was completely …
