Abstract:

Samples of 22 species of freshwater fishes were collected from 13 locations in Alabama. Two types of habitats were sampled, large impoundments and ponds. Analyses for phosphorus, calcium, magnesium, sodium, potassium, strontium, zinc, manganese, iron, copper, lead, chromium, nickel, cobalt, and cadmium were made on dried samples of these fishes. Per cent moisture and per cent ash were also determined. For bluegills (Lepomis macrochirus), mean amounts of Ca, Mg, Na, Zn, Mn, and Cd increased to the middle inch groups, then decreased through the larger inch groups. Mean amounts of K, Sr, Cu, Cr, and Ni generally decreased throughout the inch groups. Fe showed the greatest amount of variation. The remaining elements were fairly constant and showed no trends. For largemouth bass (Micropterus salmoides), mean amounts of Ca increased through the middle inch groups, then decreased through the higher inch groups. Mean amounts of Mg, K, and Mn decreased throughout the inch groups. Fe showed the greatest amount of variation. The remaining elements showed no definite trends.
