Abstract
The mucus layers of 30 gizzard shad (Dorosoma cepedianum) from the Lake Charleston side channel reservoir were sampled to identify what fungi or fungal spores were present. The fish sampled had a mean length of 171 mm, a mean weight of 41 g, and a mean age of 2.1 years. Hemp seed, fish scale, and polycell-gel substrates were examined, and four genera of fungi were identified. Fusarium was most frequently encountered, followed by Pythium, Allomyces, and Saprolegnia, respectively. Older fish (2.5 and 3.5 yrs) had a greater diversity of associated fungi than did younger fish (1.5 yrs), probably due to their benthic feeding habits and greater reproductive stress.
