Filamentous Fungi Present In The External Mucus Of Gizzard Shad (Dorosoma Cepedianum), Kenneth C. Stetina

Masters Theses

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.
