Abstract

Mortality and Labyrinthomyxa marina levels were measured in the American oyster, Crassostrea virginica, following exposure (test) and nonexposure (control) to a 100% water-soluble fraction (WSF) of south Louisiana crude oil in a closed seawater system. Market size oysters (6.6cm) with weighted incidences of 1.9 (experimental IA), 0.4 (experiment IB) and 0.6 (experiment II) were collected from an oyster reef known to harbor a high percentage of L. marina infected oysters. The wide range of weighted incidences between experiments is a result of seasonal variation with lower levels present in oysters collected in winter months. Control and test oysters were held at varying temperatures: 16, 20, 22, 24, and 28 C. Comparison of the test and control mortalities indicated the effect of the WSF of south Louisiana crude oil on a diseased oyster population. Comparison of test and control oyster L. marina levels indicate the effect of the WSF of south Louisiana crude oil on L. marina.
