The effect of salinity and temperature on Olisthodiscus luteus Carter has been examined to across the relative importance of these factory on dynamics of natural population. A salinity range 2–50% was observed with increased tolerance to low salinity (<5%.) at higher temperature (20–30°C). Slinities at 4–5%. Had densities of 103 cells/ml−1, and growth >0.5 division day−1 at temperature of 15–30°C higher salinities (5–50%.) variable but distinct optima for density, growth and motility were observed
5, 10 and 30°C. Density and motility showed no clear optima from 10–10%.15–25°C where maximum growth rates >1.0 division/day−1 were common. Temperature increased from (0.5–1.9 division. Day−1) and increases of three orders of magnitude (102−103) for maximum densities. Temperature optima 20°C for growth 5–35%. And 25°C for >40%. were observed. The implications of these findings to natural populations of O. luleus are discussed.
