The Effects of Temperature and Desiccation on Surf Smelt (Hypomesus pretiosus) Embryo Development and Hatching Success: Preliminary Field and Laboratory Observations
we conducted a field study to investigate possible environmental factors influencing surf smelt (Hypomesus pretiosus) egg mortality at eight beaches on the southern Strait of Georgia, British Columbia (B.C.), Canada. Egg mortality was variable, but was positively correlated to air temperature and increased in June and July when maximum temperature was approximately 30°C. In June 2003, we conducted a preliminary laboratory study to investigate the effects of desiccation on surf smelt egg mortality. Results suggested a threshold RH requirement of 80 – 93% for successful development and hatching of surf smelt embryos. Moisture and temperature interact to condition RH in the
intertidal zone. Shade vegetation, which can cool air temperature in the supralittoral zone, may be important for some populations of surf smelt. Further investigations are required to confirm the findings.
