RELATIONSHIPS BETWEEN ARTEMIA-MONICA LIFE-HISTORY CHARACTERISTICS ANDSALINITY

Relationships between Artemia monica life history characteristics and salinity were determined using data from four published studies and th ree experiments presented here. Salinity explained 40 to 93 percent of the variation in ten life history characteristics. Reductions in hatc hing success, survival, length, weight, ovigery, and brood size were o bserved as salinity increased from 76 to 168 g l-1. Inter-brood durati on, and time to hatching and reproduction were protracted as salinity was elevated. Salinity effects on life history characteristics appeare d to be gradual and continuous rather than exhibiting thresholds. The one exception was naupliar survival, which was constant between 76 and 133 g l-1 followed by a decrease above 133 g l-1.
