Abstract
Tests were conducted using continuous exposure in shallow water at levels of total dissolved gas pressure ranging from 110-140% of barometric pressure (hyperbaric pressure = 103-410 g/sq cm). Both times to 20% and to median mortality were determined on several life stages of Pacific salmonids (Oncorhynchus and Salmo) and Largemouth bass (Micropterus salmoides). Factors which influenced time to death included genera, life stage, acclimation temperature, activity level, sex and body size. Mortality curves were typically skewed to the right. Gross pathology of gas bubble disease was described relative to these experiments. Long-term (3-month) continuous exposure of adult spring chinook salmon to 110% saturation had no readily apparent adverse impact on the fertilization and hatching of their eggs.
