Marine invertebrates such as sea cucumbers are becoming increasingly important in aquaculture to meet the growing demand for sustainable protein and as a source of marine based pharmaceuticals. Like other aquatic animals, sea cucumbers raised in aquaculture facilities experience stress that can potentially have a significant impact on their disease resistance, growth and development. To study the impact of potentially aquaculture related stressors namely, low salinity and handling, a variety of physiological and immunological tests were conducted on the hemolymph of the Giant California sea cucumber Parastichopus californicus. These tests included total and differential cell counts, packed coelomocyte volume, hemal fluid protein, phagocytic capacity, and lytic activity of immune cells. Based on the results obtained, sea cucumbers kept in handling and salinity stress conditions showed no significant differences from those kept in control conditions. These results could indicate that the sea cucumber is a good candidate for aquaculture, as it would seem to not be stressed by lowered salinity or by handling. As sea cucumbers are increasing in importance for both human consumption and production of pharmaceuticals, this is result could encourage the increased culturing of this species.
