| dc.description.abstract | Developing embryos of near-shore marine organisms are subject to freshwater influx, which exposes them to low salinity conditions. This experiment tracked embryo development in kelp crabs (Pugettia producta) exposed to three salinity treatments [32, 23, and 9 parts per thousand (ppt)]. Data from this experiment indicate that the rate of embryo development is not affected by salinity within the range of 9 – 32 ppt. Survival, determined by presence of heart beats, was highest in 32 ppt. No embryos survived after 24 hours in the 9 ppt. treatment. In addition to salinity testing, rates of embryo development were compared between the embryos cultured in dishes (in vitro) and those allowed to develop in the abdomens of live adult females (in vivo). The results indicate that embryos develop slightly faster when raised in vivo rather than in vitro, but that embryos can be reared successfully in vitro without the use of antibiotics. | en_US |
