The ridgeback shrimp, Sicyonia ingentis, lives off of the west coast of North America along the shorelines of California, and Baja California and is a source of both revenue and food for residents of the area. The reproductive abilities of S. ingentis are crucial to the survival of the species. Vitellin (Vn) is an egg yolk protein found in the ovaries of reproductive shrimp and can also be seen in their hemolymph. This study examines temperature as a factor influencing the reproductive fitness of S. ingentis. The synthesis of Vitellin is a good indicator of reproductive fitness and the concentrations of the Vn protein can be found using an ELISA (enzyme linked immuno-sorbant assay). The difference in temperature from the cold water tank environment (11 C) to the warm water tank environment (14 C) can simulate the effects if global warming continues to persist; showing the harmful effects that this increase in temperature can have on marine species that depend on the cold ocean temperatures for survival.
