Eustarine Biota: 2/20/19 * Shrimp = juveniles Live in estuaries. - Adults will go out to the ocean. to live and. lau eggs. All of our shrimp is farmed. * Fish and oligochaete • Polychaetes are common on mudflats * Oysters and mussels - lower segment * Migration through. Estuaries Eels and Salmon. Because Salinity is so variable, there exist: Osmoregulators controls your Salinity. Osmo conformer: conforms to the environment. * Temperature and availability influence species distrib. Some Fish have strategies in order to survive an with a varying salinitu or tide. area However, Salinity is not the deteriminant of abundance. Instead, the book mentions that habitat is a determinant. * There is a consequence with the amount of river inflow. Estuaries generally have high abundance • There's a lot of invertebrates too. Estuaries also serve as a good nursery * They typically have low DO. . And low primare production Most of the energy. comes from detritus material. Lo eaten by oligochaetes and polychaetes. * Animals usually keep the isotopic signatures as plant and can be used to detect whats eaten. the Biodiversity in Estuaries: Least diverse in middle seg. Older ones are more diverse. Hyposaline Hypersaline. Lagoon Bay vs Lagoon: → Depends on the interac- tion with the ocean.
