Question

how do oysters survive

Answer 1

Varies greatly depending on tidal height, salinity, disease prevalence and virulence, and predator and parasite prevalence and effectiveness. Oysters usually survive up to several years, but they have lived up to 20 years in captivity.

Answer 2

Most of the particles filtered by oysters are about 1-10 microns in diameter, about the same size as the single-celled phytoplankton (algae) that make up most of their diet. Filtration rate estimates range from 1.5 to 10.0 liters of water filtered per hour per gram (L h-1g-1) dry tissue weight, which is higher than the filtration rate of most other bivalves. Some of the particles filtered (including sediment and food) are ejected as “pseudofeces” without passing through the gut, because oysters need to ventilate their gills for more time than they need to feed.

Answer 9

The main predators on oyster larvae are other filter feeders, especially comb jellies (Mnemiopsis, Beroe). The main predators on adults in the Chesapeake Bay include cownose rays, black drum, and oyster drills. Crabs, worms, and boring sponges may also prey on adults.
