Between 1986 and 2008, the total economic value of the California mussel fishery was $14,499,845. Shell is a bluish-black color, often with eroded white valves and darker at margins. Mytilus californianus. Mytilus edulis and Mytilus californianus contain the same range of carotenoids. Range. Community Development and Persistence in a Low Rocky Intertidal Zone. Influence of Phytoplankton Concentration and Wave Exposure on the Ecophysiology of Mytilus californianus. 1996. gonochoric/gonochoristic/dioecious (sexes separate), "Status of the Fisheries Report 2008: Culture of Mussels (Mytilus spp.) 20. (Haderlie and Abbott, 1980). 2. The species MYTILUS EDULIS is the highly edible common mussel. The animal is pale orange. Mussel shell to about 130 mm long. California mussels (Mytilus californianus) are commonly found in large groups, covering rocks or other hard substrates (3).M. Size. to 5 inches (12.7 cm) Relatives. Mussels in the lower intertidal zones usually grow larger and more rapidly than those found higher up in the intertidal zone, because mussels in deeper water are immersed for longer periods and have longer opportunities to filter feed. b. P. ochraceus uses its tube feet to handle its prey. Rao, K. 1953. 355-411 in R Morris, D Abbott, E Haderlie, eds. Sacramento, CA: California Department of Fish and Game. Tidal Rhythmicity of Rate of Water Propulsion in Mytilus and its Modifiability by Transplantation. According to California State Tax records and the Department of Aquaculture Harvest Survey Database, the amount of mussels harvested in the wild is significantly smaller than what is harvested from aquaculture. Mussels such as Mytilus californianus or Mytilus edulis can attach to rocks and other surfaces using thin byssus threads, as shown in Figure 13.13. ), and large starfish (Pycnopodia helianthoides and Solaster stimpsoni), but little effect on mussels (Mytilus californianus and M. trossulus), dogwhelk snails (Nucella spp. and Mussel Fisheries. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

Mussels secrete protein fibers called byssal threads from a gland in the foot. Anterior end of shell is sharply pointed. Invertebrates. Veliger, 11, 378. Search in feature ("Culture of Mussels", 2001; "Status of the Fisheries Report 2008: Culture of Mussels (Mytilus spp.) chemicals released into air or water that are detected by and responded to by other animals of the same species, photosynthetic or plant constituent of plankton; mainly unicellular algae. I. Invertebrates Rocky Shores. This map was computer-generated and has not yet been reviewed. Environmental Conditions and Rate of Growth. Mytilus californianus‡ ‡ Indicates where communities were simplified to just the listed bivalve by physical removal of other species or by correcting for sediment and pelagic fluxes with a control. ), and large starfish (Pycnopodia helianthoides and Solaster stimpsoni), but little effect on mussels (Mytilus californianus and M. trossulus), dogwhelk snails (Nucella spp. A favorite prey of theseastarPisasterochraceous(picture). In California, Oregon, and the Olympic Peninsula, Mytilus californianus composed 15%–78% of the diet and was the most prevalent prey item at 8 of 10 sites . Gastropods, oysters, annelid worms, and even octopuses make their homes in and around the mussel bed, exploiting the interstitial spaces between the mussels as refuges from predators. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis. They also feed on chitons, limpets, snails, barnacles, echinoids, and even decapod crustacea. Note: the time scale of each image is slightly different for best visualization of HR; furthermore, the graph units (i.e. Bodega Harbor, California (Laboratory) 1.64: 59.1: 0.6: This study: Mytilus edulis: Narragansett Bay, Rhode Island: 1.55: 84.4: 6.3 Natural History.
