Reproduction overhead is not idicated, since it is payed at conversion of buffer to eggs/foetuses. Mytilus californianus - this mussel is a filter feeder, feeding on plankton. J. [citation needed] However, mortality in intertidal open coastal environments is often high, resulting from battering from driftwood and other debris, wave pounding, predation, desiccation, and disease. Although two species of Mytilus occur within this region (M. californianus and M. galloprovincialis) the California mussel, M. californianus is by far the most abundant Mytilus species at all the open coast rocky intertidal sites (Johnson and Geller, 2006). Benthic algae and other primarily freeliving organisms often act as facultative epibionts, colonizing the secondary space afforded by the mussel's large surface area (Paine 1976, … An analysis of differences in size, growth rate, age at first reproduction, life span, mode of reproduction, niche and habitats between these two species demonstrates that their life history strategies are different in several important ways. The beaks of the shell are often eroded. Description: The California mussel (Mytilus californianus) is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. All rights reserved.

Geographic Range. For mussels of similar initial length (24-39 mm), M. californianus grew 24 mm vs. 14 mm for M. edulis from 27 April to 25 September, 1988, and contained over twice as much dry meat as M. edulis. Le manteau est alors orange chez la femelle, blanchâtre chez le mâle. Spawning and settling season of the mussel. Spawning habits of the mussel Mytilus californianus with notes on the possible relation to mussel poison. native; Habitat. The presence of Glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and the transaldolase-transketolase system has been demonstrated in Mytilus californianus by Bennett and Nakada (1968). California mussels are found clustered together, often in very large aggregations, on rocks in the upper intertidal zone on the open coast, where they are exposed to the strong action of the surf. Una ning gihulagway ni Conrad ni adtong 1837. La ponte est fatigante pour lanimal qui perd alors beaucoup de poids : il doit après se mettre au repos et refaire des réserves. Le taux de reproduction est élevé car une moule peut produire chaque année 5 à 12 millions dœufs, en plusieurs fois.

La ponte a généralement lieu de mars à octobre mais peut être déclenchée par des variations de température ou de quantité de nourriture. While these mussels are usually edible, care needs to be taken, because during times of red tide in any given locality, California mussels may contain harmful levels of the toxins which can cause paralytic shellfish poisoning. Given the right circumstances, California mussels can grow up to 200 mm (8 inches) in length and may live for more than 20 years.

Alkaline conditions were necessary to make the animals responsive to the spawning stimulus provided by the algae. There have been recognized four major stages in the reproductive cycle of Mytilus edulis : … Life cycle: Egg develops into the first free-swimming larval stage (trocophore) within 4 to 24 hours, afterwhich it develops into a veliger larvae within 24 to 48 hours.
