Some Biological Properties of Date Mussels, Lithophaga Lithophaga L., 1758 (mytilidae) in the Gulf of Antalya
This research has been carried out to investigating of some biological aspects of date mussels, Lithophaga lithophaga distributing in Gulf of Antalya, in February 2015 – January 2016. The samples were used to determine length and live weight frequency distributions (nonlinear regression using the allometric function), size (length, breadth, thickness) – size relationship (linear regression). Th...
متن کاملGill Development and its functional and evolutionary implications in the blue mussel Mytilus edulis (Bivalvia: Mytilidae).
Study of gill development in bivalve larvae and postlarvae provides information on the evolution of this organ and feeding mechanisms of early stages. Scanning electron microscopy was used to document the development of the filibranch homorhabdic gill in hatchery-reared larval, postlarval, and juvenile Mytilus edulis. Four key stages were identified during gill development: (1) transfer of the ...
متن کاملParasites of the mangrove mussel Mytella guyanensis (Bivalvia: Mytilidae) in Camamu Bay, Bahia, Brazil.
This contribution reports the parasites found in the mangrove mussel Mytella guyanensis in Camamu Bay, Bahia, Brazil. Samples were collected monthly from September 2006 through October 2007. A total of 460 individuals were collected, fixed in Davidson's solution, and processed by standard histological techniques, and the sections were stained with Harris hematoxylin and eosin (H&E). The water t...
متن کاملEvidence for methylotrophic symbionts in a hydrothermal vent mussel (bivalvia: mytilidae) from the mid-atlantic ridge.
Symbioses between chemolithoautotrophic bacteria and the major macrofaunal species found at hydrothermal vents have been reported for numerous sites in the Pacific Ocean. We present microscopical and enzymatic evidence that methylotrophic bacteria occur as intracellular symbionts in a new species of mytilid mussel discovered at the Mid-Atlantic Ridge hydrothermal vents. Two distinct ultrastruct...
متن کاملMini-review: Distribution of the Mediterranean Mussel Mytilus Galloprovincialis (bivalvia: Mytilidae) and Hybrids in the Northeast Pacific
The non-native Mediterranean mussel Mytilus galloprovincialis is broadly established in the northeast Pacific. Until recently, the coast north of Humboldt Bay, California, USA, was not considered a major zone of sympatry and hybridization with the native sibling species M. trossulus. However, M. galloprovincialis has been introduced in Washington, USA, and British Columbia, Canada, for aquacult...
