The reproductive cycle of Limnoperna fortunei (Dunker, 1857) (Mytilidae) from a neotropical temperate locality

Limnoperna fortunei is a dioecious, freshwater mytilid native to Asia. The reproductive biology of this invasive species is analyzed for the first time in its neotropical habitat. About 35 specimens were processed monthly using standard histological techniques (sections ~ 6 μm thick). The size of mu...

The reproductive biology of this invasive species is analyzed for the first time in its neotropical habitat. About 35 specimens were processed monthly using standard histological techniques (sections ~ 6 μm thick). The size of mussels at sexual maturity varied seasonally. From June to October, sex differentiated at 5-6 mm shell length (SL), and from March to May at 7-10 mm SL. Adult males contained mature sperm throughout the year. Mature oocytes measured 70-100 μm. Three main spawning events occurred in May to July 1993, April to May 1994, and October 1994. Two partial spawnings were observed in September to October 1992 and December 1992 to January 1993. No spawnings were recorded from October 1993 to February 1994 and from June to October 1994. Oocyte proliferation was continuous and immature oocytes were recorded throughout the year. The population appears to have continuous reproduction with peaks of maturing activity related to temperature changes. Fil:Penchaszadeh, P. Universidad de Buenos Aires.
