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 montly using standard histological techniques (sections - 6um thick). The size of mussels at sexual maturity varied seasonally. From June to october, sex differentiated at 5-6 mm shell lenght (SL), and from March to May at 7-10mm SL. Adult males contained mature sperm throughout the year. Mature oocytes measured 70-100 um. Three main spawning events occured 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. |
