Reproductive Biology of Amblema neislerii, Elliptoideus sloatianus, Lampsilis subangulata, Medionidus penicillatus, and Pleurobema pyriforme (Bivalvia: Unionidae): final report
A study on the reproductive biology of Amblemaneislerii, Elliptoideus sloatianus, Lampsilis subangulata,Medionidus penicillatus, and Pleurobema pyriforme wasconducted from May 1995 to May 1997. The objectives of thisstudy were as follows: 1) determine period of gravidity foreach of the five mussel species, 2) determine host fish vialaboratory experiments, 3) test whether unionid glochidiawill transform on a nonidingenous fish, and 4) describe theglochidial morphology for each of the five mussel speciesusing a scanning electron microscope. Amblema neislerii aretachytictic breeders and were found with mature glochidia inMay. Elliptoideus sloatianus are tachytictic breeders andwere found with mature glochidia from late February to earlyApril. Lampsilis subangulata are bradytictic breeders andwere found with mature glochidia from December to August.Superconglutinates were released by L. subangulata from lateMay to early July. Medionidus penicillatus are bradyticticbreeders and were found with mature glochidia in Novemberand February to April. Pleurobema pyriforme are tachyticticbreeders and were found with mature glochidia from March toJuly. The following fish species served as hosts for A.neislerii: Notropis texanus, Lepomis macrochirus, L.microlophus, Micropterus salmoides, and Percinanigrofasciata. The following fish species served as hostsfor E. sloatianus: Gambusia holbrooki, Poecilia reticulata,and P. nigrofasciata. The following fish species served ashosts for L. subangulata: G. holbrooki, P. reticulata, L.macrochirus, Micropterus punctulatus, and M. salmoides. Thefollowing fish species served as hosts for M. penicillatus:G. holbrooki, P. reticulata, Etheostoma edwini, and P.nigrofasciata. The following fish species served as hostsfor P. pyriforme: Pteronotropis hypselopterus, G.holbrooki, and P. reticulata. Poecilia reticulata, anonindigenous fish, served as a host for E. sloatianus, L.subangulata, M. penicillatus, and P. pyriforme. (76 page document)
