The suspension feeding of Bithynia tentaculata was tested in laboratory experiments. The animals were fed in 1-1 aerated glass beakers, and filtration rates were calculated from changes in cell concentrations during the 6-h experiment. Temperature influenced the filtering rate, with minimum values of 5ml · ind-1 · h-1 at 5° C and maxima of 17.2 ml ...

The two freshwater gastropods Radix peregra and Bithynia tentaculata were fed with unlimited quantities of diatoms, green algae, cyanobacteria, maple leaf detritus and natural sediment for 11 weeks. Shell growth rates ranged from 0.0 mm per week with sediment and maple leaf detritus as food to 0.29 mm per week (B.

Age- and sex-specific grazing rates have been studied in specimens of Bithynia tentaculata from Oneida Lake, New York. Two artificial foods and Aufwuchs grown in Oneida Lake were used as grazing substrates. These foods were of different protein quality and organic content. Concomitant analyses of assimilation, respiration and nitrogen excretion allowed

Identification of an estrogen receptor gene in the natural freshwater snail Bithynia tentaculata
Gene, 2014Mollusks have received increasing interest in ecotoxicological studies but so far the available scientific analyses of how their genes are affected by anthropogenic pollutants are scarce. The focus of this study is to identify an estrogen receptor (er) gene in the common prosobranch snail Bithynia tentaculata and to test a hypothesis that 17α ...

Development, 1974
ABSTRACTIn the first polar lobe of the egg of Bithynia tentaculata a cup-shaped mass of small vesicles is described, which fills the greater part of the lobe. It is named the ‘vegetal body’. With methyl green-pyronin the vegetal body stains clearly, but after treatment with RNase no staining occurs, thus indicating the presence of RNA.

The present investigation on the biology of Bithynia tentaculata has two aims. Firstly to report on the life cycle, growth, reproduction and other aspects of the biology of this snail, and secondly to identify the larval trematode infection of the snail and to report on the incidence, seasonal variation and the development of these infections.

The non-native faucet snail (Bithynia tentaculata) makes the leap to Lake Superior
Journal of Great Lakes Research, 2015Abstract The European-origin faucet snail ( Bithynia tentaculata ) has been present in the lower Laurentian Great Lakes since the late 1800s but only very recently reached Lake Superior. Surveys from 2011 through 2013 found faucet snails abundant and wide-spread in the St.
