Filtration rates of the invasive pest bivalve Limnoperna fortunei as a function of Size and Temperature
Clearance rates of Limnoperna fortunei (Bivalvia) were investigated in laboratory experiments using monocultures of the alga Chlorella vulgaris. Experimental conditions included two mollusc sizes (15 and 23 mm), and three water temperatures (15, 20 and 25°C) covering the normal seasonal range in the...
