This review deals with the measurement of filtration rates in suspension feeding bivalves, and some reliable filTration rate data obtained under optimal laboratory conditions are presented.
Filtration rate capacities in 6 species of European freshwater bivalves
The measured filtration rates in undisturbed bivalves are substantially higher (at least 4 times) than previously reported, indicating that the impact of bivalve water processing on freshwater ecosystems is greater than hitherto suggested.
SUSPENSION-FEEDING IN MARINE SPONGES HALICHONDRIA-PANICEA AND HALICLONA-URCEOLUS - EFFECTS OF TEMPERATURE ON FILTRATION-RATE AND ENERGY-COST OF PUMPING
: Filtration rate (measured as clearance of algal cells) was measured at different tempera- tures in the sponge Halichondna panicea. An increase in water temperature from 6 to 12 "C caused the mean…
Regulation of opening state and filtration rate in filter-feeding bivalves (Cardium edule, Mytilus edulis, Mya arenaria) in response to low algal concentration
Growth, filtration and respiration in the mussel Mytilus edulis:no evidence for physiological regulation of the filter-pump to nutritional needs
The results show that there is no physiological regulation of the filtration rate to nutritional needs, and that food uptake in nature is characterized by the full exploitation of the capacity of the bivalve filter-pump.
Growth and energetics of the sponge Halichondria panicea
It was found that sponges apparently have a higher energy demand for growth than other invertebrates, but compensate for this by a high retention efficiency for small particles z0.1 pm.
Filtration capacity of the ascidian Ciona intestinalis and its grazing impact in a shallow fjord
The results suggest that the population of C, intestinalis in Kertinge Nor may have an important grazing impact on the phytoplankton in late summer-early fall.
In situ feeding rates of plantonic copepods: A comparison of four methods
Particle capture mechanisms in suspension-feeding invertebrates
The current physical and biological understanding of the capture process is discussed and a number of specific problems related to particle capture are suggested, which may be solved in the future using advanced theoretical, computational and experimental techniques.
Tentacle structure and filter-feeding in Crisia eburnea and other cyclostomatous bryozoans, with a review of upstream-collecting mechanisms
The differences in structure and functlon between the tentacles of ectoprocts and those of phoronids, brachiopods and pterobranchs support the idea that the 2 types of tentacle crowns are not homologous.
