In bivalves, water-pumping potential is determined both by ciliary activity and by the geometry of the system of passageways that acts as a conduit for water flow. Smooth muscles intrinsic to the gills of eulamellibranch bivalves possess the anatomical organization needed to regulate the dimensions of these water passageways. The tone of these muscles can be controlled experimentally using excitatory neurotransmitters to elicit muscle contraction and by removing Ca++ from the Ringer’s solution… 

Sodium Gill Potential as a Tool to Monitor Valve Closure Behavior in Freshwater Clam Corbicula fluminea in Response to Copper

An electrophysiological response model of C. fluminea is derived to assess copper (Cu)–sodium (Na) interactions in gill membrane, whereby valve closure behavior and Cu toxicity could be monitored to monitor waterborne metal toxicity.

Branchial Musculature of a Venerid Clam: Pharmacology, Distribution, and Innervation

It is proposed that 5HT is the excitatory transmitter to the gill muscles, and that DA and ACh exert their excitatories effects by stimulating 5HT motor nerves.

In vivoEffects of Brown Tide on the Feeding Function of the Gill of the Northern Quahog Mercenaria mercenaria(Bivalvia: Veneridae)

In vivo response of adult northern quahogs, Mercenaria mercenaria, to Aureococcus anophagefferens (brown tide) at the level of the gill was determined using video-endoscopy and could be caused by either a dopaminergic or a serotonergic toxic factor.

Synchronization of Reproduction in Deertoe Mussel (Truncilla truncata)

Sperm activated and detached from spermatozeugmata in the presence of unfertilized eggs, suggesting that a chemical signal released by the eggs triggers sperm to disassociate from spermae, however, contact with female gills did not trigger dissociation.

Seasonal control of particle clearance by isolated gills from the clam Mercenaria mercenaria

Clearance rates of isolated gills behave in a manner consistent with the seasonality and pharmacology of the lateral cilia and branchial musculature, and the gills were more sensitive to DA in winter than in summer.



Musculature Associated with the Water Canals in Freshwater Mussels and Response to Monoamines In Vitro.

When gills are exposed to 10-5 M serotonin in vitro, both ostial openings dilate and gill ciliary activity increases, and the net result of serotonin treatment is an increase in ciliaryactivity, a maximal opening of the water canal ostia, and, presumably, an increase of water flow through the gill.

Some mechanisms for the control of pumping activity in bivalves

Water flow in a bivalve has been examined from a theoretical standpoint and suggests that an 80 % reduction in the size of the exhalant aperture is required before greatly affecting the total resistance to flow through the system.

On the Ciliary Mechanisms and Interrelationships of Lamellibranches: PART VIII: Notes on Gill Musculature in the Microciliobranchia

In the gill axes of the Microciliobranchia the most important muscles are longitudinal and transverse, and horizontal muscles of the lamellae, found chiefly in the Pteriacea, are responsible for dorso-ventral contraction of the demibranchs.

The bivalve pump

Removal of the laterofrontal cirri from the flow path drastically decreased the efficiency with which S 6 pm algal particles were retained by the gills, but it had no or little effect on the retention of 14 urn particles, supporting previous lndlcations that the later of prefrontal cirri do not act as sieves of the through current, but rather as modulators in the process of particle retention.


It is concluded that the feeding state of the bivalve gill, which is characterized by high rates of water transport through highly retentive gills, is restricted to undisturbed, intact animals.


The fibrous structural material of the gill and the associated muscle fibers according to their comparative ultrastructure are identified and a detailed understanding of the basic composition of these elements does not exist.

Multipurpose Gills: Effect of Larval Brooding on the Feeding Physiology of Freshwater Unionid Mussels

Video endoscopic techniques were used to describe and compare, in vivo, the feeding structures and dynamics of brooding and non-brooding females, consistent with the hypothesis that observed reductions in particle clearance rates and retention efficiencies in brooding female mussels are the result of functional changes in the ciliature and flow dynamics of the marsupial gills.

Memoirs: The Neuro-Muscular Mechanism of the Gill of Pecten

The subsidiary branchial nerve is a structure hitherto unknown in the molluscan gill; so far its function is unknown.

Gill pump characteristics of the soft clamMya arenaria

Pumping rates in the soft clam Mya arenaria, collected in June 1987 in the Great Belt, Denmark, were determined as rates at which clams cleared suspensions of algae, Dunaliella marina, consistent with the conception that the capacity of filter feeding bivalves to process large amounts of water depends upon a low resistance to water flow in the siphons.
