Group sweeping: Feeding activity and filtration rate in the tubiculous amphipod Haploops nirae (Kaim-Malka, 1976) ArchiMer
Rigolet, Carinne; Le Souchu, Pierrick; Caisey, Xavier; Dubois, Stanislas.
Haploops nirae is a gregarious tubiculous amphipod that uses its two pairs of antennae to filter particles from the water column. Recent sonar mappings of Haploops seabeds revealed that thousands of hectares of softbottom muddy sediments in South Brittany coastal ecosystems are now colonized by this amphipod. The present study investigates (1) the structure of the feeding organs and the mechanisms involved in particle capture, (2) the effect of environmental parameters (current velocity, turbidity and food concentration) on the feeding activity of H. nirae, quantified by the percentage of active individuals, the frequency of antennae beats and the number and duration of feeding events and (3) the retention efficiency and clearance rate of H. nirae...
