- Abstract
We tested the hypothesis that yield of the musselPerna canaliculus(Gmelin 1791) could be increased by placing culture ropes deep into the water column to take advantage of deep-water chlorophyllamaxima. The study site, in Pelorus Sound, New Zealand, showed periods of thermal stratification of the water column, causing a high concentration of phytoplankton in deeper water, at the thermocline. Mussels were grown simultaneously at 5 and 17 m, for up to 96 days. Mussel growth and condition index data showed no significant differences between the two depth treatments, indicating that in this system there may not be substantial mussel productivity benefits from lowering mussel farms to the deep-water chlorophyll maximum layer.
