Expert Forum #3

Lobster and fish larvae are most commonly buoyant and distributed by tidal currents, waves, and other water movements to allow for their dispersal. Similarly zooplankton that spend their lives in the pelagic zone (holoplankton) are at the mercy of water movement. Tidal turbines sited in the estuaries and coastal waters to generate renewable energy are likely to intersect the movement of larvae and zooplankton. Concerns have been raised that commercially and recreationally important species, as well as those that form the base of the marine food web, could be harmed by the operation of tidal turbines.
This forum focused on whether lobster and fish larvae and other zooplankton may be at risk from tidal energy development, whether there is a suitable way to evaluate that risk, and how that risk may be communicated to regulators and stakeholders. (Annex IV Introductory slides). The experts concluded that tidal turbines would be unlikely to pose a risk to these small size classes of marine life.
