Inbound invasives

Like strange fruit, ascidians cling to a wharf pile in Te Hapua. A native of Australia, they first appeared in Houhora Harbour in 2005 and were later found on oyster racks here in Parengarenga, likely brought in on the hull of an oyster barge.

The ascidians displace native marine flora, but don’t seem to concern the glass shrimp, which dance around the domes of the camera.

Invasive species can be spread by boats moving around the coasts, particularly between harbours. Check out MPI’s list of invasive marine organisms and keep hulls clean and checked.
