Abstract A bloom of the green microalga
Tetraselmis
sp. in a small lagoon in Wellington Harbour, New Zealand, is considered to have
caused a fish kill of pilchards (
Sardinops sagax). The fish deaths are
attributed to anoxia brought about by a combination of reduced dissolved oxygen
levels and the microalgae sticking to and clogging the secondary gill lamellae
of the fish.
