Diseases of Aquatic Organisms, 23(2), pp. 101-108. Comments: Heterosigma carterae (formerly Heterosigma akashiwo) is a flagellated marine phytoplankter which can be toxic to many finfish, including salmonids. |

Comments: Losses of farmed salmon to H. carterea in coastal marine waters of USA from 1986 -1990 have been estimated to be in excess of 11 million dollars. |

Comments: Blooms of the microalga Heterosigma carterae (formerly H. akashiwo) have been implicated in massive fish mortalities at aquaculture sites along the North American Pacific Coast and also in some other regions of the world, particularly Chile, Japan, New Zealand, and Spain. |
