Abstract
Vulcanodinium rugosum., the scrippsielloid dinoflagellate producer of pinnatoxins, was
isolated from surface sediments collected from Northland, New Zealand, in summer
2008/2009. The dinoflagellate was isolated and cultured predominantly in cyst form, with the
New Zealand isolates producing pinnatoxins E and F and Australian isolates predominantly G
and less E and F. V. rugosum killed sea urchin and paua larvae and caused morbitity in sea
slug larvae; Pacific oyster and Artemia salina larvae became slightly moribund. GreenshellTM
mussel larvae were unaffected. Depuration rates of 50% of pinnatoxin E and F from Pacific
oysters were 14.5 and 16 d respectively. Crude extracts of mass cultures of the New Zealand
and Australian isolates tested for toxicity in mice by intraperitoneal injection, gavage and
voluntary consumption resulted in toxicity ratios of 1.0: 1.8: 4.5 and 1.0: 2.9: 7.8 respectively.
