In April 1995, an unusual large‐scale red tide of Heterosigma akashiwo (Hada) Hada occurred, causing massive fish kills in Kagoshima Bay, Japan. Four neurotoxic components, HaTx‐ i , HaTx‐ ii a, HaTx‐ ii b and HaTx‐ iii , which corresponded to brevetoxin components. PbTx‐2. PbTx‐9, PbTx‐3 and oxidized PbTx‐2, were inferred from analysis of Heterosigma red tide toxins on TLC and HPLC.
