The tropical fish Notropis atherimoldes (0.2–0.4 g) was found to be highly sensitive to saxitoxin (STX) and well‐suited for use in the biological estimation of saxitoxin. STX in distilled water at a concentration of 3.3 ng/mL resulted in a paralytic end‐point being reached in 17.5 min. The assay is ideally suited for initially detecting the presence of paralytic shellfish toxins in bacterial culture supernates.
