Prymnesium parvum is a species of

red tide, which is an algal bloom
whose toxins lead to harmful effects in people. Although no harmful effects are known, it is recommended not to consume dead or dying fish exposed to a P. parvum bloom.

Prymnesium parvum of Haptophyta is sometimes classified as a

Heterokontophyta
, but the taxonomy of algae is under complex revision, leading to contradictions in terms, especially in non-scholarly texts (such as those from state wildlife departments).

Biology

heterotrophic growth in the dark in the presence of glycerol and grazes on bacteria, especially when phosphate is limited. It has therefore been hypothesized that P. parvum satisfies its phosphate needs by consuming bacteria. P. parvum can use a wide range of nitrogen sources, including ammonium, nitrate, amino acids (which ones apparently depends on pH), creatine, but is unable to use urea
.

New evidence has shown that the toxins produced by this alga are induced by physiological stresses, such as nitrogen and phosphorus depletion due to competition with the environment.
