Haslea ostrearia

[/vc_column_text][vc_row_inner][vc_column_inner width=”2/3″][vc_gallery type=”image_grid” images=”3144″ css=””][vc_video link=”https://youtu.be/2DuDPhLZ5rA” css=””][/vc_column_inner][vc_column_inner width=”1/3″][vc_column_text css=””]Morphology

Cells are lanceolate in valvar view, with acute endings. Cell length about 45-50 μm and width about 5-7 μm in the central area. The characteristic water-soluble blue pigments, ‘marenine’, are visible at apices. 

Toxins and toxicity

Not toxic.

Ecology

The blue pigment can cause the greening of oyster gills, ‘’Green Oyster’, in farming ponds. We found this species but sometimes with very weak or without blue pigments.

Distribution and Occurrence

A marine benthic/tychopelagic species (or benthic-periphytic phytoplankton). Common, recorded from the Northern Atlantic coasts (both European and North American), Indian Ocean coast of South Africa, Australia. In this study, it was highly abundant in REF-1 in spring (March-April).
