Isochrysis is a golden-brown, non-motile microalga prized for its exceptionally high DHA and sterol content; making it ideal for culturing copepods, rotifers, bivalves, and larval fish. Its small cell size and rich nutritional profile support vibrant early-stage marine life and promote long-term system health. Grown under sterile, controlled conditions and shipped live; never stored or preserved; our Isochrysis starter culture is a trusted choice for hatcheries, reef tanks, and aquaculture setups.
Rich in DHA, essential fatty acids, and sterols
Excellent feed for copepods, rotifers, clams, and larval fish
Supports biodiversity and early development stages
Aids in nutrient recycling and water column stability
Shipped live and fresh; no additives; no preservatives
Ideal for dosing or as a base for scaling up your own cultures
