Isochrysis galbana Phytoplankton Culture

Product Overview

Isochrysis galbana is the golden DHA specialist that drives coral tissue growth, clam development, and larval rearing success. These 4-6 micron golden-brown flagellates contain the highest DHA omega-3 levels of any phytoplankton—providing the specific long-chain fatty acid critical for neural development, tissue regeneration, and reproductive success in marine organisms. Soft cryptophyte-like cell walls ensure easy digestion and rapid nutrient absorption that hard-walled species cannot match.

Ideal for aquarists maximizing coral and clam growth or raising larvae, Isochrysis galbana (specifically the T-ISO strain) represents the gold standard in aquaculture hatcheries worldwide. The golden pigmentation from fucoxanthin and other carotenoids enhances yellow-orange coloration in corals while supporting photosynthetic efficiency in zooxanthellae. Beyond direct coral feeding, Isochrysis serves as premium copepod enrichment—copepods fed T-ISO develop higher DHA levels and produce more viable offspring. The medium cell size suits both juvenile and adult filter feeders. Isochrysis galbana arrives as a living, actively dividing culture that begins supporting growth and development immediately upon addition.
