Tisochrysis lutea Phytoplankton Culture

Product Overview

Tisochrysis lutea is the taxonomically correct name for the legendary T-ISO strain—the golden DHA powerhouse trusted by marine hatcheries and elite reef aquarists worldwide. These 4-6 micron golden-brown flagellates deliver the highest DHA omega-3 content of any phytoplankton species, providing the specific long-chain fatty acid essential for coral tissue growth, larval neural development, and clam shell formation. Soft cell walls ensure rapid digestion and immediate nutrient bioavailability that hard-walled species cannot match.

Perfect for growth-focused reef systems and larval rearing operations, Tisochrysis lutea represents decades of aquaculture research identifying the single best phytoplankton for marine organism development. The golden pigmentation from fucoxanthin carotenoids enhances yellow and orange coloration in corals while supporting zooxanthellae photosynthetic efficiency. Beyond direct coral feeding, Tisochrysis creates premium DHA-enriched copepods when used for gut-loading—the fatty acids concentrate in copepod tissues and transfer to fish through predation. Recent taxonomic work separated Tisochrysis from Isochrysis genus, but the exceptional nutritional properties of the T-ISO strain remain identical. Active flagellar swimming maintains extended water column suspension for efficient consumption. Tisochrysis lutea arrives as a living, actively dividing culture ready to drive growth and coloration immediately upon addition.
