Spirulina
A cyanobacteria rich in protein and nutrients, often used as a supplement in aquafeed.
Chlorella
A green microalgae used in biotechnology for its ability to bio-accumulate heavy metals and as a superfood.
Dunaliella salina
Microalgae that accumulates large amounts of beta-carotene, used as a natural colorant and antioxidant in aquaculture feeds.
Haematococcus pluvialis
Freshwater algae known for producing astaxanthin, a compound used in fish feed to enhance coloration, especially in salmonids.
Nori (Porphyra species)
Red algae commonly cultivated for human consumption, also incorporated into feeds for various aquaculture species.
Nannochloropsis
A genus of microalgae high in EPA, a fatty acid valuable for fish nutrition and commonly used in larval rearing stages.
Tetraselmis
A green flagellate algae used as live feed in hatcheries, especially for bivalve mollusks, due to its nutritional profile.
Phaeodactylum tricornutum
A diatom valuable for its high EPA content and use in feeds for bivalves and crustaceans.
Isochrysis
A golden-brown microalgae important in mariculture, especially in the hatchery stage of bivalves, due to its DHA content.
Ulva (Sea Lettuce)
Green macroalgae often used as a biofilter in integrated multi-trophic aquaculture systems, absorbing excess nutrients from water.
Kelp (Laminaria species)
Large brown marine algae used as a feed additive, biofuel source, and bioremediator in aquaculture systems.
Gracilaria
Red algae cultured for the extraction of agar, a gelling agent, and occasionally used directly in herbivorous fish diets.
Schizochytrium
A genus of marine microalgae cultivated for its high DHA content, used in feed formulations to enhance the omega-3 fatty acid content.
Pavlova
A small golden algae used as live feed for a variety of aquaculture species due to its balanced nutritional profile.
Euchema
A type of red algae farmed for carrageenan, a substance used as a thickening agent in food and in aquaculture feeds.
Caulerpa
A green macroalgae noted for its invasive potential, but also utilized as a natural food source for fish and a decorative element in aquaria.
Porphyridium
Unicellular red algae used for producing polysaccharides and pigments, with potential applications in aquaculture as a feed additive.
Artemia
Not an algae, but a brine shrimp commonly used in conjunction with algae in aquaculture as a primary feed for larval stages.
Cyanobacteria
Photosynthetic bacteria that can be both useful and harmful in aquaculture, used selectively in some systems for nitrogen fixation and biomass production.
Chaetoceros
A genus of diatoms frequently used in aquaculture as feed, particularly for larval stages of mollusks and crustaceans due to their size and nutritional value.
