The controlled production of aquatic organisms.
Arachidonic Acid ((18:2n-6) - expressed as a % of Lipid, an omega-3 long chain polyunsaturated fatty acid.
Aids in the expulsion of harmful ammonia from the body.
An arthropod that is commercially harvested as a feed product for the aquaculture industry. It is found world wide in hyper saline bodies of water such as the Great Salt Lake in Utah and the San Francisco Bay. For more information see Brine Shrimp Direct's web page.
Microscopic animals ranging from 50 to 2000 microns that are used to feed larval fish and shrimp, and corals. For more information click here.
Instant Algae's® brand of semi-frozen marine microalgae concentrate. In 2001 CryoPaste was replaced with the Premium formula that does not contain any preservatives. CryoPaste can still be made on request.
Cryoprotection is the process of freezing a substance without damaging it. In the case of microalgae the objective is to prevent damage to the cell from ice crystals. It also preserves the nutritional value of the cells by slowing their metabolic rate to a suspended state. This prevents bacteria from growing and contaminating the concentrate.
Docosahexaenoic Acid (C22:6n3), an omega-3 long chain polyunsaturated fatty acid. DHA is one of the building blocks of neural tissue. It is very important in the development and growth of larval fish, shrimp, and shellfish. It is commonly used for enriching rotifers. Two of our algae (T-ISO and Pavlova) are very high in DHA. Please see our Proximate Analysis page for more information about DHA levels in Instant Algae® microalgae.
Eicosapentaenoic Acid C20:5n3, an omega -3 long chain polyunsaturated fatty acid. EPA is one of the building blocks of neural tissue. It is very important in the nervous system growth of larval fish, shrimp, and shellfish. It is commonly used for enriching rotifers. Two of our algae (Nannochloropsis and Tetraselmis) are very high in EPA. Please see our Proximate Analysis page for more information about EPA levels in Instant Algae®.
A technique of adding microalgae to your system as an enhancement, not as a direct food source. For more information please see our Greenwater web page.
Highly unsaturated fatty acids. HUFA's are important in the metabolism and growth of marine organisms, both fish and crustaceans.
Marine aquaculture.
Single celled plants that are the bottom of the marine food chain. Microalgae absorb nutrients such as ammonia, urea, nitrates, phosphates, and potassium, vitamins and metals.

These consist primary of EPA, DHA, and ARA. These fatty acids are critical to the development of the brain and neural system in larval animals. These are also the "heart healthy" fatty acids common in salmon, tuna, and other marine fish. Some Omega-3 fatty acids can also improve pigmentation (color) in marine organisms.
Plankton refers to "drifting" or "passively swimming" organisms and is a broad category for microscopic plants and animals that drift with the ocean waves. In the marine life cycle food chain plankton is at the bottom and therefore the key ingredient in growing any other animals further up the chain. For this reason plankton is a critical component in marine hatcheries, aquariums, and scientific research world-wide.
"Plant" plankton - Microalgae and Macroalgae
"Animal" Plankton - Brine shrimp (Artemia), rotifers, copepods, daphnia, etc.
Zooplankton are microscopic or somewhat larger grazing aquatic animals. Many zooplankton feed on microalgae and form the second major link in the food web. Plankton Culture Manual, Frank Hoff and Terry Snell
Live microbial feed supplements that improve health of man and terrestrial livestock.
Microscopic animals ranging from 50 to 300 microns that are used to feed larval fish and shrimp, and corals. For more information click here.
Serine is a nonessential amino acid that is essential for the metabolism of fats as well as fatty acids.
Baby shrimp go through many changes or "molts" in their first few days. There are three larval phases (nauplii, zoea, and mysis) that take followed by a post larval period (PL) phase. For more information please see our Shrimp web page.
Nauplii (Hatch --> day 2) - N1 to N5
During the nauplii phase the shrimp eat from their egg sack.
Zoea (Day 2 --> day 4) - Z1, Z2, Z3
During the Zoea phase the shrimp start eating microalgae. During this time they are high energy swimmers that filter feed on microalgae.
Mysis (Day 5 --> day 10) - M1, M2, M3
During the mysis phase the larvae continue to grow rapidly and will drift upside down. They become omnivorous, eating both microalgae and zooplankton (usually brine shrimp nauplii/Artemia)
Post Larval Shrimp (Day 11 --> day 21) PL1 to PL10
In the PL phase the shrimp start swimming right side up and become benthic (living at the bottom or on the sides). At the end of the PL phase the shrimp are ready to be moved into grow-out ponds.
This is a poorly defined problem that causes high mortality rates with zoea phase shrimp. The symptom of the problem is that the shrimp never start eating. There is currently a great deal of research being done to understand the cause and cure.
