Fresh frozen Cyclops is the perfect tiny food item for filter-feeding invertebrates, soft corals, hard corals, and juvenile or small marine fish. They are larger than the tiny Rotifers mentioned above.  They are about the same size as baby brine shrimp, but they are a nutritionally superior replacement for baby brine shrimp as aquaculture food items.

In aquariums, Cyclops is used as food for small fish – half-inch long up to 2 or 3 inches.  They are also in a size range which is very suitable for SPS (small polyp stony) Corals like Acropora and for LPS (Large Polyp Stony) corals which have larger polyps and can be rather aggressive as carnivores.  Cyclops is not likely to be used as food for inverts such as sponges, tunicates, and bi-valves which filter-feed on phytoplankton and other very tiny organisms.

Cyclops is the actual Latin name of the genus which is comprised of hundreds of different species. Cyclops sp. is COPEPODS and, as such, they are related to many other types of “PODS.”  The various species of Cyclops are very common throughout the world in freshwater, brackish and marine environments.  The name Cyclops refers to their appearance of having one large eye, often either red or black.

In the vast regions of pond aquaculture in northern coastal China, Cyclops sp.function in a very similar manner to that of Rotifers.  Like Rotifers, they are produced in very large numbers during the cycling of the fish or shrimp grow-out ponds where they feed on the algae blooms that occur after the ponds are harvested, drained, re-filled and fertilized.   The Cyclops are normally harvested while “gut loaded” with very nutritious phytoplankton. If they are rushed to the packaging factory, they can be frozen with the fresh nutrition of the phytoplankton still intact and not fully digested.

Cyclops sp.vary in color from brown to orange or reddish orange, depending on the season and the color of the phytoplankton on which they are feeding.  They do not have the extremely red color of the arctic copepods, the so-called Cyclopeeze, but they are basically very similar in terms of their nutritional value to small fish and corals.

The statement made above-concerning Rotifers, can also be made in the case of Cyclops.  Northern coastal China is one of the few areas in the World where Cyclops can be grown in such large numbers as to be suitable to harvest, drain, rinse and package into small cube trays or plastic bags and then FROZEN for future use.  The vast quantities of the individual animals needed to produce enough volume to fill a single one-kilogram package are mind-boggling. The sheer volume required to supply the relatively small aquarium industry un-fathomable.  As aquarists, we are very fortunate to have this product….which is basically no more than a natural by-product of the farming of fish and shrimp in ponds which are grown to provide food for humans throughout the world.
