RESTING MARINE ROTIFER CULTURES (Brachionus plicatilis) 3-5000 Cysts
Rotifers, like Artemia, produce resting eggs or cysts. Yet, rotifers are uniquely different since they reproduce asexually (without sex) and only one rotifer becomes millions in a matter of days. Florida Aqua Farms pioneered this process and offer vials of lab cultured rotifer cysts. Cysts stored in a freezer can last over two years. Remove cysts from the vial, place in 1/2″ of water, cover, place in continuous low light. Hatching and feeding commences within 24 to 36 hours and reproduction about 18 hours after hatch. Resting eggs of the saltwater rotifer Brachionus plicatilis. We offer only the “L” strain which are 130-340 µm long compared to new hatched Artemia which are 450-500 µm long. Smaller strains can be cultured by consistently sieving normal cultures for smaller individuals and culturing them. To determine what size inoculant would best suit your needs we offer a theoretical calculation of inoculant size and the approximate days for a population to reach 1 billion. Results vary depending on water quality, food and temperature.

Rotifers are small (50-1000 µm) zooplankton that occur in freshwater, brackish, and marine environments. Rotifers feed on microalgae and are consumed by a wide variety of fish, shellfish, corals, and other organisms. They are used extensively in aquaculture and aquariums because of their very high reproductive rates (as great as doubling or better every 24 hours), ease of culturing, optimal size for larval fish, and nutritional profile that can be tailored to the needs of prey species by use of special feeds such as Reed Mariculture’s RotiGrow® ranges.

Florida Aqua Farms Inc. (FAF) founded in October 1984, is basically considered a manufacturing entity. We are unique among aquaculture suppliers since the original founders, Frank Hoff, William Hoff and Terry Snell have been directly involved in aquatic research, applied aquaculture and the aquarium industry since 1966. Coupled with our past expertise is our continued involvement in research and consulting within the aquaculture community. Current and past endeavors include; new product development, culturing micro and macroalgae, zooplankton culture, spawning and rearing freshwater discus and angelfish, saltwater clownfish, pompano, seabass and numerous other aquatic animals. Florida Aqua Farms Inc. continuously researches, formulates, updates and manufactures products found in this catalogue. Of considerable importance to you is the fact that the owners of Florida Aqua Farms use or have used most products found in this catalogue in their current or previous facilities. Using our product line allows us to make modifications and changes that benefit our customers.Our expertise is concentrated in the controlled conditioning, spawning, larval rearing and early juvenile growout of fish and invertebrates in closed recirculating systems. Our product line is purposely concentrated into our specialized fields of expertise. A significant portion of our product line leans towards intensive, closed culture of live foods including microalgae, rotifers, Artemia and daphnia. Many products are best suited for indoor, closed system, hatcheries, wet-labs, pilot scale projects or experimental work. Most of our products are traditionally found in scientific research labs and educational facilities but, are often difficult for aquatic farmers to locate or obtain. Other products are more common in the aquarium industry but are not usually found in aquaculture. This unique blend of products makes Florida Aqua Farms Inc. USA a special entity rather then just another “me-too” manufacturer and supplier.
