Brine Shrimp Cysts


SKU: N/A Category:


Florida Aqua Farms offers one and three ounce bottles of high quality Artemia cysts. These are Great Salt Lake Utah cysts, grade A (85% percent hatch). Our cysts are processed by INVE, the oldest, most respected, company in this field. Cyst moisture content is 6 to 7%, with 225,000 to 250,000 cysts/gram. Volume of hatched nauplii per 5 grams of cysts within 24 hours hatch is 50 cc’s at 27° C. Nauplii per gram of cysts is 220,000 to 230,000. Average size of nauplii at 24 hours is 458 microns. Fatty acid profile is excellent but can be enhanced by feeding live microalgae about 12 hours after hatching. Keep in mind how fast they are utilized once the bottle is opened. Moist, hot, climates, like those found in hatcheries cause eggs to deteriorate quickly. Proper storage of cysts is an important consideration. Shelf life of opened or unopened cans is extended if stored at cold temperatures (below 50°F or 10°C) preferably in a refrigerator or freezer. Optimal hatching conditions are; Temperature 25-30°C (77-86°F), pH of 7.5 to 8.5, lighting for 24 hours at 2000 lux and salinity of 25 to 25 ppt (1.0183 to 1.0260). Hatch is usually at 24 to 36 hours. Unhatched eggs sink to the bottom and can be restarted. Hatched eggs float to the surface and nauplii are situated in the water column. To obtain optimal hatch see our hatchers and our Plankton Culture Manual.
