INTRODUCTION:

Artemia is generally used for feeding the late larval and post larval stages of penaeids. Freshly-hatched nauplii are usually offered at the start of the first mysis stage, and sometimes even earlier at the zoea-mysis molt with some authors even recommending the introduction of Artemia during the second zoea stage. However, penaeids are usually fed algae prior to the Artemia and undergo a several-day weaning period when both foods are given. Thus, the addition of Artemia too early in the life cycle may result in the competition for the algal food between the uneaten Artemia and the penaeids. A convenient solution may be the early administration of killed nauplii (short dip in a water bath at 80^°C; or frozen in thin layers at -10°C) or the use of decapsulated Artemia cysts. Enriched Artemia nauplii can also be administered from the postlarval stages onwards.

Artemia nauplii is the most successful diet employed for the larval rearing of freshwater prawn larvae. In contrast to penaeid shrimp, Macrobrachium can initially be fed with freshly-hatched Artemia nauplii, at densities higher than 0.1 nauplii.ml^-1 to ensure proper ingestion. Energy intake in M. rosenbergii was directly proportional not only to Artemia concentration but also to Artemia size the (n-3) HUFA-requirements of Macrobrachium were anticipated not to be very critical in view of the fact that these animals spend most of their life in freshwater.

PRODUCT SPECIFICATIONS:

Tropical Biomarine Systems Pvt Ltd is one of the sub-leased harvester of artemia from Great Salt Lake of Utah, USA. Our artemia is processed with strict quality control measures. We use only premium grade, quality analyzed, brine shrimp eggs from the Great Salt Lake in Tropical select cans. Packaged in lithographed, high vacuum cans.

100% Great Salt Lake Brine Shrimp eggs (Artemia cysts) processed by state of the art fluid bed dryers. High quality, guaranteed to hatch at 90% plus, with excellent separation of nauplii from un-hatched cysts. Packaged in 15 once (425 gram) or 16 once (454 gram) high vacuum cans.

Hatching Efficiency:

Nauplii per gram hatched under optimum conditions (2 grams of cysts per liter, 28 C over 24 hours).

Cyst Storage:

· Artemia cysts are best stored at low humidity,

· low temperature conditions to maintain their hatching quality.

· For long-term storage, store at temperatures below 10 C but above freezing.
