BRINE SHRIMP EGGS as live Larval Died

Artemia salinaBrine Shrimp Eggs are the dormancy-eggs (cysts) of Artemia salina, it is a kind of miniature shrimp (crustacea) which distribute widely and bear high sale. At present more than 500 Artemia producing areas in the world are known (such as America, China, Iran and Russia). It's cysts may be conserved very long, and can be hatched as they are needed. The naupii hatch after 18-30 hours in warm (24-30 degree C) salt water (1.5-3.5 % salt), and possess abundant protein and fat. Its grown-body hold high nourishment, so Artemia is an excellent food for various fish and crustaceans. Nutrition Analysis: Protein min. 45 %, Fat min. 15 %, Ash min. 6 %, Fiber max. 2 %, Moisture mx. 8 %. They are available as "World Premium Quality" in 425 gram (15 oz) cans (Net Weight), and 12 cans per case.

Artemia is generally used for feeding the late larval and postlarval stages of shrimps. Freshly-hatched nauplii are usually offered beginning with the first mysis stage, and sometimes earlier at the zoea-mysis molt. It is the most successful diet throughout the larval rearing period of freshwater prawn larvae. In contrast to penaeid shrimp, Macrobrachium can initially be fed with freshly-hatched Artemia nauplii, at densities higher than 100 nauplii per liter to assure proper ingestion.
The larvae of several species of marine fish, e.g., bass, bream, grouper, and turbot, can only be offered an Artemia diet after an initial period on a smaller prey, primarily the rotifer, Brachionus plicatilis. In contrast to crustacean larvae, marine fish larvae are cultured on Artemia for a much longer period of time (e.g., 20 to 40 days). Artemia cyst consumption is also among the highest in marine fish larviculture and ranges from 200 to 500 g per 1000 fry produced.
Freshwater fish larviculture is often carried out in ponds with natural zooplankton as the larval food. Nevertheless, several species of freshwater fish are fed Artemia. Therefore, a 10-20 days feeding period on brine shrimp for freshwater fish larvae prior to the feeding of traditional artificial diets is recommended. Both live and frozen adult Artemia are used as food for aquarium fish species. Cysts are also purchased by these users and hatched for feeding as nauplii. Survival, vigor and pigmentation were reported to be significantly improved in several tropical species.

DECAPSULATED BRINE SHRIMP EGGS

Decapsulation consist of chemically removing the shell or chorion of the Artemia cysts and leaving only the embryo. We remove the shell with short exposures to a hypochlorite solution, neutralize the reaction and rinse thoroughly. Decapsulated brine shrimp offer, compared to the non-decapsulated ones, the advantages that the cyst shells are not introduced to the culture unit, they have a higher energy content because they use no energy to hatch-out of their shell,  because of the decapsulation process (hypochorite solution) the product becomes thoroughly disinfected, they are an ready-to-use energy-rich food source and have a smaller particle size which is more suitable for smaller larvae.

We deliver also frozen zooplankton as natural fry feed for all fish species!

EXTRUDED ENERGY FEED for Fish

This specially formulated and extruded dry feed with a reddish-brown colour has a well balanced fatty acid profile and promotes good appetite, fast growth, high survival and fish health. The extruded feeds are based on raw material of superior quality and are formulated as a starter and grower feed specially in closed water or recirculation systems, with minimal phospate content and low nitrogen excretion. The particle sizes are also very stable in the water and hardly pollute it. The feed is highly energetic which guarantee very low feed conversion rates. It can be used from the first day on or as a replacement feed of brine shrimp and zooplankton "artificial plankton". It is suitable for the production of various fish species such as Salmonids, Percids, Acipenserids, Cyprinids and other species too. It is available in 10 or 25 kg bags, at the following types and sizes.
