Arthropoda antennata crustacea branchiop (Artemia Salina)

Artemia Salina is a small crustacean living in savory lakes, lagoons, saltworks such as Guérande in Southern Brittany. The biomass he occupies can reach 4G per m3. Its food conversion rate / weight increase is between 76% and 80%. The sexual majority is normally reached in 10 to 20 days in the wild. Under special laboratory breeding conditions in a biotope identical to the composition of the very old seas (the artemia was represented during the oligocene of the tertiary era) and by making it bathe in saturated water of phytoplankton (chlamydomonas Giving green water as dark as ink) of a temperature of 28 to 31 ° C with more addition of certain vitamins and also certain organic matter of benthic algae, sexual maturity can be obtained in only 5 days . Intense lighting must be permanent so that the environment is properly oxygenated by the photosynthesis of phytoplankton. The affected size is then 10 to 12 mm. Under these optimized conditions, the productivity obtained is around 500g of fresh weight / 1000l / day. For a 15 cm high basin culture, productivity remains the same per m2 provided that the medium maintains itself saturated with phytoplankton with high protein content (60%).

Reproduction: it is enough to place several adults, males and female in the same bin with normal (or a little lower) salinity to see couplings. If the salinity is not too large, the little ones are all born. If it is higher, eggs are laid. The surrounding room temperature is enough for reproduction. Be careful, you have to feed the little ones with a food that is suitable for them (different from that of adults: smaller) otherwise they have many dead. Young people are called "Nauplies".
