Production performance and nutritional quality of the fairy shrimp Dendrocephalus brasiliensis Pesta, 1921 (Crustacea, Anostraca) cultured with fish effluent in recirculation system

Larviculture of Brycon amazonicus under Different Food and Farming Systems

“…According to the author, a larva of B. amazonicus, 36 h after hatching, at an average live weight of 1.6 mg, if fed at a rate equivalent to 300% of its live weight would need to consume 537 nauplii/day, since Artemia or D. brasiliensis nauplii weigh 0.01 mg when they hatch. Considering that 1 g of Artemia salina cysts produces on average 240,000 nauplii, it can feed 446 larvae of B. amazonicus, while 1 g of D. brasiliensis, which produces on average 380,000 nauplii [40], can feed more than 700 larvae of B. amazonicus. For a larviculture that produces millions of larvae, it would be more advantageous to use nauplii of D. brasiliensis than Artemia.…”

“…The last four tanks were used for the treatments involving the semi-intensive system of mesocosm (green water), which were managed individually. [40], which may enhance the larviculture of several species of fish used for consumption and those that are ornamental with a high market value.…”

“…Zooplanktonic organisms such as rotifers, cladocerans and copepods greatly benefit from this technique, but during feeding with Artemia nauplii, the maintenance of nutritional quality is guaranteed by the continuous and fractionated distribution in the larvae tanks [37,38]. In a study evaluating the nutritional value of Artemia and Dendrocephalus brasiliensis [39], it was reported that D. brasiliensis (commonly known in Brazil as branconeta) has a nutritional profile superior to that of Artemia salina, in addition to presenting a high productivity of nauplii per gram of cysts [40], which may enhance the larviculture of several species of fish used for consumption and those that are ornamental with a high market value.…”
