Abstract


Effect of concentrations of living food Artemia salina on survival and growth performances of marine shrimp Farfantepenaeus notialis (Pérez Farfante, 1967) from the Zoe 3 to Post larvae 1 stages, was carried out at AquaSol (Aquaculture Solidarité) structure in IRAD (Institute of Agricultural research for Development) of Kribi in Cameroon between July and August 2013. 3600 larvae (Zoe 3) born from a pregnant female (with total weight 70.6 g and 20 cm total length), collected in the natural environment by a fisherman using a bottom thread were used. The larvae were bred in an experimental device consisting of 6 treatments seeded in 3 replicates each. Treatments were randomly distributed into 18 cylinder-conical plastic bottles. Larvae were fed at different levels of concentration of imported Artemia salina nauplii (AN) (0 AN/ml, 1 AN/ml, 2 AN/ml, 3 AN/ml, 4 AN/ml and 5 NA/ml), Microalgae Thalassiossira pseudonana cultivated in the station and with a dry imported food. The best performances of survival, growth and metamorphosis were produced by 3 AN/ml concentrations of Artemia. The cost of food has increased with the concentration level of Artemia. Then, the production of viable shrimp post larvae and cheaper may be done at 3 AN/ml optimal concentrations of Artemia.
