The effect of water salinity (3, 10, 20, 30, 40, 50 and 60‰) on growth and proximate as well as mineral composition of Pacific whiteleg shrimp Penaeus vannamei was evaluated in a 45-day indoor trial. Significantly higher (p<0.05) growth was observed between 10 and 30‰ salinity, with specific growth rate and daily growth coefficient of 2.57-2.64 and 2.00-2.08 respectively. Poor survival of 26.66% was noticed at 60‰. Higher levels of protein and lipid as well as lower levels of moisture and ash were found in shrimp reared in high salinity water. Calcium level in whole shrimp was around 30 g kg-1 up to 30‰ and a gradual reduction was observed from 40 to 60‰ (23.49 to16.24 g kg-1). Sodium and potassium contents were significantly (p<0.05) higher and lower respectively in hyper saline reared shrimp carcass. Ca: P ratio was almost constant at 3:1 in shrimps reared up to 30‰ salinity and the ratio decreased beyond 30‰. The mineral profiles of water and shrimp were negatively correlated for calcium (-0.830), potassium (-708) and Ca: P ratio (-0.654). The present results indicate that potassium and magnesium supplementation may be helpful in low saline waters and limiting the mineral quantities in the diet especially calcium, magnesium, sodium and potassium may be advised for high salinity shrimp rearing.

Artemia sp. is a common natural feed for shrimps at the post-larvae stage and is characterized by poor lipid content. Therefore, Artemia is commonly enriched with specific nutrition, including biofloc. This contains some useful nutrients in the form of protein and polyhydroxy butyrate (PHB). The aim of this study was to analyze the effect of Artemia enriched with biofloc on the growth performance of black tiger shrimp, P. Monodon, and whiteleg shrimp P. vannamei. This research used acompletely randomized design (CRD), encompassing three treatments of feed and four replications. The tested treatments include: (a) Artemia sp. without enriched (b) Artemia enriched with biofloc, and (c) biofloc without Artemia, and the treatments were fed on black tiger as well as whiteleg shrimp post-larvae for 15 days. The results showed the significant effect of using  Artemia sp. enriched with biofloc on the growth of P. monodon and P. vannamei, but not on the survival rate. However, both parameters were significantly influenced for post-larvae shrimp at a dose of 30 mL biofloc. This served as a nutritional source by providing the best growth of 14.57 mg and 15 mg at a daily growth and survival rate of 0.86 mg day-1: 98% and 1.4 mg day-1: 99% for P. vannamei and P. monodon, respectively.
