Biofloc Production Systems for Aquaculture
Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...
متن کاملRelative contribution of natural productivity and compound feed to tissue growth in blue shrimp (Litopenaeus stylirostris) reared in biofloc: Assessment by C and N stable isotope ratios and effect on key digestive enzymes
The aim of this study was to assess the relative contribution of natural productivity and compound food to the growth of the juvenile blue shrimp Litopenaeus stylirostris reared in a biofloc system. Two experiments were carried out based on the same protocol with three treatments: clear water with experimental diet (CW), biofloc with experimental diet (BF) and biofloc unfed (BU). Shrimp surviva...
متن کاملApplication of Bacillus amyloliquefaciens as probiotic for Litopenaeus vannamei (Boone, 1931) cultivated in a biofloc system
Probiotics can improve growth, survival and resistance to pathogenic organisms of the cultivated species in aquaculture systems with water recirculation. However, their possible benefits on biofloc systems have been less studied. In this study, the benefits of Bacillus amyloliquefaciens bacterium, on a biofloc culture of Litopenaeus vannamei were evaluated. B. amyloliquefaciens was applied as d...
متن کاملEvaluation of Pacific White Shrimp (Litopenaeus vannamei) Health during a Superintensive Aquaculture Growout Using NMR-Based Metabolomics
Success of the shrimp aquaculture industry requires technological advances that increase production and environmental sustainability. Indoor, superintensive, aquaculture systems are being developed that permit year-round production of farmed shrimp at high densities. These systems are intended to overcome problems of disease susceptibility and of water quality issues from waste products, by ope...
متن کاملThe effect of different carbon sources (molasses and spoilage date palm fruit juice) on water quality, growth performance and body composition of Pacific white shrimp (Litopenaeus vannamei) culture in biofloc system
In the current study, the effect of spoilage date palm (Phoenix dactylifera L.) fruit juice and molasses on Pacific white shrimp (Litopenaeus vannamei) cultured in a biofloc technology (BFT) surveyed. Four bioflocs were managed: BFT fed diets of 25% CP and palm juice (P25), diets of 25% CP and Molasses (M25), diets of 15% CP and palm juice (P15), diets of 15% CP and Molasses (M15) and clear wat...
