Immune response and disease resistance of shrimp fed biofloc grown on different carbon sources.
The objective of this study was to document the immunological effects of growing shrimp in biofloc systems. The experiment consisted of four types of biofloc systems in which bioflocs were produced by daily supplementation of four different carbon sources, i.e. molasses, tapioca, tapioca-by-product, and rice bran, at an estimated C/N ratio of 15 and a control system without any organic carbon a...
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...
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 کاملQuantitative role of shrimp fecal bacteria in organic matter fluxes in a recirculating shrimp aquaculture system.
Microorganisms play integral roles in the cycling of carbon (C) and nitrogen (N) in recirculating aquaculture systems (RAS) for fish and shellfish production. We quantified the pathways of shrimp fecal bacterial activities and their role in C- and N-flux partitioning relevant to culturing Pacific white shrimp, Penaeus (Litopenaeus) vannamei, in RAS. Freshly produced feces from P. vannamei conta...
متن کاملBiofloc 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)...
