Suspended solids are measured using Imhoff settling cones. Superintensive Culture of White Shrimp Litopenaeus vannamei in a Biofloc Technology System in Southern Brazil at Different Stocking Densities.
Shrimp PL10 2 001 mg were reared in biofloc system fertilized with inorganic and anaerobic and aerobic carbon process with a microbial mix for 45 days at a density of 3000 shrimp m-3. The formation of biofloc is. Biofloc technology BFT has been studied at several Furthermore the authors also noted that shrimp grown in a occasions and contributes to the maintenance of good water biofloc environment harbored a higher total antioxidant quality in the system and to the nutrition of the cultured capacity both in the plasma and hepatopancreas.
BFT Biofloc system is at present highly sought technology for Pacific white shrimp culture due to high efficiency productivity sustainability and with lower FCR. It summarizes the results of simulations of various production scenarios using data derived from the indoor biofloc production runs conducted at the Texas AM-AMRL and described in earlier sections of this manual. 2013 reported that the application of biofloc technology on Pacific white shrimp super intensive culture considerably enhanced N and P utilization efficiency up to 70 and 66 respectively relative to conventional intensive culture systems with regular water exchange.
For all the described shrimp culture systems AFT highly recommend the use of an Closed Recirculating System CRS. Design and Operation of Super-Intensive Biofloc-Dominated Systems for the Production of Pacific White Shrimp. The system was successfully applied in.
There are over 50 indoor shrimp farmsand growing. Biofloc technology has not only been applied at commercial shrimp grow-out farms but also in super-intensive raceways to produce more than 9 kg shrimpm3. Culture in extreme water conditions freshwater and high salinity.
Closed Recirculation Systems CRS A closed recirculation system can be used in existing semi-intensive systems and in super-intensive systems. The raceway applications have supported nursery and then grow-out to shrimp broodstock rearing and selection of family lines. Da Silva et al.
The use of biofloc technology for super-intensive shrimp production is emerging as a sustainable alternative to traditional shrimp culture. Biofloc Workshop WAS Seattle WA February 10 2014. The cone is filled allowed to settle for 1020 minutes and reading taken by reading the graduations on the cone.
