Since excreted feed nitrogen is bio-transformed efficiently in a fully functional mixotrophic biofloc technology production system, re-using this biofloc water over multiple production cycles should be beneficial. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production characteristics and mineral status, common microbial off-flavors, and water quality dynamics for channel catfish (Ictalurus punctatus) reared in one-year-old waters with low or high total suspended solids used previously for two consecutive catfish biofloc studies or in unused (new) water. Total suspended solids were maintained at 300 to 400 mg/L in the unused and low …
Effects Of Dietary Protein Content On Hybrid Tilapia (Oreochromis Aureus × O. Niloticus) Performance, Common Microbial Off-Flavor Compounds, And Water Quality Dynamics In An Outdoor Biofloc Technology Production System, Bartholomew W. Green, Steven D. Rawles, Kevin K.

Given tilapia grown in the biofloc technology production system can consume the biofloc, it should be possible to optimize formulated diet protein content to account for nutrition derived from consuming biofloc. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production indices, common microbial off-flavors, and water quality dynamics for hybrid tilapia (Oreochromis aureus×O. niloticus) fed diets formulated to contain 22.5%, 27.7%, and 32.3% digestible protein (DP) and 6% lipid. Fingerlings (32.2 ± 10.1 g/fish) were stocked in tanks (18.6m2; 16.6m3) in May 2016 at 25/m2 (29/m3) and grown for 5 months to market …
Effect Of Stocking Rate On Growing Juvenile Sunshine Bass, Morone Chrysops × M. Saxatilis, In An Outdoor Biofloc Production System, Bartholomew W. Green, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire
Effect Of Stocking Rate On Growing Juvenile Sunshine Bass, Morone Chrysops × M. Saxatilis, In An Outdoor Biofloc Production System, Bartholomew W. Green, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire

The biofloc technology production system is a production intensifying management strategy used primarily for culturing tilapia and penaeid shrimp, both of which can consume the biofloc. Other fish can be grown in biofloc systems because the biofloc serves to maintain water quality, metabolizing the ammonia excreted by intensively fed fish. A dose-response study was conducted in an outdoor biofloc system to begin quantifying the stocking rate-production function for sunshine bass, Morone chrysops x M. saxatilis, advanced fingerlings. Sunshine bass (2.9 ± 0.2 g/fish) were stocked into tanks at 50 to 250 fish/m2 in 50 fish/m2 increments. After …
