Estimating Metabolism of Fish in Aquacultural Production Systems. International Journal of Recirculating Aquaculture, 4. DOI: http://doi.org/10.21061/ijra.v4i1.13791547-917Xhttp://hdl.handle.net/10919/90591Open-system respirometry offers a practical approach for measuring metabolic rates of fish cultured at high densities in uncovered raceways. Central to this methodology is analysis of a dynamic mass-balance on oxygen supply and demand. Here, we present a validated mass-balance equation, describe minimally disruptive procedures for estimating its parameters, and illustrate its use in estimating the oxygen-uptake rate of fish as a group, in real time and under actual production conditions.8 pages961.45 KBapplication/pdfenIn CopyrightMetabolism of FishRecirculating AquacultureArticle - RefereedCommercial Fish and Shellfish Technologies Program, Virginia Techhttps://doi.org/10.21061/ijra.v4i1.1379412572-9160
