Hi SanuFurther to my comments above.It would appear that moderate training actually reorganizes metabolism so as to spare the muscle [against muscle loss] in many teleost's including tilapias (Belal, 2015) with the result that protein growth is promoted over lipid growth in fish that are both fed and continually swum (Christiansen et al., 1989; Lauff and Wood, 1997). The Belal (2015) study indicat ...

Hi Sanu. A recent study entitled, “Effect of Water Velocity on Tilapia, Oreochromis niloticus Fingerlings Growth Parameters and Body Composition” (Belal, 2015) looked at horizontal water velocities in fingerling Nile tilapia production. A velocity range of 20-35cm/sec was considered optimal, although lower FCR’s were recorded at a velocity of 25cm/sec as opposed to 35cm/sec where the higher veloc ...

Hi NeilThe only way to maximize throughput production relative to maximum carrying capacity is via the management of a single tank system as a multi-cohort sequential stock management system. This we call the Production: Capacity Ratio (P:C ratio). Apart from reduced CAPEX per unit fish production, the benefits filter down to energy costs for aeration, carbon dioxide stripping and horizontal water ...

Good Day RayI am finding this concept fascinating. The multicohort, leading to partial harvesting, was something that I modeled for our Dusky Kob and it makes economic sense.I am intrigued to find out in practice how the screens, that are used to divide the tank for the different GSs, impact on the flow rate and subsequent solids removal. Do you also have any metrics to share on the percentage oxy ...
