Aw. Fast et al., A NEW METHOD FOR ASSESSING FISH FEEDING RHYTHMS USING DEMAND FEEDERS AND AUTOMATED DATA-ACQUISITION, Aquacultural engineering, 16(4), 1997, pp. 213-220
A new approach to monitoring fish feeding rhythms and associated envir
onmental variables is described. This system includes demand feeders a
ttached to load cells to monitor feed consumption, and environmental p
robes to monitor variables such as temperature, solar radiation, barom
etric pressure, dissolved oxygen, turbidity, and pH. Measurements from
the load cells and probes are recorded at some desired time interval
on a data logger, and the data are then analyzed for correlations betw
een feed consumption and environmental conditions. An example of feed
consumption rhythms by Chinese catfish (Clarias fuscus) is given. (C)
