When fed at 10% body weight daily, newly weaned Australian
snapper Pagrus auratus fed 8 times a day had higher growth
and lower size heterogeneity than fed 4 and 2 times a day (Tucker
et al., 2006). Therefore, in the present study we investigate under a
constant nutrient input, namely, the feeding rate, if increasing
photoperiod can increase plant production, concomitantly, plant’s
filtering capacity and nutrient concentration in water and also if
increasing feeding frequency can even out through time, fish
metabolite and excrete, concomitantly, stabilize water quality and
increase fish production.
