survivors was calculated on the basis of a constant mortality rate (see methods), fish size was modelled from growth curves constructed from samples at 2-day intervals, then fish body mass was backcalculated, using the model described in the methods. Finally, fish number and body mass were equated to determine how many nauplii
would have been needed to feed the survivors maximally on each day, and this value was compared to the number of nauplii that was actually distributed on this particular day. The results of this analysis (Fig. 6) clearly indicate that, at all fish densities, the fish that were offered 1 RFL were underfed throughout, except for the last feeding day, and even those given 3 RFL were slightly underfed from 60 to 108 hah.
