T. pectoralis start weight gives the individual
weight of the fish at the beginning of the period
under consideration. The total fish stocking weight
comprises the combined weight of all fish stocked
within a plot. Survival rate of T. pectoralis,
B. gonionotus and C. carpio was calculated as the
percentage of stocked fish that could be captured
back at fish harvest. SGR of B. gonionotus, O. niloticus
and C. carpio was calculated as for T. pectoralis.
