Table 2, The survival rates came from counting the number of fish.
In slurry pond, the stocking number of Tilapia was 821, but the number
of fish harvested was 9,080. Here a footnote was missing. It should add a
symbol of ** to indicate that there were 8,259 fingerlings, which were
self reproduced plus the stocked 821, and the total should be 9,080.

About Table 8, you are right. Small amount should be subtotal.
Thank you
