Dear Kangmin Li

In table 2, manure-fed pond received a stocking of fingerlings at 167.30
kg/mu while in the digested_pig_slurry-fed pond it had 85 kg/mu

Q: why do you use two significantly different stocking rates for the
fingerlings in the two ponds ?
Q: what is the general stocking rate for fish polyculture that is used by
fish farms in Jiangsu Province ?

chicken manure+grass fed pond had input by 30.645 t/ha and grass by 0.93
t/ha while digested_pig_slurry-fed pond of only 1090.8 t/ha

Q: why is the chicken manure input 30 times higher

Table 5 showed that the dissolved oxygen measurements in the two ponds did
not differ so much between the two ponds (except in May) despite a higher
loading manure than in the slurry pond. Could you explain why. If both
ponds have received the same aeration, then the manure pond should have a lower DO value ?

I believe the weight of fingerlings per ha for the chicken manure+grass
pond should be 2.508 t (not 1,375 t/ha).
