In a footnote in table 2 you mentioned that adult fish occupied 62.1% of the
harvest in the slurry loaded pond.

Does this figure consider the reproduction of tilapia?

According to table 2, in the manure loaded pond the average harvest weight
of tilapia was 100.2 grams.

What was the average weight for adult tilapia in the slurry loaded pond and
what is the commercial size of Tilapia in China?

I understand that some of the ponds in China cannot be totally emptied.
How do you deal with tilapia reproduction in these ponds?

Could you comment about the benefits of Tilapia introduction to Chinese aquaculture?.

Thanks in advance
