In the Result and Analysis section you stated:

>Pond No. 1 was applied with 3,000 kg of slurry (2,000 kg as
>basal manure). Basal manure application: 8-10 d before stocking fry.
>Pond No. 2 was applied with 740 kg of chicken manure (200 kg as
>basal manure). Pond No. 3 was applied with 667 kg of night soil
>(500 kg as basal manure), 23.8 kg of soy bean in the form of soy
>bean milk, 9 kg of flour and 27 kg of duckweed
>(wet weight).

I found the results very interesting in terms of survival rate of sumerlings:

Could you please provide more information about the term "basal manure" and
how is the remaining amount applied to the pond?
