4 success KEY of aquaculture farming

Fish, Algae, Water, Soil

To 'breed' the good fish, u have to 'breed' the good Algae!
To 'breed' the good Algae, u have to 'breed' the good water!
To 'breed' the good water, u have to 'breed' the good soil!


Last week, i received the phone call from my customer: "Ken, this year, finally i do not loss money!!" Meaning that he had make a big money from his shrimp farming project!

Congratulation, my frenz!! Haha, you should treat me a meal some day.

For this customer's example:

His ponds have produced around 
6480kg weight of shrimp ,assuming  the conversion ratio of 1:1, meaning he had put in 6480 kg feed food

Shrimp water content is around 70% (dry weight is 30%).

Conservative estimation: His pool has accumulated a total of 4500 kilograms of excrement, feces residue.

To assume biological digestibility efficiency = 50% ,
The total accumulation of the organic matters, feces residue will achieve a total weight of 4500/2 = 2250kg.

This just once farmed conservative estimation.
How does this particular pond going to digest this accumulated amount of 2250kg organic residue?
This residue will be putrefied by bad microbes and turn out become odor if not treated in proper way.
This poisonous leftover eventually act as disease causing substance
What about next time? Next Year if restart the farming?

Is it enough to just sun dry, apply lime to eliminate the bad microbes eliminated the odor smell?

All farmers are all aware of quality of pool water are highly dependent on the soil quality of pond.

According to this friend's practice, the steps are quite practical and effective.

1. Dry the soil under hot sun (Sterilization)

2. Dig and mix around 20 cm, dry again under sun. (sterilization, oxidation)

3. Sprinkle the lime on the soil (improved soil PH).

4. Apply bleaching agent 10PPM.

5. Apply Kucha meal. (Probably killed off all microbes )

6. 7 days after inserted the pond water, apply good probiotic in the water. ( to become dominant microbes in the pond and further digest the residue)

Noted, a total of 4 times killing the microbes ( good and bad microbes), the way is effective, just that it need time. There is better ways indeed:)
