Diagnose pond microalgae species, dissolved oxygen crash risk, pH fluctuation, and corrective chemical liming/carbon actions based on observed pond water coloration.
Identified Water Color
Golden-Brown (Diatom Dominant)
Dominant Microalgae
Chaetoceros & Skeletonema diatoms
Biological Health Status
✅ Optimal Bloom (High Nutrition & Stable DO)
Secchi Transparency Rating
✅ Ideal Secchi Depth (25–35 cm)
Daily pH Fluctuation
0.5 pH units (✅ Stable Daily pH Range)
Corrective Field Action
Maintain bloom with light weekly dolomite (25 kg/acre) and fermented rice bran.
Phytoplankton is the primary producer of dissolved oxygen and natural shading. A healthy diatom bloom stabilizes temperature, inhibits pathogenic Vibrio, and reduces checktray feed waste.
Calculate total shrimp population, total biomass in kilograms and metric tons based on pond area, stocking density, average body weight (ABW), and estimated survival rate.
Determine total daily feed requirement in kilograms and break down feeding portions per meal based on total biomass, feed rate percentage, and feeding frequency.
Analyze checktray feed consumption time to determine whether to increase, maintain, or reduce feed rations by 10%.
Estimate how many grams of feed to place on checktrays per meal and expected clearing time based on shrimp body weight.
Compare your current Average Body Weight (ABW) against industry benchmark growth curves for Days of Culture (DOC).
Calculate total aeration Horsepower (HP) and paddlewheel/diffuser units needed to support expected pond biomass and maintain dissolved oxygen > 5 ppm.
