Problem 1:
Acidic soil and low water pH (under 4) cause serious problems in aquaculture.
Problem 2:
Benthic or filamentous algae during water preparation.
Problem 3:
Turbid water prevents a healthy phytoplankton bloom and blocks the shrimps’ gills.
Problem 4:
An unstable bloom may indicate problems with alkalinity, pH and/or nutrient levels.
Problem 5:
Over-blooms will create problems with oxygen levels, black gill and H2S.
Problem 6:
A water color change indicates the plankton is starting to die, or the species is changing.
Problem 7:
A low pH limits plankton growth, and makes hydrogen sulfide more toxic.
Problem 8:
Black sludge indicates anoxic bacteria that produce toxic hydrogen sulfide gas.
Problem 9:
Bad odor can indicate a problem with hydrogen sulfide or VFAs.
Problem 10:
The level of toxicity of ammonia rises with temperature and pH.
Problem 11:
Nitrite becomes more toxic in a pond with low salinity.
Problem 12:
A drop in feed consumption means longer culture time and potentially lost profits.
Problem 13:
Pink shell or gill indicates stress. Something is wrong in the pond environment.
Problem 14:
White muscle is abnormal. It indicates stress or disease.
Problem 15:
White fecal strings indicate a bacterial or parasite infection.
Problem 16:
Loose Shell Syndrome (or LSS) is a slow killer of shrimp, hurting farmers’ profits.
Problem 17:
Sometimes a crop suddenly dies – without ever showing any sign of disease.
Problem 18:
It is common for a crop in a poorly managed pond to experience illness during the first month.
Problem 19:
A failed molting means death for the shrimp.
Problem 20:
An algae over-bloom means plankton can easily crash and drop oxygen levels.
