Cause of Problem : Excess feed or fish waste Algae bloom or plankton overgrowth Soil disturbance from fish activity or rain Poor water management.

Effect on Fish : Low oxygen (DO decreases) Fish become stressed

Reduced feeding and slow growth

Risk of disease or death

Difficulty for fish to see

food

Suggested Solution : Use aerator to increase oxygen

Do partial water exchange

Reduce feeding amount

Remove excess waste/sludge

Monitor water quality regularly

Roleplay Summary : Technician reported low oxygen level.

Specialist explained fish are stressed and gasping.

Manager decided to install aerator and reduce feeding.

High Ammonia

Cause :

Over feeding and waste accumulation

Effect on Fish :

stress

potential death

reduce growth

Solution :

remove remaining excess excreted

change water regularly

Dissolved oxygen is low

Cause :

1. Poor aeration

2. Overfeeding

Effect on fish :

1. Fish are gathering at the water surface

2. Fish are not eating well

Solution :

1. Increase aeration

2. Reduce feeding

Role play summary :

Technician reported low DO , specialist explained fish stress , and manager decided to increase aeration immediately, environmental officer suggest long term control, operations staff monitor fish and water conditions, maintain equipment and take quick action.

High water temperature

Cause:

Temperature too hot and low of oxygen

Effect on fish:

High metabolism means fish required more oxygen demand

Solution

-add shade

-install aeration

Role play summary:

TECHNICIAN report high temperature,specialist explained fish metabolism is high and need more oxygen,manager decide to install black net for shade and install aeration.

Water salinity is too high.

Causes:

• Compound of undergrounds minerals

• Mixing between the seawater and freshwater

Effects on fish:

• Fish may die because they cannot tolerate the salinity.

Solution:

• Liming to reduce salinity of the water

• Temperature control to reduce evaporation.

• Effective Microorganism (EM) to breakdown salt ions.

pH is low (6 acid)

Cause:

rain falls into a fish pond and the fish pond will become acidic so it causes slow fish growth

Effect on Fish:

Fish growth slows down

Solution:

• Stabilize the pH of the water by adding limestone

• Installing a translucent roof

🎭 Role Play Summary:

Technician reported low reading pH, specialist explained fish behavior, environment officer suggested long-term controo and manager decided to stabilize the pH of the water
