Total questions: 10
Worksheet time: 5mins
Define water quality in aquaculture terms.
water quality describes the condition of the water, including chemical, physical, and biological characteristics, usually with respect to its suitability for a particular purpose such as drinking or swimming.
water quality is a critical factor in aquaculture because it directly affects the health and growth of aquatic organisms, such as fish, shrimp, and shellfish. Maintaining appropriate water quality parameters is essential for successful aquaculture operations.
Good water quality is needed for maintaining . . .
viable aquaculture production.
aquaculture livestock.
aquaculture activity.
What are the effects of poor water quality in aquaculture?
low profit, low product quality and potential human health risks.
fish stunted growth, fish unwilling to eat and diseases breakout.
Is it important to choose good locations for aquaculture activities?
Yes
No
What is the value of dissolved oxygen (D.O) in water quality parameter?
mg/L
oC
g/L
Which of the following water quality parameters fluctuate daily?
dissolved oxygen and pH
temperature and dissolved oxygen
dissolved oxygen and salinity
What is ectothermal?
an animal that maintains its body temperature by absorbing heat from the surrounding environment
an animal that contain higher temperature than the surrounding environment
What is the saturation level of dissolved oxygen?
2 mg/L
3 mg/L
4 mg/L
5 mg/L
what is the effect if the pH level is 9.0-11.0 in aquaculture pond?
acid death point
no production
slow growth
alkaline death point
Why is total alkalinity important in aquaculture?
it can protects the organisms from major fluctuations in pH.
it can help to stabilize the fish health in the pond.
it can help in maintaining dissolve oxygen in the water
