What does FCR stand for?

• Feed Cost Ratio

• Fish Conversion Rate

• Fish Consumption Rate

• Feed Conversion Ratio

What does the FCR indicate?

• The amount of fish produced

• The number of fish stocked

• The total cost of fish farming

• The effectiveness of feeds used

What is the formula for Daily Feed Ratio (DFR)?

• DFR = NS - Survival - ABW - FR

• DFR = NS / Survival / ABW / FR

What does NS stand for in the DFR formula?

• Number of Stock

• Net Stock

• Nutritional Stock

• New Stock
