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
DFR = NS x Survival x ABW x FR
DFR = NS + Survival + ABW + FR
What does NS stand for in the DFR formula?
Number of Stock
Net Stock
Nutritional Stock
New Stock
If the average body weight (ABW) is 200 grams, what is the DFR for 1,000 stocks with 60% survival and a feeding rate of 2.5%?
2 kilos
5 kilos
4 kilos
3 kilos
What is the first feeding time mentioned for the rations?
8 AM
6 AM
9 AM
7 AM
What is the implication of an FCR of 1.2?
1.2 kg of feed is needed for 1 kg of fish
Less feed is needed for more fish
More feed is needed for less fish
1 kg of feed is needed for 1.2 kg of fish
If 225 kg of feed is used to harvest 187.5 kg of fish, what is the FCR?
0.83
1.2
1.5
2.0
If the price of feed per kilogram is Php 40.00, and the FCR is 1.2, what is the feed cost per kilogram of fish?
Php 40.00
Php 44.00
Php 48.00
Php 50.00
If the number of stock (NS) is 1000, the survival rate is 60%, the average body weight (ABW) is 200 grams, and the feeding rate (FR) is 2.5%, what is the Daily Feed Ratio (DFR)?
1 kg
2.5 kg
3 kg
5 kg
What does the term "Survival Rate" refer to in the DFR formula?
The percentage of feed that is consumed.
The percentage of fish that survive until harvest.
The percentage of water that is replaced daily.
The number of fish that are stocked in the pond.
What would be the FCR if 158 kg of feed is required to produce 98 kg of fish?
1.5
1.2
1.3
1.6
Which of the following is a potential implication of a high FCR?
It indicates more efficient feed usage.
It suggests lower profitability due to higher feed costs.
It leads to a higher survival rate for fish.
It means less feed is needed to produce fish.
How does the survival rate affect the Daily Feed Ratio (DFR)?
A lower survival rate increases the DFR.
A higher survival rate reduces the DFR.
A lower survival rate reduces the DFR.
Survival rate has no effect on the DFR.
Which factor is NOT directly used in the calculation of the Daily Feed Ratio (DFR)?
Average Body Weight (ABW).
Number of Stock (NS).
Feeding Rate (FR%).
Water temperature (WT).
