F3 Fish-Free Feed Challenge Calculations

	A	B	C	D
1		Species:	Carp / Tilapia	Carp / Tilapia
2
3			Typical Diet	Improved Diet
4		Species Production Amount (tonnes)	75,786.88	75,786.88
5		Feed Conservsion Ratio	1.6	1.6
6		Fishmeal % in Feed	2	0
7		Fish Oil % in Feed	0	0

9		Assumptions:
10		1. Forage fish used in calculations is Anchoveta (Peruvian anchovy):
11		% fishmeal	24	24
12		% fish oil	5	5
13		Average Weight (tonnes)	0.00001935	0.00001935
14		2. 33% of fishmeal and fish oil in average feed comes from byproduct, thereby reducing need for fishmeal and fish oil from whole forage fish by that amount
15
16	Step 1:	Calculate amount of feed needed (tonnes) for production amount
17		Species production amount * Feed Conversion Ratio	121,259.00	121,259.00
18
19		Amount of Fishmeal needed (tonnes) for production amount
20		Fishmeal rate of inclusion in Feed * Feed Needed	2,425.18	0.00
21		Amount of Fish Oil needed (tonnes) for production amount
22		Fish Oil rate of inclusion in Feed * Feed Needed	0.00	0.00
23
24	Step 2:	Calculate limiting ingredient using Forage Fish Dependency Ratio (FFDR)
25		FM FFDR: = Fishmeal rate of inclusion in Feed / Fishmeal % in Forage Fish	0.08	0.00
26		FO FFDR: = Fish Oil rate of inclusion in Feed / Fish Oil % in Forage Fish	0.00	0.00
27		Limiting ingredient is one with higher FFDR	Fish oil	N/A
28
29	Step 3:	Calculate the amount of Forage Fish Needed (tonnes)
30		FFDR of Limiting Ingredient * Feed Needed * 0.67	6,770.29	0.00
31
32	Step 4:	Calculate the # of Forage Fish Needed
33		Weight of Forage Fish Needed / Weight of a Single Forage Fish	349,886,003.45	0.00
34
35	Extra:	Calculate excess weight of non-limiting ingredient (tonnes)
36		1. Calculate amount of non-limiting ingredient created by amount of forage fish needed
37		Amount of Forage Fish Needed * Fish Oil % in Forage Fish	338.51	0.00
38		2. Subtract amount of non-limiting ingredient needed for production amount by amount of non-limiting ingredient created by amount of forage fish needed	338.51	0.00

41		FORAGE FISH SAVINGS
42		# Forage fish needed from Typical Diet - # forage fish needed for Improved Diet	349,886,003.45
