Hello,

Does anyone know how much food it takes to grow a single silver perch to plate size on average?

just trying to work out if/when an upgrade to my system would break even.

Thanks in advance

mine took about 3 years to reach 500g 30odd cm

Impossible to answer. Too many variables.

if you assumed a 2:1 feed ratio it would take 1kg to get a 500g silver, so thats a ball park figure +/- 100%

Thanks a bunch I'll use the 2:1 ratio to work out my costings

Try google for FCR for silver perch, that will give you a ball park figure. Stock density and yearly temps need to be considered.
