Anybody know what the average 10 - 15cm trout weight is?

Trying to work out estimated feed for 11 trout. I'm working off 60g per fish at 2% body weight = approx 13g twice a day. Does this sound about right?

Ciao Signore, I fished this out of my thread on around page 4 or 5, as I had similar questions when I got my trout back in March. I have since eaten 2 a few weeks ago which were ~27-30cm long and 300g each. The other 23 are doing fine and continuing to grow. I still use the calculator as a rough guide, but some days they don't want much and others they smash it.

"I was trying to work out the weight of my yearling trout based on their length, and stumbled across this trout feed calculator https://docs.google.com/spreadsheets/d/ ... edit#gid=0 in this thread viewtopic.php?f=26&t=12411&start=15 which gave me 47 grams/day for 25 fish at ~20cm long at ~19oC, which is half of what I gave them yesterday. I will stick with the calculator for a while as they seem to be growing even on the very short rations of the past week, and the piggies seem like they will eat until they burst so feeding until they stop doesn't seem like the way to go."

Hope that helps

Thanks a bunch joc. Looks like I work out be be around 15g for the day.
