Counting and weighing stock in large tanks

Recommended Posts

Hi ansihkgt,

I use to catch and weigh a sample number, say 20 fish out of 500... then calculate the average weight and then x 500.

Not only useful for adjusting feed rates, but also very important for assigning simple stocking density, transport density & container qty, medication, compound grow out and so much more.

Cheers
Joe

That's always been my approach as well.  It's not going to be perfectly accurate, but it's close enough to give the operator a good sense of the total fish mass in the system.  At the tilapia hatchery, this was an exercise we did about once a month.
