G. portentosa: Feed mass per roach per week?


Recommended Posts

Hi all,

What is the mass of dry food that a typical adult G. portentosa hissing roach will eat over time? I am planning to feed dry food to a colony and I need to know exactly how much I will need. I have not been able to find any scientific literature with this value yet. Thanks!

Honestly, I am not sure if this information is even out there. I would personally just experiment around until I get it right.

I used some data on population by volume, reproduction rates, and the feed mass conversion efficiency of crickets to estimate the required feeding rates. It's not quite ideal, and I'm sure the mass required varies significantly based on the optimization of the diet and other factors, but at least I have something. I will make measurements when I finally build the enclosure, and hopefully clear up some of these numbers.
