How to calculate abundance of species that overlap between two sampling tools?

10 March 2016 1 3K Report

In order to sample macrobenthos and benthic fish, two fishing tools were used, dredge (non-static, in sediment) and net (non static, above sediment).

What to do with species that overlap between the two tools (they are caught with both tools)? what is the correct way to calculate their abundance ?

Thanks for your help!

Uwe, thank you for the answer. I was thinking the same: based on species ecology choose the appropriate tool, and avoid underestimation or double counting.
