Coenen's handwritten and illustrated books are of great cultural value and is full of texts from many different sources. For marine ecologists his own observations on fishes, fisheries and trade in the 16th century form the most valuable part. A contemporary 16th century account on the abundance of fish and on fisheries that took part, that's unique. A paper revealing this content, written by me with the help of fishery biologist Adriaan Rijnsdorp, appeared in press in 2015:

Bennema, F.P., Rijnsdorp, A.D., Fish abundance, fisheries, fish trade and consumption in sixteenth-century Netherlands as described by Adriaen Coenen. Fisheries Research 161 (2015) 384-399.

Earlier I dived into Coenen's sources about marine species which resulted in the scheme beneath. More info on Coenen's and other historic books may be found in the Timeline of marine biology before Linnaeus .
