Adriaen Coenen (Scheveningen, 1514-1587) was a Dutch fish merchant and auctioneer of sea fish and also amateur ichthyologist because of his interest in everything in the sea lived.
The Visboeck Coenen is a 16th-century manuscript richly decorated with colored illustrations. These provide modern researchers working knowledge about the 16th century fisheries, such as when the nets in use, then the fishing boats and the time to take in the sea fish. Apart from that the Visboeck also [includes] descriptions of insects, sea spirits, dragons, native and exotic animals, natural phenomena and miracles.
