(1695) I have also frequently heard it said that the Fish called Sturgeon feeds on water and wind , a statement to which I could not give any credence at all .I therefore resolved to buy the first Sturgeon ( which rarely appears in our market ) so as to see , if possible , what sort of food it took , and since in the Late Summer a living Sturgeon , not quite two feet long , was offered for sale , I bought it for the sole purpose of seeing what its stomach contained , and saw in it many pieces of The intestines then have a darker colour and a strong smell .In the case of the Zuiderzee herring some of the fishes were already spent in March .
