The choice of verb for English here will depend to some extent on who you think κανείς refers to.  The writer here is making a complaint - people who should be interested, are not interested.  (Most people are not interested anyway, as these animals are not part of our daily lives).  So what group of people are we talking about?  ερευνητές?  κυνηγούς?  αρμόδιους?  τοπικές αρχές?  ψαράδες?
