Fish and their behavior

Více o knize

"Fish and Their Behavior" not only provides the fishkeeper with a great deal of stimulation and plenty of tips, but will also give a fascinating insight into the subject of behavioral science for anyone. The reader accompanies the author through the secretive underwater world; he reads about fish that can even survive in salt and soda, about the unique flora and fauna of a freshwater lake that is the size of a sea in the heart of Africa and about inhabitants of the sea, where only the strongest turn into females. He is on the spot to tell us about how a scientist built himself a massive underwater house in the Red Sea and how American researchers follow the migration of salmon.
