when the lake is quiet and there is less chance of people or pets swimming in areas being surveyed
.

Fish are more intelligent than they appear
. In many areas, such as memory, their cognitive powers match or exceed those of ‘higher' vertebrates including non-human primates.” Fish's long-term memories help them keep track of complex social relationships.
How long fish stay underwater?
Like us, fish need oxygen to survive. But to breathe, most pull oxygen-containing water into their mouths and pump it through their gill chambers before expelling it out of their gill slits. Now, for the first time, scientists have seen fish “holding” that breath, some for
