PERCH THEIR FECUNDITY. 39 







THE PERCH (Perca fluvialitis) flourishes in both 

 stagnant and running water. In the former they are 

 more commonly numerous ; the river perch are, how-

 holes and the slower reaches of large rivers are their 

 chosen resorts. They are extremely hardy, flourish-
