What reading level is Montana Wildlife Vol Apr 1963 book?
To quickly assess the difficulty of the text, read a short excerpt:
EFFICIENCIES The chief difficulty in studying fish is not in just getting a sample of fish, al- though getting representatives of each kind that lives in a body of water may be difficult enough in itself. The real problem lies in defining the relationship between the sample and the over-all pop- ulation. In other words, a section of stream has been electrofished and one hundred fish have been taken. What do these one hundred fish represent — ninety percent of the population? Ten percent?
or wha...t?
When shocking small streams the ma- jority of the fish, especially those over three inches long, are taken. Only rarely is it practical to try to collect all the fish from a section of stream by electrofishing.
The efficiency of capture (the percentage of fish present that are captured) varies greatly with the size of fish and with dif- ferent water types. As mentioned, larger fish are more easily captured than smaller ones.
In careful studies, the efficiency of the shocker in taking fish from a particular water is determined.
