What reading level is Fish Culture in Ponds And Other Inland Waters book?
To quickly assess the difficulty of the text, read a short excerpt:
A plausible answer is that by so doing HATCHING TROUT 147 the little fish is enabled to keep more easily his gill- covers open and breathe. In fact the shell, dragging at the edge of the gill-covers, pulls them open and thus gives assistance to a safe delivery. If the little creatures were to emerge head first the shell would most likely press itself against the gill-covers, close them, and either smother the fish or leave it so weak that death would surely follow in a little while. Be this as ...it may, it is nevertheless a fact that the issuance of a fish in any other manner than tail foremost is indicative of premature or improper hatching, with early death as a result.
As the fry emerge, they fall through the long meshes in the trays to the bottom of the trough which at this time contains no gravel or sand.
They are then gathered daily, or oftener, by- means of a feather and scap-net, placed in pans of water and transferred to troughs previously made ready for them, the bottoms of which are covered with fine, well washed gravel.
