Facts and observations on the salmon.

In the following observations I intend to offer some remarks on the various migratory fish of the genus Salmo; and then some facts and opinions which tend to show the importance of some change in the laws which are now in force regarding them.

We have first the Salmon; which, in the Ribble, varies in weight from five to thirty pounds.  We never see the fish here before May, and then very rarely; a few come in June, July, and August if there are high floods in the river, and about the latter end of September they become tolerably abundant; as the fisheries near the mouth of the river have then ceased for the season, and the Salmon run very freely up the river from that time to the middle or end of December.  They begin to spawn at the latter end of October, but the greater part of those that spawn here do so in December.  I believe nearer the source of the river they are earlier, but many fish are seen on the spawning beds in January; and I have even seen a pair so late as March; but this last is of very rare occurrence.
