Mr. Tod Stoddart, who is an authority on the salmon question, and particularly on matters relating to angling, says that a river like the Tay or the Tweed requires 15,000 pairs of breeding-fish to keep it in stock, the average weight of the breeders to be ten pounds each. Proceeding on these data, and taking the period of growth of the fish as previously stated, it may be interesting if we inquire how soon a fine river like the Severn could be made a property. Allowing that there is at present a considerable stock of breeding fish in that river—say 10,000 pairs—and that for a period of two years these should be allowed a jubilee, the river during that time to be carefully watched; that plan alone would soon work a favourable change; but if supplemented by an extensive resort to artificial nurture and protection, in the course of three years the Severn would be, speaking roundly, a mine of fish wealth. A series of ponds capable of breeding 1,000,000 fish might, I think, be constructed for a sum of £2000; there ought of course to be two reception-ponds, so that a brood could be hatched annually. [See plan in “Fish Culture.”] Thus, in a year’s time, half a million of well-grown smolts would be thrown into the river from the ponds alone, a moiety of which in the course of ten weeks would be saleable grilse! Next year these would be doubled, and added to the quantity naturally bred would soon stock even a larger river than the Severn. There can be no doubt of the practicability of such a scheme. What has been achieved in Ireland and at Stormontfield can surely be accomplished in England. An ample return would be obtained for the capital sunk, and in all probability a large profit besides. A recent report of the Inspectors of the English Fisheries embraces a summary of the condition of ninety rivers; and I can gather from it that considerable progress has already been made in arresting the decay of these valuable properties, and that there is every prospect of the best rivers being speedily repeopled with salmon to an extent that will secure them, under proper regulations, from again falling into so low a condition. A careful perusal of this report shows that fixed nets have been nearly abolished; that portions of rivers not hitherto accessible to fish have been made so, passes and gaps having been created by hundreds. Poachers have been caught and punished with great success; and, according to a review of the report in the _Field_, a journal which is well versed in fishery matters, “salmon have been seen in large quantities in places where they have not been seen these forty years.”
