ARTIFICIAL PROPAGATION OF THE LOBSTER

The rapid increase in the catch of this crustacean during the past ten years has drawn upon it the most earnest attention of all interested in the preservation of this valuable fishery. If the "berried" or female lobster bearing eggs, and the young and immature, were let alone by the fishermen there would be no necessity for a resort to artificial lobster culture. Maine has a most stringent law forbidding the taking and selling of "berried" lobsters, and of any lobster under 10½ inches in length, but this law is evaded by numerous fishermen whenever possible. An idea of the extent to which short lobsters are marketed in the State may be gathered from the statement of Mr. A. R. Nickerson, commissioner of sea and shore fisheries for the State, that in 1899 over 50,000 short lobsters were seized and liberated by the State wardens. As these wardens only discover a small proportion of the short lobsters handled by the fishermen and dealers it is easy to see what a terrible drain this is on the future hope of the fishery—the young and immature. Large numbers of "berried" lobsters are also captured, the eggs brushed off, and the lobsters sold as ordinary female lobsters.

The Report of the U. S. Fish Commission for 1897, on pages 235 and 236, contains the following account of the artificial propagation of lobsters:

Prior to 1885 experiments had been conducted at various points looking to the artificial propagation of the lobster. The only practical attempts of this nature previous to those made by the Fish Commission were by means of "parking," that is, holding in large naturally inclosed basins lobsters that had been injured, soft-shelled ones, and those below marketable size. Occasionally females with spawn were placed in the same inclosures. One of these parks was established in Massachusetts in 1872, but was afterwards abandoned; another was established on the coast of Maine about 1875. It was soon demonstrated, however, that the results from inclosures of this character, so far as the rearing of the lobsters from the young were concerned, would not be sufficient to materially affect the general supply. The completion of the new marine laboratory and hatchery at Woods Hole in 1885, with its complete system of salt-water circulation, permitted the commencement of experiments in artificial hatching on a large scale which had not been practicable theretofore, although small quantities of lobster eggs, as well as those of other crustaceans, had been successfully hatched. In 1886 the experiments had progressed so successfully that several million eggs were collected and hatched at Woods Hole, the fry being deposited in Vineyard Sound and adjacent waters. From 1887 to 1890, inclusive, the number of eggs collected was 17,821,000.

During the above years the average production of fry was about 54 per cent. By the use of more improved apparatus the average was brought up to 90 per cent in 1897, when the collections amounted to 150,000,000 eggs, of which 135,000,000 were hatched. As the commissioner of sea and shore fisheries of Maine objected to the taking of female lobsters in that State and the planting of part, at least, of the resulting fry in other waters, an arrangement was made in 1898 by which all female lobsters and the fry hatched out from the eggs secured from these would be returned to the State waters. Under this arrangement 2,365 "berried" lobsters were bought from the Maine fishermen by the U. S. Fish Commission. From these 25,207,000 eggs were taken and 22,875,000 fry were hatched. Of these, 21,500,000 were deposited in Maine waters at various points. In 1899, 36,925,000 fry were planted in Maine waters by the Commission. In order that the female lobsters may be secured the authorities of Maine permit the fishermen to catch and sell "berried" lobsters to the Commission.

The collection of eggs in Maine is usually made by the Commission during the months of April, May, June, and to about the middle of July, depending upon the supply to be had. During the season of 1899 a small steam smack was chartered for collecting the lobsters, starting from Gloucester, where the hatching of Maine lobster eggs is now carried on, and running to Eastport, returning over the same route. The Fish Commission schooner Grampus was also used in this work. The lobsters are purchased from fishermen, who receive the market price for ordinary lobsters, and as they are not allowed to sell these lobsters legally for consumption the sale to the Commission materially increases their financial returns.

In 1883 a radical advance along the line of artificial propagation was made, so far as the legislature was concerned, when the act incorporating the Samoset Island Association, of Boothbay, was passed. Section 4 of the charter reads as follows:

In order to secure a sufficient and regular supply of lobsters for domestic consumption on any land or islands under the control of said corporation, it may increase the number of lobsters within said limits by artificial propagation, or other appropriate acts and methods, under the direction of the fishery commission, and shall not be interfered with by other parties, but be protected therein, as said fishery commission may determine, and shall have the right, by its agents and tenants, to take and catch lobsters within 300 yards of the low-water line of the islands and lands owned or leased by said corporation, during each and every month, for domestic use.

In 1887 the legislature passed an act granting R. T. Carver the sole right to propagate lobsters in Carver's pond, Vinalhaven. Mr. Carver's experiment was a failure, as he says the mud in the pond was so filthy that nearly all the spawn was killed.
