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

10-1/2 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.
