BULLETIN OF THE UNITED STATES FISH COMMISSION. 
(4) That the capture of berried lobsters be prohibited at all times. Though a law 
of this kind is sure to be more or less evaded, it is not expedient to encourage the 
destruction of eggs under any circumstances. 
A series of experiments should be tried in raising the young in spacious inclosures, 
where crowding in vertical and horizontal limits could be avoided, and where a natural 
supply of food could be provided, the object being to determine whether it is practi- 
cable to raise the young up to the fifth and sixth stages, when they go to the bottom 
and are able to protect themselves. If then set free, the chances of survival would be 
many hundred times greater than in the first stages. If we could save 100 instead of 
2 out of every 10,000 hatched, every 1,000,000 would give us 10,000 adults, and 
every 1,000,000,000 would yield 10,000,000 lobsters capable of reproduction. In such 
attempts to rear the lobster there are serious obstacles to be overcome in isolating the 
young, and giving them an abundant supply of pure water which shall at the same 
time yield the proper food, but we can not enter into the discussion of these subjects 
in this paper. 
The close period referred to above should begin about June 20, and extend five 
years and two months from that time to August 20. To illustrate it, we will say that 
it begins June 20, 1900, and extends to August 20, 1905. During this period 6 sets 
of lobsters would spawn; 2 of these sets would spawn three times, 2 sets would 
spawn twice, and 2 once. Thus the set spawning in 1900 would lay eggs again in 
1902, and again in 1904, and so on. Furthermore, the survivors of the broods of 1900 
and 1901 would be mature, or nearly so, at the end of this period in 1905.
