The folLowing, taken from A Manual of Fish Culture, published bythe United States Fish Commission, treats of the reproduction of the lobster: The principal spawning season for lobsters on the United States coast is summer,especially July and August, when probably three fourths of the lobsters deposit theireggs. The remaining egg-producing lobsters lay during the fall and winter. A givenlobster does not spawn oftener than every second year, as has been shown by recentstudies conducted by the Commission. The eggs are fertilized outside the body of the female. The spermatic fluid isdeposited in a receptacle at the base of the third pair of walking legs, and retains itsvitality for a long time.

Aftertheir discharge from the body the eggs become coated with a cement substancesecreted by glands in the swimmerets; this substance hardens after being in contactwith the water and firmly anites the eggs to the hair-like filaments on the swimmerets.The exact method by which the fertilizing principle is conveyed to the eggs from thepouch in which it is contained is not known. The incubative period is much prolonged. After the eggs are extruded andbecome attached externally, they are carried ten or eleven months before hatchingensues; during this time they are carefully protected, and are perfectly aerated bythe active motion of the swimmerets. On the United States coast most of the lobstersemerge from the eggs in June, although some of the hatching is completed in May
