Survival and growth of juvenile lobster Homarus gammarus L. raised for stock enhancement within in situ cages

The growth of juvenile lobster Homarus gammarus L. reared on sandy sediment s under laboratory conditions was compared with the growth of lobsters rear ed within in situ cages in the wild. The caged lobsters, left without any a ttention or care for 3 months, achieved an average size similar to that att ained under optimal laboratory conditions, (8.8 mm carapace length; CL). Gr owth was positively correlated to cage size and depth, Overall average surv ival was 66%, ranging from 0% to 90% for clusters of 30 individually caged juveniles.
