N2  - A series of communal rearing experiments with European lobster (Homarus gammarus) performed in 1998 and 1999 at the Kvits&oslash;y Lobster Hatchery in Norway tested methods for future production of juveniles for farming and release purposes. Lobster larvae were raised from stage IV in tanks or cages with a bottom substrate of shell sand and a variety of shelters. Survival rates after 4 to 5 months ranged from 10 to 67%; averages were 59% in 1998 and 30% in 1999. Final densities ranged from 29 to a maximum of 130 juvenilesm&#8211;2 ; means were 72 in 1998 and 55 in 1999. As expected, the fastest growth was found in tanks with heated water (15&#8211;19&#x02DA;C), where mean carapace length (CL) was 17 mm after 4 months, compared to a mean CL of 11 mm in unheated water. Size at the end of the experiments was highly variable, even within the offspring from a single family, and especially in heated water. Lobsters raised communally were in general larger and more variable than were lobsters raised in single compartments.
