Abstract:
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–2 ; means were 72 in 1998 and 55 in 1999. As expected, the fastest growth was
found in tanks with heated water (15–19˚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.
