“…Large family variation in survival (10-40%) in the previous experiments (Jørstad et al 2001) and the size range (23-28 mm TL) in the present study are comparable New Zealand Journal of Marine and Freshwater Research, 2009, Vol. 43 to observations in similar experiments carried out with American lobster, Homarus americanas (Van Olst et al 1980;Aiken & Waddy 1995). The low overall survival observed in the present study suggests a high level of competition among the families and groups, which is also supported by the relative low frequency (53.7%) of juveniles with 2 claws (Table 2).…”

Experiments were carried out from June 2000 to April 2001 to compare survival of European lobster (Homarus gammarus) offspring (larvae and juveniles) from three brood sources, Kvitsøy Wild (KW), Kvitsøy Cultured (KC), and Rogaland Wild (RW), Norway. In the first set of experiments, newly hatched larvae (stage I) were raised in separate family tanks. All larvae groups survived to stage III/IV, although large variation in relative survival was observed among families within each of the three different female groups. Highest overall survival was observed for the RW group (12.8%), whereas no differences in overall survival were found between the KW (9.0%) and KC groups (9.6%). From stage III/IV, larvae from single family tank experiments were mixed in five "common garden" juvenile experiments. These lasted for 9 months, and the surviving juveniles were identified to family/female group using microsatellite DNA profiling. Significantly higher survival of the KW families (7.0%) was found compared with the KC (3.7%) and the RW families (3.2%), and differences in family ranking of relative survival values were evident between the KW and KC groups. The relative survival rate of the different groups was independent of female lobster size. An estimate based on only stage IV larvae reduced the difference in survival between the KW (11.4%) and KC (8.3%) group. The experiments provided evidence that cultured females (KC) are producing viable offspring with lower, but comparable survival to that of offspring from wild females (KW).

“…The culture facility, built in 1993 (Charmantier and Haond 1994), is based on rearing techniques developed for the production of lobsters in hatcheries (Van Olst et al 1980;Aiken and Waddy 1995), with tanks for holding berried females, 10 40-L plankton-kreisels for larval culture (Hughes et al 1974), and two partitioned raceways for holding postlarvae and juveniles. Running seawater (salinity ranging from 33‰ to 38‰) is supplied to the culture facility.…”

Intracellular free amino acids were measured in the abdominal muscle of the three larval instars, postlarvae, and juveniles of the lobster Homarus gammarus, acclimated to seawater (35 per thousand) and to a dilute medium (22 per thousand), to study intracellular isosmotic regulation throughout the development of this species. Transfer to low salinity was followed by a highly significant drop of free amino acids level in all developmental stages. The main regulated amino acids were glycine, proline, and alanine. The level of regulation of total free amino acids changed at metamorphosis: the decrease in total free amino acids at low salinity was 46% in the three larval instars, but it was only 29% in postlarvae and 20% in juveniles. These results suggest that free amino acids, mainly glycine, proline, and alanine, are involved in intracellular isosmotic regulation in the lobster, with different levels of involvement in pre- and postmetamorphic stages. The ontogenetic changes in intracellular isosmotic regulation are discussed in relation to the changes in extracellular regulation (osmoregulation) in the lobster.

“…Initial attempts to culture both the European (H. gammarus) and American (H. americanus) lobsters were begun independently over 100 years ago (Nicosa and Lavalli, 1999;Van Olst et al, 1980) and these have been developed since this time.
