“…Another study suggested 9 h as the maximum transport duration for spat to attain post-transport survival close to 100%, whereas higher tolerance to transport conditions was shown in the cold-water season . The transport duration of large spat can be increased to 12-24 h, implying appropriate conditions, but it has been recommended that the transport should take no longer than 12 h (Maguire et al 1999a;Minchin et al 2000;Christophersen 2000). A transport temperature below 12°C has been recommended and should be ≤10°C lower than the ambient seawater temperatures from where the scallops are removed .…”

The great scallop (Pecten maximus (L., 1758)) has been of interest for aquaculture in Europe since the early 1970s. Since then, a large part of the research and development has focussed on reproduction and early life stages to support hatchery production of spat. Results from the last two decades show that production stability is lacking and have followed a roller-coaster trend. Production strategy varies, but in general, broodstock are collected from the wild and conditioned to gonad maturity sufficient for successful spawning. Natural reproduction cycle varies between populations, which is a challenge to hatcheries aiming at stable year-round production. Larval survival was for many years dependent on addition of antibiotics until a flow-through culture was established, and seasonal variation may be caused by variation in gamete or seawater quality. Settlement, metamorphosis, and spat growth depend on healthy larvae and appropriate culture environment. For efficient spat production, the use of land-based nurseries is promising. Results show that mean yield of spat from eggs is less than 1%. The review concludes that the gap between results obtained in hatchery production and in experiments shows a great potential for production increase.Résumé : L'aquaculture européenne s'intéresse au grand pétoncle (Pecten maximus (L., 1758)) depuis le début des années 1970. Depuis lors, une partie importante de la recherche et du développement s'est concentrée sur la reproduction et les premiers stades de vie afin de favoriser la production de naissains en culture. Les résultats des deux dernières décennies montrent qu'il manque une stabilité dans la production et que les tendances ressemblent à des montagnes russes. Les stratégies de production varient, mais généralement le stock reproducteur est récolté en nature et conditionné jusqu'à la maturité des gonades pour obtenir une fraie réussie. Le cycle de reproduction naturelle varie d'une population à l'autre, ce qui présente un défi pour les cultures qui visent une production stable à l'année. La survie des larves a dépendu pendant de nombreuses années de l'addition d'antibiotiques jusqu'à qu'on mette au point une culture avec système de circulation; la variation saisonnière peut être due à la variation dans la qualité des gamètes ou de l'eau de mer. La fixation, la métamorphose et la croissance du naissain dépendent de la santé des larves et de la présence d'un milieu approprié de culture. Pour une production efficace du naissain, l'utilisation de nourriceries en milieu terrestre est prometteuse. Les résultats indiquent que le rendement moyen du naissain à partir des oeufs est de moins de 1 %. Notre rétrospective conclut que l'écart entre les résultats obtenus par aquaculture et en laboratoire montre qu'il existe un fort potentiel pour l'accroissement de la production.[Traduit par la Rédaction]

Post-transport recovery of cultured scallop (Pecten maximus) spat, juveniles and adults

et al. 2007

High mortality associated with transport operations in scallop culture has been a major problem faced by European farmers. Simulated transport with Pecten maximus L. spat \2 mm, spat 15-30 mm, juveniles 30-50 mm and adults [100 mm were carried out in Spain, Ireland and Norway. Different time and temperature combinations were studied in order to maximise post-transport survival and establish best practices. Out-of-water transport could result in 100% survival if conditions were right, but the response to emersion stress depended on size, season and location. Post-transport recovery decreased with emersion time and was strongly influenced by temperature. Air exposure was tolerated for a longer time by adult scallops than spat and juveniles, but the results differed among trials in the different countries. The maximum emersion time that gave posttransport survival ‡80% was 12 h for the smallest spat, 18 h for larger spat and 24 h for juvenile and adult scallops. Adults were less affected by transport temperatures that deviated from ambient seawater temperature than spat and juveniles. In general posttransport recovery was high when sea temperature was \10°C, but during warm-water seasons special care should be taken to avoid stressful and lethal transport conditions. A transport temperature \12°C was recommended, though not more than 10°C below ambient culture temperature. A maximum transport time of 9 h was suggested for spat and juveniles to attain post-transport survival close to 100%, but 12-24 h was feasible during the cold-water season or at favourable transport temperatures.
