“…The low numbers could be an under-reporting, as the harvest of scallops seeded on the bottom as juveniles for sea ranching or stock enhancement purposes may have been included in the fishery statistics. Other reasons can be irregularities in recruitment (hatchery and wild) or the occurrence of the algal toxin ASP in European waters that may have an impact on aquaculture of P. maximus (Campbell et al 2001;Blanco et al 2006aBlanco et al , 2006bBogan et al 2007aBogan et al , 2007bBogan et al , 2007cLiu et al 2007Liu et al , 2008.…”

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]

“…Moreover, most members of the Pseudo-nitzschia genus are elongated diatoms that are known for their ability to form chains (Hasle, 1994), thus possibly hampering shell growth by gill clogging. And, finally, Liu et al (2008) found negative impacts on growth rate and survival of juvenile Pecten maximus when exposed to food previously enriched with DA.…”

Palaeogeography, Palaeoclimatology, Palaeoecology, Elsevier, 2012, 373, pp.108-122. <10.1016/j.palaeo.2011 AbstractPhytoplankton dynamics in coastal oceans is a major component of the global biogeochemical carbon cycle, and is currently affected by global change through modifications in levels of primary productivity and composition of phytoplankton communities. Despite many attempts, no straightforward geochemical proxy has been found yet in marine biogenic carbonates for reconstruction of past phytoplankton dynamics with high temporal resolution. Here, we report on subweekly variations of lithium-to-calcium ratios (Li/Ca shell ) along the axis of maximum growth of great scallop shells ( Comparison of these results with shell growth measurements (increment width) and environmental parameters suggests (i) that shell calcification rate is likely the main factor controlling incorporation of Li in Pecten maximus shell calcite, (ii) that seawater temperature has only a weak positive influence on Li/Ca shell of this species over the range 8-18°C, and (iii) that during diatom blooms, additional amounts of Li may be trapped in the shell following dissolution of Li-rich frustules of edible species in the digestive tract of scallops, being responsible for Li/Ca shell peaks. Therefore, we suggest that Li/Ca shell ratio may be a novel proxy for timing and magnitude of diatom blooms in coastal ecosystems. Analysis of ancient shells may thus provide useful information on past phytoplankton dynamics and on the importance of recent shifts observed from diatoms to non-siliceous phytoplankton in coastal areas affected by anthropogenic activities.

“…The DA stock solution was prepared by dissolving DA in millipore water, and the equal volume of millipore water was added in the control. The experimental groups were exposed to DA at four concentrations (0, 10, 50, and 100 ng/mL), which were selected on the basis of previous studies reporting the toxicity of DA accumulation and its effects on juvenile scallops [19]. To maintain the DA concentrations, no water exchange or tank cleaning was performed during this experiment.…”

Domoic acid (DA) is an amnesic shellfish poisoning toxin produced by some species of the genera Pseudo-nitzschia and Nitzschia. This toxin has harmful effects on various species, especially scallops. This study aimed to investigate the effects of DA exposure on the immune and physical responses of bay scallop, Argopecten irradians. Various immunological and physical parameters were assessed (acid phosphatase (ACP), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), lipid peroxide (LPO), nitric oxide (NO), and the total protein content) in the haemolymph of scallops at 3, 6, 12, 24, and 48 h post-exposure to DA at different concentrations (10, 50, and 100 ng/mL). Moreover, the expression of immune-related genes (CLT-6, FREP, HSP90, MT, PGRP, and PrxV) was assessed. The activities of ACP, ALP, and LDH and the total protein content and LPO increased upon exposure to DA at different concentrations, while NO levels were decreased. Furthermore, immune-related genes were assessed upon DA exposure. Our results showed that exposure to DA negatively impacts immune function and disrupts physiological activities in bay scallops.
