“…The higher larval mortality observed at the 70-cells/mL diet treatment could be related to a higher input of pathogens because of a higher amount of algae supplied. On the other hand, the depressed growth rate exhibited by larvae reared at 30 cells/mL might be related to an insufficient food supply, as has been observed in other pectinid species (Uriarte et al 2001b, MacDonald et al 2006, Merino et al 2009). …”

“…The use of closed recirculation systems is not common in bivalve rearing, but they have been tried on an experimental basis with nursery-sized A. r. irradians (Widman 1998) and northern quahog clams (Mercenaria mercenaria (L., 1758)) (Pfeiffer and Rusch 2000). Up to present the only tests on scallop larvae in recirculation systems was performed by Merino et al (2009) in Chile for the northern Chilean or Peruvian bay scallop (Argopecten purpuratus (Lamarck, 1819)). The results were promising and even though the experiment was done at variable temperatures, it showed high growth rates but variable survival.…”

“…Flow-through systems have been used for many years to culture several other marine larvae, such as Atlantic halibut (Hippoglossus hippoglossus (L., 1758)) (Harboe et al 1994), American lobster (Homarus americanus H. Milne Edwards, 1837) (Serfling et al 1974), and Pacific pearl oyster (Pinctada margaritifera (L., 1758)) (Southgate and Ito 1998). The next step in optimizing scallop larval rearing may be the use of recirculation systems as recently tried for A. purpuratus (Merino et al 2009). …”

Spat production of the great scallop (Pecten maximus): a roller coaster¹This review is part of a virtual symposium on current topics in aquaculture of marine fish and shellfish.

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]

“…Recirculating systems operate by water undergoing treatment, allowing to the hatcheries production system's waters to be partially reused (Rosenthal et al 1986). This technology has been widely used in fish culture for more than three decades (Rosenthal 1980;Verreth and Eding 1993;Martins et al 2005), but only recently has it been experimentally tested in nursery culture of some mollusk species such as Mercenaria mercenaria (Pfeiffer and Rusch 2000), Argopecten purpuratus (Merino et al 2009) and Pecten maximus (Magnesen and Jacobsen 2012).…”

Impacts of rearing techniques on growth, survival and bacterial microbiota of carpet shell clam (Ruditapes decussatus) larvae

In this study, we investigate the impacts of two water treatment regimes, the closed aquaculture system (CAS) and flow-through system (FTS), on the carpet shell clam (Ruditapes decussatus) larval microbiota, growth and survival. A bacteriological barrier (B) was created among breeder stage treated by florfenicol (FF, 8 mg L -1 day -1 per 5 days). After spawning, larvae were maintained in five different rearing techniques: CAS; FTS; B ? CAS; B ? FTS and B ? CAS ? FF (8 mg L -1 day -1 per 3 days). Significant decrease was observed in both total bacterial count and presumptive Vibrio count (PVC) in FF-treated breeders. Besides, larvae reared in B ? FTS showed significantly lower PVC than larvae maintained in other rearing techniques. It was also determined that growth and survival of larvae reared in B ? CAS ? FF and B ? FTS were significantly better than those reared in other systems. One hundred and twelve Vibrio strains, isolated from breeders, eggs and larvae, were subjected to some bacteriological tests (API 20E strips, vibriostatic agent O/129, growth at different temperatures and salinity). Vibrio alginolyticus was the predominant isolated species (36.61 %), followed by V. fluvialis (25 %), V. vunificus (17.86 %), V. cholera (13.39 %) and V. paraheamolyticus (7.14 %). These results may contribute to the understanding of the effect of rearing techniques on the bacterial load, survival and growth of early life stages of R. decussatus larvae.
