“…total lipids content of 163 g kg −1 was relatively low in relation to the published range of 200-350 g kg −1 (dry weight) for this genus. 36,37,45 Without stressful conditions, the Picochlorum fatty acids pattern was very typical, as described by Mourente et al 46 which showed high proportions of short-chain polyunsaturated fatty acids, with C16:2 (3.5%), C16:3 (8.6%), C18:2 (10.5%), C18: 3 (15.3%) as major fatty acids and the absence of C18:0 and C18:1.…”

“…showed an equilibrium between C16 and C18 fatty acids with a predominance of unsaturated (71%) fatty acids; most of them are polyunsaturated (69.5%), such as linolenic acid ( ω ‐3) (26.5%) and linoleic acid ( ω ‐6) (23.5%). It was reported that Nannochloris and Chlorella species showed high proportions of short‐chain polyunsaturated fatty acids and low levels of long‐chain highly unsaturated fatty acids, such as C20:5 or C22:6 . Matsumoto et al reported that Chlorella sp.…”

“…There are species-specific and family variations in biochemical cell content, especially in the fatty acid profile (Mourente et al 1990;Dunstan et al 1994;Brown et al 1997;Jacobsen et al 2010), but algal growth phase also affect cell content (Fidalgo et al 1998).

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]

“…Lipid composition and productivity depend on growth conditions such as growth phase (Xu et al, 2008), medium composition (Valenzuela‐Espinoza et al, 2002), irradiance (Thompson et al, 1993), and temperature (Renaud et al, 2002). Qualitatively, the profiles of fatty acids (FAs), ranging in length from 10 to 24 carbons, are often similar between species of the same phyla or classes but differ greatly between classes and phyla (Hu et al, 2008; Mourente et al, 1990) from low‐yield cyanobacteria to oleaginous (oil‐rich) species/strains from eukaryotic algal taxa (Hu et al, 2008). With the exception of cyanobacteria, lipid content increases significantly in all microalgal taxa under nitrogen‐limiting conditions (Hu et al, 2008).…”

Biomass and lipid productivity, lipid content, and quantitative and qualitative lipid composition are critical parameters in selecting microalgal species for commercial scale-up production. This study compares lipid content and composition, and lipid and biomass productivity during logarithmic, late logarithmic, and stationary phase of Nannochloropsis sp., Isochrysis sp., Tetraselmis sp., and Rhodomonas sp. grown in L1-, f/2-, and K-medium. Of the tested species, Tetraselmis sp. exhibited a lipid productivity of 3.9-4.8 g m(-2) day(-1) in any media type, with comparable lipid productivity by Nannochloropsis sp. and Isochrysis sp. when grown in L1-medium. The dry biomass productivity of Tetraselmis sp. (33.1-45.0 g m(-2) day(-1)) exceeded that of the other species by a factor 2-10. Of the organisms studied, Tetraselmis sp. had the best dry biomass and/or lipid production profile in large-scale cultures. The present study provides a practical benchmark, which allows comparison of microalgal production systems with different footprints, as well as terrestrial systems.
