The neurotoxin β-N-methylamino-L-alanine (BMAA) is naturally present in some microalgal species in the marine environment. The accumulation of BMAA has widely been observed in filter-feeding bivalves that are known to consume primary producers constituting the base of complex aquatic food webs. This study was performed to assess the occurrence of BMAA and isomers in mollusks collected from nine representative shellfish production areas located on the three French coasts (Channel, Atlantic and Mediterranean sites). The use of a highly selective and sensitive HILIC-MS/MS method, with D5DAB as internal standard, revealed the systematic detection of BMAA and DAB, in concentrations ranging from 0.20 to 6.7 μg g-1 dry weight of digestive gland tissues of... |

The feasibility of large-scale bloom induction of nutritionally suited natural phytoplankton species, to feed a semi-industrial nursery of edible shellfish, built on the Belgian coast, was tested. The outdoor microalgal production unit consisted of four tanks of 100 m² surface each (two of 1 m depth and two of 0.5 m depth), equipped with different mixing devices. The cultures were run as chemostats in which seawater was enriched with commercial inorganic N, P and Si fertilizers. Depending on the season, between 5-10 and 80% of the culture volume could be harvested daily, with algal densities ranging from 50,000 to 500,000 cells per ml. By manipulation of operational parameters such as detention time, nutrient levels and nutrient ratios (N: Si: P), unsuited... |
