“…Discussion All mussels consumed in the Basque region, during recent decades, are imported (Gracia 1996). Currently, the only way to cultivate mussels in the Basque Country is offshore and with submerged longline method (Azpeitia et al 2016). The aim of the study was to compare if experimental open ocean cultured mussels of commercial size were as competitive as local market leader of the same commercial size.…”

“…Higher ash content than open ocean mussels of this study were also observed in the same study in mussels from Ebro Delta and from Valencia (NE and SE Spain, respectively). Mussels cultured in the exposed environmental conditions (e.g., phytoplankton variability, strong hydrodynamics, and very marked seasonal changes in seston composition) may experience situations of stress or may have greater energetic expenditure (Azpeitia et al 2016) than mussels cultured in sheltered conditions. Oliveira et al (2015) found similar results when comparing open ocean mussels to sheltered cultured mussels.…”

Mussel shell biometry, nutritional quality as well as consumer sensory evaluation of experimental open ocean cultured mussel Mytilus galloprovincialis (Lamarck 1819) were analyzed and compared to that of commercial mussels from Galician Rías available in the local market. Both mussel products were of the same commercial size. In this study, open ocean mussels were significantly higher and wider than those of Galician Rías. In addition, with the exception of ash content, both mussel products showed similar biochemical composition. Regarding fatty acid profiles, however, statistical differences were detected. These differences were not fully reflected in the sensory assessment. In terms of consumer acceptability, both mussel products were considered equally satisfactory.

“…Open-ocean aquaculture represents a promising alternative for sustainable cultivation of bivalve species (Polk 1996;Hesley 1997;Stickney R 1998;Bridger and Costa-Pierce 2003), especially in regions with restricted coastal space for farming activities such as the Basque Country (Azpeitia et al 2016). Analyzing the health of wild mussel populations in relation to their reproductive cycle and spat production is important as mussel production relies on the annual collection of significant amounts of wild seeds, and farmers grow these seeds in extensive marine areas .…”

“…In a previous study, shellfish aquaculture had been experimentally tested in the open waters of the SE Bay of Biscay (Azpeitia et al 2016). The present study focuses on reproductive cycle and nutrient storage, and it is considered necessary to assess both sustainable exploitation rates for this species and potential capacity for aquaculture production in the region.…”

Variability of the reproductive cycle in estuarine and coastal populations of the mussel Mytilus galloprovincialis Lmk. from the SE Bay of Biscay (Basque Country)

Mussel commercial production depends on wild populations to obtain the seed. Therefore, any new farming initiative needs deep knowledge on reproductive cycle of native mussel populations. The reproductive cycle of Mytilus galloprovincialis Lmk. from five sites, three estuarine and two coastal, along the coast of the Basque Country were assessed using gonad index and stereology over 2 consecutive years (2010 and 2011). Sex ratios, developmental stages of gonads, as well as reserve tissue cycle were analyzed. The onset of gametogenesis was observed from winter to spring, with spawning occurring from spring till summer. A resting phase followed with an increase in reserve tissues (adipogranular cells) was observed in fall. Mussels stayed ripe during winter until favorable environmental conditions were met in spring. Differences in reproductive cycles were found among populations, and also, year-to-year variability was observed within each population. In two of the studied sites asynchrony in the timing of spawning was observed between genders. These timing differences, however, did not prevent mussels at those sites from reproducing successfully. The Bidasoa estuary points to the potential of such studied sites for becoming the main source of wild mussel spats for future expected commercial mussel farming in the Basque Country. To ensure year-toyear maximum reproductive output, however, wild mussels harvest should be avoided from spring to the end of summer in this region.

Since bivalves are filter-feeding organisms that can concentrate microorganisms and contaminants from the surrounding environment, there are strict sanitary requirements to ensure food safety. The legislation establishes a time limit of 2 months for shellfish relaying processes, but this study aims to determine whether the purification time can be reduced to make relaying an attractive activity for producers. For this purpose, mussels (Mytilus galloprovincialis) and Pacific oysters (Magallana gigas) were submerged for 6 weeks in a port near untreated urban discharges and then transferred to a relaying site located in open waters off the Basque coast (Southeastern Bay of Biscay). Salmonella spp. and Escherichia coli were analysed at 0, 2, 8, 14 and 21 days of depuration. After 2 days, Salmonella spp. was no longer detected in mussels or Pacific oysters. Geometric mean concentrations of E. coli (13068-14662 most probable number [MPN]/100 g) were high at the beginning of the experiment but decreased progressively. Pacific oysters needed 8 days to show E. coli values below the acceptable threshold for human consumption (230 MPN/100 g), while mussels needed 21 days. Under the studied conditions, the shellfish relaying period in open waters could be reduced while ensuring food safety.
