“…Thus, oysters, that experienced different selective pressures due to the fluctuating environmental conditions could mate and maintain high genetic variance over generations. Additionally, mortality differs according to culture techniques, with higher mortality in on-bottom than in off-bottom culture (Soletchnik et al,, 1999). Furthermore, feral oysters (i.e., wild populations) represent a large biomass, estimated to be 23% of the cultivated oyster biomass in Marennes-Oléron Bay .…”

“…La estadística global para este bivalvo en 2010 arrojó una producción aproximada de 653,000 ton (Helm 2015). Sin embargo, desde hace varias décadas, se han documentado eventos de mortalidad masiva en diferentes países (Glude 1974, Soletchnick et al 1999, Cheney et al 2000 que afectan la industria acuícola de tal manera, que la producción total en 2013 disminuyó más de 15%, lo cual fue equivalente a un volumen de cosecha de 556,000 ton (Helm 2015). C. gigas fue introducido en la década de los años '70 en varios estados de México (Baja California, Sonora, Sinaloa y Nayarit) y cultivado con éxito hasta finales de los años '90.…”

ARTÍCULORelación del crecimiento, condición y supervivencia del ostión del Pacífico Crassostrea gigas y las variables ambientales, cultivado en suspensión en el sistema lagunar Navachiste-Macapule, Sinaloa, México Abstract.-Evaluation of potential culture sites represents a 'good practice' alternative to support the development of oyster industry at the northeast of Mexico. The relationship of growth, condition and survival of Crassostrea gigas with the environmental parameters was studied at the Navachiste-Macapule lagoon system (Sinaloa, Mexico) from November 2011 to November 2012. The culture was carried out using 2,520 small oysters (3.5 ± 0.5 mm shell height) in a suspended longline system. The environmental parameters and oyster biometrics were sampled each 15 days. The mean values were: temperature= 25.01 ± 5.29°C, dissolved oxygen= 6.10 ± 1.93 mg L , respectively. After 13 culture months, the shell height reached 95.05 ± 9.21 mm, length 85.64 ± 20.01 mm, width 28.76 ± 10.91 mm, and the total weight 83.58 ± 17.18 g. The daily growth rate for the shell height and total weight were 0.25 mm day -1 and 0.23 g day -1, respectively. Significant differences were found for the total weight and the shell metric values throughout the culture. The final survival and mean condition index were 94.72% and 34.65 ± 4.46, respectively. Water temperature exerted a positive stronger effect on shell height and total weight. Results show that C. gigas reached the commercial size (80 mm SH) after 8 months of culture under the environmental conditions of the Navachiste-Macapule lagoon system, Sinaloa, Mexico. Obtained data contribute with basic information on further studies and commercial production cycles of this species in the region.Key words: Culture, suspended plastic trays, growth rate, Crassostrea gigas, mortality, MexicoResumen.-La evaluación de nuevos lugares con potencial de cultivo en la industria ostrícola representa una 'buena práctica' que contribuye con el desarrollo de esta actividad en el noroeste de México. Se realizó un cultivo en suspensión (long-line) con el ostión Crassostrea gigas para estudiar la relación de su crecimiento, condición y supervivencia con las variables ambientales en el sistema lagunar Navachiste-Macapule (Sinaloa, México), de noviembre 2011 a noviembre 2012. Se utilizaron 2.520 semillas (3,5 ± 0,5 mm de altura de valvas). Las variables físicas y químicas del agua, y biométricas del ostión fueron registradas cada 15 días obteniendo los siguientes valores promedio: temperatura= 25,01 ± 5,29°C; oxígeno disuelto= 6,10 ± 1,93 mg L -1 ; salinidad= 32,88 ± 2.15; pH= 7,82 ± 0,39 y profundidad= 1,66 ± 0,55 m. Las concentraciones de sólidos suspendidos totales, materia orgánica particulada y clorofila a variaron de 41,94 a 125,22 mg L -1

Development and distribution of the non-indigenous Pacific oyster (Crassostrea gigas) in the Dutch Wadden Sea

Pacific oysters (Crassostrea gigas) were first observed in the Dutch Wadden Sea near Texel in 1983. The population increased slowly in the beginning but grew exponentially from the mid-1990s onwards, although now some stabilisation seems to be occurring. They occur on a variety of substrates such as mussel beds (Mytilus edulis), shell banks, dikes and poles. After initial settlement spat may fall on older individuals and congregate to dense clumps and subsequently form reefs. Individual Pacific oysters grow 3-4 cm long in their first year and 2-3 cm in their second year. Many mussel beds (Mytilus edulis) are slowly taken over by Pacific oysters, but there are also several reports of mussel spat settling on Pacific oyster reefs. This might in the end result in combined reefs. Successful Pacific oyster spat fall seems to be related to high summer temperatures, but also after mild summers much spat can be found on old (Pacific oyster) shells. Predation is of limited importance. Mortality factors are unknown, but every now and then unexplained mass mortality occurs. The gradual spread of the Pacific oyster in the Dutch Wadden Sea is documented in the first instance based on historical and anecdotal information. At the start of the more in-depth investigation in 2002, Pacific oysters of all size classes were already present near Texel. Near Ameland the development could be followed from the first observed settlement. On dense reefs each square metre may contain more than 500 adult Pacific oysters, weighing more than 100 kg per m 2 fresh weight.
