“…Thus far no A. catenella blooms have been documented in northern Chile where the scallop fishery is well-developed. However, the scallop A. purpuratus was recently introduced into southern Chile, in the Los Lagos region (Gonzalez et al, 1999) especially near Chiloé Island, where massive A. catenella blooms have occurred recently (Molinet et al, 2003). A recent report also indicated the presence of Paralytic Shellfish Toxins (PSTs) in A. purpuratus from the bay of Tongoy and Guanaqueros (Á lvarez et al, 2009), two major locations of northern scallop aquaculture.…”

“…Scallop cultivation then started to be developed, mainly in Tongoy, Guanaqueros, and Caldera Bays (von Brand et al, 2006). Several trials have also been conducted to extend northern scallop aquaculture southward (Gonzalez et al, 1999). Northern scallop aquaculture represents a very important economic activity in northern Chile, with an annual production of 18,781 tons (von Brand et al, 2006), and any environmental stress, predator, or disease outbreak could jeopardize this industry.…”

“…In the Paracas Bay environment, particulate inorganic matter spikes could last for several days after a windy event (sandstorm type), which could explain the one week time-lag in our correlation. Temperature has often been identified as a key regulator of scallop growth (Broom and Mason, 1978;Wilson, 1987;Chauvaud et al, 1998;González et al, 1999;Laing, 2000;Wallace and Reinsnes, 1985;Macdonald and Thompson, 1986). Previous studies in the Paracas area indicated a positive effect of temperature on populations of A. purpuratus (Mendo and Jurado, 1993;Mendo and Wolff, 2003).…”

International audienceWe investigated the rhythm of micro-striae formation in the shell of Argopecten purpuratus and environmental influence on micro-growth increments by monitoring growth over a 98-day period between April and July 2007 under bottom and suspended culture (2m above the bottom) rearing conditions. The transfer of individuals to the study site induced the formation of a notable growth mark that allowed us to count the number of micro-striae formed between transfer and sampling dates. Micro-striae counts showed a deposition rate of one stria per day independent of rearing condition. This result allowed us to analyse the relationships between growth increments and environmental conditions. We therefore examined the deviations between observed growth rates and growth rates predicted from a Von Bertalanffy growth function. Cross-correlation analysis revealed significant correlations, without time-lag, between these deviations and both particulate organic carbon and nitrogen concentrations in the bottom treatment. Additionally, we observed negative correlations with temperature and current speed at this depth with time-lags of 1 and 10 days respectively. In the suspended treatment, we observed a significant negative correlation with temperature, only with a 12-day lag-time. Our results show that growth response to environmental variability is not always instantaneous. This delay can be explained by the time delay over which metabolic processes need to be performed (e.g. digestion, use/movements of reserves, growth, reproduction). Further modeling studies could help to better understand these processes

“…En A. purpuratus el crecimiento puede ser afectado tanto por factores bióticos como abióticos (Mendo & Wolff, 2003;Tarazona et al, 2007). Entre los bióticos está la disponibilidad de alimento y la composición de la dieta (Navarro et al, 2000), mientras que entre los abióticos la temperatura y concentración de oxígeno disuelto han sido mencionado como importantes (Wolff, 1987;González et al, 1999). Otro de los factores que influyen en las tasas de crecimiento son los eventos a gran escala como El Niño y La Niña.…”

RESUMEN.En Chile los cultivos del ostión del norte Argopecten purpuratus han sido desarrollados intensivamente a partir de la captación de semillas en ambiente natural y desde principios de 1980 con semillas obtenidas en hatchery. Para aportar información sobre el desempeño de semillas de ostión del norte en este estudio se comparó, mediante ANCOVA, el crecimiento en longitud entre cohortes producidas a partir de semillas de ambiente natural y de hatchery en Tongoy, Chile. Se evaluó la consistencia de esta comparación en distintos años y estaciones, comparándose parejas de cohortes producidas simultáneamente en los años 2003 (primavera) Comparison of growth among cohorts obtained Argopecten purpuratus larval recruitment in natural and hatcheryABSTRACT. In Chile crops of the northern scallop Argopecten purpuratus have been developed intensively from seeds obtained in natural environment, and since 1980 from hatchery's seed, when this technique could be controlled and developed. In order to provide information on the performance of seeds of northern scallops in this study growth in length between cohorts produced from seeds obtained in natural environment (CN) and hatchery (CH) in Tongoy (Chile) was compared using ANCOVA. We assessed the consistency of this comparison in different years and seasons. 2006 . These differences indicate that the cohorts of natural environment seeds grew faster than those of hatchery. Inter annual comparison showed significant statistical differences. These results are discussed in terms of the cultivation temperature and the heterozygosity for the growing population.
