Paralytic shellfish toxins inArgopecten purpuratusandSemimytilus algosusfrom northern Chile

Aquatic Living Resources, 2009
Within the framework of the Chilean molluscan shellfish safety program, blooms of Alexandrium were detected in several aquaculture sites in northern Chile. An outbreak of Alexandrium was detected in May 2006 in Mejil- lones Bay. Wild and cultured phytoplankton and shellfish samples from this bloom were analyzed by high performance liquid chromatography

Locomotion versus spawning: escape responses during and after spawning in the scallop Argopecten purpuratus

Marine Biology, 2009
The energetic cost of spawning and the endogenous factors that modulate spawning could modify escape response performance, leading to a conflict between the requirements of two fundamental components of fitness: reproduction and survival. We examined whether spawning changed force production during escape responses by the functionally hermaphroditic ...

Boom-to-bust. The scallop (Argopecten purpuratus) fishery in the Pisco-Paracas region, southern Peruvian coast

Espacio y Desarrollo, 2010
This paper examines scallop (Argopecten purpuratus) booms experienced in the Pisco-Paracas Region of southern Peru, triggered by the 1982-1983 and the 1997-1998 mega-El Niño Southern Oscillation (ENSO) events.

How healthy are cultivated scallops (Argopecten purpuratus) from Chile?: A histopathological survey [PDF]

Revista de biología marina y oceanografía, 2009
Scallop (Argopecten purpuratus) cultivation is an important economic activity in the central-northern region of Chile, and diseases are a permanent concern for farmers and fishing authorities. A one year-long survey was undertaken to find out what parasites and putative pathogens are present in cultivated scallops from three locations: Caldera ...
