| A Dynamic Energy Budget (DEB) model for simulation of growth and bioenergetics of blue mussels (Mytilus edulis) has been tested in three low seston sites in southern Norway. The observations comprise four datasets from laboratory experiments (physiological and biometrical mussel data) and three datasets from in situ growth experiments (biometrical mussel data). Additional in situ data from commercial farms in southern Norway were used for estimation of biometricalrelationships in the mussels. Three DEB parameters (shape coefficient, half saturation coefficient, and somatic maintenance rate coefficient) were estimated from experimental data, and the estimated parameters were complemented with parameter values from literature to establish a basic parameter... |

| A spatially explicit coupled hydrodynamic-biogeochemical model was developed to study a coastal ecosystem under the combined effects of mussel aquaculture, nutrient loading and climate change. The model was applied to St Peter's Bay (SPB), Prince Edward Island, Eastern Canada. Approximately 40 % of the SPB area is dedicated to mussel (Mytilus edulis) longline culture. Results indicate that the two main food sources for mussels, phytoplankton and organic detritus, are most depleted in the central part of the embayment. Results also suggest that the system is near its ultimate capacity, a state where the energy cycle is restricted to nitrogen-phytoplankton-detritus-mussels with few resources left to be transferred to higher trophic levels. Annually, mussel... |

| The composition and seasonal variation of brachyuran and anomuran species associated with mussel farms were evaluated at Praia da Cocanha, São Paulo between May 2007 and February 2008. Nine mussel ropes were sampled at random in each quarter, and 1,208 organisms were identified, comprising five families and 28 species. The most numerous species was the porcellanid Pachycheles laevidactylus (18.5%), followed by the xanthids Acantholobulus schmitti (16.6%), Hexapanopeus paulensis (11.3%), Panopeus americanus (10.2%), and Menippe nodifrons (8.4%). The exotic crab Charybdis hellerii was recorded throughout the study period. The ecological descriptors, except Pielou evenness index, varied significantly over the time. The highest abundance and diversity of the... |

| It is understood that the rate of bioaccumulation and subsequent depuration of heavy metals in marine animals is influenced by the chemical state, as well as the kinetics of transformation between different species of chemical salts dissolved in water. The Indian Brown mussel, Perna indica, was exposed to copper nitrate and chloride, individually, to analyse the rate of accumulation, depuration, oxygen uptake and filtration rates. When supplied in very low quantities, environmentally realistic concentrations, the rate of accumulation of copper nitrate and chlorides showed variations. When the animals were transferred to sea water, these two salts did not show any clear cut differences in the depuration rate. Irrespective of the previous accumulation... |

| The effect of thinning on the harvestable biomass of mussel Mytilus platensis (d'Orb.) cultures was analyzed. Mussels were grown on ropes in sub-surface long-lines in Golfo Nuevo (Chubut, Argentina, 64° 59' W; 42°46' S) during a 15 month period (January 1987-April 1988). Ropes were seeded using the Spanish method with 2,000 individuals per rope meter. The thinning-out was performed three months later using the following thinning ratios (TR: number of half-grown ropes obtained from one seed rope):1,6 (900 individuals m super(-1)), 2,4 (600 individuals m super(-1)) and 3,2 (450 individuals m super(-1)). Growth rate (shell length and meat weight), survival and number of harvestable ropes increase with the thinning rate; the harvestable biomass being larger at... |

| Los hidrocarburos aromáticos policíclicos (HAPs) son contaminantes alimentarios y su toxicidad se debe a que algunos de ellos son conocidos cancerígenos humanos, clasificados en el grupo dos de la Agencia Internacional de Investigación sobre el Cáncer (IARC). La determinación de los niveles de estas sustancias en los alimentos, especialmente en productos de la pesca, se ha incrementado en los últimos años por diversas causas. El objetivo de este estudio fue la determinación de los hidrocarburos aromáticos policíclicos (HAPs) en mejillones (Perna viridis) de la Bahía de Cienfuegos, 50 especímenes de mejillón con dimensiones entre 80-100 mm de largo antero-posterior de concha, se homogeneizaron y se tomó una muestra de 5 g de peso fresco, se trataron con... |
