Distribución del mercurio total en pescados y mariscos del Mar Argentino.
Provedor de dados: 20
Autores: Pérez, A.; Moreno, V.J.; Aizpun, J.E.; Malaspina, A.M.
Fish and shellfish samples for total mercury analysis were provided by the local fish export industry. Data collected through the years 1981-83 are processed and information was obtained on actual total mercury values in edible muscle of sampled species. On the basis of these results, future trends in mercury concentration values are hoped to be predicted. The authors suggest a revision of standards in force at present and the proposal of new ones, taking into account species involved and size of specimens.

Evaluation et cartographie des stocks de coquillages dans la partie marine de la région de Zarzis
Provedor de dados: 20
Autores: Ben Abdallah, O.; Ben Hadj Hamida, N.; Jarboui, O.
The experimental survey done, in august 2005, in coastal marine zone (0 - 20 m) of Zarzis showed the existence of numerous species of shellfishes of which Tricolia speciosa, Smaragdia viridis, Nassarius incrassatus, Cerithium vulgatum and Gibbulla umbilicaris are the most important gasteropods and, Pinctada radiate and Donax trunculus the main bivalves. The biomasses estimation, based on the method of swept area, in the studied zone showed that P. radiate is the most abundant species with about 20 000 tones, followed by C. vulgatum (7 645 tones) and T. speciosa (more than 1 000 tones). The Donax trunculus biomass is very low with only 13 tones. Finally, the abundance indexes distribution cartography permitted us to note that it varies from one species to...

Efecto del Flujo y el Seston sobre la Fisiología Energética del Callo de Hacha Atrina Maura (Sowerby 1835) y del Mejillón de Laguna Mytella Strigata (Hanley 1843)
Provedor de dados: 20
Autores: Galíndez, D.K.
Se examinó el efecto del flujo y seston sobre el callo de hacha Atrina maura y el mejillón de laguna Mytella strigata, bajo diferentes rangos de flujo y de exposición al flujo. En el primer experimento se usaron tres flujos (3.1, 7.3 y 12.1 cm/s) y en un tanque de circuito abierto durante 25 días, con agua proveniente de un estanque de cultivo de camarón y alta concentración de seston. Los mayores incrementos de las dimensiones de la concha, masas de tejidos e índice de condición de A. maura se obtuvieron a 7.3 y 12.1 cm/s, mientras que en M. strigata fueron a 3.1 cm/s. Los máximos contenidos de lípidos y acilgliceroles de A. maura en los tejidos se obtuvieron a los mayores flujos, mientras que en M. strigata, los máximos contenidos de lípidos y...

Autores: Ravn, H.
In this manual a review is provided of the chemical and toxicological aspects of Amnesic Shellfish Poisoning (ASP). The document contains information on chemical structure, chemical data, where to obtain standards and reference materials, the origin and occurrence, chemical analysis, mouse bioassay, epidemiology, mechanisms of action, symptoms and therapeutics. The practical use of this document has been highlighted in agreement with the Members of the Task Team on Aquatic Biotoxins. This document is prepared by Dr. H. Ravn, IOC together with Prof. T. Yasumoto, Tohoku University, Japan, Chairman of the Task Team on Aquatic Biotoxins. Dr. J. Ramsdell, National Oceanic and Atmospheric Administration (NOAA), Charleston Laboratory, USA has supplied parts of...
