This book was released on 1984 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'examen des ecailles de 3 200 saumons echantillonnes dans trois secteurs du reseau Koksoak, en Ungava (Quebec, Canada), de 1979 et 1981, a permis de constater l'existence d'un type particulier de marque hivernale apres la smoltification dans plus de 20% des cas. L'information disponible permet de demontrer que la disposition serree des circuli qui forment ces marques traduit un confinement hivernal a l'interieur du reseau Koksoak, pendant lequel la croissance en longueur devient presque nuile. Les saumons estuariens vierges se distinguent de ceux qui reviennent de la mer par leur maigreur, au debut de l'ete, et par une frequence moindre de l'ectoparasite Lepeophtheirus salmonis. Il semble que l'abondance relative des saumons a croissance estuarienne et mixte ait augmente dans la recolte, entre 1960 et 1980.

This book was released on 1990 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE METABOLISME ENERGETIQUE A ETE ETUDIE CHEZ LES JUVENILES DE SAUMON ATLANTIQUE (PARRS ET SMOLTS), SIMULTANEMENT EN CONDITIONS DE METABOLISME STANDARD ET DE ROUTINE. LES MODIFICATIONS QUI SURVIENNENT AU COURS DE LA SMOLTIFICATION ONT ETE INTERPRETEES EN FONCTION DES VARIATIONS DU FACTEUR THERMIQUE (ISOENZYMES) ET DES FACTEURS ENDOCRINIENS QUI SOUS-TENDENT CE PROCESSUS. L'ACTION STIMULANTE MAJEURE DU METABOLISME ENERGETIQUE APPARAIT RESULTER D'UNE POTENTIALISATION DE L'EFFET DE L'HORMONE DE CROISSANCE PAR LA TRIIODOTHYRONINE. IL A PU ETRE ETABLI QUE LES MODIFICATIONS DU METABOLISME STANDARD, CONSECUTIVES A DES TRANSFERTS D'EAU DOUCE EN EAU DE MER, ETAIENT DIFFERENTES SELON LE NIVEAU D'ADAPTATION AU MILIEU MARIN ACQUIS PAR LES SMOLTS: DIMINUTION CHEZ LES PRESMOLTS, AMPLIFICATION AU TERME DE LA SMOLTIFICATION. CES EFFETS RESULTENT ESSENTIELLEMENT DES MODIFICATIONS DU METABOLISME INTERMEDIAIRE INDUITES PAR L'AUGMENTATION DE SALINITE AMBIANTE. DE PLUS, LE SURCOUT ENERGETIQUE DE L'OSMOREGULATION SERAIT PLUS FAIBLE QUE CE QUI ETAIT ADMIS JUSQU'ALORS. PARALLELEMENT, A ETE MISE EN EVIDENCE UNE DIMINUTION DU METABOLISME DE ROUTINE, INTERPRETABLE COMME UNE ADAPTATION COMPORTEMENTALE A UNE LIMITATION DES POSSIBILITES D'APPROVISIONNEMENT TISSULAIRE EN OXYGENE. CHEZ LE SAUMON ADULTE, LE TRANSFERT INVERSE D'EAU DE MER EN EAU DOUCE INDUIT UNE DIMINUTION DU METABOLISME ENERGETIQUE, UNE AUGMENTATION DE LA CAPACITE DE DIFFUSION GAZEUSE DES BRANCHIES, AINSI QUE DES MODIFICATIONS DES CONCENTRATIONS IONIQUES PLASMATIQUES ENTRAINANT UNE ALCALOSE DU COMPARTIMENT EXTRACELLULAIRE ET UNE AUGMENTATION DE L'AFFINITE DE L'HEMOGLOBINE POUR L'OXYGENE. CES EFFETS POURRAIENT CONSTITUER DES PROCESSUS ADAPTATIFS POUR LA MIGRATION ANADROME

This book was released on 1993 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.
