| Avaliou-se na Universidade Estadual Paulista (UNESP) em jaboticabal, a presenca de microorganismos nas silagens de graos umidos de milho. Os tratamentos constaram de cinco percentagens de sabugo na silagem (0,5,10,15 e 20% na materia verde) e quatro periodos de amostragem apos a abertura dos silos (0,2,4 e 6 dias), em esquema fatorial, num delineamento inteiramente casualizado, com tres repiticoes. O crescimento de laactobacilos foi maior na silagem exclusiva de graos. A presenca de clsstrideos diferiu entre os tratamentos, com valores entre 1,30 e 3,32 oog UFC/g de silagem. A presenca de leveduras enterobacterias aumentoueem funcao das proporcoes de sabugo e dos periodos de amostragem. A populacao de lactobacilos foi satisfatoria para uma boa fermentacao... |

| Precision of abundance index estimation Merluccius hubbsi is directly related with the variability that normally occurs during the fishing operation and consequently in the geometry of the net duringeach haul. Some of these factors can be controlled, therefore the standardization of the sampling methodology avoids differences in the behaviour and 'work' of the net minimizing variations in the catchability between hauls. The acoustic equipment (SCANMAR) in there search vessels, allows to monitore the fishing operation during the trawl and to develop strategies in order to reduce the variability and to improve the precision of the estimations. The applicability of the methodology and there for the validity of the estimates indifferent cruises must be studied... |

| Une évaluation du gisement d'oursins du golfe du Morbihan a été réalisée en 2008.Six stations ont été échantillonnées : Stibiden, Roc'h Vihan, Port Blanc, Kerners, Hent tenn et Brannec, une station de plus que les années précédentes Pour les cinq stations communes à 2007 et 2008 l'augmentation de la population d'oursins est de 5 % en global et de 25% pour les individus commerciaux. Les densités totales varient entre 87 et 136 individus pour 100 m2 et les densités commerciales entre 56 et 87 oursins pour 100m2. La densité maximale d'oursins commerciaux a été observée à Port blanc. Les tailles des oursins s'échelonnent entre 22mm et 88mm. 63% des oursins échantillonnés avaient une taille supérieure à la taille de première commercialisation, soit 55mm. |

| The aim of the project "rationalization of biological sampling for stock assessment of marine fisheries in the bay of Biscay" is to perform statistical methods and computer programs allowing to test prognoses and diagnoses based on estimates of fishing mortalities, recruitments, yields per recruit, and the "gain-loss" function. The project gathers the laboratories of the community working on the Bay of Biscay fisheries, namely - Santander in Spain (1. E. 0) - La Rochelle and Lorient in France (IFREMER). A descriptive study has been carried out. The prepared documents contain a description of the procedures used to collect the information, by each of the laboratories involved, on: - landings - biological samplings. More comprehensive data have been gathered... |
