The effectiveness of interpretive methods in informal educational facilities : an experimental study with reference to marine parks

Interpretation has been used in many tourism sectors as a technique in achieving building hannony between resources and human needs. The objectives of this study are to identify the types of the interpretive methods used, and to evaluate their effectiveness, in marine parks. This study reviews the design principles of an effective interpretation for marine wildlife tourism, and adopts Drams' five design principles (1997) into a conceptual framework. Enjoyment increase, knowledge gain, attitude and intention change, and behaviour modification were used as key indicators in the assessment of the interpretive effectiveness of the Vancouver Aquarium (VA) and Marineland Canada (MC). Since on-site research is unavailable, a virtual tour is created to represent the interpretive experiences in the two study sites. Self-administered questionnaires are used to measure responses. Through comparing responses to the questionnaires (pre-, post-virtual tours and follow-up), this study found that interpretation increased enjoyment and added to respondents' knowledge. Although the changes in attitudes and intentions are not significant, the findings indicate that attitude and intention changes did occur as a result of interpretation, but only to a limited extent. Overall results suggest that more techniques should be added to enhance the effectiveness of the interpretation in marine parks or self-guiding tours, and with careful design, virtual tours are the innovative interpretation techniques for marine parks or informal educational facilities.

Dominion Marine Association records, 1972-1986

Established in 1903, the Dominion Marine Association was formed as an association of Canadian shipping companies. The Association had two main objectives. The first was to protect and advance the interests of Canadian shipowners, as well as Canadian consumers and exporters, to the extent that these interests are affected by government legislation and regulations. The second objective was to promote navigational safety through use of the latest technology, and through the continuous progress of vessel design. In 1988, the Association changed its name to the Canadian Shipowners Association.

Identification de composés naturels contre Saprolegnia sp., un champignon pathogène en aquaculture

La saprolégniose est une maladie fongique causée par le champignon aquatique Saprolegnia sp. qui affecte les poissons sauvages et ceux provenant des piscicultures. L’apparition de touffes cotonneuses semblables à de la ouate de couleur blanche à grise est souvent la première indication de l’infection. Ce saprophyte ubiquitaire se nourrit habituellement des œufs de poissons morts, mais peut se propager rapidement aux œufs sains causant la mort de ces derniers. La saprolégniose est souvent une infection secondaire, mais des souches virulentes peuvent facilement se développer sur les salmonidés ayant subi un stress ou une mauvaise manipulation. De grandes pertes économiques associées à la saprolégniose sont rapportées chaque année à travers le monde surtout dans l’industrie de la pisciculture. Jusqu’en 2002, le contrôle de la saprolégniose pouvait se faire par l’utilisation du vert de malachite, un colorant organique ayant une grande activité antifongique. Malheureusement, cette molécule a été bannie à cause de ses propriétés cancérigènes. Aucun composé aussi efficace n’est actuellement disponible pour traiter les infections de la saprolégniose. Des molécules ou extraits naturels ayant un potentiel antifongique ont donc été testés à l’aide de deux techniques (par graines de chanvre et par cylindre d’agar). Les molécules d’un extrait de propolis (cire de ruches d’abeilles) démontrant de l’activité anti-Saprolegnia ont été identifiées. De plus, une bactérie, Pseudomonas aeruginosa, pouvant être retrouvée dans le même environnement que Saprolegnia sp. a démontré un effet antagoniste au champignon. Une molécule de signalisation intercellulaire produite par P. aeruginosa, 4-hydroxy-2-heptylquinoline (HHQ), a été identifiée comme responsable de l’effet antagoniste contre Saprolegnia sp.
