Juvenile rainbow trout were exposed to therapeutic concentrations of formalin or chloramine-T to assess the effects of these chemicals on the morphology of the piscine epidermis and its mucous coat. Repeated treatment, once weekly for 4 weeks, with either chemical did not affect the mucous coat of t...

Industrial depuration may provide a means of removing domoic acid toxin from blue mussels (Mytilus edulis ). Mussels containing up to 50 mu g domoic acid/g were transported from a Prince Edward Island estuary into controlled laboratory conditions to test the effects of temperature, salinity, mussel ...

Crenosoma vulpis and Eucoleus aerophilus are nematode parasites that can cause verminous pneumonia in wild carnivores. There is a paucity of information regarding the distribution of parasites in the lungs and the relationship between histopathological and parasitological diagnoses in naturally infe...

Domoic acid (DOM), the toxin involved in amnesic shellfish poisoning, was presented to live mussels (at 5 degree C, 28 ppt) in dissolved form (125 nM) and as food encapsulated in liposomes. Less than 1% of dissolved DOM and up to 6% of food-borne DOM was incorporated into mussel tissues. DOM absorbe...

Susceptibility to different diseases among related species, such as coho salmon (Oncorhynchus kisutch), rainbow trout (Oncorhyncus mykiss) and Atlantic salmon (Salmo salar), is variable. The prominence of these species in aquaculture warrants investigation into sources of this variability to assist ...

Studies on the microanatomy of the mucus-rich biofilm surface of normal or damaged teleost skin tissue have been limited because conventional fixation regimes do not effectively retain mucus during tissue preparation. A non-aqueous fixation method, based on a technique devised to retain airway mucou...

Lepeophtheirus salmonis is capable of causing severe damage to Atlantic salmon and this study was conducted to examine the physiological response of salmon to the stress of sea lice infestation. Smoltified salmon were acclimatized in 30% saltwater and exposed to high levels of lice infestation. The ...

Physiological, immunological and biochemical parameters of blood and mucus, as well as skin histology, were compared in 3 salmonid species (rainbow trout Oncorhynchus mykiss, Atlantic salmon Salmo salar and coho salmon O. kisutch) following experimental infection with sea lice Lepeophtheirus salmoni...

Cytokine genes in fish -- Environmental effects on the ontogeny of non-specific and specific defenses in turbot larvae -- Antibacterial proteins in skin mucus from rainbow trout -- Interferon-induced genes in the rainbow trout -- IPN recombinant vaccines -- DNA vaccination during low temperature and...
