Five sites representing a broad range of fish pass types were selected for trials. Camera, lighting and image recording equipment were deployed at each site, to identify the optimum combination and arrangement to produce the best fish images. The resulting video output was used to develop and evaluate three computer-based image analysis systems for detecting fish from video images. Two of these significantly [outperformed] the third in terms of detection rate for fish and time taken for an analyst to obtain a fish count.... The project generated [a] fish counting system... suitable for fish passes and narrow channels...  2, record 1, English, - fish%20counting%20system

La présence de barrages crée deux incidences potentielles sur les populations d'anguilles : la restriction de l'accès à l'habitat en amont et la mortalité dans les turbines durant l'avalaison. [...] La mortalité par avalaison des anguilles argentées migrantes est en fonction de la taille des anguilles (les plus grandes étant plus souvent tuées que les petites), de la dimension du barrage (en général, les petits barrages tuent proportionnellement plus d'anguilles)[,] du type, de l'espacement et des conditions de fonctionnement des turbines.  2, record 2, French, - mortalit%C3%A9%20en%20aval

Electrical resistivity fish counters... counting fish by noting changes in the electrical resistivity of water through which they swim was pioneered by Lethlean. The basis of his approach was to apply a low voltage across two volumes of water through which the fish to be counted are constrained to pass and detect the changes in their resistances caused by the presence of the fish... This device [electrical resistivity fish counter] amplifies the "out of balance" voltage caused by the presence of fish, passes this signal through logic circuitry and activates an appropriately labelled digit meter.  1, record 8, English, - electrical%20resistivity%20fish%20counter

Un compteur à résistivité pour poissons [...] fonctionne grâce à la différence de conductivité entre l'eau et le poisson. Les capteurs sont du type «tunnel» ou «canal ouvert». Dans le premier cas on oblige par un ouvrage associé le poisson à traverser un tube de forme circulaire ou prismatique équipé d'électrodes; dans le second cas les électrodes sont disposées sur le fond de la rivière dans le sens transversal, et fixées la plupart du temps sur le parement aval d'un seuil en béton [...] Le principe de mesure est bien connu : [...] la conductivité de la chair du poisson [...] étant différente de la conductivité de l'eau [...], le passage d'un animal entre les électrodes provoque une variation des impédances et par conséquent un déséquilibre du point de mesure. Le signal recueilli est ensuite amplifié et traité par une unité logique.  3, record 8, French, - compteur%20%C3%A0%20r%C3%A9sistivit%C3%A9%20pour%20poissons
