There are four ongoing abundance indices for the upper St. Lawrence River and Lake Ontario system : a long-term count of juvenile eels ascending the eel ladder at the Moses-Saunders Power Dam, a trawl survey index in the Bay of Quinte(Lake Ontario), an index of abundance based on an electrofishing survey in eastern Lake Ontario, and dam tailwater surveys of emigrating adults at Moses-Saunders Power Dam. The first three, longer-term Ontario abundance indices, showed significant negative trends over the past 10 to 36 years, indicating that eels are at about 3% of their mid-1980s abundance, far from the objective of rebuilding stocks to mid-1980s levels. 1, record 1, English, - eel%20ladder

Les données de base sur les populations de saumon [...] n'ont pas bien été établies, et il existe de nombreux stocks de saumon sur lesquels on ne connaît pas grand-chose. [Le] projet a identifié des rivières repères [...] qui serviront d'information de base et qui orienteront la recherche et les stratégies de conservation et de gestion à l'avenir. Plus tard, diverses rivières repères pourraient constituer la base de la gestion des stocks de saumon et de poissons anadromes [...] Les rivières repères se sont avérées particulièrement utiles pour faire le suivi sur l'abondance de stocks de saumon et des caractéristiques des populations dans [certaines] régions. Les parties étudieront [...] une autre stratégie de gestion des stocks de saumon fondée sur les résultats de cette étude. 2, record 2, French, - rivi%C3%A8re%2Drep%C3%A8re

Numerical Habitat Models(NHM) have been developed to predict fish habitat quantity, quality and distribution under different flow regimes found in rivers. These models depend on the estimation of an Habitat Quality Index(HQI) at the scale of fish microhabitat. One of the problems of NHM is that mathematical constructs to estimate HQI in one river may not be applicable to other rivers. Hence, HQI are not transferable among rivers. The most common measures of HQI are based on indices of preference of fish for specific ranges of water depth, current speed and substrate composition(referred to as Habitat Suitability Indices; HSI). 5, record 4, English, - habitat%20quality%20index

Inspiré du «Habitat Suitability Index (HSI)», élaboré aux États-Unis, l'indice de qualité de l'habitat (IQH) est un modèle mathématique qui permet d'évaluer, pour une espèce faunique, la valeur en tant qu'habitats (milieu dans lequel une espèce animale donnée trouve, en quantité suffisante, les éléments biologiques et physiques nécessaires à sa survie et à sa reproduction) d'une série de peuplements forestiers. L'IQH ne sous-entend pas une certaine densité de population pour chaque classe d'habitat, c'est-à-dire que l'IQH ne donne pas une projection de la densité d'individus possible que l'on peut trouver dans un peuplement, mais il détermine la valeur de ce peuplement en termes d'habitats pour certaines espèces. 1, record 4, French, - indice%20de%20qualit%C3%A9%20de%20l%27habitat
