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

Indice d'abondance. Mesure quantitative de la densité ou de l’abondance du poisson, généralement exprimée en séries temporelles. Un indice d’abondance peut être spécifique d’une zone ou d’un segment de la population (par exemple, les grands poissons) ou désigner l’abondance au niveau du stock; il peut indiquer l’abondance en nombre ou en poids (biomasse). La plupart des indices d’abondance qui sont utilisés d’habitude par le SCRS [Comité permanent pour la recherche et les statistiques] sont fondés sur des données de CPUE [captures par unité d'effort] standardisée, même si on a également utilisé certains indices d’abondance, indépendants des pêcheries, qui se fondent sur des études scientifiques. Les indices d’abondance sont généralement exprimés en unités relatives (contrairement aux mesures de l’abondance absolue) et indiquent simplement les changements relatifs qui affectent l’abondance dans le temps.  1, record 4, French, - indice%20d%27abondance

Estimates of catch typically make up the bulk of the data that is applied to a stock assessment model. But most stock assessment models also require some kind of index of abundance. The index of abundance is a value that indicates the trend in relative abundance over time. Often[, ] an index of abundance is simply the number of fish caught during a survey. The index of abundance for a cod stock, for example, may be the average number of cod caught per tow from a research vessel. Each tow would be of a specified length, depth and speed using a standardized net, so that the index of abundance values could be compared over time.  3, record 6, English, - abundance%20index

Although habitat characteristics are fairly well defined, not all abalone habitat locations are known due to knowledge gaps in shoreline composition, and therefore there is no estimate for AO [the area within the extent of occurrence that is occupied by the species].

Carbon Preference Index(CPI). Generally the ratio of abundance of odd over even carbon number paraffins, specifically calculated over the C24-C34 range.

With increasing maturity, and odd-even preference (also known as CPI: carbon preference index) of about 5:1 in shallow detrital material is reduced to around unity in the zone of oil formation, as a result of thermal degradation and the introduction of new alkanes, which dilutes the original odd-even predominance.  3, record 11, English, - carbon%20preference%20index
