The total mortality rate estimated from the lengths in the scientific surveys, the number of fishing days of a fleet per season, the percentage of immature individuals as well as the amount of gear per fishing area are indicators of fishing pressure on a population. For example, a mean total mortality rate estimated during a period when fishing would not have had an impact on the health of the population can serve as a target reference point. Recommendations aimed at reducing the level of withdrawal can then be issued when this target reference is exceeded. 2, record 1, English, - fishing%20pressure

Le taux de mortalité totale moyen estimé à partir des longueurs dans les relevés scientifiques, le nombre de jours de pêche d’une flotte par saison, le pourcentage d’individus immatures ainsi que le nombre annuel d’engins par zone de pêche sont des indicateurs pertinents de la pression de pêche sur une population. Certains peuvent servir au développement de points de référence. Par exemple, un taux de mortalité totale moyen estimé au cours d’une période où la pêche n’ aurait pas eu d’impact sur la santé de la population peut servir de point de référence cible. Des recommandations qui visent la diminution du niveau de prélèvement peuvent alors être émises lorsque ce taux de référence cible est dépassé. 2, record 1, French, - pression%20de%20p%C3%AAche

Mortality is a key component to understanding population dynamics of fish species. Total mortality is often estimated from the sequential decline observed in cohorts of fish. ... catch curve [methods are] used to analyze this decline ... All catch curves have three regions of interest: an ascending left limb, a domed middle portion, and a descending right limb ... The ascending left limb represents age-classes of fish that are not yet fully vulnerable to the gear used in fishery. Fish in these age-classes are said to have "not fully recruited to the fishery." The catches of fish in these age-classes are not useful for estimating the total mortality rate. 4, record 5, English, - ascending%20left%20limb

Le membre gauche ascendant et le dôme de la courbe de capture représentent des classes d’âge incomplètement capturées par l'engin d’échantillonnage : c'est-à-dire capturées moins fréquemment, par rapport à leur abondance, que le sont les poissons plus âgés. Cela peut provenir du fait que les jeunes poissons sont davantage concentrés dans une autre partie de la masse d’eau que celle surtout pêchée, ou qu'ils sont moins enclins à mordre aux appâts ou à pénétrer dans les filets. Toutes choses étant égales, le taux de mortalité totale ira en augmentant pendant cette période de recrutement. Cependant, il est impossible de rien trouver de défini sur le taux réel de mortalité durant les années couvertes par le membre gauche et le dôme de la courbe, tout simplement parce que la population n’ est pas échantillonnée au hasard [...] 1, record 5, French, - membre%20gauche%20ascendant
