| This thesis was concerned mainly with the genetic diversity and the effective size (Ne) of wild fish stocks of diadromous migratory endangered Atlantic salmon (Salmo salar). For this, four populations were chosen in the northern (Scotland) and southern (France) part of Europe for their differences in their structure and management. This work led to the development of two new models. DemoDivMS predicted genetic diversity of a population whose evolutionary scenario, given by the user, describes variations of Ne during the previous generations. VarEff tries to estimate the effective sizes, sampling time and pasts, based on direct analytical calculations to shorten the time of calculations. |

| This document presents a characterization of the Reunion Island pelagic longline fishery, with a first description of the albacore catches, catch-at-size, and the standardized catch per unit of effort (CPUE) series for the period 1992-2013. The spatial catch and effort analysis revealed the major areas of operation of the fishery, and the identification of the fishery core region closer to the Reunion Island area. The trends in the albacore catch-at-size were analyzed annually, and compared between the seasons and regions of operation of the fishery. The albacore nominal CPUEs were calculated as number of fish per 1000 hooks, and were standardized using Generalized Linear Models (GLMs). Four different modeling approaches were used (including Tweedie,... |
