Nighttime surveys on concentrations of prespawning herring [produces] real-time estimates of total fish abundance using computer interfaced echosouding equipment. [A] mid-water rope trawl [was] used(10 m tall X 15 m wide opening; 1 cm codend mesh). Analyses of trawl biological samples provide stock indices such as age composition, survival rates, and recruitment.  2, fiche 1, Anglais, - midwater%20rope%20trawl

Past assessments of western Atlantic bluefin tuna... have reduced the number of parameters by assuming pre-specified values for the ratios of the fishing mortality rates on adjacent age groups. More recent bluefin tuna assessments have estimated terminal fishing mortality rates(F) on each age with a constraint that restricts change from one year to the next.... The use of pre-specified ratios for F created strong retrospective biases and may have led to overly optimistic projections. Constraining annual changes in the terminal-year F appeared to mute retrospective patterns and resulted in abundance projections less prone to spurious initial leaps.  1, fiche 2, Anglais, - terminal%2Dyear%20fishing%20mortality%20rate

The population status of Walleye of Tathlina Lake appears to have improved between 2001 and 2007. The mean size (length and weight) of Walleye and age of Walleye has increased, while the increase in catch-per-unit effort of and proportion of Walleye in the total catch suggests an increase in Walleye biomass in the lake. The presence of the strong 1997 year class that reached sexual maturity in 2003 was left to spawn multiple times without considerable harvest has likely helped improve the status of the population.  3, fiche 3, Anglais, - population%20status

Recent declines in abundance of skates... have heightened the need for validated age and growth estimates... skate vertebral centra collected seasonally... were sectioned using a mass processing method, then used to reconstruct growth in each species.... Total counts were obtained by summing visible and estimated band counts. Growth curves were then fitted to all length-at-age data including sections deemed unreadable near the focus. The location of the birth band(BB) in each species was confirmed by comparing suspected birth band radius(BR) measurements with [vertebral radius(VR) ] measurements of available late-term embryos... and/or early young-of-the-year fish... Regressions between VR and [total length] for each species, along with published hatch lengths, were also used to verify the location of the BB along the corpus calcareum of each section...  6, fiche 7, Anglais, - birth%20band
