	abstract = {Genetic evidence for the selective exploitation by anglers of early running fish was examined in four Iberian Atlantic salmon populations (R. As{\textcent}n, Pas, Nansa, Deva), using protein and mtDNA markers. The populations studied had been exploited exclusively by rod and line over a nearly fixed fishing season (March to July) since 1949. Genetic variation at six protein loci was small and was accounted for by the  MEP-2*  and  MDH-3,4*  polymorphisms, which generally remained stable over time and were in Castle-Hardy-Weinberg equilibrium during the fishing season. However, early running multi-seawinter fish (MSW) generally showed higher frequencies of the common  MEP-2*  (100) allele than did late running, one sea winter (1SW) grilse, which were significantly smaller and tended to escape the fishery. Spawners differed from angled fish in their mtDNA frequencies and consistently showed a lower sea age and a smaller body size. Spawners also smolted at an older age and displayed lower frequencies of the  MEP-2*  (100) allele in three of the four populations studied. These results suggest that anglers in these rivers are selectively exploiting a distinct component of the population, and inadvertently causing a differential mortality of genetic types that is likely to be detrimental.

	abstract = {We have examined the following aspects of the reproductive biology of Atlantic salmon in Iberian rivers: timing of spawning, body size, sex ratio and female fecundity. Egg size and ova colouration were also examined in some populations. Spawning was found to vary considerably, extending from mid November until early February, though the peak of spawning activity typically took place in December. The sex ratio of spawners was usually biased in favour of males, which had on average a younger sea age and a smaller body size than females. Female fecundity varied considerably between individuals, but was found to be proportionately higher in female grilse than in multi-seawinter females. Egg size was also found to differ between age classes, as well as between populations. Compared to more northerly populations, Iberian Atlantic salmon tend to show a greater relative fecundity and a smaller egg size, as predicted by theory for populations inhabiting extreme, marginal habitats governed by r-demographic processes. Such differences in reproductive strategies have probably a genetic basis and are likely to be adaptive.},
