During 1876–2017, the mean annual catch of anadromous salmonids (Atlantic salmon and brown trout) was 8.9 tons ( Fig. 19.4) of which Atlantic salmon comprised 95% of the catch in 1983–2017. The salmon population is dominated by grilse and 2-sea-winter fish, and mean individual weight during 1990–2017 was 4.8 kg.

Abstract. A structural analysis of talc ground under dry atmospheric conditions for different grinding times has been made by X-ray diffraction. The SiO 4 tetrahedra are found to remain unchanged in the ground talc samples by analysing the radial distribution function. On the other hand, with an increase of the grinding time a change in oxygen ...
