LuleĆ„ Lappmark [2], 28/07/1732, ¶901:
I visited LAXHOLMEN, where they were still catching salmon – barbed salmon among them. I asked whether barbed salmon were a distinct species or merely differed in age. Both were denied. They showed me quite small salmon which, in proportion, had barbs just as big as the largest, so Bonge was wrong in that respect in his dissertation on salmon.11 I asked whether barbed salmon had roe or milt. They replied that it was always milt, whereas the unbarbed fish always have roe not milt. I had 7 barbed salmon opened and all had milt whereas 4 non-barbed salmon all had roe.
