Excerpt from The Scottish Naturalist: A Monthly Magazine Devoted to Zoology, With Which Is Incorporated "the Annals of Scottish Natural History"

But when all this is said it does not explain the presence in winter, in small but significant numbers, of Chimera in the neighbourhood of the Norwegian Deep. It is known that in addition to spawning along the continental slope and plateau, 'chimaera spawns to some extent on the coast of Norway in comparatively shallow water. Professor Thompson draws attention to the older accounts of the occurrence of ripe fish and the finding of eggs in this region. To this I may add that Nordgaard1 recorded the taking of newly spawned eggs in April and August in Trondhjem Fjord. From these discoveries we may conclude that the spawning season extends from January or February to August. If this be the case also in the Atlantic then it is evident that the spawners begin their migration in winter. Does this explain the presence of Chimaera towards the end and the beginning of the year off the coast of Norway? If it does then the gonads ought to be found to be ripe or approaching that condition.
