documented for commercial fishing, particularly in the marine environment, the potential …

Extensive individual variation in spatial behaviour is a common feature among species that
exhibit migratory life cycles. Nowhere is this more evident than in salmonid fishes; individual …

The availability of suitably sized spawning gravels limits salmonid (salmon and trout)
populations in many streams. We compiled published and original size distribution data to …

In this paper we propose an explanation for (a) the predominance of male care in fishes, and
