An overview of electronic tags that can be used in fish research is given, including radio and
acoustic transmitters, data storage tags (DST, also termed archival tags), pop-up satellite …

Wild riverine fishes are known to rely on burst swimming to traverse hydraulically
challenging reaches, and yet there has been little investigation as to whether swimming …

Advantages of PIT tags are their small size, longevity, and low cost compared to other tags.
They are often used in fisheries to study movement patterns and survival or to estimate …

Background A laboratory experiment was conducted to assess the potential impacts of
surgically implanted 23 and 32 mm passive integrated transponder (PIT) tags on survival …

Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number
of books have been published on this subject. However, most of these books only cover one …

Fish migrations through riverine systems can be energetically demanding, and the presence
of fishways to facilitate upstream passage can add an additional energetic cost that may …

Recent evidence supports the existence of a downstream autumn-migratory phenotype in
juvenile anadromous brown trout (Salmo trutta), however the precise timing, extent and …

High reproductive performance is the key attribute of male fitness, especially due to the high
reproductive skew among the males of most animal species. Males of long-lived iteroparous …

In polygynandrous mating systems, in which females limit reproductive success, males can
increase their success by investing in courtship. Earlier arrival at the spawning ground …

Background Animal migrations are periodic and relatively predictable events, and their
precise timing is essential to the reproductive success. Despite large scientific effort in …
