For at undersøge, hvor mange unglaks der ender som skarvføde, blev der over to sæsoner mærket og udsat fl ere end 120.000 1-års laks i Skjern Å. Herefter blev der indsamlet 8.000 gylp i skarvernes ynglekolonier i Ringkøbing Fjord. I gylpene, der består af ufordøjelige føderester, blev der fundet 42 mærker, svarende til at skarverne i de to sæsoner ...

Abstract Regional habitat and fisheries management planning requires estimates of the capacity of watersheds to produce salmonids. To predict the average abundance of smolts of coho salmon Oncorhynchus kisutch produced by streams and rivers, we related estimates of smolt abundance to habitat features derived from maps and discharge records.

[Unit activities of the salmon Salmo salar preoptic nucleus in Parr, Parr-Smolt and Smolt stadia].
Comptes rendus des seances de la Societe de biologie et de ses filiales, 1976The olfactory and gustatory stimulations with NaCl (10(-5)-10(-2) M/1) bring about certain typical modifications of the preoptic cells activity in the case of "Parr" and "Parr smolt". The "on" or "off" or "on and off" effects are very marked. Unlike the "Smolt" stage is accompanied by an important decrease of the preoptic cells activity, sometimes ...

4 The Physiology of Smolting Salmonids
1988Publisher Summary This chapter describes the different aspects of the physiology of smolting salmonids. Many salmonids—the fish of the genera, Oncorhynchus , Salmo , and Salvelinus —are anadromous and undergo a distinct transformation prior to seaward migration. Several morphological and physiological changes occur during smolting.
