Growth and survival was monitored in full-sib diploid and triploid coho salmon families held at elevated temperature and accelerated photoperiod to induce them to smolt as underyearlings. At tagging, the diploids were significantly heavier than the triploids.

Morphological changes during parr-smolt transformation are generally less apparent in hatchery-reared than wild salmonids. The aim of the present study was to investigate possible differences between wild and hatchery-reared brown trout in regard to physiological character- istics during smoltification.

Smolt Transformation: Evolution, Behavior, and Physiology
Journal of the Fisheries Research Board of Canada, 1976Literature concerned with the appearance of smolts (silvery color, streamlined body form), their physiology (salinity relationships, endocrinology), and their behavior (territorial and schooling) is discussed in relation to key steps that may have been taken in the evolution of the parr–smolt transformation and seagoing behavior.

Comparative Biochemistry and Physiology Part A: Physiology, 1990
Abstract 1. 1. Branchial ionic transport capabilities were studied in smolt and post-smolt Atlantic salmon. We used the perfused isolated head technique to make instant measurements of transbranchial Na+ exchange during direct transfer to sea water. 2. 2.

Smolt Physiology and Endocrinology
2012The parr–smolt transformation of anadromous salmonids is a suite of behavioral, morphological, and physiological changes that are preparatory for downstream migration and seawater entry. The timing of smolt development varies among species, occurring soon after hatching in pink and chum salmon and after one to several years in Atlantic salmon.

Migration of Atlantic salmon (Salmo salar) smolts and post-smolts from a Scottish east coast river
2021The near-shore migratory behaviour of Atlantic salmon (Salmo salar, Linnaeus 1758) migrating to sea for the first time is poorly understood. This study aims to assess whether salmon smolt survival is consistent along the River Dee in Aberdeenshire, through Aberdeen harbour and early in their marine migration out to ten kilometres from shore.

Atlantic salmon which had been released as fry in tributaries of the Connecticut River (Northeastern USA) were captured during the migratory period (9 May to 6 June) 1 to 2 years later. Migrants (smolts) were captured above a dam on the main-stem; non-migrants (parr) were captured in two tributaries. Migrants were significantly larger than non-migrants

To examine the combined effects of photoperiod and body size on off-season parr–smolt transformation and post-smolt growth, groups of small and large graded potential Atlantic salmon smolts (initial size 10 and 23 g) were raised under four different photoperiods between 26 July and 14 November.

Abstract The timing of smoltification appears to be important for survival and homing in Atlantic salmon. For smolt produced as part of population enhancement strategies, it is important to produce smolts that smoltify at the same time as the wild smolts in the area. Further, both transportation and releasing methods induce stress in smolts which can
