| Abstract |
Hematological status was examined in rainbow trout,Oncorhynchus mykiss, held for 3-4 weeks under temperature, photoperiod and PO 2 conditions approximating those of their winter, spring and summer habitats. The most striking change observed was in red cell population composition. In 'winter' fish mature cells were predominant; juvenile and developing erythrocytes characterized 'spring' and 'summer' animals. Hemoglobin, hematocrit and both mean erythrocytic volume and hemoglobin were modestly lower in 'spring' and 'summer' than in 'winter' fish. Red cell numbers were not significantly affected. These observations suggest that avoidance of viscosity-based increases in circulatory work cost is more advantageous than elevation of blood O2-carrying capacity. Although hemoglobin isomorph profiles were significantly altered, there is little evidence that such changes are of critical adaptive importance. Given presumed age-based reduction in gas transport effectiveness, the replacement of mature and senescent cells by more metabolically-competent juvenile cells appears to be the pivotal event in hematological response. Leucocyte counts were significantly elevated in 'spring' and 'summer' as compared to 'winter' fish. Lymphocyte/heterophil ratios declined from 8.27 in 'winter' fish to 3.13 in 'summer' trout. Thrombocyte, monocyte, eosinophil and basophil abundances were little changed. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 January 2015.
All research outputs
#20,251,039
of 22,780,165 outputs
Outputs from Fish Physiology and Biochemistry
#601
of 861 outputs
Outputs of similar age
#28,875
of 29,419 outputs
Outputs of similar age from Fish Physiology and Biochemistry
#1
of 1 outputs
Altmetric has tracked 22,780,165 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 861 research outputs from this source. They receive a mean Attention Score of 1.6. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 29,419 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
