✦ Synopsis
180 rainbow trouts (Salmo gairdneri RICH .), aged from 1 to 3 years, were examined for fluctuations, caused by age and season, by means of colour index (CI), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) .
CI and MCH behave similarly . Both are increasing until the 2nd year and stay relatively constant thereafter . If the gender is not considered -there are no significant differences in the values of males and femalesthe CI increases from 1,4 in the first year over 1,6 to 1,7 in the age of 3 years, and the MCH increases from 44,4 yy over 52,6 yy, 56,8 yy, 58,1 yy to 55,5 yy .
A seasonal periodicity of both indices could not be indicated on not-matured animals (F 2) which were two summers of age . Only, the january values appeared increased -CI : 2, MCH : 68,3 yyotherwise the CI varies between 1,8 and 1,7 and the MCH between 53,3 yy and 59,1 yy .
The MCHC-values of the age groups examined vary between 24,4% and 27,3% . The values of the yearlings form an exception (19,8%) . These values certainly are inexact and too low because of the small number of individuals checked (3) . * Mit finanzieller Unterstiitzung durch die DFG . Eingegangen am 11 . Oktober 1971 .
