- Pertaining to or exhibiting merism.
Westslope cutthroat trout tend to have fewer meristic elements than Yellowstone cutthroat, but the variation in counts within each species and the overlap of counts between subspecies is considerable.
Such changes in meristic characteristics would be expected from a hybridization with hatchery rainbow trout.
In coloration and spotting patterns, and in their meristic characteristics, the Yaqui and Mayo trout resemble the Gila trout, which might suggest they were derived from the same ancestor.
Such modification of meristic characteristics would be expected from a hybrid influence from hatchery rainbow trout, which were continually stocked in the main Kern and its tributaries for more than 90 years.
In the evolution of the South Fork Kern and Golden Trout Creek golden trout, trends in coloration, spotting, and meristic countable traits characteristic of northern Sacramento basin redband trout have been taken to extremes.
Museum specimens of Kern River rainbow trout collected in 1893 and 1904 have the same meristic characteristics as specimens of Little Kern River golden trout collected at the same time.
In the Mexican golden trout, the greatest differentiation from all other rainbow trout species is found in meristic countable characteristics, such as number of scales, fin rays, and pyloric caeca.
Now, though we know very little about the heredity of meristic differences, all that we do know points to the conclusion that the less-divided is dominant to the more-divided, and we are thus justified in supposing that there are factors which can arrest or prevent cell-division.
The violation of meristic law is [Greek: anomia] (iniquity).
And the object of meristic law is not only to secure to every man his rightful share (the share, that is, which he has worked for, produced, or received by gift from a rightful owner), but to enforce the due conditions of possession, as far as law may conveniently reach; for instance, that land shall not be wantonly allowed to run to waste, that streams shall not be poisoned by the persons through whose properties they pass, nor air be rendered unwholesome beyond given limits.
