Electrophoretic data were analysed from 49 species of freshwater fish, 57 species of marine
fish, and seven anadromous species. For each species, at least 15 individuals had been …

The status and security of fishes in North American deserts have steadily declined in this
century due to man's activities in this naturally fragile region. We address genetic aspects of …

Soon after the introduction of electrophoretic techniques to study the genetic structure of
natural populations of animals and plants came the realization that enzymes differed in their …

Biochemical methods can detect variation at individual genetic loci, making possible the
direct assessment of natural hybridization and introgression between fish populations …

Apparently between 1980 and 1984, Cyprinodon variegatus was introduced into an area of
the Pecos River in Texas, where it hybridized with an endemic species, C. pecosensis …

Threatened and Endangered Fishes of New Mexico by Dr. David L. Propst represents the
first in this new series of technical reports by the Department of Game and Fish. A treatise on …

The literature was reviewed to determine the number of fertile, interspecific fish hybrids
produced naturally and artificially. A total of 130 interspecific, natural crosses resulted in …
