Results of this study also suggest an apparent increase in the relative abundance of Gambusia affinis
in the Double Mountain Fork after impoundment of Lake Alan Henry.

is widely distributed in eurythermal waters, and G.
Size frequency distributions indicated sampling gear was selective for fish greater than about 25 millimeters length, allowing relatively complete adult size class sampling for all species except Gambusia affinis
(mosquitofish) and Menidia beryllina (inland silverside).
Other taxa that were present in small numbers, so that we cannot be sure if they were systematically moving upstream, include larvae of the giant water bug Abedus herberti (Hemiptera: Belostomatidae), adults of Berosus (Coleoptera: Hydrophilidae), tadpoles of the canyon treefrog Hyla arenicolor (Hylidae), longfin dace Rhinichthys chrysogaster (Cypriniformes: Cyprinidae), and mosquitofish Gambusia affinis
The widely distributed members of the Gambusia affinis
complex are commonly known as mosquitofish because of their reputation as biological control agent for mosquito infestations.
Cyprinella lutrensis, Gambusia affinis
, Pimephales vigilax, Menidia beryllina, and Fundulus notatus were the five most abundant taxa collected, respectively, comprising 79 percent of the total number of fish obtained.
Poecilia reticulata, Gambusia affinis
, Brachyrhaphis rhabdophora), the species and populations evolved the same traits independently and as a response to the same environmental factors such as predation, stream velocity, or population density (Reznick and Endler, 1982; Johnson and Belk, 2001; Reznick et al.

and Poecilia reticulata (Guppy) and some local fishes in different mosquito breeding habitats has been well-demonstrated (5-8).
