This is particularly evident for Central Stoneroller
Campostoma anomalum, which frequently visits nests of host Bluehead Chub Nocomis leptocephalus but also spawns separately.
Six species were collected from all six sites sampled: central stoneroller
(Campostoma anomalum), yellow bullhead (Ameiurus natalis), green sunfish (Lepomis cyanellus), bluegill (L.
In this study, a quantitative RT-PCR assay for expression of the VTG gene in the largescale stoneroller
(Campostoma oligolepis) was developed.
Campostoma ornatum (Mexican stoneroller
) and Notropis chihuahua (Chihuahua shiner) inhabit tributary streams of the Rio Grande in the Trans-Pecos region and are considered as state-listed threatened species by the Texas Parks and Wildlife Department (Hubbs et al., 1991; Miller, 1972).
elongatus included: Paddlefish (Polyodon spathula), Spotted Gar (Lepisosteus oculatus), Longnose Gar (Lepisosteus osseus), Gizzard Shad (Dorosoma cepedianum), Threadfin Shad (Dorosoma petenense), Central Stoneroller
(Campostoma anomalum), Blacktail Shiner (Cyprinella venusta), Whitetail Shiner (Cyprinella galacturus), River Carpsucker (Carpiodes carpio), Quillback (Carpiodes cyprinus), Common Carp (Cyprinus carpio), Smallmouth Buffalo (Ictiobus bubalus).
A comparison of the trophic ecology of the crayfishes (Orconectes nais (Faxon) and Orconectes neglectus (Faxon)) and the central stoneroller
minnow (Campostoma anomalum (Rafinesque)): omnivory in a tallgrass prairie stream.
Differential effects of largemouth and smallmouth bass on habitat use by stoneroller
minnows in stream pools.
White and Orth (2014) classified Clinch Dace as a nest associate of Central Stoneroller
(Campostoma anomalum) and Creek Chub (Semotilus atromaculatus) and observed spawning from mid-May to July at a water temperature of approximately 15 C.
Other fish species such as the cyprinids Scarlet Shiner (Lythrurus fasciolaris), Striped Shiner (Luxilus chrysocephalus) and Stoneroller
(Campostoma oligolepis) and the centrarchids Spotted Bass (Micropterus punctulatus) and Redbreast Sunfish (Lepomis auritus) were commonly observed and netted in Limestone Creek.
This region of Texas has the highest percentage of species of vertebrates of conservation concern, and Alamito Creek alone contains three other species of fish (Campostoma ornatum Mexican stoneroller
, Notropis chihuahua Chihuahua shiner; Cyprinodon eximus Conchos pupfish) that are listed as threatened by the state of Texas.
The most common fishes found in pools were bluegill (77%), green sunfish (94%), and rock bass (93%); whereas, in the riffles, central stoneroller
(90%), greenside darter (96%), and northern hog sucker (77%) were most common.
Species occurrence patterns that were negatively correlated with Plains Topminnow population continuance were Central Stoneroller
(Campostoma anomalum (Rafinesque)), Red Shiner (Cyprinella lutrensis (Baird and Girard)), Channel Catfish (Ictalurus punctatus (Rafinesque)), Western Mosquitofish (Gambusia affinis (Baird and Girard)), and Bluegill (Lepomis marrochirus (Rafinesque)) (Table 1).
