Examples of "studfish"
still occupies all the historical distribution areas and seems to be holding a sustainable population in comparison to the northern
("Fundulus catenatus"), which is seemingly being replaced in these areas. The decrease in some small areas, although not significant, as in Alabama, and the failure to collect additional specimens from previous samples may indicate this species has been extirpated from the Cahaba River system. The southern
is also thought to be replaced in the Tallapoosa River system by the stippled
("Fundulus bifax"). The cause of this decline is the increase in road runoff into these waterways and competition for food and breeding areas.
("Fundulus catenatus") is the largest of the killifish and is native to the southcentral United States.
He was the first to describe the Stippled
("Fundulus bifax") and the bluefin stoneroller ("Campostoma pauciradii").
("Fundulus stellifer") is a ray-finned fish of the family Fundulidae, the tooth carps, that is native to the southeastern United States.
The mean length for adults is . Northern
are sexually dimorphic. Males have horizontal rows of bright orange spots on light blue background and a bright orange tail margin followed by a nearly black band during breeding season. Females are more cryptic colored in shades of beige and olive. Their body shape is elongate and narrow and lacks a lateral line. Northern
have spineless fins and both the anal and dorsal fins are large.
Xenodexia is a genus of poeciliid fish. It contains the single species Xenodexia ctenolepis, the Grijalva
, which is endemic to Guatemala This species grows to a length of TL.
are listed as threatened in the state of Tennessee. Causes for declining numbers range from introduction of aggressive non native fish species like the mosquitofish ("Gambusia spp") to anthropogenic loss of water quality and movement from habitat alteration. Northern
require clear water so control of sediment is integral. Current management practices are to plant riparian zones in order to stabilize the streambanks and control run off from agriculture and construction projects.
Most members of the family are all small. While the giant killifish ("Fundulus grandissimus") and northern
("Fundulus catenatus") can reach in length, most species are under 10 cm in length.
Many of the 40-odd species are commonly known by the highly ambiguous name "killifish" (the general term for egg-laying toothcarps), or the somewhat less ambiguous "topminnow" (a catch-all term for Fundulidae). "
" is a quite unequivocal vernacular name applied to some other "Fundulus" species; it is not usually used to refer to the genus as a whole, however.
has its historical distribution in the upland tributaries of the Alabama River in Alabama (except the Tallapoosa River system); in northern Georgia, in a few of the headwater tributaries of the Chattahoochee River; in the upper Chattahoochee River drainages in northern Alabama and southeastern Tennessee; and the Tennessee and Cumberland River drainages in eastern Tennessee.
("Fundulus bifax") is a small freshwater fish which is endemic to the Tallapoosa River system in Georgia and Alabama, USA; and Sofkahatchee Creek (lower Coosa River system) in Alabama. It belongs to the genus "Fundulus" in the Fundulidae family of killifish and topminnows.
His current research interests include the reproductive ecology of the Telescope Shiner, "Notropis telescopus"; the effects of 11-ketotestosterone in the Scarlet Shiner, "Lythrurus fasciolaris"; the threatened status of the Flame Chub, "Hemitremia flammea"; and the genetic variability of the Stippled
, "Fundulus bifax", a fish endemic to the Tallapoosa drainage system in Alabama.
They are usually smallish; most species reaching a length of at most 4 in (10 cm) when fully grown. However, a few larger species exist, with the giant killifish ("F. grandissimus") and the northern
("F. catenatus") growing to twice the genus' average size.
are egg layers and prefer clear, shallow pools and rocky creeks that have a mixed sand/gravel substrate and constant, sluggish flow. Males do not build nests but they do stake out a territory and defend it. Females lay a clutch of 28 to 245 eggs and give no parental care to their young. Their main diet consists of insects which they skim from the surface of the water but they have also been known to consume snails.
One major management effort to protect the southern
and other killifish and top water minnows, located in Alabama, focuses on the watershed features and current biological and habitat conditions of Hatchet Creek. This management effort was established by the Alabama Department of Environmental Management with the support of the Geological Survey of Alabama. The focus of this effort is to research and develop strategies of future management based on water quality variation, stream hydrology, watershed features, land-use patterns, and biological conditions.
Chironomidae larvae account for 70% of the diet of this darter; Ephemeroptera nymphs account for another 19%, as measured by examining the fish's stomach contents. The species coexists with several other species in its habitat, such as the central stoneroller ("Campostoma anomalum"), southern
("Fundulus stellifer"), and Coosa darter ("Etheostoma coosae"). The species' only real competitor is the Coosa darter, because its mouth size and body length allow it to be a threat for food and space. The main natural predators of the species are from the black basses (genus "Micropterus"). The average standard length of the fish is .
In overall behavior "F. julisia" does not differ greatly from other members of the "Fundulus" genus. It is an opportunistic carnivore that preys upon crustaceans, gastropods (snails and slugs), and insects that are both aquatic and that fall into the substrate. In an examination of gut contents it was found that crustaceans made up 64% of their diet while aquatic insects made up 23% and various other organisms made up the remaining 13%. It competes for this prey with "Fundulus catenatus" (Northern
)and "Gambusia affinis" (Western mosquitofish). This is an interesting relationship because "G. affinis" is one of the leading causes of decline in "F. julisia" due to competition for the same prey. "F. julisia" is preyed upon by bass ("Micropterus" species) and sunfish ("Lepomis" species) within the substrate. Outside the water "F. julisia" is preyed upon by piscivorous birds that spear them with a sharp tipped beak or catch them with ridged edged beaks. During breeding season males are easily spotted due to their bright mating colors, which makes them easier prey. Males have been found to have two different morphs with the primary difference being the marginal and submarginal bands on the caudal and posterior dorsal fin. One morph has a pale yellow submarginal band and the other translucent blue with white and orange submarginal band. All females are far less colorful appearing yellowish and washed out. Even as juveniles males and females can be distinguished from one another due to the males having an iridescent green coloration on their sides.
