The common rudd is a bentho-pelagic freshwater fish, widely spread in Europe and middle Asia, around the basins of the North, Baltic, Black, Caspian and Aral seas.
Coldwater fish, in the context of aquariums, refers to fish species that do not require a heater to remain within tolerable temperatures in a typical indoor aquarium. Some examples are koi, goldfish, weather loaches, hillstream loaches, many species of barbs, sunfish of the family Centrarchidae, many Central American cichlids, and a variety of other species. Some, but not all, of these species are capable of surviving in very low temperatures, including ponds, lakes, or rivers that freeze over winter.
Shiner is a common name used in North America for any of several kinds of small, usually silvery fish, in particular a number of cyprinids, but also e.g. the shiner perch.
The golden shiner is a cyprinid fish native to eastern North America. It is the sole member of its genus. Much used as a bait fish, it is probably the most widely pond-cultured fish in the United States. It can be found in Quebec, and its French name is "Mené jaune" or "Chatte de l'Est".
Pharyngeal teeth are teeth in the pharyngeal arch of the throat of cyprinids, suckers, and a number of other fish species otherwise lacking teeth.
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows. Members of this subfamily are known as European minnows or the Old World (OW) clade of minnows. As the name suggests, most members of this family are found in Eurasia, aside from the golden shiner, which is found in eastern North America.
San Tomas Aquinas Creek, known locally as San Tomas Aquino Creek, is a 16.5-mile-long (26.6 km) stream that heads on El Sereno mountain in El Sereno Open Space Preserve in Saratoga, California in Santa Clara County, California, United States. It flows north through the cities of Saratoga, Monte Sereno, Los Gatos, Campbell, Santa Clara and San Jose before its confluence with the Guadalupe Slough in south San Francisco Bay.
Gyrodactylus gondae is a species of monogenean ectoparasites. It was found in Pomatoschistus minutus and Pomatoschistus lozanoi in European coastal waters.
Gyrodactylus flavescensis is a species of monogenean ectoparasites. It was found in Gobiusculus flavescens in European coastal waters.
Gyrodactylus is a genus of parasitic flatworms in the family Gyrodactylidae.
Strophitus undulatus is a species of mussel in the Unionidae, the river mussels. It is native to eastern Canada and the eastern United States. Its common names include creeper, squawfoot, sloughfoot, and strange floater.
Time-place learning (TPL) is the process by which animals link events with both the location and time of occurrence. It enables them to decide which locations to visit or to avoid based on previous experience and knowledge of the current time of day. TPL presumably allows animals to maximize their chances of finding resources and avoiding predators, increasing survival chances. TPL requires spatial memory and a sense of time. The latter may be based on external time-cues (Zeitgebers), or internally generated circadian rhythms. TPL may fundamentally underlie episodic memory.
The Leuciscidae, commonly known as true minnows, are a large family of the freshwater fish order Cypriniformes.
