Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. Life Though not a formally trained biologist, he worked his way up through the ranks to eventually become the director of the Fish Collection at the Naturhistorisches Museum in Vienna. For the most part, he was not a traveler or explorer like many of the scientists of the time, he remained in Vienna, where he studied and catalogued specimens sent to him from the field. Among those who brought specimens to him were Karl Alexander Hügel, Joseph Russegger and Theodor Kotschy — involving collection activities in Kashmir, the Middle East and northeastern Africa that greatly enriched the Vienna museum. Fish were his specialty and he worked with many of the greatest ichthyologists of his time including Cuvier, Valenciennes, Bonaparte, Müller, and Troschel.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...

Cetina
Cetina () is a river in southern Croatia. It has a length of and its basin covers an area of . From its source, Cetina descends from an elevation of above sea level to the Adriatic Sea. It is the most water-rich river in Dalmatia.Naklada Naprijed, ''The Croatian Adriatic Tourist Guide'', pg. 258, Zagreb (1999), Geography and geology Cetina has its source in the northwestern slopes of Dinara. Rising from a spring at Milasevo near a small village called Cetina, north of Vrlika, it flows to the Adriatic Sea. A large artificial lake begins near Vrlika, the Peruća Lake, which was created by a dam some downstream. Cetina then passes into the lower portion of the Sinj karst field, through the city of Sinj. After that it runs eastward, through the city of Trilj and then back westward around the Mosor mountain, before flowing into the Adriatic in the city of Omiš. Apart from its visible basin, the Cetina also receives a lot of water from the west Bosnian karst field via unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squalius
''Squalius'' is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. '' S. alburnoides'' is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to ''Anaecypris''; the latter mated with ancestral '' S. pyrenaicus''. Present-day ''S. alburnoides'' mates with sympatric congeners of other species.Collares-Pereira, M.J. & Coelho, M.M. (2010)Reconfirming the hybrid origin and generic status of the Iberian cyprinid complex ''Squalius alburnoides''.''Journal of Fish Biology, 76 (3): 707–715.''
