Of the 42 species of fish found in Scottish fresh waters, only half have arrived by natural colonisation. Native species include allis shad, brown trout, European eel and river lamprey. Scottish rivers support one of the largest Atlantic salmon resources in Europe, with nearly 400 rivers supporting genetically distinct populations. [10]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
Maerl is a slow-growing coral-like calcareous red algae (it grows only 1 mm per year) and is an important Scottish species. Maerl beds are locations of high biodiversity and are crucial nursery grounds for both young scallops and young fish. Studies show that both scallop dredging and organic waste from fish farms, significantly impact Maerl.
The taxonomic status of the British whitefish populations, including powan, is a matter of debate. Currently the Scottish powan, along with the Welsh gwyniad known from a single lake, and four similar populations in England known as schelly, are generally considered belonging to the widespread Eurasian common whitefish (Coregonus lavaretus).
This is a list of fish found in and around Great Britain, in both fresh water (lakes, rivers, streams and man-made pools) and salt water. This list includes species that are native to Great Britain , as well as those which have been introduced from other countries.
However, the decline in the stocks of whitefish species such as cod and haddock has seen pouting acquire a growing value as a commercial fish, [4] and they are now available both as whole fish from fishmongers and supermarkets and are also used in fish products such as fish fingers and ready meals. Due to their naturally short lifespan and ...
Sturgeon (from Old English styrġa ultimately from Proto-Indo-European *str̥(Hx)yón-[1]) is the common name for the 28 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous , and are descended from other, earlier acipenseriform fish , which date back to the Early Jurassic period, some ...
Ferox trout is a traditional name for large, piscivorous trout, which in Scotland feed largely on Arctic char. It has been argued to be a distinct species, being reproductively isolated from "normal" brown trout ( Salmo trutta ) of the same lakes, particularly in Ireland. [ 1 ]
