ciscoes उदाहरण वाक्य

Based on molecular data this is not a natural classification however, as the ciscoes are polyphyletic, comprising two different lineages within the freshwater whitefishes.
Ciscoes are known to exhibit large fluctuations in reproductive success and will produce several years of strong year classes followed by several years of poor reproductive success.
The Colville River used to host a small commercial fishery for Arctic ciscoes, and though the fishery is closed, and nearshore forage fishes like Arctic cod and capelin.
The "'freshwater whitefish "'are fishes of the subfamily Coregoninae, which contains whitefishes ( both freshwater and anadromous ) and ciscoes, and is one of three subfamilies in the salmon family Salmonidae.
The systematics of the group of fishes called " ciscoes " is complicated and scientists now generally believe that the longjaw cisco was not a separate species, but a distinctive population of large-bodied individuals of shortjaw cisco ( " Coregonus zenithicus " ).

The "'ciscoes "'( or " ciscos " ) are salmonid fish of the genus " Coregonus " that differ from other members of the genus in having upper and lower jaws of approximately equal length and high gill raker counts.
The genus was previously subdivided into two subgenera " Coregonus " ( " true whitefishes " ) and " Leucichthys " ( " ciscoes " ), " Coregonus " comprising taxa with sub-terminal mouth and usually a benthic feeding habit, " Leucichthys " those with terminal or supra-terminal mouth and usually a pelagic plankton-feeding habit.
