Genetic structure of pike (Esox lucius) reveals a complex and previously unrecognized colonization history of Ireland
AIM We investigated genetic variation of Irish pike populations and their relationship with European outgroups, in order to elucidate the origin of this species to the island, which is largely assumed to have occurred as a human-mediated introduction over the past few hundred years. We aimed thereby to provide new insights into population structure to improve fisheries and biodiversity manageme...
متن کاملresponses to ultraviolet radiation in larval pike , Esox lucius , of two origins and ages
Ultraviolet radiation (UVR)-induced mortality and behavioural disorder were studied in larval northern pike of two origins and ages. Newly hatched larvae of two differently coloured populations and six-day-old larvae of one population were exposed to four fluence rates of UVR, resulting in total doses from 11.5 to 63 kJ m–2, and monitored for mortality and behaviour. The rate of mortality and t...
متن کاملReduction of cannibalism in pike (Esox lucius) fry by isolation of full-sib families.
After 50 days of pond culture fewer pike fingerlings (20 to 33 p. 100) were recovered from the mixing of two full-sib families than from isolated families. Growth and survival were influenced by the family effect. Environmental parameters, such as depth and extent of the banks, may also affect growth and survival. Our results indicated that isolating full-sib families and using small, shallow p...
متن کاملImmunological and Ultrastructural Characterization of True Histiocytic Lymphoma in the Northern Pike, Esox lucius L.1
An epidemic of a malignant neoplasm occurs in northern pike, /„vo.v lucius L., from the Aland Islands of Finland. The neoplasm is morpho logically similar to other pike hernie tumors reported in other areas of the world. Pike normal tissues showed evolutionary conservation with the mammalian intermediate filament proteins cytokeratin, desinili, vimentin, neurofilament protein, and glial fibri...
متن کاملImmunological and ultrastructural characterization of true histiocytic lymphoma in the northern pike, Esox lucius L.
An epidemic of a malignant neoplasm occurs in northern pike, Esox lucius L., from the Aland Islands of Finland. The neoplasm is morphologically similar to other pike hemic tumors reported in other areas of the world. Pike normal tissues showed evolutionary conservation with the mammalian intermediate filament proteins cytokeratin, desmin, vimentin, neurofilament protein, and glial fibrillary ac...
