American Eel Subpopulation Characteristics in the Potomac River Drainage, Virginia
The demographic characteristics of American eels (Anguilla rostrata) are believed to vary with latitude and distance inland from the ocean; eels are generally thought to increase in length, age, and the proportion of females in inland and more northerly areas. Understanding this variation is …

Helminth, protozoan and viral infections of the European eel, Anguilla anguilla
The European eel, Anguilla anguilla, is an important catadromous fish that has beenclassified as critically endangered due to severe population decline. The reasons for this arenot fully understood; however, infectious disease undoubtedly makes a contribution. To explorethis further, a total of 509 …

Helminth infections of the European eel Anguilla Anguilla in the United Kingdom
The European eel, Anguilla anguilla, is designated a threatened species and parasites are considered to be one of the contributory factors associated with the species decline. To address the lack of knowledge concerning parasite infections in the UK European eel population, a total of 140 specimens …

American Eel Distibution and Growth in Selected Tributaries of the James River
… Shoe Creek, Virginia, and captured 66 American eels. Eels were weighed (g) and measured (mm) and 61 individuals were implanted with Passive Integrated Transponders (PIT). Size distribution of the tagged eels ranged from 174-775 mm total length. The team returned to Shoe Creek in October of 1999 …

BIO-ECOLOGICAL AND ANATOMICAL ASPECTS OF THE EUROPEAN EEL ANGUILLA ANGUILLA (L. 1758)
… most iconic catadromous species, the European eel Anguilla anguilla (L.) has aroused considerable interest since ancient times, though, to date, many aspects of its life cycle remain relatively unknown. A. anguilla showed a progressively decline since the 1970s. Starting from 2007, has been …

Characterization of the antifreeze peptide system of the Antarctic eel pout, Pachycara brachycephalum
"Pachycara brachycephalum (suborder Zoarcoidei) produces essentially one antifreeze peptide (AFP) that is maintained at high serum levels. The AFP gene family of the species was characterized to elucidate the basis of its particularly homogeneous AFP complement, as compared with other zoarcoids. …

Managing Change: The Sociocultural Implications of the Early English Language (Eel) Policy in South Korea
… implementation of the early English learning (EEL) policy in Korea. The EEL policy, which was implemented in 1997, mandated compulsory English education from grade 3 and up in the public primary schools. This policy stems from the government-led globalization campaign in mid 1990s, which …

Reconstructing the depositional history of the Eel River paleo meltwater channel, northeastern Indiana using sediment provenance techniques
The outwash deposits of the Eel River paleo meltwater channel in DeKalb and Allen Counties, Indiana predominantly originated from the Erie Lobe of the Laurentide Ice Sheet, but do contain some sediment from the Saginaw Lobe. This determination helps clarify the ice dynamics and Last Glacial Maximum …

Characterization of the primary structure of a size-variant antifreeze peptide and the organization and structure of antifreeze peptide genes from the Antarctic eel pout Rhigophila dearborni
The antarctic eel pout Rhigophila dearborni synthesizes three major antifreeze peptides (AFPs) which have been designated RD1, RD2 and RD3, and at least four minor ones. RD1 and RD2 both are 64 residues with a molecular weight (M.W.) of about 7000 Daltons. RD3 however appears to be twice as large …
