Experiments were performed in vitro specifically to elucidate the underlying mechanism(s) of the attenuated adrenergic responses of eel (Anguilla rostrata) erythrocytes. This was achieved by comparing beta-adrenoceptor numbers and affinities in addition to (i) Na+/H+ exchange activity, (ii) cell swelling and (iii) cyclic AMP formation mediated by catecholamines in eel and trout (Oncorhynchus my...

1. Internal as well as external factors affecting water ingestion in the eel were analysed using oesophagus-cannulated eels. 2. Acute withdrawal of the blood induced an immediate drinking response in the freshwater eel, whereas infusion of a large amount of hypertonic saline interrupted the copious drinking observed in the seawater eel. 3. The freshwater eel responded to slow infusion of hypert...

Dioxins, furans and dioxin-like polychlorinated biphenyls (PCBs) were analysed in muscle tissue from yellow phased European eel (Anguilla anguilla) from 38 sites in Belgium. Dioxin concentrations in eel vary considerably between sampling locations, indicating that yellow eel is a good indicator of local pollution levels. Measured levels of dioxin-like PCBs are much higher than those of the diox...

Management of the eel fisheries of the River Shannon, Ireland’s largest river system, has involved van ous stock enhancement measures since 1959. Declining natural recruitmenr levels have limited the effecriveness of stocking programmes for nearly two decades. Observations on declining yellow eel stocks in several major lakes have been supported by the results of studies undertaken annually on ...

European eel (Anguilla anguilla (L.)) stocks are in decline in most of their geographical distribution and their status is considered below safe biological limits. Recently, there is an increasing awareness that spawner quality might be an essential element in the decline of the species since pollution by bioaccumulating chemical substances may have a large impact on the reproduction success of...

To determine if vascular smooth muscle from teleost and agnathan fishes expresses receptors for signaling agents that are important in vascular tension in other vertebrates, we exposed rings of aortic vascular smooth muscle from the eel (Anguilla rostrata), the hagfish (Myxine glutinosa), and the lamprey (Petromyzon marinus) to a suite of putative agonists, including: acetylcholine, endothelin,...

Euonymus europaeus lectin (EEL) is a carbohydrate-binding protein derived from the fruit of the European spindle tree. EEL was first identified for its erythrocyte agglutinating properties and specificity for B and H blood groups. However, a detailed molecular picture of the structural basis of carbohydrate recognition by EEL remains to be developed. In this study, we performed fluorescence tit...

We report here the complete genome sequence of a virus isolated from a diseased marbled eel (Anguilla marmorata) in Taiwan. The virus has been characterized as being related to Japanese eel endothelial cell-infecting virus (JEECV), with a large T-antigen-like protein. The sequence of the marbled eel virus displays low homology to the JEECV.
