Development of the swimbladder in the European eel (Anguilla anguilla)
Cell and Tissue Research, 2002The swimbladder of the adult eel, Anguilla anguilla, with its bipolar countercurrent system, the rete mirabile, is a widely used model for swimbladder function, but very little is known about the development of this swimbladder. Our histological studies on the developing swimbladder revealed that during metamorphosis the swimbladder becomes present as ...

Steroid Production in Testicular Tissue of the European Eel*
Endocrinology, 1982Testicular tissue of normal and hCG-stimulated European eels was incubated in vitro with tritiated progesterone or androstenedione as substrates. The following compounds were isolated and identified: 5 beta-androstane-3,17-dione; 17 beta-hydroxy-5 beta-androstan-3-one; androst-4-ene-3,11,17-trione (adrenosterone); 11 beta-hydroxyandrost-4-ene-3,17 ...

The Lady and the Eel: how Aphra Behn introduced Europeans to the "numb eel"
Perspectives in Biology and Medicine, 2012Aphra Behn (1640-1689) has been called the first professional British female writer. Behn probably visited Surinam in the 1660s, but it was not until 1688 that she wrote Oroonoko: or, The Royal Slave , the novel for which she is best remembered. Although overlooked by historians of science, Oroonoko provided a description of the "numb eel," effectively

Coelioscopic Investigation in European Eels (Anguilla anguilla)
Journal of Exotic Pet Medicine, 2014Abstract Coelioscopy is a surgical technique in which small incisions are made into the coelomic cavity through which specific instrumentation is inserted to evaluate the internal structures within. For this reason, coelioscopy must be considered a less-invasive surgical method than traditional abdominal surgery. This study was aimed at evaluating and

Ultrasonography to assist with timing of spawning in European eel
Theriogenology, 2017Ovulation in the European eel can be induced by injection of DHP (17α,20β-dihydroxy-4-pregnen-3-one). The timing of injection is based on the developmental stage of the oocytes. The oocyte stage is determined by invasive biopsy or through external indicators of the oocyte hydration response: body weight index (BWI) and body girth index (BGI).

Genetic evidence against panmixia in the European eel
Nature, 2001The panmixia hypothesis--that all European eel (Anguilla anguilla) migrate to the Sargasso Sea for reproduction and comprise a single, randomly mating population--is widely accepted. If true, then this peculiar life history strategy would directly impact the population genetics of this species, and eels from European and north African rivers should ...

European Eels: Dutch Fisheries, Culture and Eel Migration
2013The Netherlands is largely wetlands, so the country is classic habitat for the European eel (Anguilla anguilla), which was until relatively recently a common fish of the marine/brackish coastal area, found in rivers and wetlands. At high tide, half the country would be flooded were it not for the dikes and other water controls.
