...Jan-Dag Pohlmann; Bernd Pelster; Klaus Wysujack; Lasse Marohn; Marko Freese; Constantin Lindemann; Reinhold Hanel ABSTRACT Many aspects of the typically 5000–10,000 km spawning migration of the European eel ( Anguilla anguilla ) remain unknown. As part of this migration, eels undertake extensive...

.... In preparations from the European eel ( Anguilla anguilla ), a decrease in stimulation frequency from 40 to 15 beats min −1 , which replicates hypoxic bradycardia in vivo , vastly improved cardiac performance during hypoxia in vitro . As eels display dramatic shifts in extracellular HCO 3 − /CO 2 , we further...

...Vincent van Ginneken; Erik Antonissen; Ulrike K. Müller; Ronald Booms; Ep Eding; Johan Verreth; Guido van den Thillart SUMMARY One of the mysteries of the animal kingdom is the long-distance migration(5000–6000 km) of the European eel Anguilla anguilla L. from the coasts of Europe to its spawning...

...-transporting epithelium,the intestine of the euryhaline teleost Anguilla anguilla . Eel intestinal epithelium, when symmetrically bathed with Ringer solution,develops a net Cl - current giving rise to a negative transepithelial potential at the basolateral side of the epithelium. The eel intestinal epithelium...

Using an in vitro working heart preparation, cardiac performance of small (body mass 96.76±27.49 g...

...Sandra Imbrogno; Maria Carmela Cerra; Bruno Tota SUMMARY Using an isolated working heart preparation we show that angiotensin II(ANG II), at concentrations of 10 -10 –10 -7 mol l -1 , elicits negative chronotropism and inotropism in the freshwater eel Anguilla anguilla . The negative inotropism...

... isoform) and vatB2 (brain isoform) —serve different functions. A localization of the two isoforms was attempted in swimbladder gas gland cells of the European eel Anguilla anguilla by immunohistochemistry. Two antibodies were produced by immunization of rabbits with synthetic peptides. Specificity...

... European eel Anguilla anguilla A fundamental problem for all aquatic organisms is the control of body fluid composition and osmolality, particularly when faced with a variable external environment (e.g. tidal changes in estuaries or during migration between freshwater and seawater). Despite...

...Jean-H. Lignot; Christopher P. Cutler; Neil Hazon; Gordon Cramb SUMMARY The expression of a putative water channel protein, aquaporin 3 (AQP-3),has been localised within branchial and intestinal tissues from the `silver'life stage of the European eel Anguilla anguilla , using a specific polyclonal...

...E. Sötz; H. Niederstätter; B. Pelster SUMMARY Gas gland cells of the European eel ( Anguilla anguilla ) were cultured on collagen-coated coverslips, and intracellular pH was measured using the pH-sensitive fluorescent probe 2′,7′-bis-(2-carboxypropyl)-5-(6)-carboxyfluorescein (BCPCF...

...Caroline Prem; Bernd Pelster SUMMARY A cell culture system has been developed in which swimbladder gas gland cells from the European eel ( Anguilla anguilla ) were cultured on a permeable support. Cells seeded on Anodisc 13 (Whatman) or Costar Transwell 13 mm membranes form a confluent cell layer...

... not stimulate the fish in any way. The experiments were performed on juvenile eels Anguilla anguilla L. caught as glass-eels during the winters of 1995/96 and 1996/97 off the Portuguese coast and kept for 3 months at an eel farm in the Netherlands. They were reared to the elver stage in a 301 aquarium...

... the body. We report the first results on the mechanical properties of the red and white muscles of an anguilliform swimmer, Anguilla anguilla . Small preparations (0.147–1.335mg dry mass) were dissected from positions at fractions of 0.2, 0.4, 0.6 and 0.8 of total body length ( BL ). We determined the time...

We observe two major kinematic differences. First, the slope of wave frequency against swimming speed is significantly...
