...– actively from the environment, but seawater eels cope with the obligatory influx of SO 4 2– through the gills by excreting excess SO 4 2– via the kidney and in mucus. To collect basic information about the whole-body SO 4 2– budget in teleost fish, we used Japanese eels (Anguilla japonica Temminck...

... tubule marine teleost Anguilla japonica The SO 4 2– content of seawater (SW) is >40-fold higher than the SO 4 2– concentration in the plasma of marine teleosts. Thus, marine teleosts are continuously exposed to a risk of excess SO 4 2– , which enters the gills and the digestive tracts...

...Takaaki Nishi; Gunzo Kawamura; Keisuke Matsumoto SUMMARY Magnetosensitivity of the Japanese eel, Anguilla japonica , was examined by conditioning and electrocardiography. Marine eels, river eels and farmed eels were conditioned to an imposed magnetic field ranging from 12 663 nT to 192 473 nT...
