The 240-h NaCl LC50 for goldfish, Carassius auratus, was estimated as 201.1 (SE 6.7) mmol∙L−1, a concentration well in excess of one recently published value, but consistent with earlier observations on the tolerance of this species for hypersaline conditions. Evidence for operation of several lethal effects that vary in intensity with time, the absence of a well-defined relationship between dose and mortality within an intermediate range of lethal NaCl concentrations, and the strong likelihood of size-related variation in individual sensitivity to NaCl suggest that NaCl is an inappropriate reference toxicant for use in static bioassays involving this species.Key words: NaCl, goldfish, toxicity

An interesting feature of the goldfish liver is the morphology of the hepatic plate, which is always formed by a two-cell layer of hepatocytes. Hepatic plates of the goldfish liver contain an infrequently seen second type of cell, in the centers of plates between two hepatocytes. A TEH study by Yamamoto (1) demonstrated ultrastructural differences between hepatocytes and centrally located cells in hepatic plates; the latter were classified as ductule cells of the biliary system. None of the previous studies clearly showed a three-dimensional organization of the two cell types described. In the present investigation we utilize SEM to elucidate the arrangement of hepatocytes and bile ductular cells in intralobular plates of goldfish liver.Livers from young goldfish (Carassius auratus), about 6-10 cm, fed commercial fish food were used for this study. Hepatic samples were fixed in 4% buffered paraformaldehyde, cut into pieces, fractured, osmicated, CPD, mounted Au-Pd coated, and viewed by SEM at 17-20 kV. Our observations were confined to the ultrastructure of biliary passages within intralobular plates, ductule cells, and hepatocytes.
