FEC cells were cultured in Dulbeccos Modified Eagles Medium (DMEM) supplemented with antibiotics, fetal bovine serum (FBS), sea perch serum (SPS), and basic fibroblast growth factor (bFGF). The cells were small and round, and grew actively and stably in culture. The effect of temperature, FBS concentration and bFGF on FEC cell growth was examined. Cells grew well between 24 and 30°C, but had a reduced growth rate below 18°C. The growth rate of FEC cells in medium containing 15% FBS was higher than that in medium containing 7.5% FBS. Addition of bFGF to the medium also significantly increased the growth rate. Chromosome analysis revealed that FEC cells have a normal diploid karyotype with 2n = 48. High survival rate was obtained after cryopreservation of cell cultures. The susceptibility of the cell line to piscine viruses was examined. Two viruses tested were shown to induce CPE (cytopathic effect) on FEC cells. FEC cell culture infected with fish iridovirus was further elucidated by electron microscopy. Many virus particles were found in the cytoplasm of the virus-infected FEC cells. These results indicated that the FEC cell line could be potentially used to isolate and study fish viruses.
