Abstract
1. The effects on growth of supplementing the medium with (n-3) and (n-6) polyunsaturated fatty acids (PUFA) were investigated in Atlantic salmon (AS) and turbot (TF) cell lines. 2. Neither cell line grew in the absence of serum, and addition of increasing percentages of serum resulted in graded increases in cell growth in both cell lines. 3. The growth of AS cells was stimulated by supplementing the medium with both (n-6)PUFA and (n-3)PUFA at 5–25 μM, especially 18:3(n-3) and 20:5(n-3). 4. Intermediate concentrations (15–20 μM) of 18:2(n-6) and 18:3(n-3) increased cell growth in TF cells, although only after 8 days in culture. 5. In contrast, both (n-3) and (n-6)PUFA at 25 μM tended to inhibit the growth of TF cells, and in longer incubations caused cell death. 6. The inhibition of TF cell growth rate and, in particular, the cell death induced by 25 μM PUFA could be abolished by the addition of vitamin E to the medium.
