Tot PLs, total fatty acids in the phospholipid fraction; Tot sat, total saturated fatty acids; Tot mono, total monounsaturated fatty acids; Tot poly,or PUFAs, total polyunsaturated fatty acids; n3, n3 PUFAs; n6, n6 PUFAs; mono,monounsaturates; poly, polyunsaturates; Unsat index, unsaturation index; PC/PE ratio, ratio between phosphatidylcholine and phosphatidylethanolamine.

Specimens were exposed to 50%SW with or without (control) 30 mmol l-1 NH4Cl.

Values are means ± s.e.m. (N=5, except for cholesterol, N=7).
