Abstract:	Expression of somatolactin (SL) mRNA was quantified during smoltification at 2 week intervals during January and February and weekly during March, April and May 2004 in a line-bred ranching stock of Atlantic salmon Salmo salar . Gene expression of SL (and a splice variant termed SL₁₈₀) was lower in fish sampled in the later weeks of smoltification than in those at the beginning, a pattern opposite to that of gill Na⁺ K⁺-ATPase activity.

Keywords:	alternatively spliced anadromous fish pituitary salmonid smoltification
