dc.description.abstractProstaglandin levels in different tissues and cyclooxygenase (COX-2) gene expression were compared between wild and cultured Senegalese sole (Solea senegalensis) broodstock in which a significantly different fatty acid profile, particularly lower tissue levels of arachidonic acid (ARA, 20:4n-6) and higher levels of eicosapentaenoic acid (EPA, 20:5n-3) in the cultured fish compared to wild had already been described. This is the first report of the COX-2 mRNA expression in Senegalese sole. Cyclooxygenase (COX-2) mRNA expression and prostaglandin (2- and 3-series) levels were determined in tissues from 32 broodstock fish, 16 (8 males and 8 females) from each origin wild and cultured (G1). Transcripts of COX-2 were highly expressed in gills, sperm-duct (s-duct), testis, oviduct and spleen compared to liver, kidney and muscle. Differences in COX-2 transcripts expression were found in response to the origin of the fish and expression was significantly higher in s-duct and gills from wild fish compared to cultured. Wild fish showed significantly higher levels of total 2-series PGs and lower levels of 3-series compared to cultured fish. The significance of the lower COX-2 expression and lower PG 2-series production in some of the tissues of cultured fish was discussed in relation to the previously described differences in fatty acid profile (lower tissue levels of ARA and higher levels of EPA and EPA/ARA ratio in cultured fish) and the reproductive failure to spawn viable eggs from G1 cultured Senegalese sole compared to successful spawning from captive wild broodstock.en_UK
