Resumo: | The relationship of the fatty acid composition of the three developmental stages (fingerling, juvenile and adult) of Heterobranchus longifilis (Pisces: Clariidae) and Chrysichthys nigrodigitatus (Pisces: Bagridae) have been evaluated by gas liquid chromatography (Glc) on polyethylene glycol-2-nitroterephthalic ester (PEGNTE). Results indicated that adults of these fishes, accumulated linolenic acid (C18:3w3) above dietary levels atthe fingerling stage which was remarkably depleted in the adult fishes. Its essentiality in their nutrition and metabolism is thus suggested. In the metabolic tumover,.C18:3w3, is utilized to build up the store of eicosapentaenoic acid (C20:5w3), inHeterobranchus longifillis while the store of eicosapentaenoic acis (C20:5w3), arachidonic acid (C20:4w6), anddecosatetraenoic acid (C22:4w6) were improved in Chrysichthys nigrodigitatus. Both catfishes also improved their store of palmitic acid (C16:0, Oleic acid (C18:1w9), and linoleic acid(C18:2w6). Ratios of fatty acids obtained were those which ascribed dominant role to C16 fatty acid, and furtherdeemphasized the role of w6 fatty acids in the metabolism of these catfishes.
