Protein Turnover in Ectotherms and Its Relationships to Energetics

“…More importantly, muscle is the major site of protein accretion in fish as there is little protein degradation (Fauconneau 1985;Houlihan et al 1986;Houlihan and Laurent 1987;Houlihan et al 1988b). The fractional rates of protein synthesis of white muscle are the most responsive to the nutritional state of the fish (Fauconneau et al 1981;Smith 1981;Lied et al 1985); in cod it increases over sevenfold with increasing growth rates and demonstrates the closest relationship with growth rate. These observations provide good reasons for believing that measurementofthe fractional rates of white muscle provides a good indication ofthe growth rates ofthe whole fish (Smith 1981;Fauconneau et al 1990).…”
