  abstract = {{A}s condition is a key variable in population dynamics (especially for survival, growth and reproduction), the use of well-defined and accurate fish condition indices is capital. {I}n particular, condition indices (morphometric, bioenergetic and biochemical) have never been compared and validated for the {E}uropean anchovy {E}ngraulis encrasicolus, the {E}uropean pilchard {S}ardina pilchardus and the {E}uropean sprat {S}prattus sprattus. {T}he accuracy of two indirect methods, the morphometric relative condition index {K}-n, and the bioenergetics index determined with the {D}istell {F}ish {F}atmeter was investigated by comparing with a direct measure of relative lipid content carried out with a thin layer chromatography-flame ionization detector. {E}stimations from the fatmeter correlated quite well with the relative lipid contents of all species, regardless of the reproductive period ({R}-2 = 0.69 for anchovy, {R}-2 = 0.75 for sprat and {R}-2 = 0.48 for sardine). {K}-n, correlated more poorly with relative lipid content ({R}-2 = 022 for anchovy and {R}-2 = 0.41 for sardine, ns for sprat), especially during the reproductive period, pointing out the difficulty for such an index to precisely reflect changes in fat allocation. {D}uring the reproductive period, changes in {K}-n, could reflect other processes, such as changes in protein content. {T}herefore, these different types of commonly used indices do not reflect exactly the same type of energy stores. {T}he high repeatability of the fatmeter was brought to light, so that only one measurement on each fish side may be necessary to evaluate the relative lipid content of a small pelagic fish. {F}inally, fatmeter measurements were not affected by freezing storage up to one month for anchovy ({R}-2 = 0.66) and sardine ({R}-2 = 0.90), making it possible to use frozen samples of both commercial and scientific survey. {I}n contrast, the freezing storage for sprat should be avoided. {B}ased on this study, the {F}atmeter appears to be a suitable indirect method to assess condition and fat content of sardine and anchovy on a large number of individuals.},
