  abstract = {{L}imited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. {I}n particular, the cost of reproduction is well known to negatively affect energy investment in growth and maintenance. {H}ere, we investigated these trade-offs during contrasting periods of high versus low fish size and body condition (before/after 2008) in the {G}ulf of {L}ions. {F}emale reproductive allocation and performance in anchovy ({E}ngraulis encrasicolus) and sardine ({S}ardina pilchardus) were examined based on morphometric historical data from the 1970s and from 2003 to 2015. {A}dditionally, potential maternal effects on egg quantity and quality were examined in 2014/2015. {A}fter 2008, the gonadosomatic index increased for sardine and remained steady for anchovy, while a strong decline in mean length at first maturity indicated earlier maturation for both species. {R}egarding maternal effects, for both species egg quantity was positively linked to fish size but not to fish lipid reserves, while the egg quality was positively related to lipid reserves. {A}tresia prevalence and intensity were rather low regardless of fish condition and size. {F}inally, estimations of total annual numbers of eggs spawned indicated a sharp decrease for sardine since 2008 but a slight increase for anchovy during the last 5 years. {T}his study revealed a biased allocation towards reproduction in small pelagic fish when confronted with a really low body condition. {T}his highlights that fish can maintain high reproductive investment potentially at the cost of other traits which might explain the present disappearance of old and large individuals in the {G}ulf of {L}ions.},
