“…Nonetheless, in unfavourable environments, oogonial mitotic division can be stimulated, potentially inducing an increase of fecundity ( e.g ., Prochilodus argenteus Spix & Agassiz 1829) (Thomé et al ., 2012). Thereby, relative fecundity at spawning (egg/g body weight) and potential fecundity do not seem to be affected by thermal breeder exposure [ e.g ., Sea trout ( S. trutta L.), A. lupus , P. flavescens and L. lota ] (Ashton et al ., 2019; Farmer et al ., 2015; Feiner et al ., 2016; Lahnsteiner & Leitner, 2013; Tveiten et al ., 2001; Tveiten & Johnsen, 1999). However, in S. salar , O. bonariensis and river lamprey [ Lampetra fluviatilis (L. 1758)], evidence of depression of relative fecundity has been found (Anderson et al ., 2017a; Cejko et al ., 2016; Elisio et al ., 2012; Pankhurst et al ., 2011).…”
