Última A model for the phenotypic plasticity of North sea herring growth in relation to trophic conditions ArchiMer Shinn, Yunne-jai; Rochet, Marie-joelle. An adaptation of the von Bertalanffy growth model is formulated to describe the phenotypic plasticity of fish somatic growth in relation to trophic conditions. The model is developed for the North sea Downs herring (Clupea harengus). II suggests that annual growth variability during 1974-1990 was mainly due to the combined effects of herring abundance and wind-induced turbulence (coincident with the spring stratification of the water column). Springtime turbulences cause reduced and delayed planktonic blooms preceding the annual foraging period of Downs herring. The negative relation observed between herring abundance and growth is hypothesized to be due to intra-specific competition for trophic resources. Incorporated into the calculation of yield per...

Adaptation is a concept at the heart of the theory of evolution by natural selection. It designates both the process which allows the adjustment of the phenotypic trait of an individual to external environmental conditions and the state resulting from this process. In this context, genetic adaptation represents all of the molecular determinants of adaptation, which means, all of the mechanisms that drives adaptation of species at the molecular level. To study the evolutionary processes during adaptation, we can study the evolution of an experimental population in response to the conditions imposed by the experimenter (environmental, demographic, etc.): this is experimental evolution. When these experiments are coupled with high-throughput sequencing, the...

Fishing is an important source of mortality in harvested populations and therefore may induce adaptive responses. These responses affect life-history traits in particular, which have consequences for stocks’ dynamics, and thus can alter the demographic direct effect of fishing (i.e. the reduction in stock’s biomass). Fishing-induced adaptive changes depend, non-exclusively, on two processes: evolution and phenotypic plasticity. These two components are observed at the phenotypic level because functional genes coding for the traits undergoing adaptive changes have not yet been identified. These two origins are confounded in individual phenotypes, and the impact of adaptive changes in the long run remains therefore unclear: evolutionary changes are expected...
