Fishing selection and phenotypic evolution

WebLarge changes are taking place in yield-determining traits of commercially exploited fish, including traits such as size-at-age and age-at-maturation. The cause of these … WebExploitation of fish populations can induce evolutionary responses in life histories. For example, fisheries targeting large individuals are expected to select for early maturation at smaller sizes, leading to reduced fecundity and thus also reduced fisheries yield. These predicted phenotypic shifts have been observed in several fish stocks, but …

WebSelectivity of fishing is traditionally described in terms of body length. Clearly, this is not necessarily the trait determining whether a fish is captured or not, but because of being most easily measurable and strongly correlated with the other traits affecting capture probability (such as girth or mouth size), it has become established as the primary … WebSUMMARY.

WebThe ability to pass changes from one generation to the next is a defining characteristic of evolution. This non-heritable change in the mustard seedling is called phenotypic plasticity, meaning that the organism’s phenotype is flexible and can be influenced by the environment.
