Small-bodied wrasse species are important for structuring coastal marine ecosystems but are also increasingly harvested as parasite cleaners on farmed salmon. Identifying management regulations that will support long-term sustainability of wrasse fisheries is challenging, because there is still limited knowledge about the impacts of fisheries on the demography of these intermediate predators in their natural environments. To this end, we studied individual growth histories of goldsinny wrasse (Ctenolabrus rupestris) at a fine spatial scale across replicated marine protected areas (MPAs) and areas open to commercial harvesting on the Norwegian coast. The MPAs were established 1–7 years prior to our sampling. We detected significant fine-scale spatial variation in wrasse asymptotic body size, but found no consistent difference between MPAs and fished areas. Male wrasses reached larger asymptotic body sizes than females, whereas fyke nets captured individuals with larger asymptotic body sizes compared with baited traps. These are the two commonly used gear types in wrasse fisheries. An extended use of baited traps, along with slot-size limits, could therefore aid in protecting large-growing phenotypes such as nest-guarding males.

Larval life history, transmission strategies, and the evolution of intermediate host exploitation by complex life-cycle parasites
Benesh, Daniel (University of Jyväskylä, 2007)Complex life-cycle parasites use their intermediate hosts both as an energy source and as a vessel for transmission to the next host in the life cycle. Parasites that grow rapidly to a large size may have high fitness (e.g. ... -
When phenotypes fail to illuminate underlying genetic processes in fish and fisheries science
Kuparinen, Anna; Hutchings, Jeffrey A. (Oxford University Press, 2019)Advances in genetic and genomic technologies have become widely available and have potential to provide novel insights into fish biology and fisheries science. In the present overview, we explore cases for which genomic ... -
Maternally‐transferred thyroid hormones and life‐history variation in birds
Hsu, Bin‐Yan; Pakanen, Veli‐Matti; Boner, Winnie; Doligez, Blandine; Eeva, Tapio; Groothuis, Ton G. G.; Korpimäki, Erkki; Laaksonen, Toni; Lelono, Asmoro; Monaghan, Pat; Sarraude, Tom; Thomson, Robert L.; Tolvanen, Jere; Tschirren, Barbara; Vásquez, Rodrigo A.; Ruuskanen, Suvi (Wiley-Blackwell, 2022)1. In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early-phase ... -
Evolution of signal diversity : predator-prey interactions and the maintenance of warning colour polymorphism in the wood tiger moth Arctia plantaginis
Rönkä, Katja (University of Jyväskylä, 2017)Aposematic organisms avoid predation by advertising defences with warning signals. The theory of aposematism predicts warning signal uniformity, yet variation in warning coloration is widespread. The chemically defended ... -
Genetic colour variation visible for predators and conspecifics is concealed from humans in a polymorphic moth
Nokelainen, Ossi; Galarza, Juan A.; Kirvesoja, Jimi; Suisto, Kaisa; Mappes, Johanna (Wiley-Blackwell, 2022)The definition of colour polymorphism is intuitive: genetic variants express discretely coloured phenotypes. This classification is, however, elusive as humans form subjective categories or ignore differences that cannot ...
