Ionoregulation in fishes is essential for survival and success, and osmoregulatory failure is often observed as a precursor to death. The two main climate change factors that are considered in this chapter are: (i)temperature; and (ii) Carbon dioxide-induced acidification. Also presented in this chapter are reviews of the basic mechanisms of ion regulation in marine and freshwater fishes, acid-base regulation, and their links. Studies on the predicted impacts of higher temperatures and aquatic hypercapnia on ion regulation in fishes were reviewed. In the final part of the chapter the side effects of acid-base regulation on otolith growth and GABAA (γ-aminobutyric acid, type A) receptor-associated behavioural changes were discussed. The chapter ends with some future directions in climate-change-associated research into ion regulation in fishes. Although there is consensus that these changes are occurring; predicting long-term impacts on fish populations is still a work in progress.","PeriodicalId":291772,"journal":{"name":"Climate change and non-infectious fish disorders","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123315008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two effects were highlighted namely the altered meristic counts which is the variation in the number of the species-specific countable structures partly heritable and partly dependent on a range of environmental factors during development, affecting developmental rates (i.e. fin spines and rays, gill rakers, lateral line scales and branchiostegal rays). This category also includes fluctuant asymmetry that is the random deviation of a character from perfect bilateral symmetry. The second is deformations (i.e. alteration in shape of previously normally formed elements) - including malformations (primary structural defects resulting from a localized error of morphogenesis), syndromes (sets of abnormalities occurring together) and developmental abnormalities connected to the toxic effects of teratogens in the environment.","PeriodicalId":291772,"journal":{"name":"Climate change and non-infectious fish disorders","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131186685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
