Impact of Global Warming on Changing Pattern of Biodiversity and Fish Production in Inland Open Waters

Abstract

Climate change rapidly transforms aquatic ecosystems globally, but the impact of changes in tropical wetlands is not well documented. Sustainable freshwater biodiversity and fisheries management require keeping a record of ongoing and historical stressors such as increased global temperature and fishing pressure. This task is more complicated in tropical water bodies, including India, where publications on the ecosystem change are minimal, and the fishers mostly do subsistence fishing and farming for livelihood and nutrition. Here, we describe the impacts of climate change on fisheries, freshwater ecosystems, aquatic biodiversity, adaptation, and mitigation strategies. The present chapter is divided into two parts; the first part discusses the causes and concerns of global warming, and the second part deals with the impacts of global warming on freshwater fisheries and their biodiversity, suggestive measures, and the development of monitoring methods.
