Aquaculture plays a key role in provision of food security and livelihoods of millions of people for their social, economic and nutritional benefits. Yet, climate change has been identified a major threat to its sustainability since fish production is highly influenced by environmental factors particularly temperature. With the predictable rise of seawater temperature, marine fish are struggled to adapt in warmer temperature and acidified seawater. Unlike other marine organisms, little attention has been given to understand the impact of elevated temperature on the development of marine fish larvae. Marine fish larvae in particular are very vulnerable during the first stages of development and have strict requirements for biotic and abiotic conditions to survive, develop and grow appropriately. This paper reviews scientific evidences on tolerance of marine fish larvae on elevated temperature towards growth and behaviour and other aspects. It makes serious attempt to summarize the relevant records published on specific research questions to improve understanding of the diverse evidences, and to be able to identify gaps in knowledge. This has helped in articulating the present state of research and defining topics for future studies on the elevated temperature effects on marine fish larvae. From the analysis of published data it is obvious that the impacts of elevated temperature on marine fish larvae give negative impacts on aquaculture industry, thus the review helps in providing knowledge and awareness which could help in mitigate the impact of elevated temperature on marine fish larvae.
