Abstract

Climate change has various effects on the global food supply and the  environment as a whole. Similarly, the production of fish like Rainbow Trout is affected by variation in the atmospheric temperature higher than 21oC, leading to fluctuations in yield. Therefore, this study sought to investigate the impact of average atmospheric temperature on Rainbow Trout production in South Africa using time series data spanning from 2000 to 2022. The unit root test, Johannsen cointegration test, and the Vector Error Correction model were employed to analyse the data. The results show that the change in average atmospheric temperature affects the production of Rainbow Trout. The correlation between average temperature and Rainbow Trout production is positive in the short-run and long-run. I Prolonged exposure to high temperature may lead to fish stress, migration and increased susceptibility to diseases which ultimately affects the economic viability of the sector in both the short-run and the long-run. In addition, the overall change in the atmospheric temperature has a negative effect on the production of the fish highlighting the need for climate change intervention to sustain fish production. The study recommends implementing strategies that reduce the impact of temperature changes on fish production to support both economic growth and food security.
