IMPACT OF GLOBAL WARMING ON AQUACULTURE IN NORWAY

Abstract

While aquaculture is predicted to play a significant role in addressing future global food demands, climate change is having a complex impact on aquaculture output. Climate change will have an effect on output levels, growth, feeding efficiency, and consequently farm productivity and profitability. The most significant challenges facing aquaculture are current and future climate change, which affects the viability of fish farming in Norway and around the world. Global warming and climate change have resulted in a decline in lake waters, an increase in sea level, changes in streams, and changes in precipitation models, all of which have begun to have a negative influence on all aquatic animals. According to the findings of this study, the yearly maximum temperature was 21.1 °C in July and the lowest was -2.8 °C in January, with the minimum temperature ranging from 13.5 °C in July to -7.5 °C in January. The highest average temperature was 17.4 °C in July, and the lowest was -5.1 °C in January. In terms of precipitation, the greatest was 118 mm in August, while the lowest was 56 mm in March. In terms of rainy days, the highest total was 11 mm in August, while the lowest total was 6 mm in March. In November, the humidity reached 90%, whereas in June, it was 66%. On bright days, the highest daylight hours were recorded in June at 12.1 hours, and the lowest hours were recorded in December at 2.5 hours. In this research, we explicitly investigated how these climate components may affect aquaculture in Norway. As a result, because it affects the stability of fish farming, this significant environmental issue must be addressed. It is critical to shed light on and thoroughly analyse the elements related to climate change in order to avoid the damages that result from them, as well as to identify strategies to adapt to these conditions and limit their effects on production and productivity. Corrective efforts should be implemented to reduce climate change and its consequences on fish output.
