The global warming is seemed unstoppable as its devastating effects are surfacing across the globe. Not only, is it disrupting human lives but also affecting different things including food production, agriculture, marine life, etc. With global warming increasing at a rapid pace, the fishing industry too is experiencing the heat.
Due to the emission of the greenhouse gases, the whole ecosystem is disrupting. The heating up of the atmosphere is also influencing the oceans as around 70 percent of the heat is absorbed by the oceans. This absorption has further devastating effects. The warming water has less solubility of oxygen. Owing to increasing temperatures of the oceans, they are getting deficit in terms of oxygen, which in turn is influencing the whole marine ecosystem. In a nutshell, the rising temperatures, accompanied by a lower level of dissolved oxygen with increased acidity and changes to the salinity, offering an impact on population numbers, migratory habitats, and distributions.
A newly published study by researchers at the University of British Columbia suggested that there would be $10 billion or 10 percent decline in annual global revenues from fishing by 2050 if climate changes continue unchecked. According to another research from the University of Washington, nearly 500 species of fish deal with particular temperatures. Those species of fishes which are living in hotter parts of the world would tend to be most heavily affected by rising temperatures as they are already living in temperatures nearer to the maximum at which they can cope. This would further affect 35 million people worldwide who are associated with the fishing industry.
A similar piece of research is published in Emirates Journal of Food and Agriculture in which researchers investigated the influence of climate change on the local fishing industry. The research was conducted by the researchers at United Arab Emirates University in Al Ain and Humboldt University of Berlin. The research findings include that there has been a significant fall in the fish catching. Fisheries are a source of income in UAE and also contribute towards food security as well as an alternative to red meat.
The authors pointed out that total fishing catch in the UAE is on the decline and there are several factors such as overfishing, pollution, climatic conditions and competition from imports are responsible for this. The lead author also stated that increasing fishing boats are also putting pressure on the fishes.
A number of pieces of research are pointing out the impact of warming oceans on the marine life. Some of the research works have stated that due to excessive warming, the solubility of oxygen in oceans is on the decline due to which the fishes and other aquatic animals are migrating or perishing. Research works also suggested that sudden change in temperature is also taking toll of marine life as these species cannot adapt to suddenly changing temperature. These rising temperatures are also making these more susceptible to diseases.
