International Journal of Aquaculture, 2024, Vol.14, No.4, 195-210 http://www.aquapublisher.com/index.php/ija 204 Figure 4 shows the number of research done per different categories that addressed the issue of climate change and fisheries/aquaculture. Most of the researchers focused on sensors and genetics as a means of climate mitigation and as a digital technological tool for adaptation. Figure 4 Categories addressed by researchers 4 Analysis and Discussion 4.1 Internet of things artificial intelligence and blockchain In their study, Zhang and Gui (2023) described novel digital approaches in the seafood industry, including the intensive use of intelligent aquaculture equipment that could monitor remotely the freshwater quality from inland aquafarms, provide automatic feeds in inland aquafarms (Li et al., 2020), automatically clean the processing facility and automatically fish after adequate growth cycle, all based on technology using telemetry systems, satellite remote sensing, acoustic sensors, and IoT sensors used to monitor ocean health, fish populations, illegal fishing activities, fish behaviour, migrations, noise pollution and water quality amongst others. Nevertheless, the fishery technological sector has not been able to improve substantially as it requires quite a financial investment. Zhang and Gui (2023) also proposed some novel technologies that could be used in the coming years to develop and improve marine aquaculture, as confirmed by Wang et al. (2021). There are some technologies which are mainly being used such as IoT (Internet of Things), big data and cloud computing, the blockchain (Hang et al., 2020) artificial intelligence, data analysis and sharing and finally data encryption, prediction and decision making, (Zhou et al., 2017b). Probst (2019) focused on the use of blockchain, data mining and artificial intelligence that could be problematic for local fishermen. The fishermen might perceive the use of those technologies as a possibility for authorities and large companies to deplete their ocean resources. Furthermore, the author added that the technical equipment needed to maintain blockchains in real time is very costly. The volume of information via satellite systems is very different than on land stations and the cost is very high. According to Cordis (2021) and Kok et al. (2021), with the use of acoustic eco-pulsing technology, fish products could be tracked and farmed where those species find their host forage. The report further stated that this technology, known as fish finder, would be mostly used for commercial rather than recreational fishing, in the
