“…Top-down regulation from the government can help to enforce sustainable pest management practices. Salmon aqua culture, especially in Norway, is subject to a range of regulations intended to minimise the ecological impact of the growing industry (Jackson et al 2018, Afewerki et al 2022. Mandates such as louse limits and production caps under Norway's 'Traffic Light System' are directly aimed at reducing parasite spillover into wild salmonid populations (Johnsen et al 2021).…”

As the aquaculture sector continues to expand, there is likely to be a growing need to combat infectious diseases. The desire for rapid and effective results means that any concerns about longer-term effects of disease controls are often sidelined. In particular, the well-documented capacity for parasites and pathogens to evolve treatment resistance must not be ignored in aquaculture. Outbreaks of resistant parasites pose significant threats to the environment, as well as to farm production. If an industry wishes to avoid treatment resistance, there must first be committed research into the evolutionary biology of the parasite species. Such research should be incorporated into the early phases of developing and implementing a treatment strategy—the sooner the risk of resistance is identified, the sooner its impacts on aquaculture can be mitigated. Here I discuss a research framework that can help guide this process. A combination of theoretical (reviewing the literature), empirical (testing for heritable resistance) and modelling (simulating evolutionary dynamics) studies is recommended. Armed with the knowledge from these studies, parasite management strategies can then be optimised at a regional scale (e.g. with refugia or treatment combinations) in ways that minimise the potential for adaptation. The interaction between salmonid aquaculture and parasitic sea lice is an ideal case study for this topic, and the insights gained from this system should be considered across aquaculture industries. Nevertheless, there is no one-size-fits-all solution to treatment resistance. For each system, dedicated research into parasite evolutionary biology—with a research framework as a guide—is required for aquaculture to home in on the most sustainable disease management strategies for the future.

“…Aquaculture production and global fishers increased from 1.5 % to 184.6 % million tons in 2022, according to the United States Food and Agriculture Organization (FAO) ( Halim and Nabi, 2022 ). Many scientific reports are being established on growth, new technology for aquatic species cultivation, harvesting, and technical issues encountered during the process ( Afewerki et al, 2022 ). Shrimp farming has the potential to harm the aquatic environment and coastal areas through habitat destruction, waste disposal, pathogen invasion, and plastic accumulation ( Naylor et al, 2000 ).…”

“…For illustrate, early tiny farms frequently operated in areas with poor water quality and oxygenation, which were aggravated by the farms and offered incentives to relocate farms to more exposed regions. Moving farms to progressively more exposed offshore locations has recently been encouraged in part by decreased salmon lice numbers Afewerki et al (2023).…”

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.
