“Fisheries have not always been viable.” Pauly et al.’s assertion was supported by the realization that the global serial depletion of wild stocks was the cause of this lack of sustainability. Increased fishing technology, geographic expansion, and the exploitation of formerly marginalized species at lower levels of the food chain are the main causes of this trend. In return, aquaculture was frequently thought to either help close the gap between supply and demand or, conversely, to make things worse.
Aquaculture output has increased significantly since the 1970s and is currently one of the aquatic food production industries with the fastest growth rates worldwide. In addition to this industry’s explosive growth, the general reduction in fisheries yields has been exacerbated by rising consumer demand for aquatic products. Captured fisheries and aquaculture produce almost 15% of the world’s animal protein supply annually, which makes them important sources of protein.
Aquaculture: is the farming of aquatic organisms, such as fish, mollusks, crustaceans, and aquatic plants, with certain interventions made during the rearing process to improve yield, like consistent feeding, predator protection, and stocking. More specifically, aquatic creatures grown in brackish or marine conditions are the focus of marine aquaculture, also known as mariculture.
Integrated Coastal Zone Management (ICZM) is the process of managing the coast with an integrated approach, taking into account political and geographical borders as well as all other aspects of the coastal zone, with the goal of achieving sustainability. ICZM is a dynamic, multidisciplinary, iterative method to enhance sustainable management of coastal zones, according to the EU Commission [3]. It includes all phases of gathering data, making decisions, managing the process, planning (in the widest sense), and keeping an eye on how things are being carried out. In order to determine the social goals of a particular coastal area and to take action toward achieving these goals, ICZM uses the cooperation and informed participation of all stakeholders. In the long run, ICZM aims to strike a balance between the goals of the environment, economy, society, culture, and recreation.
Raising fish far from the coast in a setting that is typically hostile and exposed to a range of maritime conditions is known as offshore aquaculture.
Offshore aquaculture is the practice of raising fish far from the coast in an environment that is usually unfriendly and exposed to a variety of maritime conditions.
An array of wind turbines in a single, enclosed space that generates electricity in the open sea is known as an offshore wind farm. Wind turbines are less noticeable offshore than they are on land because of the distance, which reduces both their noise and apparent size. The average wind speed over open water is typically much higher than over land because the surface of water has less roughness than land, especially in deeper areas. As a result, compared to onshore and nearshore locations, the capacity factors are significantly larger.
Food systems account for one-third of worldwide anthropogenic greenhouse gas (GHG) emissions and are highly dependent on energy, especially fossil fuels, for their production (Neff et al., 2011; IRENA & FAO, 2021; Khan and Hanjra, 2009; Namany et al., 2019). Reducing emissions from the food and agriculture sectors is essential to meeting both national and international climate targets (Parker et al., 2018; Clark et al., 2020).
The task at hand is to provide food security while changing the food and energy sectors in a fair and sustainable manner (IRENA & FAO, 2021). One of the most promising ways to combat climate change and enhance the sustainability of the food system is to replace fossil fuels with renewable energy sources (IRENA, 2017).
Both aquaculture, or aquatic farming, and capture fisheries contribute almost equal amounts to global production, although they demand different amounts of energy. The primary source of energy used by capture fisheries is vessel power. In 2011, an estimated 40 billion liters of fuel were utilized worldwide, resulting in 179 million Tonnes of greenhouse gasses (GHG) equal to CO2 (Parker et al., 2018).
We investigate changes in grid source energy and power costs for various industries using simulation. To the best of our knowledge, this is the first study to describe how various segments of the American aquaculture and fisheries industries currently and potentially employ renewable energy. To effectively address the energy use dilemma in seafood, sector- and geography-specific case studies such as this one are necessary, given the diversity of methods, geographies, and other aspects across fisheries and aquaculture.
Since the fishing and aquaculture industries rely heavily on fossil fuels, they must improve their energy efficiency and climate friendliness in order to reach both the national goal of having a net-zero economy by 2050 and the global planetary health goals. Because of their frequently isolated geographic locations, seasonal fluctuations in energy demand, and limited capacity to invest in new technologies, fisheries and aquaculture face unique energy difficulties.
These industries, as well as the food chain as a whole, will be burdened by rising fuel prices and legislative actions to cut carbon emissions, which will have an impact on food prices and the viability of domestic industry. To strike a balance between the interests of domestic producers, food security, and sustainability, these problems will need for context-specific solutions and educated debates by stakeholders.
The production of aquatic organisms, or aquaculture, is essential to supplying the world’s food needs. The sector does, however, have issues with energy usage and environmental impact. Here comes renewable energy, a game-changer that could lead aquaculture to a more environmentally friendly and sustainable future.
Solar Aquaculture Farms: Solar energy, which harnesses the power of the sun, is revolutionizing aquaculture farms all over the world. Aquaculture facilities that have solar panels installed benefit from both clean energy generation and shade, which lowers temperature variations in the water. By fostering a healthier habitat for aquatic life, this increases farm productivity as a whole.
Wind Power Offshore Aquaculture:
Wind power is becoming more and more important for offshore aquaculture operations to meet their energy needs. Strategically positioned at sea, wind turbines offer a dependable and sustainable electricity supply. This lessens the ecological impact on coastal areas while also reducing dependency on conventional power sources.
Hydropower Solution:
Hydropower is a renewable energy source that can be used to power inland aquaculture operations. It is obtained from flowing water. Hydropower systems can be integrated by aqua culturists to produce energy and provide a continuous water supply to their fields. This two-pronged strategy encourages sustainability and maximizes resource use.
Bioenergy from Organic Waste:
Organic waste produced by aquaculture can be used to produce bioenergy. Organic matter can be transformed into biogas through anaerobic digestion, giving aquaculture operations a sustainable and clean energy source. This closed-loop method helps create a circular economy in addition to reducing trash.
Tidal And Wave Energy Application:
Businesses involved in coastal aquaculture are investigating the possibility of using wave and tidal energy to power their operations. Electricity can be produced by utilizing the energy contained in waves and the tides’ ebb and flow. This creative solution guarantees a steady and dependable electricity supply, even in isolated coastal areas.
Aquaculture can benefit from renewable energy sources since they promote environmental sustainability and increase the sector’s productivity and profitability. Let’s keep encouraging the use of renewable energy sources in aquaculture methods as we work to create a more sustainable future.
