“…Offshore mariculture requires cages positioned in deeper and less sheltered waters, away from the coast [80,81], a practice that requires new technologies and the development of systems to avoid the strong currents, winds, and waves of more open areas. Indeed, to contrast the high-energy offshore environment, structures must be more robust than those utilized inshore [80], with submerging cages or shellfish culture systems minimizing and reducing the wave effects and interference caused by boating and shipping [80,82]. The cost of maintaining an offshore system is higher than that of inshore systems.…”

“…Indeed, offshore aquaculture can provide more space to expand production, avoiding conflicts that occur with other possible uses of the coast in more crowded inshore waters [81]. This is especially true in countries with few suitable inshore sites [82]. Moreover, offshore aquaculture can also be linked to the multi-functional use of sites-for example, coupling aquaculture with energy production, as occurs in roaming plants with large mobile cages that are able to take advantage of ocean currents [85].…”

In this paper, the different possibilities and innovations related to sustainable aquaculture in the Mediterranean area are discussed, while different maricultural methods, and the role of Integrated Multi-Trophic Aquaculture (IMTA) in supporting the exploitation of the ocean’s resources, are also reviewed. IMTA, and mariculture in general, when carefully planned, can be suitable for environmental restoration and conservation purposes. Aquaculture, especially mariculture, is a sector that is progressively increasing in parallel with the increase in human needs; however, several problems still affect its development, mainly in relation to the choice of suitable sites, fodder production, and the impact on the surrounding environment. A current challenge that requires suitable solutions is the implementation of IMTA. Unfortunately, some criticisms still affect this approach, mostly concerning the commercialization of new products such as invertebrates and seaweeds, notwithstanding their environmentally friendly character. Regarding the location of a suitable site, mariculture plans are currently displaced from inshore to offshore, with the aim of reducing the competition for space with other human activities carried out within coastal waters. Moreover, in open water, waste loading does not appear to be a problem, but high-energy waters increase maintenance costs. Some suggestions are given for developing sustainable mariculture in the Mediterranean area, where IMTA is in its infancy and where the scarce nutrients that characterize offshore waters are not suitable for the farming of both filter feeder invertebrates and macroalgae. From the perspective of coupling mariculture activity with restoration ecology, the practices suggested in this review concern the implementation of inshore IMTA, creating artificially controlled gardens, as well as offshore mussel farming coupled with artificial reefs, while also hypothesizing the possibility of the use of artificially eutrophized areas.

The demand for fish in Nigeria is still not met, despite having a domestic production estimated at about 800,000 metric tonnes. The demand stands at about 2.1 million metric tonnes per year. There is a shortfall of about 1.3 million metric tonnes. To solve this problem Nigeria has turned to fish importation while several other policies are being put in place by successive administrations to improve on local production. However, none of the efforts has been successful so far. The aim of this paper is to assess the potentials of offshore aquaculture within the exclusive economic zone (EEZ) of Nigeria with the view of meeting the fish demand of Nigerians. The paper develops a framework for the operation of offshore aquaculture. The implications of climate change on offshore fish production along the coastal area were highlighted. Strategies and policy measures needed to combat the challenges facing offshore aquaculture in order for it to live to its full potentials in protecting the living welfare of the fishermen and ensuring food security are also discussed.
