Trends in aquaculture sciences: from now to use of nanotechnology for disease control

Abstract

Aquaculture is increasingly important in global food production. Consequently, the control of diseases in aquaculture is essential, due to the potential environmental impacts, notably in terms of the states of health of freshwater bodies and the oceans. In this study, we review the possible uses of different management systems, highlighting essential oils and novel nanotechnological strategies, for the control of diseases in aquaculture.

Nanoemulsions with oleoresin of Copaifera reticulata (Leguminosae) improve anthelmintic efficacy in the control of monogenean parasites when compared to oleoresin without nanoformulation

“…Nanotechnology has been the focus of aquaculture research due to the need of effective delivery systems for certain phytotherapeutic agents (Luis et al, 2019; Shah & Mraz, 2019). The most recent approach to the control and treatment of monogenean infections relies on plant‐derived phytotherapeutics to prepare nanoemulsions.…”

“…Therefore, C. macropomum showed tolerance to all nanoemulsion concentrations, which were low when compared to the concentrations of the C. reticulata oleoresin without nanoformulation. Nanoemulsions are advantageous because they improve bioavailability, solubility and biological accessibility of phytotherapeutics (Luis et al, 2019; Shah & Mraz, 2019), while having low toxicity to the fish. The anthelmintic efficacy of the C. reticulata oleoresin was notably inhibited by poor water solubility, which reduces bioavailability.…”

“…Nanotechnology is an emerging technology with applications in industrial aquaculture, having the potential to enhance production and ultimately contribute to global food security (Luis, Campos, Oliveira, & Fraceto, 2019; Shah & Mraz, 2019; Valentim et al, 2018a, 2018b). Nanobiotechnology is among the recent advancements of nanotechnology and is used specifically in the treatment of diseases in aquaculture (Luis et al, 2019; Pimentel‐Acosta et al, 2019; Shah & Mraz, 2019). Hence, nanotechnology can reduce economic losses caused by mass mortality in commercial aquaculture.…”

“…(Arruda et al, 2019; Trindade, Silva, & Setzer, 2018), including anthelmintic activity against monogeneans in fish (Costa et al, 2017; Valentim et al, 2018b). Hence, there exists a growing interest in the use of oleoresins and essential oils and their bioactive compounds for treating fish infected by monogeneans (Luis et al, 2019; Morales‐Serna et al, 2019; Tavares‐Dias, 2018). However, oleoresins and essential oils have low water solubility and low bioavailability, which are major disadvantages for use in fish farming (Costa et al, 2017; Tavares‐Dias, 2018; Valentim et al, 2018a, 2018b).…”

Diphenyl diselenide‐loaded nanocapsules in silver catfish feed enhance growth, improve muscle antioxidant/oxidant status and increase selenium deposition: Advantages of nanotechnology for fish health

“…Despite the positive properties of Ph 2 Se 2 , its use in the fish industry has been hampered by its inability to enhance growth. For these reasons, strategies to adapt Ph 2 Se 2 for use as a growth promotor should be explored, including the use of nanotechnology (Luis, Campos, de Oliveira, & Fraceto, 2019; Shah & Mraz, 2019).…”
