Essential oil of Alpinia zerumbet (Zingiberaceae) has anthelmintic efficacy against monogenean of Colossoma macropomum (Characiformes: Serrasalmidae)

Abstract

The world population is estimated to reach close to 10 billion inhabitants by 2050, thus increasing the global demand for energy, drinking water and food (ONU, 2019). Given this scenario and the decline of natural fish stocks, aquaculture has been the subject of rapid development. Aquaculture has grown faster than other major food production sectors as it contributes to the supply of animal protein of high biological value for human consumption, job creation and income, thereby boosting the economic development of several countries (FAO, 2018).However, aquaculture activities around the world have suffered from outbreaks of parasitic diseases, which cause losses in production and affect profitability and sustainability (Assefa & Abunna, 2018).Losses in aquaculture caused by parasitic diseases are estimated at US $ 1.05-9.58 billion/years (Shinn et al., 2015). Losses from parasitic diseases are also attributed to stressful handling conditions, high stocking densities and inadequate water quality during the cultivation.Parasitic diseases in fish farming include those caused by monogeneans, which are ectoparasites with simple and direct life cycle.These ectoparasites can cause significant losses in farmed fish for

Anthelmintic efficacy of Copaifera reticulata oleoresin in the control of monogeneans and haematological and histopathological effects on Colossoma macropomum

“…In the last decades, nanotechnology had diverse new developments in almost every field of science and technology, including the biology, because the nanotechnology presents a great opportunity to develop effective products for controlling pathogenic agents, for example the use in control of monogeneans of fish (Malheiros et al, 2020;Valentim, Duarte, Oliveira, Cruz, Carvalho, Conceição et al, 2018;Valentim, Duarte, Oliveira, Cruz, Carvalho, Solans et al, 2018). Therapeutic (Luz et al, 2021). This hyperglycaemia is indicative of stress in fish submitted to therapeutic baths with these phytotherapics.…”

“…This hyperglycaemia is indicative of stress in fish submitted to therapeutic baths with these phytotherapics. Total protein level depends on intracellular mechanisms and specific proteins that can be affected by stress fish (Luz et al, 2021)…”

“…Gonzales et al (2020) reported also an increase in plasma glucose levels in C. macropomum exposed to 60 mg/L of Cymbopogon citratus essential oil. In contrast, therapeutic baths of C. macropomum with 300 mg/L of Alpinia zerumbet essential oil decreased the levels of plasma glucose and total protein (Luz et al, 2021). This hyperglycaemia is indicative of stress in fish submitted to therapeutic baths with these phytotherapics.…”

“…In the last decades, global aquaculture industry has succeeded and continues to increase while achieving the critical goals of environmental, economic and societal sustainability. Aquaculture is, therefore, the fastest growing agricultural activity, but it needs technological innovations to achieve improvements in the health management of farmed fish and thus avoid parasitic outbreaks and economic losses, which are the main obstacles to the development of this activity on an industrial scale (Luz et al, 2021; Soler‐Jiménez et al, 2017; Tavares‐Dias, 2018). In this scenario, the nanotechnology can reduce the economic losses caused by mass mortality in fish farming, as it has emerged as a new science and technology platform aimed at the development and transformation of agrifood systems, producing more qualified and disease‐free products (Luis et al, 2019; Malheiros et al, 2020; Pimentel‐Acosta et al, 2019; Shah & Mraz, 2020).…”

“…Currently, there is a growing search for environmentally friendly antiparasitic treatments, such as the use of oils derived from medicinal plants (Costa et al, 2017; Gonzales et al, 2020; Ling et al, 2015; Luz et al, 2021; Morales‐Serna et al, 2019; Soares et al, 2016; Tavares‐Dias, 2018). However, essential oils and oleoresins may have the desired efficacy compromised, due to low water solubility, which is the major disadvantages for the use in fish farms (Costa et al, 2017; Malheiros et al, 2020; Tavares‐Dias, 2018).…”
