“…The greater amberjack Seriola dumerili (Risso, 1810) is an epibenthic and pelagic teleost species distributed in the Indo‐West Pacific (Paxton, Hoese, Allen, & Hanley, ), western Atlantic (Cervigón, ; Smith, ) and eastern Atlantic oceans as well as in the Mediterranean Sea (Bauchot, ). Thanks to its rapid growth rate, high flesh quality and consumers' appreciation, the greater amberjack is a promising new aquaculture species (Fakriadis, Lisi, Sigelaki, Papadaki, & Mylonas, ).…”

The greater amberjack Seriola dumerili is a new aquaculture fish that may display reproductive dysfunctions. During extensive follicular atresia, which is a common reproductive dysfunction in females during vitellogenesis, part of the reabsorbed yolk returns to the liver to be metabolized and recycled. Melanomacrophage centres (MMCs) are aggregates of macrophage‐like cells that play a role in the destruction, detoxification and recycling of endogenous and exogenous materials, and have been associated with systemic stress. Wild and captive‐reared greater amberjack were sampled in the Mediterranean Sea during two different phases of the reproductive cycle. The liver of reproductively dysfunctional captive‐reared females sampled during the spawning season showed a high density of both MMCs and apoptotic cells. A weak liver anti‐cytochrome P450 monooxygenase 1A immunoreactivity was observed, suggesting that the examined fish were not exposed to environmental pollutants. We propose that the observed increase in MMCs and apoptosis in captive‐reared fish was related to the hepatic overload associated to the metabolism of yolk proteins reabsorbed during extensive follicular atresia. Since follicular atresia is a frequent physiological and pathological event in teleosts, we suggest that the reproductive state should be always assessed when MMCs are used as markers of exposure to stress or pollutants.

“…Fakriadis et al . () examined egg production and quality from spawning induced by GnRHa implants compared with multiple GnRHa injections. This revealed that the GnRHa implant was more effective because GnRHa‐implanted females produced more eggs compared with GnRHa‐injected females.…”

“…Fakriadis et al . () demonstrated GnRHa implant use was more effective for improved egg production and quality than multiple GnRHa injections. Based on the multiple spawning of greater amberjack and the sustained elevation of plasma GnRHa achieved by the cholesterol implants, we cannot exclude the potential of long‐term GnRHa stimulation of Fsh release in post‐vitellogenic greater amberjack.…”

“…Because of its large size and fast growth rate, the greater amberjack Seriola dumerili (Risso 1810) is a major aquaculture species in Japan and an important emerging species in southern Europe (Fakriadis et al, 2019;Jerez et al, 2018;Nakada et al, 2002;Navarro-Guillén et al, 2019). With the increasing demand for this species, many studies, including reproductive control and seed production, have been recently conducted to establish a sustainable aquaculture industry (Fernández-Palacios et al, 2015;Matsunari et al, 2013;Zupa et al, 2017).…”

In the Mediterranean Sea and Canary Islands, GnRHa implants have been used successfully to induce continuous spawning of greater amberjack from a few weeks (Fakriadis et al, 2019) to months (Jerez et al, 2018). Fakriadis et al (2019) examined egg production and quality from spawning induced by GnRHa implants compared with multiple GnRHa injections.…”

The effects of gonadotropin‐releasing hormone agonist (GnRHa) on plasma levels of follicle‐stimulating hormone (Fsh) and luteinising hormone (Lh) are reported for female greater amberjack Seriola dumerili with post‐vitellogenic ovarian oocytes. Five females were implanted with pellets containing GnRHa (600 μg kg−1 body weight), while five other females were injected with saline. All females implanted with GnRHa‐containing pellets ovulated 36–42 h post‐implantation. The GnRHa implants elevated Lh, but not Fsh plasma levels within 42 h of GnRHa administration.
