Reproduction of greater amberjack (Seriola dumerili) and other members of the family Carangidae

Abstract

The family Carangidae contains several species of aquaculture interest, including the amberjacks, yellowtails and trevallies. Among them, the greater amberjack (Seriola dumerili), the Japanese amberjack or yellowtail (Seriola quinqueradiata) and the yellowtail kingfish (Seriola lalandi) are considered the species with the highest potential for commercial aquaculture. Understanding the reproductive physiology-biology, spawning kinetics and production characteristics in captivity are of utmost importance for the domestication of any animal, and developing broodstock management methods and therapies to optimize egg production and overcome potential reproductive dysfunctions are essential. The present article reviews the available literature on the reproductive biology of the Carangidae species of interest for the aquaculture industry, both in the wild and under farming conditions. The reproductive traits of wild and farmed fish, whenever available, were compared in order to improve the understanding of the reproductive dysfunctions occurring in captivity. Finally, the hormonal maturation and spawning induction protocols examined so far to ameliorate the reproductive dysfunctions and obtain fertile gametes are summarized, and their effectiveness in the different rearing conditions is discussed.

Atresia of ovarian follicles in fishes, and implications and uses in aquaculture and fisheries

“…As reported above, follicular atresia is a normal component of fish oogenesis and it is observed throughout the ovarian cycle, although it is more frequent in regressing ovaries during the postspawning period (Ganias et al., 2008 ; Miranda et al., 1999 ; Saidapur, 1978 ). Generally, follicular atresia does not preclude the reproductive success of fish populations; however, an increase of the atretic rate beyond physiological rates can reduce the annual fecundity and even cause reproduction failure of both wild (Ganias et al., 2008 ; Hunter et al., 1992 ; Jørgensen et al., 2006 ; Kraus et al., 2008 ; Kurita et al., 2003 ; Neves et al, 2009 ; Rideout et al., 2005 , Rideout and Tomkiewicz, 2011 ; Witthames & Greer Walker, 1995 ) and captive‐reared fish stocks (Corriero, Desantis, et al., 2007 ; Corriero, Medina, et al., 2007 ; Corriero et al., in press ; Fakriadis, Miccoli, et al., 2020 ; Kjesbu et al., 1991 ; Ma et al., 1998 ; Mylonas et al., 2010 ; Pousis et al., 2018 , 2019 ; Zupa et al., 2013 ; Zupa, Fauvel, et al., 2017 ; Zupa, Rodríguez, et al., 2017 ). Extensive follicular atresia and spawning omission are the most efficient strategy to optimize fecundity in case of low body energy reserves (Kennedy et al., 2008 ; Rideout et al., 2000 , 2005 ) and, in general, the lower the food intake the higher the proportion of atretic vitellogenic follicles (Kennedy et al., 2008 ; Kjesbu et al., 1991 ; Ma et al., 1998 ; Scott, 1962 ).…”

The genome of New Zealand trevally (Carangidae: Pseudocaranx georgianus) uncovers a XY sex determination locus

“…The trevally genome will be useful to assemble other Carangidae fragmented genomes based on synteny, such as other Seriola spp. which are economically important for aquaculture around the globe (Corriero et al 2021). We demonstrate the usefulness of this genome assembly and annotation for mapping the SD locus, which supports a XX/XY model for trevally and enabled us to develop robust PCR-based markers for sex identification in this species.…”
