“…Importantly, the homology of FSHb and LHb to bluefin tuna was very high. Bluefin tuna is a commercially important cultured fish species, and reproductive problems such as the inhibition of FOM and a late age of sexual maturity is a serious issue (Corriero et al 2007(Corriero et al , 2009. It is difficult to analyze the physiological mechanism regulating gametogenesis in reared bluefin tuna because the adult body size is very large (30-150 kg) (Sawada et al 2005).…”

“…The most common dysfunctions in females are: absence of gonadal development [99]; failure of oocytes to undergo oocyte maturation (also referred to as final oocyte maturation) once vitellogenesis is completed [19, 100, 101]; or absence of spawning [102]. Production of low amount of expressible semen in males [103], as well as reduction of germ cell proliferation and increase of apoptosis [20, 104] has been reported in captive-reared male fish. Atresia of vitellogenic oocyte and failure to undergo oocyte maturation have been attributed to an insufficient pituitary luteinizing hormone (LH) release, and to the consequent steroid withdrawal, occurring in captive conditions [105, 106].…”

“…In captive Atlantic bluefin tuna, the administration of GnRHa through a controlled‐release delivery system (Mylonas et al., ) was correlated with an increase in plasma LH levels, as well as 11‐KT (Rosenfeld et al., ). The detection of a lower density of apoptotic germ cells in GnRHa‐treated fish was attributed to the increase in testicular 11‐KT production, which was stimulated by the GnRHa‐induced LH release from the pituitary (Corriero et al., ). It may be speculated that the differences observed in apoptotic rates between wild and captive fish may be due to differences in their corresponding plasma levels of 11‐KT, but this cannot be confirmed since no blood could be obtained from the wild fish.…”
