Cover Story: Beginning in 2002, New Zealand’s National Institute of Water and Atmospheric Research (NIWA) established a breeding program for the wreckfish (Polyprion oxygeneios), locally known as ‘hāpuku’. Wild-caught hāpuku spawn readily in captivity, but although first filial (F1) hāpuku complete vitellogenesis, females fail to undergo oocyte maturation and spawn or produce poor-quality eggs. We examined whether administration of a synthetic agonist of gonadotropin-releasing hormone (GnRHa) could improve F1 hāpuku spawning in captivity. This study successfully achieved two key aims: induction of spawning with GnRHa and closing of the life-cycle of hāpuku by producing second generation offspring. View this paper.
