“…Several grouper species have been considered for farming in both Americas, including Nassau grouper (Epinephelus striatus), gag grouper (Mycteroperca microlepis), black grouper (Mycteroperca bonaci), and jewfish (Epinephelus itajara) in the south-eastern United States and Caribbean (Tucker 2005) and dusky grouper (E. marginatus) in Brazil (Kerber et al 2012). However, of these only E. striatus has been investigated by several research groups (Tucker et al 1991;Tucker 1994;Watanabe et al 1995). Traditional Asian-style grouper farming was not seen as appropriate for the United States because inshore areas suitable for cage culture are very rare in the southern United States and collection of wild juveniles for culture activities is considered as unethical and illegal (Tucker 2005).…”

Aquaculture of groupers is carried out in tropical and subtropical areas throughout the world, but most production is from Asia, with three countries responsible for an estimated 92% of global production: China (65% of total production), Taiwan Province of China (17%) and Indonesia (11%). We calculate that there are at least 47 grouper species plus 15 grouper hybrids that have been trialled or are currently aquacultured. While grouper aquaculture has undoubtedly provided positive social and economic benefits to coastal communities in Asia, practices associated with grouper aquaculture have also led to widespread concerns regarding its environmental impacts. This paper reviews environmental, economic and social impacts of grouper aquaculture within a sustainability science framework. An update, building on early technical reviews of grouper aquaculture, was used to identify the main environmental, economic and social impacts. The main environmental impacts identified were as follows: seedstock sources, particularly the use of wild‐caught postlarval or juvenile fish as seedstock; the use of ‘trash’ fish as the major feed source; and water quality and substrate impacts of sea cage aquaculture. Significant economic and social impacts arising from grouper aquaculture include employment and income generation, but the economic impacts of disease outbreaks are significant, reducing fish survival to harvest size to around 50–70%. Current approaches to ameliorate negative impacts include the following: development and implementation of better management practices (BMPs) at national level, and the development of a global ecolabel certification scheme by the Aquaculture Stewardship Council. Both these approaches have significant constraints, particularly when applied to small‐scale farmers who produce the bulk of farmed grouper. We conclude that there is a need for improved higher level coordination between the major producer countries to address identified sustainability constraints to grouper aquaculture.

“…Spontaneous maturation and ovulation in sevenband grouper have not been completed in artificial conditions. Treatment with GtH or gonadotropin‐releasing hormone (GnRH), a hypothalamic hormone that stimulates GtH synthesis and release, is an effective method to induce maturation and ovulation in marbled grouper E. microdon, 11 dusky grouper E. marginatus 12 and Nassau grouper E. striatus 13–15 . Effective use of this technique, however, requires information on the reproductive cycle and gonadal development in the target species.…”

Ovarian development and final oocyte maturation in cultured sevenband grouper Epinephelus septemfasciatus

The histological changes in the ovary of sevenband grouper Epinephelus septemfasciatus were examined during vitellogenesis and final oocyte maturation. Ovaries contained oocytes at the perinucleolus stage at the start of the experiment in January. Oocytes at the primary yolk stage appeared when the gonadosomatic index (GSI) was slightly on the rise in March. After that, vitellogenesis progressed and ovaries contained oocytes at the tertiary yolk stage in May. The GSI increased drastically at the same time. These results suggest that vitellogenesis in sevenband grouper starts or is already in progress in March and is completed by May, In order to clarify the process of final oocyte maturation, luteinizing hormone-releasing hormone (LHRH) analog (des Gly 10 , [D-Ala 6 ] LHRH ethylamide) was implanted in fish with oocytes at the tertiary yolk stage. The oocytes developed to the migratory nucleus stage in 18 h and reached the maturation stage in 42 h after implantation. This indicates that final oocyte maturation is completed within 42 h after stimulation of gonadotropinreleasing hormone.KEY WORDS: estradiol-17β β β β , final oocyte maturation, gonadosomatic index, LHRHa, ovarian development, sevenband grouper.

“…Artificial propagation of temperate and tropical reef fishes in North America, including gags Mycteroperca microlepis (Roberts and Schlieder 1983), red grouper Epinephelus morio (Colin et al 1996), Nassau grouper E. striatus (Tucker et al 1991;Tucker and Woodward 1996;Watanabe et al 1996), black seabass Centropristis striata Watanabe et al 2003), mutton snapper Lutjanus analis, yellowtail snapper Ocyurus chrysurus, and red snapper L. campechanus (Watanabe et al 2005), is challenged by controlled spawning in captivity, larval first feeding and survival through metamorphic stages, and temperature demands during grow-out phases. Based on results of this study, the potential for red porgy culture in North America appears optimistic.…”

Aquaculture of the Atlantic Red Porgy

Aquaculture of red porgy Pagrus pagrus (Sparidae) in North America was assessed by the investigation of broodstock conditioning and egg production, larval growth and survivorship, and juvenile grow out. Red porgy broodstock were collected off the coast of North Carolina and held in an outdoor recirculating seawater tank under ambient photoperiod and offshore bottom temperatures. Red porgy broodstock (n ¼ 20) produced up to 300,000 viable eggs/d during their natural spawning period between January and March 2005. Larval survival to 10 d posthatch (dph) was 75.0 6 2.2% (mean 6 SE). Survival declined markedly after 13 dph and was 2.4% by 35 dph, when 1,200 postmetamorphic-stage juveniles remained. Larvae reached 11.2 6 1.12 mm and 29.3 6 0.55 mg at 35 dph, and juveniles reached 55 mm total length (TL) at 90 dph. Juvenile grow-out trials in recirculating tanks resulted in red porgy reaching 195 6 0.32 mm TL and 158 6 0.14 g at 313 dph and a weight-specific growth rate of 6.8%. The results suggest a lower larval growth rate for western Atlantic red porgy compared with Mediterranean red porgy culture; however, juvenile growth rates were significantly higher than previously reported. Given the high market demand for reef fish species, the red porgy appears to be a good candidate for marine fish culture in North
