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.

“…Hirai et al (2012) in their study showed that P. similis was suitable for the rearing of humphead wrasse (Cheilinus undulatus) larvae at the start of feeding. Other research on seven band grouper (Epinephelus septemfasciatus) larvae (Wullur et al, 2011) and Japanese eel (Anguilla japonica) larvae (Hagiwara, Wullur, Marcial, Hirai, & Sakakura, 2014;Wullur et al, 2013) has resulted in similar conclusion.…”

Fish-processing wastes as an alternative diet for culturing the minute rotiferProales similisde Beauchamp

We evaluated the suitability of fish waste diet (FWD) for culturing the minute rotifer Proales similis through the observation of their population growth and particle size selective feeding. A total of five treatments either with Nannochloropsis oculata or FWD (0.75 and 0.50 g/L) or the combination of N. oculata and FWD were set up in triplicates. P. similis were cultured in diluted natural seawater (8 g/L salinity) and 26 ± 1°C with the diet treatments being applied randomly. We daily monitored the rotifer density, the number of bacteria and the water quality in all the cultures. The population density of P. similis increased exponentially in all treatments, while the mean growth in FWD 0.75 g/L was significantly higher (p < .05) than that in the control. Addition of N. oculata to FWD resulted to lowered P. similis population growth. Bacterial colony count was high in FWD and introduction of P. similis to the diet decreased their density. The estimated bacteria ingestion rates were generally in the range of 6.03 × 102–1.24 × 104 bacteria/rotifer/hr and there was a positive linear relationship between bacterivory and rotifer population growth. We also observed a shift in the particle size distribution with a reduction in the frequency and concentration of small‐sized particles (<2.5 μm) at day 6. These results accentuate the potential of fish‐processing waste as diet for culturing P. similis which feeds on bacteria and small particles (≤2.5 μm) that are by‐products of degradation of this diet.

“…In this work, we studied the rotifer P. similis, a highly relevant rotifer because it is a native species of northwestern Mexico that has great potential for use as live feed in the larviculture of marine fish with extremely small mouths, as has been documented by Wullur et al, (2009) and Hagiwara et al, (2014) for P. similis from the estuarine waters of Okinawa, Japan. However, strains of the same species with different geographic origins can have different biological characteristics and environmental requirements as a result of different genetic backgrounds (Yin & Zhao, 2008;Malekzadeh-Viayeh et al, 2010); thus, it is important to evaluate the potential for growth of the different native strains recently identified.…”

“…There have been recent studies on the management and production of rotifers belonging to other taxonomic genera, notably a series of papers presented by Wullur, Sakakura, and Hagiwara (2009);Wullur, Sakakura, and Hagiwara (2011);Hirai, Koiso, Teruya, Kobayashi, Takebe, Sato, Nakamura, Goto, and Hagiwara (2012) ;Wullur, Yoshimatsu, Tanaka, Ohtani, Sakakura, Kim, and Hagiwara (2013); Hagiwara, Wullur, Marcial, Hirai, and Sakakura (2014) and Tomoda, Furuita, Kamoshida, Kurogi, Shibuno, Tanaka, and Tezuka (2014), in which they describe some biological and nutritional characteristics of the rotifer Proales similis, which was isolated from an estuary in the Ishigaki island, Okinawa, Japan, and was used successful in the first feeding of larval fish with extremely small mouths. They described this species as a small size (80±3.4 µm), soft-bodied (aloricated) rotifer that reaches high densities in laboratory cultures.…”

The effect of different salinities on growth, crude protein and total energy on a Mexican strain of the minute rotifer Proales similis (GenBank KM078762) were evaluated. The experiment was conducted at 5, 15, 25 and 35 psu, with five replicates. Rotifers were fed twice a day with Nannochloropsis sp., temperature, dissolved oxygen and pH values were maintained at 25±1°C, 5±1 mg L -1 and 8±1 respectively. Results show that salinity does not affect the intrinsic rate of population growth (r=0.46 to 0.51 day -1 ) and duplication time (Dt=1.36 to 1.51 days) for P. similis. Maximum density (Dmax) values were lower at 35 psu (1,703 rotifers ml -1 ), whereas Dmax values were between 2,488 to 2,560 rotifers ml -1 at 5, 15 and 25 psu. Crude protein fluctuated between 25.3 and 42.8% dry biomass (DB), while energy content varied between 11.8 and 19.9 J mg -1 DB; values were significantly lower at 35 psu. Observed population growth parameters and the protein and energy content between 5-25 psu, indicate that P. similis can be successfully reared below 35 psu, making P. similis very suitable when fish larvae require a small rotifer due to sizing of mouth gap at the beginning of exogenous feeding.
