“…Groupers are among the most common fish and extremely merchandized seafood in the Asia-Pacific region (FAO, 2020). Due to its rapid growth rate, hardiness to environmental conditions, high disease resistance, and high nutritional value, it is an ideal species for intensive aquaculture (Ch'ng and Senoo, 2008;Jiang et al, 2015;Arrokhman et al, 2017;Bunlipatanon and U-taynapun, 2017). With regard to marine fish culture output in China, groupers are ranked third (Yang et al, 2021).…”

“…Hybrid grouper with a higher disease resistance, faster growth rate, and better feed conversion ratio (FCR) was produced at the University of Malaysia Sabah from brown-marbled grouper (Epinephelus fuscoguttatus ♀) and giant grouper (Epinephelus lanceolatus ♂) (Rahimnejad et al, 2015;Firdaus et al, 2016). The hybrid produced grows to 1 kg in a period of 6-7 months, while the parents require 8 months to 1 year to attain a similar weight (Arrokhman et al, 2017).…”

The effect of hydrolyzed fish protein powder (HFP) on the growth, intestinal development, gene mRNA expression, and enzyme activity in the intestine and liver of juvenile hybrid grouper (Epinephelus fuscoguttatus ♀ and Epinephelus lanceolatus ♂) was assessed after an 8-week feeding trial. Seven isonitrogenous (50%) and isolipidic (9%) diets were fed to hybrid grouper with 0% (CT), 1% (H1), 1.5% (H2), 2% (H3), 2.5% (H4), 3% (H5), and 4% (H6) HFP. No significant difference (p > 0.05) in weight gain rate (WGR), specific growth rate (SGR), feed conversion ratio (FCR), and survival rate (SR) was observed in all the groups. The crude protein content in the H6 group was significantly higher than in the other groups (p < 0.05). Intestinal lipase and trypsin activity were significantly higher in H3 and H5 groups (p < 0.05). In the serum, superoxide dismutase (SOD) activity was significantly higher in H5 and H6 groups, while malondialdehyde (MDA) activity was lower (p < 0.05) compared to other treatments. Insulin-like growth factor (IGF-I) and target of rapamycin (TOR) mRNA expression levels in the intestine and muscle were significantly higher in the H2 group and H1 group (p < 0.05), respectively. The most abundant intestinal bacteria found at the genus level are Acinetobacter, Vibrio, and Flavobacteriaceae. The villus was significantly longer in hybrid grouper fed with different levels of HFP compared to the control, and fish in the H2 group had thicker intestinal muscle compared to the other groups (p < 0.05). In conclusion, the addition of HFP to the low fishmeal (FM) diets of juvenile grouper improved the intestinal development and increased the levels of intestinal digestive enzymes.

“…Since then, this hybrid grouper has become one of the most popular grouper species in Southeast Asia's aquaculture industry. Its popularity is due to its high egg‐hatching rate and larval survival, fast growth, higher tolerance to environmental variations, and greater resistance against diseases compared to the parental species (Arrokhman et al, 2017; Bunlipatanon & U‐taynapun, 2017; Koh et al, 2016; Othman et al, 2015; Mustafa et al, 2013; Ch'ng & Senoo, 2008, Shapawi et al, 2019).…”

Effects of dietary L‐ascorbyl‐2‐polyphosphate on growth performance, haematological parameters, biochemical characteristics, and skeletal features of juvenile hybrid grouper (♀Epinephelus fuscoguttatus × ♂E. lanceolatus)

A 14‐week feeding trial was conducted to determine the effects of dietary L‐ascorbyl‐2‐polyphosphate on the growth performance, haematological parameters, biochemical characteristics, and skeletal features of juvenile hybrid grouper (♀Epinephelus fuscoguttatus × ♂E. lanceolatus). Eight experimental diets containing graded vitamin C (VC) levels (0, 18, 45, 78, 144, 245, 386, and 762 mg/kg) were prepared and fed to triplicate groups of fish (initial body weight: 10.41 ± 0.06 g). The final body weight, weight gain rate, specific growth rates, and fish survival increased when fed with diets supplemented with VC regardless of the supplementation level. Total feed intake reduction was observed in fish fed non‐VC diet. Whereas no significant differences were detected in the feed conversion ratios and protein efficiency ratios among fish treatments. The hepatic VC concentration was positively correlated with dietary VC supplementation and reached a plateau when supplemented with more than 386 mg/kg diet. Higher total protein and alkaline phosphatase levels in blood serum and incidence of skeletal deformities were recorded in the fish fed with a control diet compared to other treatments. The results indicate that adding 18 mg/kg of VC is optimum and further increase does not provide any significant benefit to fish growth and health.

“…The hybrid grouper had then become a popular aquaculture fish in Malaysia and other South-east Asian countries. It has high aquaculture demand due to its high egg hatching rate, faster growth, strong tolerance to the environmental factors and resilience to diseases than its parental species (Mustafa et al, 2013;Othman et al, 2015;Koh et al, 2016;Bunlipatanon and U-taynapun, 2017;Arrokhman et al, 2017).…”

This study was done to investigate the effects of fish oil (FO) replacement with different types vegetable oils (VO) on the growth performance, feed utilisation and fatty acid profile of hybrid grouper juvenile (Ephinephelus fuscoguttatus,) x giant grouper (Epinephelus lanceolatus,). Six isoprotein (50%) and isolipid (12%) diets were formulated using 100% FO (as the control) and 50% of FO was replaced with crude palm oil (CPO), refined, bleached and deodourised (RBD) palm olein (POo), crude palm kernel oil (CPKO), corn oil (CO) and coconut oil (COCO). Triplicate groups of hybrid grouper juvenile (11.12±0.04 g) were fed with the experimental diets for a period of 12 weeks. Fish fed with RBD POo diet showed significantly higher growth and slightly better feed efficiency than other diets. The different VO affected the body indices, whole body proximate composition and fatty acid profile of the muscle and liver. However, the survival of fish was not affected by the different diets. Present study suggests that RBD POo is the most suitable VO for hybrid grouper.
