“…Yunlong Grouper is a hybrid progeny ( Epinephelus moara♀ × E. lanceolatus♂ ) with fast growth, a high survival rate, and wide temperature range. Researchers have reported on their embryonic (Tian et al 2017a) and post-embryonic development (Wu et al 2016a, b, c), the adaptability of fry to temperature and salinity (Xing et al 2017), and karyotype analysis (Cheng et al 2018). However, there has been no research using 16S rRNA gene sequencing to analyze the intestinal microflora of Yunlong Grouper in different health states, nor studies of the correlation between composition of the intestinal microflora and the culture environment.…”

Maintaining stabilization of the intestinal microbiota is important in preventing bacterial diseases in cultured fish. At present, there have been no reports on the composition and functional analysis of intestinal microbiota in Yunlong Grouper (Epinephelus moara♀ × Epinephelus lanceolatus♂). In this study we analyzed and compared the intestinal microbiota composition of healthy and diseased pond-reared fish to discern the functional profile of a healthy status. The richness and diversity of the intestinal microbiota did not differ significantly between diseased and healthy fish, yet the abundance of predominant phyla like the Proteobacteria were upregulated in the diseased Yunlong Grouper. At the genus level, a significant reduction of Cetobacterium was observed in the intestinal tracts of diseased fish, as Pseudomonas became the most dominant bacterium. To compare the intestinal microorganism abundances between the two health groups of fish, we first screened the gut bacteria and discerned 4 phyla and 12 genera to designate a healthy status in Yunlong Grouper. The environmental bacterial community influenced composition of the intestinal microbiota in Yunlong Grouper, and the intestinal microbiota of diseased fish was more susceptible to the influence of the culture water. In addition, the prediction of functional genes by phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) indicated that the intestinal microbiota of Yunlong Grouper is related mainly to the terms “metabolism, environmental information processing, genetic information processing, human diseases, and cellular processing; moreover, the functions of the intestinal microbiota differed between the different health states of this fish. The overall results indicate that the occurrence of disease can affect the composition and function of the intestinal microbiota in a cultured fish.

“…Fishmeal, which contains balanced essential amino acids and high growth-promoting factors and exhibits high digestibility, has been used as a major source of protein for marine fish feed [5,6]. However, with an increase in demand and the shortage of production, the price of fishmeal is constantly rising, which greatly affects the feeding cost [7]. Therefore, many enterprises and research scholars urgently need to look for cheaper and more sustainable alternative protein sources to replace fishmeal [8,9] so as to promote the healthy development of grouper aquaculture.…”

Clostridium autoethanogenum protein (CAP) is an economical and alternative protein source. Here, three experimental diets were formulated with CAP replacing 0% (CAP-0), 30% (CAP-30), and 60% (CAP-60) of fishmeal to investigate the alterations of structure integrity, fatty acids profiles, and lipid metabolism in the muscle of pearl gentian grouper. With increasing levels of CAP substitution, the percentages of 16 : 0 or 18 : 0 were decreased in triglycerides (TG) and diacylglycerols (DG); 18 : 1 or 18 : 2 was increased at the sn−1 and sn−2 positions in phosphatidylethanolamines; 20 : 5n−3 was increased in TG and DG. The phosphatidylcholines (PC) (18 : 3/20 : 5), PC(22 : 6/17 : 1), and sphingomyelins (d19 : 0/24 : 4) were identified as potential lipid biomarkers between CAP treatments. The CAP-30 treatment enhanced lipolysis and lipogenesis, while the CAP-60 treatment inhibited lipogenesis. In conclusion, fishmeal replacement with CAP affected the lipid characteristics and lipid metabolism, whereas it did not affect the structural integrity and fatty acids profiles in the muscle of pearl gentian grouper.
