“…For most carnivorous fish species, lipid absorption primarily occurs in the pyloric caeca and the foregut (Denstadli et al, 2004). Several studies have evaluated the effects of different dietary lipids on intestinal morphology, including fat droplet deposition, in fish (Caballero et al, 2002;Castro et al, 2016Castro et al, , 2019Kowalska, Zak, Jankowska, & Siwicki, 2010;Ruyter, Moya-Falcón, Rosenlund, & Vegusdal, 2006). You et al (2019) reported that compared with fish oil, soybean oil and linseed oil significantly decreased the amylase and lipase activities of golden pompano (Trachinotus ovatus).…”

“…Moreover, the replacement of FO with VO can significantly alter the lipase and amylase activities of Nile tilapia (Oreochromis niloticus) (Ayisi, Zhao, & Wu, 2018) and Yellowtail kingfish (Seriola lalandi) (Bowyer, Qin, Adams, Thomson, & Stone, 2012). However, feeding gilthead seabream (Sparus aurata) VO diets had no effect on its digestive enzymes (Castro et al, 2019).…”

An 8-week feeding experiment was conducted to investigate the effects of dietary lipid sources on growth performance, digestive capacity, antioxidant capacity and expression of immune-related genes in the hybrid grouper (Epinephelus fuscoguttatus ♀× E. lanceolatus ♂). Five isoproteic and isolipidic experimental diets were formulated containing fish oil (FO), soybean oil (SO), linseed oil (LO), rapeseed oil (RO) and peanut oil (PO), respectively. Results showed that fish fed the FO diet had the highest weight gain and specific growth rate and the lowest feed conversion ratio. The hepatic aspartate aminotransferase and alanine transaminase activities in the FO group were significantly higher than those in the PO group (p < .05), and the highest total antioxidant capacity was observed in the FO group. Intestinal lipase, trypsin and amylase activities in the LO group were significantly higher than those in the FO and SO groups (p < .05). The mRNA expression levels of Toll-like receptor 3, Toll-like receptor 22 and myeloid differentiation factor 88 in the liver of the PO group were significantly elevated (p < .05), while the mRNA expression of pro-inflammatory cytokines (tumour necrosis factor-α and interleukin-1β) in the RO group was significantly higher than that in the FO group, and the highest mRNA expression of anti-inflammatory cytokines (interleukin-10 and transforming growth factor-β1) was recorded in the FO group. In summary, the FO and LO groups showed better growth performance, while the poor growth performance of the PO group could be attributed to aggravation of the inflammatory response. Finally, LO was recommended as the suitable lipid source replacement for FO.

“…Due to its economic value, many studies on gilthead sea bream intestinal microbiota have been conducted. These studies were mainly focused on defining baseline populations [ 35 – 37 ] or changes induced by diet [ 18 , 38 – 44 ] or environmental conditions [ 45 ]. The microbiota is composed of very dynamic populations that are affected by different factors [ 18 , 36 , 42 , 46 – 55 ] such as diet, season, habitat, rearing density, age, sex, and genetic background, the focus of the current study.…”

Genetic selection for growth drives differences in intestinal microbiota composition and parasite disease resistance in gilthead sea bream

Background The key effects of intestinal microbiota in animal health have led to an increasing interest in manipulating these bacterial populations to improve animal welfare. The aquaculture sector is no exception and in the last years, many studies have described these populations in different fish species. However, this is not an easy task, as intestinal microbiota is composed of very dynamic populations that are influenced by different factors, such as diet, environment, host age, and genetics. In the current study, we aimed to determine whether the genetic background of gilthead sea bream (Sparus aurata) influences the intestinal microbial composition, how these bacterial populations are modulated by dietary changes, and the effect of selection by growth on intestinal disease resistance. To that aim, three different groups of five families of gilthead sea bream that were selected during two generations for fast, intermediate, or slow growth (F3 generation) were kept together in the same open-flow tanks and fed a control or a well-balanced plant-based diet during 9 months. Six animals per family and dietary treatment were sacrificed and the adherent bacteria from the anterior intestinal portion were sequenced. In parallel, fish of the fast- and slow-growth groups were infected with the intestinal parasite Enteromyxum leei and the disease signs, prevalence, intensity, and parasite abundance were evaluated. Results No differences were detected in alpha diversity indexes among families, and the core bacterial architecture was the prototypical composition of gilthead sea bream intestinal microbiota, indicating no dysbiosis in any of the groups. The plant-based diet significantly changed the microbiota in the intermediate- and slow-growth families, with a much lower effect on the fast-growth group. Interestingly, the smaller changes detected in the fast-growth families potentially accounted for more changes at the metabolic level when compared with the other families. Upon parasitic infection, the fast-growth group showed significantly lower disease signs and parasite intensity and abundance than the slow-growth animals. Conclusions These results show a clear genome-metagenome interaction indicating that the fast-growth families harbor a microbiota that is more flexible upon dietary changes. These animals also showed a better ability to cope with intestinal infections.
