“…This gene appears to be a paralogue of those mentioned above from other crustaceans, namely E. sinensis (Yang et al 2013), S. paramamosain (Lin et al 2017), L. vannamei (Chen et al 2017) and C. quadricarinatu (Wu et al 2018). Like observed in M. nipponense (Luo et al 2018), the desaturases from the crabs E. sinensis (Yang et al 2013), Portunus trituberculatus (Wang et al 2014) and S. paramamosain (Lin et al 2017), as well as that from spiny lobster Sagmariasus verreauxi (Shu-Chien et al 2017) were also nutritionally upregulated by dietary vegetable oil, suggesting putative roles in PUFA metabolism.…”

Desaturases and elongases involved in polyunsaturated fatty acid biosynthesis in aquatic invertebrates: a comprehensive review

Invertebrates represent a large proportion of the biomass in aquatic ecosystems, particularly in the ocean. In recent years, invertebrates have been well-consolidated models in evolutionary developmental biology research and, consequently, genomic and transcriptomic sequence databases from a plethora of species across the animal kingdom have become available. This has provided an excellent source of evidence confirming that invertebrates operate endogenous mechanisms for PUFA production. The present paper reviews the current knowledge of gene complement and, where possible, the function of desaturases and elongases with pivotal roles in PUFA biosynthesis of aquatic invertebrates. More specifically, this review covers three major enzyme types, namely ωx desaturases, front-end desaturases and elongases, that have been characterised from species of sponges, cnidarians, molluscs, annelids, crustaceans, rotifers, echinoderms and non-vertebrate chordates (amphioxus and sea squirt). These studies have shown that invertebrates operate alternative and unusual pathways of PUFA biosynthesis involving gene families with complex phylogeny and functional diversity. Consequently, research in this area provides potentially valuable molecular tools in the form of genes that can be used in the biotechnological production of n-3 products.

“…The understanding of blunt snout bream lipid metabolism has improved with the cloning of genes such as FAS, CPT I and LPL (Li, Jiang, Qian, Xu, & Liu, ; Lu, Zhang, Wang, Xu, & Liu, ). The expression of these enzymes plays important roles in lipid metabolism, lipid decomposition, synthesis and transport (Li, Yuan et al., ; Peng et al., ; Shu‐Chien et al., ). Dietary lipid sources must be selected to promote both fish health and fish quality.…”

This study investigated the effects of dietary lipid sources on juvenile blunt snout bream, Megalobrama amblycephala. Juvenile blunt snout bream (14.40 ± 0.01 g) were fed diets containing 75 g/kg of fish oil (FO), linseed oil (LO), soybean oil, coconut oil (CO), rapeseed oil or beef tallow (BT) for 9 weeks. Survival rates, final weight, weight gain, feed efficiency ratio and feed intake remained unchanged. Viscerosomatic ratio, hepatosomatic index and condition factor were highest in fish fed the CO diet (p < 0.05). Whole‐body lipid content decreased, whereas liver lipid content increased in fish fed CO and BT diets (p < 0.05). Eicosapentaenoic acid and docosahexaenoic acid in the muscle and liver increased in fish fed the FO and LO diets (p < 0.05). FO and LO diets increased plasma glucose (p < 0.05). Feeding CO diet increased hepatic fatty acid synthase (FAS) and acetyl‐CoA carboxylase expression, and FAS activity (p < 0.05). Both CO and BT diets increased hepatic carnitine palmitoyltransferase I (CPT I) and carnitine palmitoyltransferase II expression, and CPT I activity compared to the FO diet (p < 0.05). These results indicate that LO can be substituted for FO in juvenile blunt snout bream diets without negative effects.

“…Most researches related to the effects of lipid sources on lipid metabolism have focused on fish such as Acanthopagrus schlegelii (Jin et al, 2017), Ctenopharyngodon idellus (Yu et al, 2018), Larmichthys crocea (Qiu et al, 2017), Oncorhynchus mykiss (Fickler et al, 2018), and Scophthalmus maximus L. (Peng et al, 2014). However, a few researches related to lipid metabolism have concentrated on crustaceans, such as Eriocheir sinensis (Wei et al, 2017; Liu et al, 2018), Litopenaeus vannamei (Chen et al, 2015b), and Sagmariasus verreauxi (Shu-Chien et al, 2017). Up to now, researches on this topic still limited.…”

“…Swimming crab ( Portunus trituberculatus ), one of the most important commercial mariculture crustacean species, is widely distributed in the coastal waters of China, Japan, Korea, and Malaysia (Jin et al, 2016). Over the past decade, researches on the effects of different dietary lipid sources on growth, tissue fatty acid compositions, immunity and antioxidant capacity and lipid metabolism in crustaceans have increased significantly (Ramesh and Balasubramanian, 2005; Zhou et al, 2007; Unnikrishnan et al, 2010; Hu et al, 2011; Li et al, 2011; Chen et al, 2015a; Han et al, 2015; Shu-Chien et al, 2017). However, researches related to the lipid and energy metabolism on crustaceans are still relatively few.…”

An 8-weeks feeding trial with swimming crab, Portunus trituberculatus , was conducted to investigate the effects of different dietary lipid sources on the lipid classes, lipid metabolism, and mitochondrial energy metabolism relevant genes expression. Six isonitrogenous and isolipidic experimental diets were formulated to contain fish oil (FO), krill oil (KO), palm oil (PO), rapeseed oil (RO), soybean oil (SO), and linseed oil (LO), respectively. A total of 270 swimming crab juveniles (initial weight 5.43 ± 0.03 g) were randomly divided into six diets with three replications, each consisted of 45 juvenile crabs. The results revealed that crabs fed KO had highest lipid content in hepatopancreas and free fatty acids in serum among all diets. The anabolic pathway relevant genes: fas and acc were up-regulated in KO diet. The catabolic pathway relevant genes, hsl , was up-regulated in LO diet, while cpt1 was up-regulated in KO diet. Whereas, the genes involved in the transport and uptake of fatty acids such as fabp1 and fatp4 were down-regulated in crab fed PO and RO diets. Furthermore, the gene expression levels of transcription factors: srebp-1 and hnf4 α in KO and SO diets were the highest among all diets. FO and KO diets had significantly higher unsaturation index of mitochondrial membrane than others. The genes related to mitochondrial energy metabolism, such as Atpase6 , sirt1 , and sirt3 were significantly up-regulated in KO and SO diets. In summary, dietary KO and SO supplementation could improve the lipid metabolism, promote energy production for juvenile swimming crab and improve physiological process and function including molting. These findings could contribute to deepen the understanding of the physiological metabolism of dietary fatty acids for swimming crab.
