“…Large yellow croaker, Larimichthys crocea , is an important carnivorous marine fish species that is being widely cultured in southeast China. Recently, low retention of n‐3 LC‐PUFA has been observed after large proportion of fish oil was replaced by vegetable oil, which seriously affected fillet quality (Duan, Mai, Shentu, Ai, Zhong, Jiang, Zhang, Zhang & Guo ). This was largely attributed to their less capacity to biosynthesize LC‐PUFA from linolenic acid (18:3n‐3, LNA) and linoleic acid (18:2n‐6, LA) compared with the fresh water counterparts (Ghioni, Tocher, Bell, Dick & Sargent ; Torstensen, Bell, Rosenlund, Henderson, Graff & Tocher ).…”

In this study, the full‐length cDNA of fatty acyl elovl5‐like elongase was first cloned from large yellow croaker, Larimichthys crocea. The cDNA of elovl5‐like was 1551 bp, including a 5′‐terminal untranslated region (UTR) of 120 bp, a 3′‐terminal UTR of 546 bp and an open reading frame (ORF) of 885 bp encoding a polypeptide of 294 amino acid residues. Sequence comparison showed that the predicted protein revealed a high percentage identity (>80%) with Elovl5 from other marine fish species. Tissue distribution analysis revealed that the elovl5‐like was expressed highly in liver, brain and gill, and at much lower levels in stomach, intestine, heart and spleen. Quantity polymerase chain reaction showed that hepatic elovl5‐like transcription decreased significantly with the increase in dietary n‐3LC‐PUFA (P < 0.05). The mRNA levels of elovl5‐like in the liver of fish fed diets with 0.15%, 0.60% and 0.98% n‐3LC‐PUFA were up‐regulated by 1.77‐fold, 1.41‐fold and 1.41‐fold than that with 2.25% n‐3LC‐PUFA respectively. No significant differences were observed in the hepatic mRNA levels of elovl5‐like in response to the increased ratio of dietary DHA/EPA (P > 0.05). These results demonstrate for the first time the presence and nutritional modulation of elovl5‐like cDNA in large yellow croaker. This could contribute to better understanding the process of n‐3LC‐PUFA biosynthesis in this fish species.

In this study, the full-length cDNA of a D6-fatty acyl desaturase-like (D6-Fad-like) enzyme was first cloned from large yellow croaker, Larmichthys crocea. The cDNA was 2049 bp, with a 107 bp 5 0 -UTR, a 604 bp 3 0 -UTR, and an ORF of 1338 that specified a protein of 445 amino acids. It contains two membrane-spanning domains, three histidine-rich regions and a cytochrome b 5 domain, which all align perfectly with the same domains located in other recently identified vertebrate D5 and D6 desaturases. Sequence comparison showed that the predicted protein revealed a high percentage identity (>70%) with D6 desaturases from other marine fish species. Tissue distribution analysis revealed that D6-Fad-like was expressed at highest level in brain, much lower level in liver and gill, and lowest level in spleen, heart, stomach and intestine. The hepatic mRNA levels of D6-Fadlike showed statistically negative relationship relative to increasing dietary n-3LC-PUFA and DHA/ EPA (P < 0.05, R > 0.6). Transcription of D6-Fadlike in liver of fish fed diets with low and moderate level of n-3LC-PUFA (0.15%, 0.60% and 0.98% dry diet) was significantly increased by more than 20-fold than that with higher n-3LC-PUFA (1.37%, 1.79% and 2.25% dry diet; P < 0.05). The transcriptional levels of D6-Fad-like in the liver of fish fed diets with the ratio of 0.61, 1.54 and 2.17 (DHA/EPA) were significantly up-regulated by about 46-fold, 4.8-fold, and 1.2-fold compared with that in the control group (DHA/ EPA = 3.88) respectively (P < 0.05). This could contribute to better understanding the process of n-3LC-PUFA biosynthesis in this fish species.

“…Large yellow croaker ( Larmichthys crocea , Richardson) of 245 g average initial weight were fed for 12 weeks on diets formulated to partially or completely replace FO with soybean or palm oils (Duan et al . ). Trends in fish growth rates were inconsistent with the source or the inclusion level of dietary lipid.…”

Marine tropical carnivorous (MTC) fish are less tolerant to high dietary lipid compared with cold and temperate climate fish. However, insufficient n-3 longchain (≥C 20 ) polyunsaturated fatty acids (LC-PUFA) compromises MTC fish health and growth which requires attention when choosing lipid sources in aquafeed formulations. Fish oil (FO) has been the major lipid source for feeding key MTC fish. We estimated that more than 200 thousand tonnes of FO were used to feed farmed MTC fish in 2016, representing nearly 25% of global FO production. Nevertheless, recent increases in FO prices and demand, and the foreseen inability of wild fisheries to produce sufficient FO in the future, have created a need for cheaper and more sustainable alternatives. Meta-analysis showed that feeding vegetable oils (VO) to MTC fish can slightly reduce their growth, with a marked decrease in n-3 LC-PUFA content in the fish tissues corresponding with the increased replacement of FO and fishmeal in the diet. Rendered terrestrial animal fat or modulating the bioconversion of n-3 LC-PUFA precursors in VO can be utilised further in MTC fish nutrition with more research recommended on these approaches. Oils and oil-rich meals from non-food marine organisms are rich in n-3 LC-PUFA and represent an underutilised alternative to FO for tropical aquaculture. With oils rich in n-3 LC-PUFA produced from transgenic plants presently gaining regulatory approvals and becoming available as a renewable alternative to FO, aquaculture in the tropics and around the globe is ready to leap into a new phase of sustainable expansion.
