“…les converted this into poly-unsaturated fatty acids including EPA and DHA, stored primarily in the gonads and oocytes. Anido et al (2015) reported a higher quantity of EPA (2.3%) and DHA (7.3%) observed in mature ovaries of wild R. quelen than those observed in this study. Despite low levels of linoleic acid in palm oil diets, females of this group appeared to efficiently convert it to ARA, as the quantity of this fatty acid in ovary and oocytes was similar to that of females fed soybean oil.…”

The effects of a diet supplemented with 5% marine fish oil, 5% refined palm oil, 5% soybean oil, and a combination of the three on reproductive parameters of females Rhamdia quelen was investigated. Spawning was artificially induced to evaluate rates of fertilization, hatching and larvae normality. Fatty acid profiles of the diets, ovaries and oocytes were determined. A higher spawning rate (%) was observed for diets containing fish oil (78.65 ± 3.60) and palm oil (77.15 ± 3.97), followed by oil mix (65.46 ± 4.57). The diet containing soybean oil was associated with significantly lower fertilization (60.14 ± 5.66; P < 0.05) than the palm and fish oil diets. Lower fertilization may be explained by a high level of n-6 fatty acids in the diet, which possibly accelerate the oocyte maturation. Satisfactory fecundity (P > 0.05) were observed for all tested diets, whit 289.77 ± 23.90 (palm oil) until 323.31 ± 38.45 oocytes g-1 body weight (fish oil). The treatments were not shown to influence oocyte size, larval size or rate of larva deformity. Oocyte fatty acid composition was like that of gonads. Docosahexaenoic (DHA; C22:6 n-3) fatty acid was preferentially deposited in ovaries and oocytes. Ratios of n3/n6, DHA/EPA, EPA/ARA, did not affect the reproductive performance of females. Therefore, regarding female reproductive performance, the vegetable lipid sources tested are suitable for being used in R. quelen diet, and palm oil, in particular, is considered an excellent alternative to fish oil.

“…Arachidonic acid (ARA, C20:4n6), eicosapentaenoic acid (EPA, C20:5n3), docosahexaenoic acid (DHA, C22:6n3) are among the derived omega-6 and omega-3 long chain of HUFA (n-3 and n-6 LC PUFA; C ≥ 20). The consumption of diet containing EPA and DHA help to optimize animal growth [80] while ARA functions as the precursor for eicosanoids that regulates reproductive success and sexual behaviour of females [81]. In general, EPA and DHA can be obtained from the consumption of plant materials or through series of elongation and desaturation of α-linolenic acid (ALA, C18:3n3).…”

There are several literatures that cover different views of crustacean food, feeding and behavior aspects, but little was known on its interaction between them and it's also shown a different perspective. Thus, a better understanding of the interactions between food, feeding and diets in crustaceans is vital for developing better quality of seed or broodstock produced in hatchery and its adaptation to the aquaculture environment and system. The aim of the present review is to update the state of the art and to explicit the knowledge regarding food, feeding and diets in crustaceans and challenges and opportunities in the development of formulated diets.

Chinese sturgeon (Acipenser sinensis) with an evolutionary history of over 200 million years, has a long lifespan, and an extremely late and asynchronous sexual maturation (8–18 years for males and 14–26 years for females), resulting in the difficulty of mature adult culture. However, little is known about the regulatory mechanisms of the transition among ovarian maturation stages in the Chinese sturgeon. We performed de novo transcriptome sequencing of the Chinese sturgeon at different ovarian maturation stages (FII, FIII, and FIV). The number of differentially expressed genes (DEGs) between FII and FIII/FIV (33,517/34,217) was more than that between FIII and FIV (22,123), suggesting that the transition from FII to FIII/FIV is more important than that from FIII to FIV for ovarian maturation. The number of upregulated genes was more than that of the downregulated genes, suggesting that increased gene expression was involved in the transition from FII to FIII/FIV. The representative pathways of DEGs were steroid biosynthesis, fatty acid biosynthesis, fatty acid elongation, glycerolipid metabolism, biosynthesis of unsaturated fatty acid, and α‐linolenic acid metabolism. The differential expressions from the transcriptome sequencing were validated with real‐time reverse‐transcription polymerase chain reaction. We also found 13 genes in sexual development, female sex determination, gonadal development, ovarian maturation, ovarian follicle development, and oocyte development pathways, which were differently expressed among fish at FII, FIII, and FIV. We suggest that enhanced synthesis of steroid, unsaturated fatty acid, and α‐linolenic acid may contribute to ovarian maturation of the Chinese sturgeon. These potential determinants provide a glimpse of the molecular architecture of ovary development in sturgeons.
