“…Although the yolk sac ensures the endogenous nutritional storage during the initial life stages (Mazorra et al, 2003), little is known about the influence of maternal nutrition on growth of post-larvae when they no longer depend on their endogenous reserves. Ng & Wang (2011) verified that the utilization of crude palm oil in the diet of tilapia broodstock influenced the gonadal development, egg production, hatchability and larval normality.…”

-This study was carried out to evaluate the influence of different levels of digestible energy and digestible protein in diets of Nile tilapia (Oreochromis niloticus) broodstock on offspring growth during sex reversal stage. A total of 2,700 post-larvae (8.2±0.001 mg) derived from breeders fed nine diets with distinct levels of digestible protein (28, 34 and 40% DP) and digestible energy (2,800; 3,400; and 4,000 kcal DE.kg -1 ) were stored in twenty-seven 70 L tanks. After 30 days of growth, their average final weight (AFW, g), average weight gain (AWG, g), final standard length (SL, cm), condition factor (CF), specific growth rate (SGR, %/day), stock uniformity (UNI, %), survival (SUR, %) and sex reversal rate (SRR, %) were measured. Although female nutrition is thought to influence the performance or quality of progeny during early life stages, no influence of diets supplied to broodstock was detected on any parameter. Nonetheless, the offspring presented commercially satisfactory growth rates. Thus, diets containing 28% of digestible protein and 2,800 kcal of digestible energy.kg of diet -1 can be used to feed Nile tilapia broodstock without jeopardizing offspring performance during the sex reversal phase.

“…Effects of ARA on fecundity and egg and larval quality in teleost fish, including cod, have been well documented (e.g. Bruce et al, 1999;Furuita et al, 2003;Lund et al, 2008;Mazorra et al, 2003;Pickova et al, 2007Pickova et al, , 1997Røjbek et al, 2014;Salze et al, 2005). Furthermore, a number of studies have documented in vitro effects of ARA and other fatty acids on steroidogenesis and follicular maturation in fish (Knight and Van der Kraak, 2015;Van der Kraak, 2008, 2009;Van Der Kraak, 1995, 1996;Patino et al, 2003;Sorbera et al, 2001;Van Der Kraak and Chang, 1990;Wade et al, 1994).…”

“…Studies on broodstock nutrition in cod, as well as other fish species, generally focus on the effect of diet on fecundity, egg and larval viability and biochemical composition of the eggs (Lie et al, 1993;Silversand et al, 1995;Røjbek et al, 2014;Hemre et al, 1995;Mangor-Jensen et al, 1994;Pickova et al, 1997;Salze et al, 2005;Izquierdo et al, 2001;Furuita et al, 2003;Mazorra et al, 2003;Lanes et al, 2012). The essential, highly unsaturated fatty acids (HUFA) arachidonic acid (ARA; 20:4n-6), eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 20:6n-3) have received special attention (cf.…”

“…A diet supplemented with ARA concentrations higher than those obtained with northern hemisphere fish oils, can increase fecundity, egg quality and viability of larvae in marine teleosts such as European sea bass (Dicentrarchus labrax), Japanese flounder (Paralichthys olivaceus), Atlantic halibut (Hippoglossus hippoglossus) and Atlantic cod (Bruce et al, 1999;Furuita et al, 2003;Mazorra et al, 2003;Røjbek et al, 2014). ARA is the precursor of biologically active eicosanoids, such as prostaglandins and leukotrienes, that are involved in many aspects of reproduction (e.g.…”

a b s t r a c tThe present study was designed to investigate potential effects of arachidonic acid (ARA) on the reproductive physiology of female Atlantic cod (Gadus morhua L.).Two-year old Atlantic cod of both sexes were equally distributed into eight sea cages after completion of their first spawning in May 2005. Four experimental groups were established and fed diets with different levels of ARA corresponding to 0.5, 1, 2 and 4% of total fatty acid. Ovarian growth and development was documented every month. Fatty acid composition was analysed in ovaries, liver and plasma at the beginning of the experiment, one month prior to spawning, and in spent fish, one month after spawning was completed. Plasma concentrations of estradiol-17b, testosterone and vitellogenin, and ovarian gene transcript levels of steroidogenic acute regulatory protein (star), P450aromatase (cyp19a1a) and 20b-hydroxy steroid dehydrogenase (20bhsd/cbr1) were monitored every month in fish fed the experimental diets and related to oocyte stage. Potential fecundity was calculated based on ovarian samples taken one month before onset of spawning.Ovarian and plasma ARA levels were highly correlated to dietary ARA levels. There was a net accumulation of ARA compared to other essential fatty acids in ovarian tissue that was reflected in a decrease in EPA:ARA ratio. Plasma concentrations of vitellogenin, estradiol-17b and testosterone and key gene transcript levels were affected by dietary ARA and stage of maturation. The results show that ARA has a significant influence on the reproductive physiology of female Atlantic cod.

“…EPA and DHA are also essential fatty acids for marine fish. The inclusion of the two fatty acids in fish diets are known to improve the quality of broodstocks, and the growth and normal development of larvae (Watanabe, 1993;Furuita et al, 2000;Takeuchi, 2001;Copeman et al, 2002;Watanabe & Vassallo-Agius, 2003;Mazorra et al, 2003). Moreover, HUFA have been shown to promote tolerance to handling stress (Koven et al, 2001), increase cellular (Wu et al, 2003), and humoral (Kiron et al, 1995) defense responses and offer disease resistance (Kiron et al, 1995).…”

Over-Expression of Gene Encoding Fatty Acid Metabolic Enzymes in Fish

Eicosapentaenoic acid (EPA, and docosahexaenoic acid (DHA, 22:6n-3) have important nutritional benefits in humans. EPA and DHA are mainly derived from fish, but the decline in the stocks of major marine capture fishes could result in these fatty acids being consumed less. Farmed fish could serve as promising sources of EPA and DHA, but they need these fatty acids in their diets. Generation of fish strains that are capable of synthesizing enough amounts of EPA/DHA from the conversion of α-linolenic acid (LNA, 18:3n-3) rich oils can supply a new EPA/DHA source. This may be achieved by over-expression of genes encoding enzymes involved in HUFA biosynthesis. In aquaculture, the successful of this technique would open the possibility to reduce the enrichment of live food with fish oils for marine fish larvae, and to completely substitute fish oils with plant oils without reducing the quality of flesh in terms of EPA and DHA contents. Here, three genes, i.e. Δ6-desaturase-like (OmΔ6FAD), Δ5-desaturase-like (OmΔ5FAD) and elongase-like (MELO) encoding EPA/ DHA metabolic enzymes derived from masu salmon (Oncorhynchus masou) were individually transferred into zebrafish (Danio rerio) as a model to increase its ability for synthesizing EPA and DHA. Fatty acid analysis showed that EPA content in whole body of the second transgenic fish generation over-expressing OmΔ6FAD gene was 1.4 fold and that of DHA was 2.1 fold higher (P<0.05) than those in non-transgenic fish. The EPA content in whole body of transgenic fish over-expressing OmΔ5FAD gene was 1.21-fold, and that of DHA was 1.24-fold higher (P<0.05) than those in nontransgenic fish. The same patterns were obtained in transgenic fish over-expressing MELO gene. EPA content was increased by 1.30-fold and DHA content by 1.33-fold higher (P<0.05) than those in non-transgenic fish. The results of studies demonstrated that fatty acid content of fish can be enhanced by over-expressing gene encoding enzymes involved in fatty acid biosynthesis, and perhaps this could be applied to tailor farmed fish as even better sources of valuable human food.
