“…In the individuals that received commercial diets, reproductive performance was impaired even after addition of fish oil enriched with n-3 fatty acids. In a subsequent study on sea bass broodstock nutrition, addition of tuna orbital oil, which is high in DHA, and in ARA in particular, to the diet significantly improved egg survival and hatching (Bruce et al, 1999). Bogevik et al (2014) found that feeding male sea bass a diet with a high content of plant oil resulted in delayed sexual maturation and suppression of maturation-related gene expression, compared to fish fed a diet based on marine oil.…”

“…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).…”

“…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.

“…When formulated for the broodstocks under captivity system, the ARA/EPA ratio may be controlled by the LN/LNA ratio in the feeds. Some studies have pointed out the physiological importance of maintaining correct proportions of EPA, ARA and DHA fatty acid in the phospholipids of the cell membrane bilayer (Bruce et al, 1999;Sargent et al, 1999). According to these studies, which have defined the critical role played by eicosanoids in numerous physiological functions, the possible interactions between their precursors, like ARA and EPA, support the hypothesis that a suitable ARA, EPA and DHA profile in the diet must be supplied.…”

“…ARA has similar biologically importance as EPA and DHA and considered as the precursor of several eicosanoids which are produced by the ovarian tissues and play an important role in the ovulation process (Venkatesh et al, 1992;Knight et al, 1995;Goetz et al, 1987;Murdoch et al, 1993;Suloma and Ogata, 2011) and cholesterol accumulation in tissues (Norambuena et al, 2012). However, EPA plays an important role in the function of eicosanoids derived from ARA as it competes with the enzyme systems producing eicosanoids from ARA, thus exerting a modulating influence over the quantity and efficacy of ARA-derived eicosanoids (Bruce et al, 1999).…”

Fatty acids compositions were analyzed in neutral lipids (NL) and polar lipid (PL) of gonads of Nile tilapia, ayungin and African catfish to elucidate some guesses for the fatty acids requirements for broodstock. The high value detected for both C16:0, C18:1 n-9 in all samples reflects a requirement for energy metabolism during the course of gonad development. The Lower proportion of polyunsaturated fatty acids (PUFA) was found in the NL of all gonads samples compared to PL. The higher percentages of n-3 HUFA in PL with respect to NL, suggests the importance of HUFA in the reproductive processes. In PL and NL, arachidonic acid (ARA) was the most abundant n-6 PUFA (ranged from 2.59 to 11.33% and from 0.16 to 3.19%, respectively). A relatively higher particularly eicosapentaenoic acid (EPA)/ docosahexaenoic acid (DHA) ratio was obtained in both NL and PL. All wild species studied are characterized by high ARA/EPA ratio in PL ranged from 1.72 to 5.47. Therefore, it is necessary to take into consideration not only the individual levels of HUFA but also the correct ratio among them (ARA/EPA/ DHA) through controlling LA and LNA level and ratio in the diets of tropical freshwater broodstocks.
