“…Fernández-Palacios et al (1995) observed poor hatching rates and survival in sea bream, linked to low fatty acid content. Also, Furuita et al (2002Furuita et al ( , 2003 observed the same thing in Japanese flounder. In marine fish, EPA and, especially, DHA are regarded as EFAs due to their necessity for good growth.…”

Two groups of Anguilla japonica were treated with hormone, one on a weekly basis, the other on a biweekly basis. Intramuscular injection was applied at a dose of 0.75 mg/kg BW carp pituitary extract (CPE) plus 150 IU/kg BW human chorionic gonadotropin (hCG) for female fish, while males received half of this dose. The average total lipid content of the gonads from the weekly treated group, i.e. 20.6 ± 1.2 % for females and 18.0 ± 2.3 % for males, was significantly higher than the biweekly treated group, 16.8 ± 0.7 and 15.5 ± 1.3 %, respectively (p \ 0.05). For both muscle and liver, the readings were not significantly different. The gonads from the weekly treated fish had more fatty acids, particularly saturated fatty acids, polyunsaturated fatty acids, highly unsaturated fatty acids, eicosapentaenoic acid (20:5n-3, EPA), docosahexaenoic acid (22:6n-3, DHA) and arachidonic acid (20:4n-6, ARA). Histological examination showed that the ovaries of both the weekly and the biweekly treated fish were mainly at stage IV. However, the weekly treated females had bigger oocyte diameter (722.0 ± 60.9 lm) than the biweekly females (611.6 ± 22.6 lm). These results suggest that CPE and hCG promoted the maturation process for both scheduled induction and that the frequency of hormone injection influenced the biochemical composition of gonads, especially their lipids. Our study describes for the first time the effect of hormone injection frequency on the lipid content and fatty acid composition in the gonads of A. japonica during artificial maturation.

“…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.

“…In PL and NL, ARA was the most abundant n-6 PUFA (ranged from 2.59 to 11.33 % and from 0.16 to 3.19%, respectively). ARA is always found more in PL than NL of all the tissues, probably due to its functionality in cell membrane (Alexis and Nengas, 1996;Bessonart et al, 1999;Fountoulaki et al, 2003;Furuita et al, 2003). 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).…”

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.
