“…Also in agreement with the present study, a range of larval and juvenile marine species such as Atlantic cod Gadus morhua , gilthead sea bream Sparus aurata (Alves Martins et al, 2012;Atalah et al, 2011a;Fountoulaki et al, 2003), Senegalese sole (Villalta et al, 2005) and turbot (Estévez et al, 1999), were able tolerate a wide range of dietary ARA levels with growth and survival found to be independent of ARA inclusion. In agreement, several recent studies have further demonstrated that balanced ARA and EPA are more critical than either individual FA in terms of growth and other metabolic processes further highlighting the need for understanding the optimal LC-PUFA balance (Norambuena et al, 2015;Norambuena et al, 2016).…”

“…While several studies have investigated the effect of dietary ARA on the performance of marine larvae (Estevez et al 1997;Bessonart et al 1999;Harel et al 2001;Koven et al 2001bKoven et al , 2003Villalta et al 2005), and most postulate that eicosanoids may be responsible for a range of physiological changes, few studies have actually quantified prostanoids. Logue et al (2000) investigated the effect of dietary n-3 PUFA on total Table 3 for replication.…”

“…Similarly, a positive relationship between dietary ARA and resistance to a hypersaline challenge in the larval flatfish, summer flounder (Paralichthys dentatus), has also been identified (Willey et al 2003). Conversely, malpigmentation in several larval flatfish species has been associated with increasing dietary ARA, and the ratio between ARA and EPA Villalta et al 2005). Tissue ARA/EPA ratios and their influence on the production of eicosanoids appear to be an important consideration in larval fish studies.…”

We determined the effect of dietary arachidonic acid (20:4n-6, ARA) on tissue ratios of ARA/eicosapentaenoic acid (20:5n-3, EPA) and subsequent whole body production of the eicosanoids, prostaglandin F 2a (PGF 2a ) and E 2 (PGE 2 ) in the marine larvae of striped trumpeter, Latris lineata. Larvae were also subjected to a hypersaline challenge (55 ppt) with an aim to determine possible relationships between tissue fatty acid profiles, prostanoid production, and their tolerance to osmotic challenge. From 5 to 23 days post-hatch (dph) larvae were fed live food, rotifers (Brachionus plicatilis), that had been enriched with one of five experimental emulsions containing increasing concentrations of ARA and constant EPA and 22:6n-3 (docosahexaenoic acid, DHA). Final ARA concentrations in the rotifers were 1.33, 3.57, 6.21, 8.21 and 11.22 mg g )1 DM. Larval growth and survival was unaffected by dietary ARA. Tissue fatty acid concentrations generally corresponded with dietary fatty acids and final tissue ratios of ARA/EPA ranged from 0.9 to 4.9. At 18 and 23 dph whole body concentrations of PGF 2a and PGE 2 generally increased as more dietary ARA was provided in a dose-response manner, and a significant elevation in both PGF 2a and PGE 2 in larvae fed the highest dietary ARA concentration was recorded at 23 dph compared to larvae receiving the lowest concentration. At 18 dph, the highest cumulative inactivity following a hypersaline challenge occurred in larvae fed 8.21 or 11.22 mg ARA g )1 DM, which was significantly greater than those receiving 3.57 mg ARA g )1 DM. At 23 dph no relationship between inactivity of larvae subjected to a hypersaline challenge to dietary ARA was evident. In summary, dietary ARA altered tissue ARA/EPA ratios, prostanoid production and resistance to a hypersaline challenge in larval striped trumpeter. While increasing dietary ARA generally resulted in elevation of prostanoids as well as increasing the number of inactive larvae following a hypersaline challenge at 18 dph, similar trends between prostanoids and larval inactivity were not evident at 23 dph, suggesting the exact mechanisms and relationships between eicosanoids and larval osmoregulation warrants further investigation. Nevertheless the study provides preliminary data on the effect of dietary ARA on the prostaglandin production in marine fish larvae.

Changing environmental conditions in the North Pacific are altering the lipid/fatty acid (FA) composition of zooplankton assemblages, but the consequences to resident fish larvae are unknown. In the laboratory, we reared Pacific cod Gadus macrocephalus larvae over 4 wk on prey enriched with varying levels of 2 essential FAs (docosahexaenoic acid, DHA, 22:6ω-3, and eicosapentanoic acid, EPA, 20:5ω-3) to determine how this species responded to such changes in prey quality. Ratios of DHA:EPA were chosen to represent the natural variation observed in zooplankton of the North Pacific. We tested the hypotheses whether (1) energetically similar diets comprised of varying levels of DHA and EPA affect growth and survival in Pacific cod larvae, and (2) the highest levels of DHA:EPA (2:1) are optimal for Pacific cod larvae, as it has been shown for Atlantic species. Pacific cod larvae grew fastest with diets containing high levels of ω-3 polyunsaturated fatty acids (PUFA > 22%). Diets with the same total lipid content but different DHA:EPA ratios (< 0.1:1 to 2:1) also mediated growth and lipid composition of the larvae. Unlike Atlantic cod, Pacific cod larvae did not show as high a requirement for DHA relative to EPA but rather achieved largest size-at-age with intermediate DHA:EPA ratios (0.8:1 to 1.1:1). This range most closely resembled DHA:EPA ratios reported from North Pacific copepods, suggesting anomalous years with an over-or under-abundance of DHA-rich dinoflagellates or EPA-rich diatoms may be detrimental to survival and growth of Pacific cod larvae in the field.
