“…Our data are in good agreement with those on bivalves (Pernet & Tremblay 2004, Pernet et al 2005) and marine finfish (e.g. Plante et al 2007 and references therein), where the proportions of 20:4n-6 in animals were higher than that in their diets. In gilthead seabream Sparus aurata, the incorporation of 20:4n-6 was most efficient when dietary 20:4n-6 was less than 2% of TFA while it dropped considerably at higher levels (Fountoulaki et al 2003).…”

This study examines the effects of varying dietary lipids on growth, survival, lipid composition and behaviour in lobster Homarus americanus (Milne Edwards, 1837) postlarvae. Lobsters were fed one of 3 diets during their early ontogeny: (1) Artemac, a widely used Artemia replacement; (2) a ternary mixture consisting of Artemac, frozen Artemia adults and Artemia flakes; or (3) a mixture of live A. salina nauplii and adults. We evaluated the olfactory capacity (response to predator odour plume) and cryptic behaviour (ability to hide during settlement) of lobster postlarvae as a function of these diets and the lipid and the fatty acid composition of lobsters. Growth and survival of lobster postlarvae were highest in those fed live Artemia, followed by the ternary mix, then Artemac. The low performance of lobster postlarvae fed Artemac may be attributable to dietary deficiencies in phospholipids (PLs) or 20:4n-6 and coincided with low levels of endogenous triacylglycerols (TAG). Those lobsters fed live Artemia showed low levels of 22:6n-3 and 20:5n-3 compared to levels occurring in wild animals. Here we report the selective incorporation of 20:4n-6, 20:5n-3 and 22:6n-3 to polar lipids and, to a lesser extent, to neutral lipids in lobsters. Finally, lobster postlarvae fed the 3 experimental diets responded to a predator odour plume by reducing their activity levels and increasing the time spent swimming downstream. However, lobster settlement behaviour varied as a function of the diet: low-performing lobsters fed Artemac were less active than those fed the other diets, presumably due to low levels of endogenous TAG or changes in dietary long-chain PUFA.

“…The DHA/EPA ratio is used as an indicator to select the optimum boosting strategy for larval feeds, as showed in a range of previous works (Estevez et al, 1999;Copeman et al, 2002;O'Brien-MacDonald;Plante et al, 2007;Hache and Plante, 2011). In the present trial, it was shown to be significantly higher in animals enriched with Diet A (1.31) rather than those fed on Diet B (0.42) and Diet C (absent), and was closer to the suitable 2/1 DHA/EPA ratio found in the natural food of a range of marine fish larvae (Sargent et al, 1997).…”

Secondary feeding with commercial lipids enrichments such as the microencapsulated diets Diet A (33.42±3.00%) and Diet B (55.88±3.5%) compared with the marine yeast type product Diet C(8.59±1.0%) as a method of increasing the total lipids and ω-3 PUFA content of rotifers, hence enhancing their nutritional value as live feed prey for fish larvae in hatcheries. The total lipids the rotifers was affected analogous to the levels of these components in the feeds showing its maximum percentage uptake within 4 hours from the enrichment (20.27±3.52, 26.64±3.91, 11.31±2.30 respectively). There was not any significant toxicity to the animals due to the diets during the 16 hours experiment. The DHA/EPA for Diet A(1.31), Diet B(0.42) and Diet C(absent) as well as the DHA/EPA/ARA ratios for Diet A(10.70 ± 1.60 / 8.18 ± 1.10 / 2.08 ± 0.20), Diet B(6.20 ± 2.30 / 14.60 ±1.00 / 1.12 ± 0.40) and Diet C (0 / 5.14 ± 3.40 / 1.30 ± 1.10) indicates that Diet A is closer to the suggested DHA/EPA/ARA optimal value 10/5/1 for marine fish larval growth.

“…It comes probably from the lipid emulsion used to enrich the Artemia nauplii, which naturally bioencapsulate substances and also contain large amounts of this fatty acid (Ladhar et al, 2014). This relative abundance of linolenic acid could be a problem, since marine fish larvae preferentially hydrolyze other fatty acids (Plante et al, 2007), with a limited ability to biosynthesize phospholipids (Sargent et al, 1999b). The control group also displayed an unbalanced ratio between PUFA's, with limited availability of DHA.…”

ABSTRACT. From early development until the completion of metamorphosis, fat snook (Centropomus parallelus) larvae are commonly fed the rotifers Brachionus spp. and Artemia spp. nauplii. In this study, cultivated copepods Acartia tonsa were evaluated as feed for 15-to 45-day-old larvae. Two experiments were performed using twelve 30-L tanks stocked with 3.3 fat snook larvae L -1. Their initial mean weight and length were 1.35 ± 0.01 mg (mean ± standard deviation) and 3.83 ± 0.33 mm for 15-day-old larvae and 2.79 ± 1.2 mg and 6.99 ± 0.88 mm for 31-day-old larvae. Three dietary treatments were carried out in four replicates, including Rotifer (R), Artemia (A) and/or Copepod (C). Experiment 1 included Diet RA (control), Diet RC and Diet RCA; while experiment 2 included Diet A (control), Diet C and Diet AC. The survival and growth of larvae fed the Diet RCA in experiment 1 were significantly higher than the others. In experiment 2, the inclusion of copepods in the diet did not improve survival and growth, however, larvae fed Diet C had the highest DHA/EPA ratio. We conclude that the copepod Acartia tonsa provides an important nutritional benefit to fat snook larvae undergoing metamorphosis.
