“…The 18-carbon PUFAs were incorporated into the ovum PL of flax-oilfed broodstock in a manner similar to that previously reported (Lewis et al 2010). Although 18:3(n-3) was the predominant 18-carbon PUFA found in the experimental diets, this FA was largely excluded from ovum PL and was deposited within the CWE and TAG fractions.…”

“…Unfertilized ova were collected, and a subsample was frozen immediately and stored at −80 • C for later FA analysis. Remaining ova from each female were fertilized and incubated in individual MacDonald jars as described by Lewis et al (2010). At 2 h postfertilization, fecundity estimates for each female were determined volumetrically as described by Lane and Kohler (2006).…”

“…Previously, the dietary n-3 LC-PUFA requirements for female broodstock of white bass Morone chrysops were found to range from 3.9% to 4.0% dry matter (Lane and Kohler 2006;Lewis et al 2010). To achieve this n-3 LC-PUFA inclusion level in previous practical diet formulations, dietary lipid was provided via 100% menhaden (Brevoortia spp.)…”

“…fish oil in combination with full-fat menhaden meal. However, both Lane and Kohler (2006) and Lewis et al (2010) utilized a lipid source that was rich in 18:2(n-6) as an alternative to dietary fish oil (in FA notation, the number of carbon atoms is presented to the left of the colon, the number of double bonds is immediately to the right of the colon, and the position of the first double bond from the methyl end is given after the hyphen). The enzymes responsible for PL synthesis have an affinity for 18:2(n-6) relative to other 18-carbon PUFAs (Lands 2000).…”

“…The enzymes responsible for PL synthesis have an affinity for 18:2(n-6) relative to other 18-carbon PUFAs (Lands 2000). When broodstock are fed 18:2(n-6)-rich lipid sources, ovum PL can become disproportionately enriched with this FA (Lewis et al 2010), thereby displacing other FAs that are critical to development (i.e., LC-PUFAs). For example, hatch rate and larval survival to 3 d posthatch declined in response to increasing concentrations of 18:2(n-6) and decreasing concentrations of 20:5(n-3) and 22:6(n-3) in diets for female white bass broodstock (H. A.…”

Differential Incorporation of Dietary Fatty Acids from Flax and Fish Oils into Lipid Classes of White Bass Ova

The extent to which flax oil can replace fish oil in diets fed to female broodstock of white bass Morone chrysops was determined by evaluating growth performance and the fatty acid (FA) profile of ovum lipid classes. Four experimental diets containing increasing levels of flax oil as 0, 33, 67, and 100% replacement of menhaden (Brevoortia spp.) fish oil were fed to female white bass for 30 weeks prior to spawning. Overall, growth and survival were unaffected when flax oil replaced fish oil in the diets. However, ovum FA composition did differ by lipid class and according to dietary intake. The FA profile of the neutral lipid classes largely resembled dietary intake, resulting in monounsaturated FAs (MUFAs) and long‐chain polyunsaturated FAs (LC‐PUFAs; FAs with ≥20 carbons and ≥3 double bonds) as the most predominant FAs found within ova produced by 100% fish‐oil‐fed broodstock, while MUFAs and 18‐carbon PUFAs dominated the ovum neutral lipid in females from the 100% flax oil treatment. Although the phospholipid fraction of ova produced by the 100% flax‐oil‐fed broodstock was also significantly enriched with 18‐carbon PUFAs, accumulation of these FAs did not displace n‐3 LC‐PUFAs as comparable levels of n‐3 LC‐PUFAs were found in both the 100% fish oil and 100% flax oil treatments. Overall, flax oil has potential for use as an alternative to menhaden fish oil in diets for female white bass broodstock without altering phospholipid LC‐PUFA content. However, further investigation is needed to determine how these modifications to ovum FA profile affect embryonic and larval survival.Received January 19, 2010; accepted August 17, 2010

We evaluated the fatty acid (FA) composition of broodstock white bass ova fed one of six commercial diets with increasing polyunsaturated FA content (n-6/n-3 ratio; 0.36, 0.39, 0.46, 0.83, 1.07, 1.12) eight weeks prior to sampling. Fatty acid profiles of ova from brooders fed each of the six diets were significantly altered according to canonical discriminant analysis. Ova FA profiles resulting from the 0.39 diet separated those from the 0.36 diet based on lower 18:2n-6 (LNA) and higher 20:1n-9 concentrations from the 0.36 diet. Ova profiles were further separated based on lower concentrations of 22:5n-3 (DPA) from the 0.46 diet, lower concentrations of 20:5n-3 (EPA) in the 1.12 and 0.83 diets, and lower concentrations of 22:6n-3 (DHA) in all other diets relative to the 0.46 diet. Changes in ova FA profile at four and eight weeks were consistent with dietary intake with an approximate 2% increase in any given FA class with increasing time on individual diet. There was no correlation between dietary ARA concentrations (0.7-1.1 mol%), or dietary EPA/ARA ratios (7-15), and the concentrations (1.4-1.7 mol%) or ratios (3.3-4.4) found in the ova by diet. Our results suggest that white bass females have the ability to preferentially incorporate n-3 PUFA, particularly DHA, suggesting mobilization of this FA from other tissues for ova deposition or preferential dietary incorporation of PUFA into ova. These results will add to the limited FA information available in white bass and enable nutritionists to formulate broodstock diets that maximize reproductive potential in this species.
