Differences in egg quality between wild striped trumpeter (Latris lineata) and captive striped trumpeter that were fed different diets.

摘要: Abstract This study assessed differences in egg quality between freshly caught striped trumpeter, Latris lineata , and captive trumpeter that were fed either chopped fish or commercial salmon pellets. Total lipid content of eggs did not differ the three groups (average 20% dry weight). The group produced with greatest docosahexaenoic acid (DHA)/eicosapentaenoic (EPA) ratio (4:1) and, together collected from wild group, contained highest ( n −3)/( −6) polyunsaturated fatty acids (PUFAs) (9:1 8:1, respectively). Ascorbic levels pellet-fed (75 μg g −1 wet weight) higher than chopped-fish (48 40 weight, respectively), but there was no difference α-tocopherol 4.4 volume produced, fertilisation rate length larvae at hatch differ, greater diameter, which corresponded to a larger yolk volume, hatching success group. Each broodstock viable yolk-sac larvae, relatively low DHA/EPA ratios suggest this diet may be inferior, when compared fish, for sustained growth survival.
