“…Consequently, the energetic value corresponding to lipids of BFT and bonito eggs is 1.9 cal/mg dry mass, which is 26.4% of the total caloric value of the egg. Compared to the values obtained in our study, data published to date report higher egg total lipid content values for cultured fish species, such as European sea bass (Devauchelle and Coves 1988), gilthead sea bream (Mourente and Odriozola 1990;Almansa et al 1999), common dentex (Mourente et al 1999), and cobia (Faulk and Holt 2008), or lower values, as in Senegal sole eggs (Vázquez et al 1994;Mourente and Vazquez 1996). It is also well documented that egg TL content may vary depending on the broodstock diet and/or the period of the spawning season (Devauchelle and Coves 1988;Mourente and Odriozola 1990;McEvoy et al 1993;Sargent 1995;Evans et al 1996).…”

“…They are also very similar to those of eggs from other cultured teleost fish species, such as red sea bream , European sea bass (Devauchelle and Coves 1988), gilthead sea bream (Almansa et al 1999), common dentex (Mourente et al 1999), and white sea bream (Cejas et al 2004), all containing a single oil globule, and higher than eggs of cultured Senegal sole, which contain multi-globules (Vázquez et al 1994;Mourente and Vazquez 1996).…”

Lipids and essential fatty acids are determinants of the reproductive process in marine fish, affecting fecundity, egg quality, hatching performance, pigmentation and larval malformation. We have analyzed and characterized the lipids of eggs and unfed larvae of two wild caught scombroid fish, the Atlantic northern bluefin tuna (Thunnus thynnus) and Atlantic bonito (Sarda sarda). Dry matter and total lipid contents, polar and neutral lipid classes and total lipid fatty acid contents were determined in the eggs of bluefin tuna and eggs and unfed larvae during the development of Atlantic bonito. Bluefin tuna eggs had slightly but significantly more dry mass than bonito eggs but very similar lipid content. However, bluefin tuna eggs presented a higher polar lipid content due to increased proportions of phosphatidylethanolamine (PE), phosphatidylserine (PS) and phosphatidylinositol (PI). Bonito eggs and larvae showed increasing dry mass and decreasing lipid content with development. The proportion of polar lipids increased due to increased PE, PS and PI, whereas choline-containing polar lipids (phosphatidylcholine and sphingomyelin) remained relatively constant. Free cholesterol also increased, whereas the levels of other neutral lipids, especially triacylglycerol and steryl ester fractions, decreased, presumably due to utilization for energy to drive development. Bluefin tuna eggs had higher levels of n - 3 and n - 6 highly unsaturated fatty acids due to higher docosahexaenoic and arachidonic acid contents, respectively, than bonito eggs. The results are discussed in relation to the lipid and fatty acid requirements of larval scombroid fish in comparison to those of other larval marine finfish species under culture conditions.

“…In European sea bass (Dicentrarchus labrax), maximum cathepsin B activity occurs at the morula stage (Carnevali et al, 2001), which may be a consequence of the different development rates of these embryos when compared with those of F. heteroclitus (e.g. European sea bass embryos hatch at about 2 dpf at 16-17ºC [Devauchelle and Coves, 1988], whereas water-immersed F.…”

A review on broodstock nutrition of marine pelagic spawners: the curious case of the freshwater eels (Anguillaspp.)

To sustain eel aquaculture, development of reproduction in captivity is vital. The aim of this review is to assess our current knowledge on the nutrition of broodstock eels in order to improve the quality of broodstock under farming conditions, drawing information from wild adult eels and other marine pelagic spawners. Freshwater eels spawn marine pelagic eggs with an oil droplet (type II), and with a large perivitelline space. Compared with other marine fish eggs, eel eggs are at the extreme end of the spectrum in terms of egg composition, even within this type II group. Eel eggs contain a large amount of total lipids, and a shortage of neutral lipids has been implied a cause for reduced survival of larvae. Eel eggs have higher ARA but lower EPA and DHA levels than in other fish. Too high levels of ARA negatively affected reproduction in the Japanese eel, although high levels of 18:2n‐6 in the eggs of farmed eels were not detrimental. The total free amino acid amount and profile of eel eggs appears much different from other marine pelagic spawners. Nutritional intervention to influence egg composition seems feasible, but responsiveness of farmed eels to induced maturation might also require environmental manipulation. The challenge remains to succeed in raising European eel broodstock with formulated feeds and to enable the procurement of viable eggs and larvae, once adequate protocols for induced maturation have been developed.
