Egg quality in fish: what makes a good egg?
Reviews in Fish Biology and Fisheries, 1997Factors affecting egg quality are determined by the intrinsic properties of the egg itself and the environment in which the egg is fertilized and subsequently incubated. Egg quality in fish is very variable. Some of the factors affecting egg quality in fish are known, but many (probably most) are unknown.

AbstractA ‘fishy’ or ‘crabby’ taint in brown eggs from commercial flocks was associated with the use of capelin meal as a protein supplement and was reproduced under controlled conditions. Analysis of eggs and samples of the meal established that trimethylamine (TMA) was responsible for the taint and that the meal may contain rich sources of TMA in the

Unbound sialic acids in fish eggs
Biochimica et Biophysica Acta, 1960Abstract Relatively large quantities of sialic acids occur in an unbound form in trout eggs. Both N-glycolyl and N-acetylneuraminic acid are found within one cell, the trout egg. Preliminary studies on the permeability of the egg to free sialic acids are reported.

Publisher Summary Varying egg quality is one of the limiting factors for successful mass production of fish fry. It may also cause some of the variability in recruitment observed in many wild stocks, since poor egg quality may decrease the survival potential of the hatched larvae.

Egg quality and egg pigment content in salmonid fishes
Aquaculture, 1985Abstract The widespread belief in the superior quality of highly pigmented eggs is examined by bringing together evidence concerning the effect of the carotenoid content of salmonid eggs on their viability. It is concluded that, in rainbow trout, there is not a simple linear relation between these two quantities.

The spermatozoa and eggs of the cardinal fish
Journal of Fish Biology, 2003The gametes of the cardinal fish Apogon imberbis had the following characteristic: the semen contained both biflagellate ( c. 20% in the investigated samples) and monoflagellate ( c. 80%) spermatozoa. The spermatozoa were acrosomless, had an ovoid head, and a cylindrical midpiece. The midpiece contained a high number of mitochondria (seven–10).

On fish eggs and larvae in the Skagerrak
Sarsia, 1968Abstract The distribution of fish eggs and larvae shows the importance of the current system in the Skagerrak. The Jutland, Baltic, and Norwegian (coastal) currents form together an anti-clockwise circulation which results in the ichthyoplankton drifting in a characteristic way.
