Fish egg quality can be defined as the ability of the egg to be fertilized and subsequently develop into a normal embryo. Similarly, sperm quality can be defined as its ability to successfully fertilize an egg and subsequently allow the development of a normal embryo.

All fish eggs are surrounded by an envelope, called the zona pellucida (ZP), that plays various roles during oogenesis, egg deposition, fertilization, and embryogenesis. The fish egg ZP consists of only a few proteins that are homologs of mammalian ZP proteins ZP1, ZP3, and ZP4. Unlike the situation in mammals, in fishes there are often multiple copies

Microinjection of Marine Fish Eggs
2018Microinjection is a powerful tool for studying embryonic development and analyzing gene functions in fish. This technique was first applied to model species of fish such as zebrafish and medaka whose egg chorions could be removed or softened before microinjection.

Aeromonas species in fish, fish-eggs, shrimp and freshwater
International Journal of Food Microbiology, 1997Aeromonas spp. are common contaminants of fish and seafood. They also are ubiquitous in the water environment. Aeromonas spp. were identified in 27 (93%) of 29 fish, in 17 (100%) fish-egg, in two (16%) of 12 shrimp samples and in 23 (100%) freshwater samples. In total, 117 Aeromonas strains were isolated from 69 positive samples, several samples having

Nonuniform distribution of enzymes in fish eggs
Journal of Experimental Zoology, 1982AbstractThe distribution of enzymes in the blastoderm and the yolk was investigated in the eggs of the bony fish, Misgurnus fossilis. The total activities of lactate dehydrogenase (LDH), glucose‐6‐phosphate dehydrogenase (G‐6‐PD), and aldolase (ALD) did not change during early development.

Amino acid component in the fish egg
Developmental Biology, 1972Abstract The free amino acids and the amino acids of peptides and proteins in Oryzias eggs have been quantitatively determined by the amino acid analyzer. Among the free amino acids, glutamic acid, serine, and alanine occur in large amounts and glycine is present in a small quantity. Among the protein amino acids, aspartic and glutamic acids, proline,

Physiology of Fertilization in Fish Eggs
1962Publisher Summary Knowledge of the physiology of fertilization of fish eggs seems to be most important not only for an understanding of the basic phenomena of fertilization in vertebrates but also for its bearing on fish culture. Sperm–egg interacting substances have been demonstrated in some fishes.

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
