“…The histochemical procedures, hereby applied have revealed that the above mentioned lipid yolk droplets were of lipoid nature, the cortical granules consisted of polysaccharides whereas yolk globules were constituted of both proteins and polysaccharides. Similar observations were obtained in Thunnus thynnus and Xiphias gladius (Sarasquete et al, 2002;Ortiz-Delgado et al, 2008). Many researchers agree that the cortical alveoli (yolk vesicles) consist of polysaccharides (Guraya, 1965 andMaksimova, 1991).…”

“…Histological analysis of the reproductive system of fishes provides more comprehensive knowledge on the gonad functions and highly precise characterization of the oogenesis phases and the reproductive cycle of species (Ortiz-Delgado et al, 2008;Mandal, et al, 2020;Senarat et al, 2021). Oogenesis is a complicated process, which includes the transition of oogonia into oocytes and their growth to fully developed eggs, ready for propagation (Grier et al, 2009;Viana et al, 2018).…”

“…The histological investigation of fish oocyte development during the reproductive cycle of fish species has been studied by several authors (Ortiz-Delgado et al, 2008;Charitonidou et al, 2022;Shilta et al, 2022;Porcu et al, 2022). In addition, the histochemical analysis of oogenesis has received attention regarding teleosts (Mayer et al, 1988;Sarasquete et al, 2002a, b;Corriero et al, 2004;Motta et al, 2005;Calabro et al, 2008;Reading et al, 2018).…”

Understanding the structure of the reproductive system of fishes for commercial production allows the development of productive strategies. In the present study, the histochemistry of the oogenesis of Mugil cephalus in the natural habitat was investigated. The oocyte development was followed up via both histological and histochemical techniques during the ovarian cycle of M. cephalus in Bardawil Lagoon. During ovarian development, only one set of oocytes was annually found. Five stages of oocyte development were identified in M. cephalus; namely, primary, vesicles, primary yolk, secondary yolk, and tertiary yolk oocytes. Yolk deposition occurred during four (vitellogenic) stages, including vesicles, primary yolk, secondary yolk and tertiary yolk oocytes. The histological and histochemical findings revealed that three types of yolk inclusions are formed during vitellogenesis. These included lipid yolk droplets, yolk globules and cortical granules. Lipid yolk droplets were deposited first, followed by yolk globules and cortical granules. The former inclusions had lipoid nature; the cortical granules consisted of polysaccharides, while yolk globules contained both proteins and polysaccharides. Such analysis should provide a basis for the study of the endocrine control of vitellogenesis in oocytes and give important information for hatchery management for inducing the spawning of M. cephalus in aquaculture systems.

“…However, using PAS, the initial positively stained yolk granules later appear unstained, indicating changes in carbohydrate contents of the yolk composition. In the swordfish, the yolk globules were found to be faintly positive for PAS, denoting some neutral glycoproteins and glycolipids contents, and no changes in positivity were mentioned (Ortiz-Delgado, Porcelloni, Fossi, & Sarasquete, 2008). In contrast, yolk globules in the red drum were not stained with PAS (Grier, 2012).…”

The goldfish (Carassius auratus) is a freshwater fish that belongs to one of the largest vertebrate families, the Cyprinidae, of the order Cypriniformes, being native from East Asia (Nelson, 2006). Selective breeding over the years led to the development of numerous breeds of goldfish, which vary in colour, body shape, size, fins and eye configuration, and are used for ornamental along with research purposes (Smartt, 2001). The goldfish is a cyprinid closely related to the most used fish in research laboratories worldwide: the zebrafish (Danio rerio). It has been used increasingly over the years as model organism due to its ample size range, easy handling, great adaptability, commercial availability, and low costs of rearing and husbandry, which make it an excellent tool for fundamental and applied re

“…In teleosts, high content of Sias is present around the oocytes, in the zona radiata (the equivalent of the mammals ZP) of the dusky grouper Epinephelus marginatus (Mandich et al, 2002), the swordfish Xiphias gladius (Ortiz-Delgado et al, 2008), the bluefin tuna Thunnus thynnus (Sarasquete et al, 2002), and the trout (Kitazume et al, 1994). Kdn is the major component of the vitelline envelope of the chum Oncorhynchus keta and kokanee salmon Oncorhynchus nerka while cherry salmon Oncorhynchus masou contains an analogous family of mucin-type glycoproteins with ending Neu5Gc as the major component (Inoue and Inoue 1997;Gallo and Costantini, 2012).…”

Sialic acids are a family of 9-carbon monosaccharides with particular physicochemical properties. They modulate the biological functions of the molecules that carry them and are involved in several steps of the reproductive process. Sialoglycoproteins participate in the balance between species recognition and specificity, and the mechanisms of these aspects remain an issue in gametes formation and binding in metazoan reproduction. Sialoglycoproteins form a specific coat at the gametes surface and specific polysialylated chains are present on marine species oocytes. Spermatozoa are submitted to critical sialic acid changes in the female reproductive tract facilitating their migration, their survival through the modulation of the female innate immune response, and the final oocyte-binding event. To decipher the role of sialic acids in gametes and at fertilization, the dynamical changes of enzymes involved in their synthesis and removal have to be further considered.
