“…The present ultrastructural study showed that the vitelline glands in L. grandid were surrounded by interstitial cells between the developing vitelline cells. This agreed with Metadena depressa (Samuel et al, 2012) and Aphallus tubarium (Greani et al, 2016) But, this disagreed with (Taelab and Lashein, 2013;Arafa and Salama, 2019), they didn't report interstitial cells between vitellocytes. However, al.…”

“…Vitelline cells provide the material necessary for the formation of the eggshell and the essential nutriant material for development of future embryo (Grant et al, 1977;Irwin and Maguire, 1979). Trematoda oogenesis was studies by the light and electron microscope (Yosufzai 1953;Saxena 1979;Gupta et al, 1984;Samuel et al, 2016;Arafa and Salama, 2019;El-Sayed et al, 2019;. These studies showed the general pattern of oocyte development in parasitic platyhelm-inthes showed that the main pattern of oogenesis is basically similar in digeneans (Gresson, 1964;Holy and Wittrock, 1986;Orido, 1987;1988;Poddubnaya et al, 2003).…”

“…The ultrastructural features of vitellogenesis in L. grandid resembled those found in different species of digenean trematodes, such as Maritrema feliui et al, 2011), Metadena depressa (Samuel et al, 2012), Orientocreadium batrachoides (Taelab and Lashein, 2013), Cainocreadium labracis ( et al, 2019), and Proctoeces sp. (Arafa and Salama, 2019).…”

“…This finding was also recorded in the advanced and mature vitelline cells of M. feliui ( widerski et al, 2011), C. labracis ( derski et al, 2019) and Proctoeces sp. (Arafa and Salama, 2019). The shape, number, size and the clusters of shell pellets during vitellogenesis greatly varied among digeneans especially whose vitelline cells produce large amounts of nutritive reserves as Crepidostomum metoecus (Greani et al, 2016).…”

The study gave TEM ultrastructural of vitellogenesis in Lecithochirium grandid, digenean intestinal parasite of Saurida undosquamis, four developmental phases (1, 2, 3 & 4) during vitellogenesis. Vitelline bundles were enveloped with fine fibrous layer surrounded with separ-ated circular muscle bands. Ultrastructural study showed that vitellocyte maturation comprised of increased extension of parallel cisternae of GER, increase in cell size and in the different phases increased numbers of pellets aggregation in clusters during vitellogenesis. In mature vitellocytes, there were large numbers of various aggregations such as aggregation of pellets in clusters; the important portion in construction of egg shell and a number of unsaturated lipid droplets. This agreed with different phases of oocyte development in parasitic Platyhelminthes.

The present work was carried out to study the length-weight relationships and condition factor of the commercial Bartail Flathead (Platycephalus indicus), in Bardawil lagoon, North Sinai, Egypt. Monthly, random samples of Bartail Flathead (Platycephalus indicus) were collected from the mixed catch of the main landing site at the Bardawil lagoon. 947 specimens of Platycephalus indicus varied from 17.9 to 52.1 cm with weights ranging between 27.6 and 1003.7 g. were collected from August to December during two fishing seasons 2019-2020. The length-weight relationship of Platycephalus indicus representing were Male: W= 0.0019 L 3.3502 (R 2 = 0.9677); Female: W = 0.0018 L 3.3635 (R 2 = 0.9822) and Combined sexes: W = 0.002 L 3.3402 (R 2 = 0.9815). The relationship equation showed a positive allometric (b > 3); the value of (b) equals 3.3502, 3.3635 cm and 3.3402 cm for males, females and combined sexes respectively. The condition factor for Platycephalus indicus during the study period was about 0.65 in males, 0.76 in females and 0.76 in combined sexes.
