The objective of the current study was determined chemical composition (including protein, lipid, ash and moisture) and content of minerals (Zn, Mn, Fe, Cu, Cr, Ca, Na, Mg, Mo, P, Se, K, I and F) in five fish species from the South Caspian Sea. The chemical analysis revealed that the protein content of common kilka, Caspian kutum, common carp, pike perch and golden grey mullet was 18.35%, 21.39...

This report describes a viral epidemiological study of wild fish around the Gulf of Cadiz (southwestern Iberian Peninsula) and is focused on infectious pancreatic necrosis virus (IPNV), viral hemorrhagic septicemia virus (VHSV), and viral nervous necrosis virus (VNNV). One fish species (Chelon labrosus) was sampled inside the gulf, at the mouth of the San Pedro River. Another 29 were sampled, i...

It differs from all other species of Indochinese and Thai-Malay Cyrtodactylus by having a maximum SVL of 70.1 mm (n=6); no distinct dark blotches on the head in adults; no continuous nuchal loop; a blotched dorsal pattern; 17-19 intero...

We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series ...

Highly productive and vulnerable habitats such as maerl crinoid beds are subject to severe impacts from trawling in Mediterranean Sea. One of the most valuable target species that inhabit these is red mullet, Mullus barbatus, which can achieve there optimum feeding conditions based on infauna, provide some Fatty Acids (FAs) Polyunsaturated (PUFAs) essential shaping life history traits growth re...

Spermatogenesis and sperm ultrastructure are examined and described for the first time in the garden slug Limax flavus (Gastropoda, Pulmonata, Stylommatophora) in Egypt. Spermatogonia show round nuclei with patchy heterochromatin. The primary spermatocytes are characterized by the presence of synaptonemal complexes. The secondary spermatocytes are reduced in size and contain less cytoplasm and ...

the objectives of this study were to determine the age, growth, mortality and exploitation of a commercially important fish of northeastern mediterranean sea, mullus barbatus from the karatas coast of iskenderun bay during september 2002 and april 2003. a total of 212 specimens of red mullet were collected by monthly sampling using traditional bottom trawl net by commercial vessel (coskun reis,...

A new species of the hitherto monotypic genus Chalarodon is described from southern Madagascar and a lectotype (ZMB 4360) is designated for C. madagascariensis Peters, 1854. The new species of terrestrial iguana, Chalarodon steinkampi sp. nov., is defined by several morphological characters and by concordant differentiation in mitochondrial and nuclear DNA with >5% uncorrected pairwise genet...
