Baseline levels of cadmium and lead were determined in muscle tissue and liver of hake (Merluccius merluccius) and red mullet (Mullus barbatus), two commercially important fish species from the eastern Adriatic. Concentrations of trace metals in liver (Cd: 6-183 microg kg(-1) w. wt. ; Pb: 39-970 microg kg(-1) w. wt.) were within the range of recently published data for the Mediterranean. In the...

Germ cell transplantation, a powerful assisted reproductive technology, is widely used to study the functional characterization of stem cells. The technology is also used for conservation and propagation of elite germlines. In teleost fish model, the technique has been successfully established to generate donor-derived gametes by transplanting primordial germ cells (PGC) or spermatogonial cells...

North American salmon once ranged from ocean waters near the Arctic Circle southward to southern New England on Atlantic and Mexico Pacific. The colonial industrial transformation of rivers oceans have led extirpation or endangered status many populations. Today, chronic anthropogenic stressors interact with climate change, which means that effective conservation must address changes in transfo...

Great civilizations flourished on banks rivers. The Kolong river, which was once a vibrant has transformed into most polluted due anthropogenic activities. present work needs much attention, as even Central Pol...

BACKGROUND Betanodaviruses are the causative agents of Viral Encephalopathy and Retinopathy (VER). To date, more than 50 species have proved to be susceptible and among them, those found in genus Epinephelus are highly represented. Clinical disease outbreaks are generally characterized by typical nervous signs and significant mortalities mainly associated with aquaculture activities, although s...

The hydrological connectivity between the salt marsh and the sea was partially restored in a Mediterranean wetland containing isolated ponds resulting from former salt extraction and aquaculture activities. A preliminary assessment provided evidence that ponds farther from the sea hosted very large numbers of the endangered Spanish toothcarp, Aphanius iberus, suggesting that individuals had bee...

—Action agencies have encouraged the development of a modified electrical fish barrier system to deter upstream movements of California sea lions Zalophus californianus as a means to reduce their predation on returning adult Pacific salmon Oncorhynchus spp. within rivers along the West Coast of North America. Given that the barrier system does not discriminate which species will experience elec...
