European eels (Anguilla anguilla) undertake spawning migrations of more than 5000 km from continental Europe and North Africa to frontal zones in the Sargasso Sea. Subsequently, the larval offspring are advected by large-scale eastward ocean currents towards continental waters. However, the Sargasso Sea is oligotrophic, with generally low plankton biomass, and the feeding biology of eel larvae ...

Since the mid-nineteenth century, a notable increase (0.60.8°C) in the Earth’s mean surface temperature has been documented and is continuing at an accelerated rate [1,2]. The European (Anguilla anguilla L.) an eel species of the moderate temperature zoneshas been dwindling since the eighties of the previous centuries [3] and is an endangered species [4]. Possible causes for its decline were in...

Intermuscular bones are found in the myosepta in teleosts. However, there is very little information on the development and ossification of these intermuscular bones. In this study, we performed an in-depth investigation of the ossification process during development in zebrafish (Danio rerio) and Japanese eel (Anguilla japonica). In Japanese eel, a typical anguilliform swimmer, the intermuscul...

The authorities in Anguilla sought technical assistance from CARTAC to conduct a comprehensive review if its customs legislation. It is recognized that the existing legal framework for outdated and does not have requisite foundation support modernization of Customs. Ministry Finance requested primary legislation be replaced by completely new act based on CARICOM model and, where appropriate con...

The nuclear DNA content in Dicentrarchus labrax, Sparus aurata, Liza ramada, and Anguilla anguilla, was measured by flow cytometric analysis. Male human leukocytes were used as internal reference cells. Nucleated fish erythrocytes were stained simultaneously to human leukocytes with a staining buffer containing propidium iodide (PI). Nuclear DNA contents of target species were estimated in rela...

The changes in bacteriolytic and proteolytic activities of skin cathepsins L and B were studied Ž . in thermal-stressed European eel Anguilla anguilla . When fish were kept in 108C water, all activities increased to reach maximum levels at Day 8 with varying increasing rates of 3.0 Ž . Ž . Ž . proteolysis , 4.2 lysis of FlaÕobacterium columnare , 5.7 lysis of Vibrio anguillarum and 7.8 Ž . lysi...

In this article, it is shown that available genetic tools for the omnipresent parasite Anguillicoloides crassus in European eels Anguilla anguilla are sensitive to different immigration rates into local A. anguilla stocks for two separated river systems. Relying on four highly polymorphic microsatellite markers, it was inferred that under natural recruitment, nematode samples meet Hardy-Weinber...

Anguilla japonica and Anguilla marmorata share overlapping spawning sites, similar drifting routes, and comparable larval durations. However, they exhibit allopatric geographical distributions in East Asia. To clarify this ecological discrepancy, glass eels from estuaries in Taiwan, the Philippines, Indonesia, and China were collected monthly, and the survival rate of A. marmorata under varying...
