Molecular polymorphisms (allozyme and amplified fragment length polymorphisms (AFLP)) were investigated in the mullet specie’s Liza ramada and Liza saliens to determine levels of genetic variability and assess possible correlations between the population genetic structure and the specie’s adaptability to shallow water environments. The thinlipped (L. ramada) and the sharpnose (L. saliens) mulle...

The Esmoriz-Paramos is a lagoon of great ecological significance located on the Northwest coast of Portugal. The quality of water and sediment within this ecosystem has been gradually degraded due to the discharges of mostly untreated industrial waste and domestic sewage. Contaminants include heavy metals that can be taken up by fish from water, food, sediments, and suspended particulate materi...

We applied a combined molecular and morphological approach to resolve the taxonomic status of Saccocoelium spp. parasitizing sympatric mullets (Mugilidae) in the Mediterranean. Eight morphotypes of Saccocoelium were distinguished by means of multivariate statistical analyses: 2 of Saccocoelium obesum ex Liza spp.; 4 of S. tensum ex Liza spp.; and 2 (S. cephali and Saccocoelium sp.) ex Mugil cep...

In Tunisia, mugilid and soleid fish species are among the most important resources of the Tunisian lagoons. These fish are of great economic value and they are highly valued for their flesh. Some species of mullet from Tunisian waters, especially Mugil cephalus and Liza ramada, have been found to be infected with several myxosporean species, all of which belonging to the genus Myxobolus Bütschl...

this study is attempted to compare the number of rings and circular scales that are formed during various ages on liza saliens. sampling was carried out monthly during 2012-2013 using beach sine fishing nets. 102 specimens of different sizes were collected and transferred to the laboratory in boxes containing ice. the age of fish was determined by the number of annual rings as well as, the numb...
