Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom. Methanol extracts of muscle, liver, peritoneal and stomach contents were analysed by HPLC and tandem mass spectrometry; histological examination was conducted on livers from captured mullet. Liver...

An image-processing algorithm, applied to images of common carp (Cyprinus carpio), St. Peter’s fish (Oreochromis sp.) and grey mullet (Mugil cephalus), successfully discriminated among the species. Fish images were acquired while they were swimming in an aquarium with their side to the camera. The algorithm was based on the method of moment-invariants (MI) coupled with geometrical consideration...

pesticides are used extensively in agricultural lands in northern provinces of iran which makes river ecosystems more vulnerable to pesticides pollution. this study was conducted in three river estuaries (babolrud, tajanrud and gorganrud), focusing mainly on the concentration levels of organophosphate pesticides (diazinon, malathion, azinphos-methyl) in the muscle tissue of golden mullet fish, ...

The striped mullet (Mugil cephalus L.) is distributed circumglobally in tropical and semitropical waters between latitudes 42°N and 42°S (Thomson, 1963; Rossi et al., 1998). Even though considered a marine species, striped mullet are euryhaline and can be found year round throughout the full range of estuarine salinities in the southeastern United States (Jacot, 1920; Anderson, 1958). Striped m...

Heterophyid metacercarial infections in brackish water fishes, i.e., perch, shad, mullet, redlip mullet, and goby, of Jinju-man (Bay), Kyongsangnam-do, Korea, were investigated using a digestion technique. Among 45 perch (Lateolabrax japonicus), the metacercariae of Heterophyopsis continua were found in 55.6% (18.5 metacercariae per fish), Stictodora spp. in 28.9% (3.6), and Metagonimus takahas...

We evaluated the survival of Streptococcus agalactiae from naturally infected wild mullet (Liza klunzingeri) and experimentally infected Nile tilapia (Oreochromis niloticus) frozen at 20 and 70 jC, respectively, for an extended period of time. The brain, eye, head kidney, and intestine of individually frozen wild mullet (N = 22), culture positive for S. agalactiae from fresh tissues following a...

Intestinal yeasts were isolated from 39 fish belonging to five different species of the Mugil genus. Among 42 isolates, 38 different strains belonging to 15 genera and 25 species were identified and characterized for adhesion to epitelial fish mucus, antagonistic properties against bacterial pathogens, production of enzymatic activity and biochemical properties.A great variability was found in ...

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...

Grey-mullet are heterosexual fish and gonochorism is the general rule. Cytological cnalysis of sex-differentiation was studied by light microscopy (Stenger, 1959 ; Leray, 1968 ; Thong, 1969 ; Cassifour, 1975), but germ-cell characteristics were not sufficiently defined at this level and no distinction could be made between primordial germ-cells, oogonia and spermatogonia. Electron microscopy ha...
