The aim of this study was to evaluate the use of gonadal alterations in the thinlip grey mullet (Liza ramada) as a biological indicator in assessing aquatic ecosystems health, with particular emphasis to river ecosystems exposed to sewage discharges. For this purpose, the reproductive status and the presence of gonadal alterations were studied in 206 mullets collected from two sites on the low ...

Some reproduction characteristics of keeled mullet, Liza klunzingeri, were studied during Apr. 2003 to Feb. 2004 in Khuzestan waters of the Persian Gulf. A total of 836 samples were monthly collected from two fish landings of Bahrekan and Hendijan; 727 specimens were studied from point of sex determination, and 60 specimens were studied from the fecundity point of view. This species was found t...

Histological changes and maturity stages during the reproductive cycle of the ovaries of Klunzinger's Mullet (Liza klunzingeri) were investigated. The evaluation of the spawning season was carried out based on monthly samples from 3 stations in the Persian Gulf and the Oman Sea. Sex ratio was approximately 1:3 (M: F). The maturity stages of female L. Kluningeri are: Virgin, Developing Virgin, D...

Beta-defensins are important part of innate immunity of fish, which are the first defense line against invading pathogens. In this study, the β-defensin (Lhβ-defensin) gene was cloned from spleen tissue of soiny mullet (Liza haematocheila). Lhβ-defensin cDNA was 747 bp in length, encoding 63 amino acids. Sequence alignment revealed that Lhβ-defensin contained six conserved cysteine residues and...

In this study growth and reproductive biology of endemic new species Acanthobrama thisbeae in Sır Reservoir were investigated. The population composed 80.6% female 19.40 % male individuals. individuals' total lengths (mm) weights (g) varied between 130.4 to 260.5 mm 12.92 203.89 g, respectively. Age groups 2 8 identified the majority sample was 130 180 (80.22%). length-weight relationship for a...

Due to the increasing concern of consumers about farmed fish contamination, in this study, different wild and species (Nile tilapia (Oreochromis niloticus), gray mullet (Mugil cephalus), thin lip (Liza ramada) commonly consumed Egypt, were chemically analyzed for presence heavy metals, antibiotics, polycyclic aromatic hydrocarbons, organochlorine pesticides residues, hormones microbiologically ...
