چکیده
We cloned and sequenced the mitochondrial (mt) control region (CR) and flanking transfer RNA genes (T, P, and F) of the striped mullet, Mugil cephalus and designed species-specific primers to amplify the entire CR in specimens from the Pacific (Hawaii), the Gulf of Mexico, and the Atlantic. We verified the absence of heteroplasmy and nuclear mtDNA duplications of this region in the organisms sampled, finding an extraordinary level of sequence divergence (mean 38-75% Tamura & Nei distance) between fish from both Oceans, including Japan. The CR of the mullet was variable in length (845-930 bp) and contained structural elements in common with other CRs, including a central conserved segment flanked by hypervariable regions and smaller conserved sequence blocks. Termination associated sequences, however, were not found. The CR of the striped mullet was rich in AT (~67%) and poor in GC.

متن کاملStomach content analysis of Mugil cephalus and Mugil curema (Mugiliformes: Mugilidae) with emphasis on diatoms in the Tamiahua lagoon, México.
A year-long research on the Mugil cephalus and M. curema diet was conducted. The food content in the cardiac portion of 192 stomachs revealed a great similarity in both species leading to two conclusions: sediments are their basic food and high levels of benthic diatoms are dominant. A total of 130 taxa were found (Nitzschia, Navicula, Amphora, and Cocconeis dominated). Other food components we...

The study describes the infection of the acanthocephalan, Neoechinorhynchus agilis sp. The (grey mullet) Mugil cephalus is highly valued food along the Corentyne coast, Berbice, Guyana. The fish Mugil cephalus were collected from Bush Lot, Whim, 43 Village 63 Beach and 79 Village, Corentyne coast. The infections with the parasites were observed in posterior region of the intestine, liver and mu...
متن کاملPredicting NOEC and Safe Concentration for Mugil cephalus and Perna viridis to Mercury
No-effect concentration as well as safe concentration of mercury was evaluated by exposing Perna viridis and Mugil cephalus to 24-hour static renewal bioassay for 96-hours. The 96-hour LC50 value was 75 and 129 μg/l Hg for Mugil cephalus and Perna viridis. Juvenile mullets were more sensitive than green mussel. The safe concentration calculated were 0.75 and 1.29 μg/l Hg. The no-effect concentr...
