Reproductive biology of the mullet Mugil liza (Teleostei: Mugilidae) in a tropical Brazilian bay
The reproductive biology of Mugil liza Valenciennes, 1836 is described as a contribution to an elaborate management programm. A total of 243 specimens (89 males and 154 females) were collected in the Sepetiba Bay in south-eastern Brazil from July/2006 to June/2007. The gonadosomatic index (IG) and the sequential development of the ovaries observed through histological studies suggested that the...
متن کاملThe Mugil curema species complex (Pisces, Mugilidae): a new karyotype for the Pacific white mullet mitochondrial lineage
Recent molecular phylogenetic analyses have shown that the Mugil curema Valenciennes, 1836 species complex includes M. incilis Hancock, 1830, M. thoburni (Jordan & Starks, 1896) and at least four "M. curema" mitochondrial lineages, considered as cryptic species. The cytogenetic data on some representatives of the species complex have shown a high cytogenetic diversity. This research reports the...
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...
متن کاملAssessment and management of white mullet Mugil curema (Valencienne, 1836) (Mugilidae) fisheries of the south coast of São Paulo state, Brazil.
There is intense fishing activity, mainly artisanal, in the Cananéia, Iguape and Ilha Comprida Estuarine System. White mullet (Mugil curema) is one of the local fishery resources and is usually caught with gillnets and fish traps. This study aimed to characterise the Mugil curema fisheries thereby underpinning the management of the species in the region. The study was developed with data collec...
متن کاملLigophorus pilengas n. sp. (Monogenea: Ancyrocephalidae) from the introduced So-iuy mullet, Mugil soiuy (Teleostei: Mugilidae), in the Sea of Azov and the Black Sea.
The monogenean Ligophorus chabaudi was originally described on the gills of the flathead mullet, Mugil cephalus, and was subsequently reported on the So-iuy mullet, Mugil soiuy. However, the morphology of sclerotized parts and multivariate statistical analyses suggest that the form from the So-iuy mullet represents a new species. This study provides a description of the new species Ligophorus p...
