Farming of the freshwater fish is emerging in Brazil and many species from the wild are promising. The teleost matrinxã (Brycon cephalus) holds several characteristics such as fast growth rate, high commercial value and adaptability to artificial raring conditions, which make it a promising species for commerce. The use of pesticides in aquatic environment is frequent in Brazil, and methyl para...

Social behaviour of fossil hominoid species is notoriously difficult to predict owing to difficulties in estimating body size dimorphism from fragmentary remains and, in hominins, low canine size dimorphism. Recent studies have shown that the second-to-fourth digit ratio (2D : 4D), a putative biomarker for prenatal androgen effects (PAEs), covaries with intra-sexual competition and social syste...

Two species of Myxobolus are reported from the gills of Mugil cephalus collected at Goa, India: M. goensis n. sp. and M. parvus Shulman, 1962. Myxobolus goensis n. sp. forms digitiform or rounded plasmodia between the gill rakers. Their spores are oval in frontal view, with tapered anterior extremity, and lemon-shaped in lateral view, measuring 9.7 (9.5-10.5) microm in length, 6.6 (6-7.5) micro...

In this study, the fish species inhabiting Bolaman Stream drains to Black Sea from Fatsa coast (Ordu Province, Turkey) was reported for first time. The study caught out non-periodically by sampling seven stations in between July 2017 and November 2018. Fish samples were captured with an electroshock device. With it determined that fauna of is represented 10 five families (Acheilognothidae, Cypr...

The healthy live fish Mugil cephalus were purchased from lower Anaikkat in Kollidam River, Thanjavur District. Tamilnadu, India. Mucus was carefully scraped from the dorsal body using a sterile spatula, the collected fish mucus was stored separately at 4 °C for further use. Anticancer activity was done by laryngeal cancer cell lines. Primarily the hemolytic activity was done in chicken and goat...

Cavisoma magnum (Southwell, 1927) Van Cleave, 1931 was originally described from a sea bass, Serranus sp. and spotted surgeonfish, Ctenochaetus strigosus (Perciformes) off Sri Lanka before its more recent redescription from milkfish in the Philippines in 1995. These reports were based on only light infections of their host fishes. Of the few flathead grey mullets, Mugil cephalus (Mugilidae), th...

Besides traditional methods based on morphological characters, electrophoretic such as SDS-PAGE are preferred by taxonomists to make the right decision in species identification process. In addition, effect of environmental factors, pH, salinity, heat, and temperature protein profiles essential various studies. this study, we aimed determine degree relationship some fish species, Squalius lepid...

Hybridization between native and nonnative fish species is a major conservation issue, especially in ecosystems with high levels of endemism, such as Iberian streams. To date, hybridization the invasive bleak Alburnus alburnus has been reported for chub Squalius alburnoides S. pyrenaicus scattered locations only. However, spreading region, potentially increasing risks other species. gather more...
