The present study estimated the human daily and weekly intake of inorganic elements due to consumption of fish in Rio de Janeiro state and the associated potential health risks posed by some toxic elements. All samples analyzed had values of Cd and Pb below the Maximum Tolerable Limits of 3.0 mg kg-1 for Pb and 1.0 mg kg-1 for Cd; only Mugil cephalus, Cynoscion leiarchus and Caranx crysos had A...

Abstract: Aim We investigate the length-weight relationship estimates of seventeen species caught using an artisanal purse seine in Abrolhos Bank, a tropical estuarine complex eastern Brazil. Methods From February 2012 to November 2013, fish were collected monthly small with total 84 landings. The captured mangrove margins during high tide and retrieved after six hours at depths ranging from 1....

Climate change affects the shift range distribution of species, especially among mobile and this phenomenon can alter ecosystems impacts human activities. Fishing is an anthropic activity that undergoes effect not only introduction increase non-native species but also native thermophilic ones. Some these become a commercially exploitable resource. However, information often obscured by negative...

Marine predators will often perform diel and seasonal movements associated with specific habitats. In tropical areas, mesophotic coral reefs may be an important habitat type for many predators, but their use of these areas has rarely been investigated. We used results of acoustic telemetry and stable isotope analyses to investigate the diel and seasonal movements of Galapagos sharks Carcharhinu...

In the waters surrounding Banco Chinchorro in the Mexican Caribbean are spawning and nursery areas for many types of fish. In this natural environment, as opposed to under controlled laboratory conditions, it is almost impossible to link an individual egg to the adult that laid it. This makes identifying the species of the eggs difficult. However, DNA barcodes have made this easier. In the pres...
