This work compared the use of dextrose and molasses as carbon sources for biofloc development, water quality maintenance, microorganism composition and growth performance of Litopenaeus vannamei juveniles in biofloc ...

This study aimed to evaluate the effects of adding guar gum, a non-starch polysaccharide, to the diet of Mugil liza juveniles. The juveniles (mean weight = 0.38 ± 0.01 g) were fed one of three diets with increasing ...

The Medium Littoral of the Rio Grande do Sul coastal plain comprises about 2.5 million inhabitants living in the 17 municipalities along the Patos Lagoon coast. The Patos Lagoon is the largest lagoon in Brazil and the ...

Fish are potentially submitted to water acidification when reared in recirculating aquaculture systems. This study evaluated the responses of juvenile cobia Rachycentron canadum after acute exposure to acid water. ...

Most fishes require a minimum threshold light intensity to be able to develop and grow. The aim of this study was to evaluate the effect of light intensity on growth of juvenile Brazilian flounder Paralichthys orbignyanus. ...

Prevention is the most viable disease management strategy in aquaculture, and prevention is primarily driven by strategies to avoid or minimize the effects of stress. Unfortunately, there is little information available ...

A variabilidade temporal em curta escala de clorofila a, abundância e composição de ftoplâncton e ciliados e de fatores abióticos foram analisados no estuário da Lagoa dos Patos durante dois períodos, o primeiro na primavera ...

This study evaluated the median lethal concentra-tion values (LC50) and the histopathological effectsof un-ionized ammonia (NH3--N) on juvenile mar-oon clownfishPremnas biaculeatus. After 96 h ofexposure to different ...

The flounder, Paralichthys orbignyanus, is found in coastal and estuarine waters of the Western South Atlantic Ocean. It is being considered for aquaculture due to its high market price and wide tolerance to environmental ...

The influence of hydrothermal venting activity on arsenic (As) and mercury (Hg) accumulation was investigated in the shallow-water marine ecosystem of Concepcion Bay in the western Gulf of California. Geochemical data ...

The geochemical mobility of arsenic and somemetals in the fine fraction of 20 alluvial sediment samplescollected along the thalweg of the San Antonio arroyo wasassessed in the abandoned gold mining district of the semi-arid ...

We assessed and evaluated the performance of five ocean reanalysis products in reproducing essential hydrographic properties and their associated temporal variability for the Weddell Sea, Antarctica. The products used ...

This study analyzes and discusses data taken from oceanic and atmospheric measurements performed simultaneously at the Brazil-Malvinas Confluence (BMC) region in the southwestern Atlantic Ocean. This area is one of the ...

O projeto MOVAR (Monitoramento da Variabilidade do Transporte de Calor entre o Rio de Janeiro-RJ e a Ilha da Trindade-ES) foi criado com intuito de estudar a circulação na região oceânica ao sul da Cadeia Submarina de ...

The Antarctic intermediate and deep water masses present in the Atlantic sector of the Southern Ocean were quantified through the inverse method known as Optimum Multiparameter (OMP) analysis. The method was applied to ...

The objective of this study was to determine the influence of marine shallow-water hydrothermal systems in Mapachitos, bahia Concepcion, on the composition of surficial sediments in the surrounding area of this bay. The ...

Copper and zinc are common elements in paint residues and can be toxic to estuarine organisms. This study aims to determine the labile dissolved and labile particulate fractions (LPFs) of copper and zinc in the estuarine ...

The dissolved labile and labile particulatefractions (LPF) of Cu and Zn were analyzed duringdifferent seasons and salinity conditions in estuarinewaters of marina, port, and shipyard areas in thesouthern region of the Patos ...
