Abstract Many environmental monitoring works have been carried out using biomarkers as a tool to identify the effects of oil contamination on marine organisms; however, only few studies used sea urchin gonadal tissue for this purpose. Within context, present work aimed understand impact an spill, proposing use biomarker by trace metals in species Paracentrotus lividus. Biometric analysis, quantification analyses elements Cd, Pb, Ni, Fe, Mn, Zn, and Cu, well histopathological evaluations were...
Marine environmental pollution is a longstanding global problem and has particular impact on the Bay of Bengal. Effluent from different sources directly enters rivers region eventually flows into This effluent may contain radioactive materials trace metals pose serious threat to coastal environment, in addition aquatic ecosystems. Using gamma spectrometry atomic absorption spectrometry, comprehensive study was carried out radioactivity (226Ra, 232Th, 40K, 137Cs) metal (Cd, Pb, Zn, Cu, Ni,...
Cadmium (Cd) is considered a priority hazardous substance under the European Community Directive 2013/39 due to its ecotoxicity. The ragworm Hediste diversicolor (O.F. Müller, 1776), common species in estuaries and coastal lagoons, plays an important ecological role these ecosystems suitable bioindicator of environmental chemical contamination. In this study, H. was chosen as ecotoxicological model with aim evaluating responses Cd contamination, considering multi-biomarker approach...
Garra rufa has a high commercial value, but their rearing methods are still unknown. Aspects like an adequate daily dose and feeding frequency need to be investigated. This work aimed establish the optimal feed per day obtain satiation of rear specific size class G. rufa. A total 60 fish were distributed by six aquaria containing 10 fish. First, fed twice day, providing correspondent 1% body weight increasing 0.1 g/fish on following days, until finding leftovers next morning. Afterwards,...
A population of sea urchins, Paracentrotus lividus, from the central west coast Portugal was studied to characterise their reproductive biology and possible relationships with environmental factors. An annual gametogenic cycle found, a broad spawning season, May November, according relatively synchronous gamete maturation process. Depending on factors (temperature, photoperiod), two separate periods could be distinguished, more individuals maturing at same time. When this happened, first...
