Influência de um cultivo de camarão sobre o metabolismo bêntico e a qualidade da água

Abstract: Atividades de cultivo de camarão tendem a aumentar a taxa de sedimentação de matéria orgânica nos corpos hídricos receptores de seus efluentes, devido à excessiva produção de produtos de excreção e sobras de ração. Dependendo das condições ambientais, o sistema pode não apresentar condições de autodepuração, gerando um grande acúmulo de nutrientes ao longo da camada sedimentar e intensificação do metabolismo bêntico levando, muitas vezes, o ambiente a um processo de eutrofização e possível situação de anoxia. … Show more

“…To study nutrient and oxygen fluxes at the sediment-water interface, measurements were taken in situ using benthic chambers, similar to those used by Freitas et al (2008). Light and dark chambers were used for each incubation, with three replicate samples being taken for each chamber type to minimise the effects of spatial heterogeneity.…”

“…Benthic chambers, similar to those used by Freitas et al (2008) and Morata et al (2012;, were employed for the in situ calculation of the fluxes of DO, NH 4 + , NO 2 -+NO 3 -, PO 4 3-and Si(OH) 4 at the sediment-water interface.…”
