“…This result is comparable to the growth performance of the previous studies in which vitamin C and Cu were quantified for its adequate dietary requirement for P. monodon [14,15]. Shrimp fed diets with high Cu level had significantly depressed growth regardless of vitamin C supplementation level.…”

“…Also, Cu is a ubiquitous metal present in aquafeeds, as impurities in fertilizers and as active principles of pesticides used in the activity (Boyd and Massaut, 1999;Tacon and Forster, 2003). Copper is toxic to phytoplankton and the shrimps proper (Bainy, 2000;Chen and Lin, 2001;Lee and Shiau, 2002).…”

Fate of copper in intensive shrimp farms: bioaccumulation and deposition in pond sediments

We present the distribution of Cu in water, sediments and biomass from intensive shrimp (Litopenaeus vannamei Boone, 1931)) farming in northeastern Brazil. The results show no difference in dissolved Cu concentrations between waters entering and leaving the ponds. However, there was a large export of particulate Cu to adjacent environments, showed by extremely high particulate (112 µg.L , being 5 to 7 times higher than the local background. Pond management procedures result in a peculiar vertical distribution of Cu with peak values occurring at sub-surface depths in pond bottom sediments. Bioavailable Cu reaches about 20% of the total Cu content in sediments. Notwithstanding the relatively high Cu bioavailability, concentrations in shrimp muscle (23.2 to 63.4 µg.g -1 d.w.) were similar to reported values for reared and natural L. vannamei populations, and much lower than acceptable maximum limits for human consumption. Concentrations in the exoskeleton were always higher than in muscle. Increasing Cu mass, and to a lesser extent Cu concentrations in muscle tissues, occurred simultaneously to a decrease in Cu mass and concentrations in the exoskeleton and vice versa, suggesting a dynamical exchange of Cu between the two compartments. Although Cu fate in intensive shrimp culture does not result in increasing Cu exposure to consumers, the activity is an important source of this metal to adjacent ecosystems, in particular in the pristine environments where most aquaculture activities in NE Brazil takes place. , sendo estes valores de 5 a 7 vezes mais altos que as concentrações naturais dos solos e sedimentos locais. O manejo dos tanques de criação resulta em perfis de distribuição de Cu em sedimentos com maiores concentrações em subsuperfície. A biodisponibilidade do Cu nestes sedimentos é elevada e atinge cerca de 20% da concentração total. Apesar da biodisponibilidade elevada, as concentrações de Cu em músculo do L. vannamei (23.2 a 63.4 µg.g -1 peso seco) são similares aos valores reportados para populações naturais da espécie e em diversos de cultivo em outros países, e estão bem abaixo dos limites máximos permitidos para consumo humano. As concentrações de Cu no exoesqueleto foram maiores que no músculo. Um aumento da massa de Cu em músculo ocorreu simultaneamente à diminuição do Cu no exoesqueleto e vice-versa sugerindo uma troca dinâmica do Cu entre os dois compartimentos. Embora a presença do Cu no cultivo intensivo do L. vannamei não represente exposição significativa para os consumidores, a atividade é fonte importante de Cu para os sistemas aquáticos adjacentes.

Therefore, dilution capacity of the estuary has been decreasing over the past decades, maximizing the potential effect of pollutant emissions from anthropogenic sources.

BACKGROUND: Macro and trace elements have significant impacts on human health. Yet, information of elemental content in seafood is still scarce. Green crab Carcinus maenas and velvet crab Necora puber are mainly caught off English, Scottish and French coastal waters and live transported to Southern Europe, where they are consumed. During transportation, mortalities can reach 50% and dead animals are regularly commercialized for human consumption. The present study characterises the elemental composition of both species.
