“…Consequently, some case studies have shown evidence of negative effects on benthic communities via the intense biodeposition of feces and pseudofeces (e.g., Gilbert et al, 1997;Smith & Shackley, 2004;da Costa & Nalesso, 2006;Dubois et al, 2007;Fabi et al, 2009). For example, a large quantity of organic biodeposition can dramatically decline the abundance of benthic fauna and species richness (Smith & Shackley, 2004;da Costa & Nalesso, 2006;Dubois et al, 2007). In the most serious cases, the opportunistic deposit-feeders will dominate in the benthic infauna (Smaal, 1991;Fabi et al, 2009) or even the seabed will be devoid of macrobenthic organisms (Grall & Glémarec, 1997;Callier et al, 2008).…”

“…Mariculture of bivalves in suspended culture systems is attractive from economic and environmental standpoints, because good growth results can be achieved completely from naturally occurring organic food sources which can greatly reduce the culture cost and environmental pollution from the artificial food supplements (Yang & Zhou, 1998;da Costa & Nalesso, 2006;Gibbs, 2007;Fabi et al, 2009). Moreover, the benthos can also benefit from the suspended culture system.…”

“…The long-term sustainability of bivalve cultivation depends on the maintenance of the functional health of the natural ecosystem, and thus the evaluation of the effects of bivalve raft cultures on the underlying seabed environment is urgently recommended (Fabi et al, 2009). Macrobenthic communities have been used as bioindicators for monitoring coastal pollution and organic accumulation for a long time (Pearson & Rosenberg, 1978;Shin et al, 2004;Gaudêncio & Cabral, 2007) and have been proved to be a useful tool to monitor the sustainability of mariculture practices (da Costa & Nalesso, 2006). However, previous studies have drawn distinctly different conclusions, and the impacts of shellfish culture were within the range from no or minimal negative effects to significantly positive and negative changes (Cranford et al, 2009).…”

Effects of intensive scallop mariculture on macrobenthic assemblages in Sishili Bay, the northern Yellow Sea of China

To elucidate the effects of scallop mariculture on the macrobenthic community in a moderate energy system, bimonthly samples from four transects along a distance gradient in Sishili Bay, the northern Yellow Sea of China, were investigated. Differences in macrobenthic community structure along the distance gradient were evaluated using univariate and multivariate analyses. The AZTI's Marine Biotic Index (AMBI) and multivariate-AMBI analyses indicated that the macrobenthic community suffered little disturbance from the scallop culture. Consistently, the results of two-way analysis of similarities demonstrated that macrobenthic communities showed no difference along the distance gradient, but were significantly affected by the sampling months and transects. This conclusion was also confirmed by other univariate and multivariate analyses. The concentration of total organic carbon was 17.27 ± 6.05 mg g -1 , which is below the dangerous threshold of 35 mg g -1 toxic to benthic fauna. Combined results revealed that no detectable effects on the macrobenthic community were caused by intensive and long-term scallop culture in this moderate energy system. This is likely due to the influence of local hydrodynamics and it is recommended that intensive scallop farming be located in areas with strong tidal or current flows.

ABSTRACT. The relationships between environmental factors and temporal and spatial variations of benthic communities of three rocky shores of the state of Espírito Santo, Southeast Brazil, were studied. Sampling was conducted every three months, from August 2006 to May 2007, using intersection points. Chthamalus bisinuatus (Pilsbry, 1916) (Crustacea) and Brachidontes spp. (Mollusca) were the most abundant taxa, occupying the upper level of the intertidal zone of the rocky shore. The species richness was higher at the lower levels. The invasive species Isognomon bicolor (C. B. Adams, 1845) (Mollusca) occurred at low densities in the studied areas. The clustering analysis dendrogram indicated a separation of communities based on exposed and sheltered areas. According to the variance analyses, the communities were significantly different among the studied areas and seasons. The extent of wave exposure and shore slope influenced the species variability. The Setibão site showed the highest diversity and richness, most likely due to greater wave exposure. The communities showed greater variation in the lower levels where environmental conditions were less severe, relative to the other levels. Pilsbry, 1916 (Crustacea) e Brachidontes spp. (Mollusca) foram os táxons mais abundantes, ocupando os níveis superiores da zona entremarés dos costões. Nas zonas inferiores ocorreu um maior número de espécies. A espécie invasora Isognomon bicolor (C.B. Adams, 1845) (Mollusca) ocorreu em baixa cobertura nas áreas estudadas. O dendrograma indicou a separação das amostras das áreas expostas e abrigadas. Segundo os resultados das análises de variância, as comunidades foram significativamente diferentes entre as áreas e as estações do ano. O grau de exposição às ondas e a inclinação do costão influenciaram a variabilidade de espécies. Setibão apresentou os maiores índices de diversidade e de riqueza, provavelmente devido à maior exposição às ondas. As comunidades apresentaram maiores variações nos níveis inferiores, onde as condições ambientais são menos estressantes em relação aos outros níveis. KEYWORDS. PALAVRAS-CHAVE.Médio litoral, exposição às ondas, bentos, Espírito Santo.
