“…Moreover, the particle size of sediment in Sishili bay showed over 70% similarity (over 85% in the central part of the bay) (Liu et al, 2012a). In the light of the reference, sample of 0.1 m 2 or smaller per station has been found sufficient to reliably distinguish different macrobenthic communities (Ferraro et al, 1994(Ferraro et al, , 2006Stenton-Dozey et al, 1999;Fabi et al, 2009;Tomassetti et al, 2009). Thus, three replicates and sample of 0.15 m 2 per station should be sufficient to avoid Type II errors, which could result from a lack of sampling power and replication, for the highly homogenous nature of the sediment.…”

“…As the most commonly used biotic index in the European Water Framework Directive (WFD) (Borja et al, 2009), AMBI and m-AMBI have been proven to be efficient in detecting the degradation of habitat quality by different human pressures in different bodies of water along the European coast Pinto et al, 2009;Tomassetti et al, 2009), the Indian coast (Bigot et al, 2008), the USA (Borja et al, 2008), South America, and Hong Kong , especially in regard to mariculture (Borja et al, 2009). According to the guidelines for the use of AMBI , when the percentage of taxa that are not assigned is [20%, the result should be evaluated with care because there may be errors in the interpretation, and if it is [50%, the AMBI should not be used.…”

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.

“…This variability among different fish farms was considerably higher than the variability observed for intermediate and control distances at the same scale and, additionally, happened independently of the time of sampling. The effects of aquaculture activities on bottom sediments, such as organic enrichment (derived from an excess of uneaten food and fish egesta), silting, increased oxygen demand, etc., vary from farm to farm and depend on local variables such as hydrographic regime, sediment type and water depth, as well as management variables such as fish production, efficiency of feeding method and feed quality (Tomassetti et al 2009). Therefore, these differences among fish farms are probably related to a combination of local and management variables.…”

A 5-factor design survey was carried out to examine the spatial distribution at different scales of amphipod assemblages and sedimentary variables in soft bottoms adjacent to coastal aquaculture installations. Natural variability of sediment variables showed the highest values at the scales of sites (10s of meters) and locality (1 to 10 km), while the greatest component of variation of amphipod assemblages occurred among replicates (on the scale of meters). Regarding the influence of coastal aquaculture, the highest variability of the environmental variables was observed among the different fish farms. On sandy localities, the influence gradient of coastal aquaculture was determined by total free sulphides, whilst, in muddy localities, the main variable was δ 15 N. This study has important consequences for the establishment of a clear and effective methodology for studying and monitoring the impact of fish farming, highlighting the complicated establishment of a widespread pattern of effects by coastal aquaculture. The necessity to apply a high replication effort at several spatial scales, especially at the scales of meters and 10s of meters, to increase the precision of estimates of assemblage composition should be taken into consideration.

“…The impacts of feeding and moving activities of cultured organisms on ecosystem are directly from aquaculture itself (DelValls et al, 1998). The culture effects also associated with the effects of pets, creation of novel habitat, and alteration of the nutrient cycling (Drak and Arias, 1997;Han et al, 2001;Forrest et al, 2009;Tomassetti et al, 2009). …”

a b s t r a c t a r t i c l e i n f oYellow River delta (YRD) is a typical example of a valuable coastal ecosystem that is under increasing anthropogenic threat in China. To understand the current health status of this region, three surveys in 2011 for the abiotic conditions and macrobenthic assemblages were performed. The concentration of trace metals were relatively low in the sediment at all sampling stations representing a good sediment quality. A total of 159 macrobenthic species were identified during the three surveys. ABC curves showed that the macrobenthic fauna at 8 sampling stations suffered disturbances from human activities. M-AMBI index indicates that the benthic ecological quality of YRD is currently still not in a good condition. Five trace metals, water temperature and depth were the main environmental variables affecting the distribution pattern of macrobenthic assemblages. Community succession has occurred over the past 60 years, as evidenced by changes of species composition, key species, distribution pattern and range.
