“…In marine cage aquaculture, the fallowing of fish culture sites is mainly related to the cessation of input of waste though seasonal variations in sediment and environment parameters (Pereira et al 2004). Periodic abandonment is one of the best management tools for sustainable fish farming (Carroll et al 2003).…”

“…Several studies have reported that nitrogen and phosphorus released from fish cage can affect chemical parameters of sediment (Beveridge 1996;Zhang et al 2004;Yan 2005;Porrello et al 2005;Kullman et al 2007). Thus, monitoring of nutrients concentration in water and sediment during culture and fallowing periods could be useful for management of sustainable fish culture, such as obtaining the optimal time for fallowing, i.e., the duration required for the sediment to recover (Bron et al 1993;McGhie et al 2000;Macleod et al 2004Macleod et al , 2006Pereira et al 2004).…”

Nitrogen and phosphorus dynamics in relation to fallowing in a fish cage farm was investigated in a shallow lake in China. Four sampling sites were set: beneath the cages, at the cage sides, and 50 and 100 m east of the cage farm. Total nitrogen (TN) and total phosphorus (TP) in lake water and sediment were analyzed during a 2-year rearing cycle. The cage culture had a fish yield of 16.3-39.2 tonnes in the study period. Based on the mass balance equation, 1533-3084 kg TN and 339-697 kg TP were contributed to the lake environment. Nitrogen and phosphorous concentrations showed greater increase in the first culture period than in the second rearing cycle. No obvious changes were found at the sampling sites 50 and 100 m east of the cages during the study periods. Main impacts were found close to the cages (beneath the cages and at the cage side); the sampling points at the cage side showed relatively high TN and TP sedimentation. After 3 months of fallowing, water TN and TP decreased significantly but the sediment TN and TP contents remained high. Therefore, recovery seems to happen during fallowing but attention should be paid to whether the culture continues to operate in the future.

“…This fact may be due to the differences in the physico-chemical parameters of the Mediterranean, such as higher temperatures and the different type of sediment (carbonate sediments), compared with areas culturing salmon where most studies have been performed (e.g. Brown et al 1987, Morrisey et al 2000, Brooks and Mahnken 2003, Pereira et al 2004, Edgar et al 2005.…”

The aim of this work was to study the dispersion of particulate wastes derived from marine fish farming and correlate the data with the impact on the seabed. Carbon and nutrients were correlated with the physico-chemical parameters of the sediment and the benthic community structure. The sedimentation rates in the benthic system were 1.09, 0.09 and 0.13 g m Therefore, the level of fish farm impact on the benthic community might be underestimated if it is assessed by merely taking into account data obtained from waste dispersion rates. The benthic habitat beneath the fish farm, Maërl bed, was seen to be very sensitive to aquaculture impact compared with other unvegetated benthic habitats, with an estimated POC-carrying capacity to maintain current diversity of 0.087 g C m -2 day -1 (only 36% greater than the basal POC input). Environmental protection agencies should define different aquaculture waste load thresholds for different benthic communities affected by finfish farming, according to their particular degree of sensitivity, in order to maintain natural ecosystem functions.

“…Most of them are considered as opportunistic species, which have small-body size, and grow rapidly in response to a disturbance, especially organic enrichment [1], [5]. [16] found that, there was evidence of macrobenthic recovery fifteen months after fallowing. However, opportunistic species were still dominating, suggesting that the areas were moderately to slightly disturbed at the end of the study.…”

Abstract-Abundance-Biomass comparison (ABC) was applied to assess the level of environmental disturbance by the changes in the pattern of abundance and biomass of macrobenthic assemblages taken from various types of sediments. In the most sedimentary habitats, polychaetes usually dominate the structure and considered the most tolerant to stress associated with organic loading and low oxygen levels, thus effective as environmental indicator using ABC curve. The aim the study is to assess the environmental changes caused by Aquaculture activities using ABC curve of polychaetes assemblages as presented using the Shannon-Wiener (H') index at the studied areas. The results showed that approach to multivariate and graphical methods, especially using ABC curves can sensitively detect any environmental change, particularly changes in polychaetesassemblages, water quality and sediment over time.
