“…This could be due to the high variability in the composition, structure and amount of the extracellular polymeric substances in different microorganisms that produce it (Fig 1 B Tago and Aida, 1977;Decho, 1994). The seasonally different species composition of the biofilm community may have led to different polysaccharide contents (Riedel et al, 2007;Yucel-Gier et al, 2008). …”

“…The impact of fin fish aquaculture has been widely reported in the benthos, where common degradation patterns have been observed (Kalantzi and Karakassis, 2006), since the seabed is able to record possible detrimental effects to the environment over long periods of time (Danovaro, 2003). In the water column however, the effects are less obvious (Neofitou and Klaoudatos, 2008), and any differences in the measured parameters are usually more influenced by seasonality than aquaculture wastes (Pitta et al, 1998;Yucel-Gier et al, 2008). Indeed, water column parameters are often not correlated with the extent of benthic impact.…”

The structural, trophic and element accumulation changes in the biofilm community due to organic matter enrichment, eutrophication and metal contamination derived from fish farming were studied. The biofilm biomass, polysaccharide content, trophic niche and element accumulation was quantified along an environmental gradient of fish farm wastes in two seasons. Biofilm structure and trophic diversity was influenced by seasonality as well as by the fish farm waste load. Fish farming enhanced the accumulation of organic carbon, nutrients, selenium and metals by the biofilm community. The accumulation pattern of these elements was similar regardless of the structure and trophic niche of the community. This suggests that the biofilm communities can be considered a reliable tool for assessing dissolved aquaculture wastes. Due to the ubiquity of biofilms and its wide range of consumers, its role as a sink of dissolved wastes may have important implications for the transfer of aquaculture wastes to higher trophic levels in coastal systems.

“…The knowledge about the plankton response to nutrient enrichment from the Mediterranean fish farms comes from a limited number of studies (Pitta et al . , ; Pitta, Apostolaki, Giannoulaki & Karakassis ; Dalsgaard & Krause‐Jensen ; Yucel‐Gier, Uslu & Bizsel ; Pitta, Tsapakis, Apostolaki, Tsagaraki, Holmer & Karakassis ; Sarà, Lo, Sanfilippo, Pulicano, Cortese, Mazzola, Manganaro & Pusceddu ; Tsagaraki, Pitta, Frangoulis, Petihakis & Karakassis ). Majority of the aforementioned studies considered phytoplankton as the only potential consumer of nutrients.…”

Effects of fish farming on microbial planktonic communities in the middle Adriatic sea

et al. 2014

The effects of farming on planktonic microbial communities were investigated at the coastal sea bass/sea bream farm in the oligotrophic middle Adriatic Sea. Analyses of nutrients, chlorophyll a, cyanobacteria (Prochlorococcus), heterotrophic bacteria and nanoflagellates (both pigmented and heterotrophic) were carried out on samples taken during six seasonal cruises at different water depths. Farming activity increased the natural concentrations of some nutrients (ammonium, nitrite, phosphate, dissolved inorganic nitrogen) and changed their seasonal pattern. The values still remained typical for oligotrophic environments demonstrating no risk for eutrophication. Enhanced nutrient supply provoked an immediate increase in abundances of both autotrophic and heterotrophic microbial groups (except pigmented nanoflagellates) and chlorophyll a. The effect of farming was more visible for the heterotrophic microbial component. Results from this study reveal a potential common pattern of microbial response to farming in the oligotrophic environments. It also suggests the importance of heterotrophic microbial web in transferring the matter and energy released from the fish farms in nutrient poor environments.

“…Previous studies in the Mediterranean have addressed the effects of fish farming on water column chemistry and parasites (Papoutsoglou et al 1996), on seagrass (Delgado et al 1999), on nutrients and plankton (Pitta et al 1999, Yucel-Gier et al 2007, Neofitou & Klaoudatos 2008, Yucel-Gier et al 2008, Basaran et al 2010), on benthic community structure (Katavic & Antolic 1999, Karakassis et al 2000, Mazzola et al 2000, La Rosa et al 2001, Mirto et al 2002, Belias et al 2003, Klaoudatos et al 2006, Yucel-Gier et al 2007), on the dynamics of sediment accumulation beneath cages (Karakassis et al 1998), on the biological and geochemical properties of muddy and sandy sediments (Papageorgiou et al 2010), on the recovery process of benthos after cessation ) and on changes to wild fish assemblages (Dempster et al 2002, Machias et al 2004, Machias et al 2005). Most of the aforementioned studies have addressed the environmental impact of fish farming without investigating its spatial and temporal extent.…”

Spatial and temporal effects of fish farming on the benthic community structure at 2 fish farms in the Eastern Mediterranean were investigated between July 2004 and April 2005. In the area of each fish farm, 3 stations were sampled. At each station, sediment samples were collected for analysis of organic carbon, organic matter and benthic community parameters. There were statistically significant differences in organic matter and organic carbon among all stations. This impact seems to be only spatial, since 1-way ANOVA indicated no significant differences in organic matter and organic carbon between seasons for both farms. Furthermore, significant differences were found in species number, abundance and species richness among stations and seasons for one of the farms (2-way ANOVA). One-way ANOVA indicated that the significant differences, detected in the benthic community parameters of this farm, were spatio-temporal for species number, temporal for abundance and spatial for species richness. The spatial effect of fish farming on benthic community structure was present up to 50 m from the centre of cages on one farm and between 50 and 300 m from the other farm. Capitella capitata was the most dominant species at the farm sites, while Nephthys hystricis was the most dominant species at the control sites. In all cases, the benthic assemblages in the immediate vicinity showed symptoms of disturbance, but the spatial and temporal extent of this effect was less than one would expect considering the fact that the study area is located in a semi-enclosed gulf.
