Benthic community response to sediment organic enrichment by Mediterranean fish farms: Case studies

Performance measures and models for open‐water integrated multi‐trophic aquaculture

“…The bulk of settleable organic solids from fish cages (faeces, waste feed) and shellfish culture typically deposit in close proximately(Tomassetti et al . ). Although, farm‐based organic material can be expected to transit to hundreds of metres away, depending on depth and current dynamics (Bannister et al .…”

“…This is a common approach in the detection of aquaculture effects (e.g. Modica et al 2006;Chang et al 2014;Jansen et al 2016;Tomassetti et al 2016;Broch et al 2017;Chen et al 2017). Some open-water IMTA studies that have applied this approach include those with blue mussels (Mytilus edulis) near salmon (Chinook, Oncorhynchus tshawytscha; Coho, Oncorhynchus kisutch; Atlantic salmon, Salmo salar) farms (Taylor et al 1992;Cheshuk et al 2003), Pacific oysters (Crassostrea gigas) near Chinook salmon (O. tshawytscha) cages (Jones & Iwama 1990;Blouin et al 2007), European flat oysters (Ostrea edulis) and Mediterranean mussels (Mytilus galloprovincialis) at sea bream (Sparusaurata) and sea bass (Dicentrarchus labrax) cages (Navarrete-Mier et al 2010), seaweeds (Gracilaria spp.)…”

“…Diet acquisition for co-cultured species in IMTA systems is a function of ambient dietary concentration, access, diet composition, culture density, diet persistence, rate of supply, particle size and particle settling rate. The bulk of settleable organic solids from fish cages (faeces, waste feed) and shellfish culture typically deposit in close proximately (Tomassetti et al 2016). Although, farm-based organic material can be expected to transit to hundreds of metres away, depending on depth and current dynamics .…”

Spatio-Temporal Dynamics of Benthic Macrofaunal Communities in Relation to the Recovery of Coastal Aquaculture Operations Following the 2011 Great East Japan Earthquake and Tsunami

“…Rehabilitation of coastal aquaculture therefore attracted considerable interest from both marine scientists and policy makers. Recent studies demonstrate varying, but often negative, effects of aquaculture on the environment through changes in the physical, chemical, and biological attributes of sediments below and the water column around aquaculture installations (e.g., Tovar et al, 2000;Borja et al, 2009;Forchino et al, 2011;Sarà et al, 2011;Farmaki et al, 2014;Tomassetti et al, 2016). Most studies demonstrate reduced impacts of shellfish aquaculture than finfish aquaculture because shellfish are grown at comparatively lower intensity and require no external feed (Shumway et al, 2003;McKindsey et al, 2006;Weise et al, 2009).…”

“…Benthic macrofauna have long been used as indicators of environmental health and trends in coastal marine ecosystems (Borja et al, 2009;Forchino et al, 2011;Tomassetti et al, 2016). We therefore investigated spatio-temporal dynamics of benthic macrofaunal community structure in relation to changes in multiple environmental factors including the rehabilitation of coastal aquaculture facilities in Onagawa Bay following the 2011 Tohoku earthquake and tsunami.…”
