Resource or Project Abstract
The extent of the influence of salmon farming on the environment and on the uptake of particulate and dissolved effluents by benthic organisms was assessed using community structure and stable isotope analyses. Sediment cores were collected in 2 directions: perpendicular and parallel to the main residual current, 0, 25 and 200 m from 2 salmon farms (Millstone and Cranford) located in Mulroy Bay, Ireland. In addition, artificial substrates were placed for 2 mo at 1 m depth 0, 25 and 200 m from one farm to trace the uptake of farm-related nutrients by fouling organisms. The extent of measurable change in benthic communities (abundance, diversity, structure, trophic composition) depended on residual current direction. Intraspecific variation in isotopic values in benthic invertebrates was mostly explained by distance from cages. Organisms collected at impacted sites exhibited a shift in isotopic composition towards that of farm wastes. A shift in δ13C was observed in several invertebrates, including the polychaetes Malacoceros fuligi nosus and Nephtys hombergii, Nematoda and the anemone Anthopleura balii. Fouling communities collected on artificial structures, mainly composed of the tunicate Ascidiella aspersa, showed higher δ15N values at fish cage sites compared to sites 200 m away. The study demonstrated that fish effluents were assimilated and became food sources for several organisms.

| Lineage information about this project or dataset |
| The SIMBIOSYS Project investigated the impacts that human activity have on biodiversity and ecological functioning, and the associated benefits of biodiversity to human society, that is, ecosystem services. Three expanding sectors of enterprise were addressed in the project: (i) the cultivation of bioenergy crops; (ii) the landscaping of road corridors; and (iii) the aquaculture of sea-food. Field-based studies quantified biodiversity at the genetic, species and habitat levels under current commercial regimes, compared with traditional practices, and investigated ecosystem service delivery in all three sectors. The SIMBIOSYS Project has been a four-and-a-half-year research effort, involving six leading academics in four institutions, six PhD students, eleven research assistants at graduate and postdoctoral level, more than twenty MSc and undergraduate students and many other academic collaborators, both in Ireland and overseas. |
