This was conducted to assess whether the feeding programme would adversely affect the local benthic environment, the survey focussed on measuring key indicators of organic enrichment. To do this, a range of sediment physicochemical parameters were characterised using benthic cores and sledding methods. Parameters included: sediment grain size, sediment organic content, sediment colour and smell, and redox potential of surficial sediment,and also biotic features including: the composition of animal communities living upon and within the sediments, and the distribution and abundance of macroalgae. This report describes the survey undertaken 8 months after the commencement of the fish feeding activity. Benthic and sediment data from 7 sites have been processed, checked, analysed, and summarised in the client report. Previous reports in this time series are: Brown, S. N. (2014a).

This report compares the 2015 results with those obtained in the Baseline Survey (undertaken in 2014) to assess changes in the estuarine benthos spatially and temporally following an experimental fish feeding operation in Nelson Haven.
