dc.description.abstractThe anthropogenic discharges of inorganic nutrients impact water quality, affecting the macroinvertebrate assemblageand food safety. The main objective of this study was to examine the seawater quality and macroinvertebrate dynamics inmuddy habitats of Buenaventura Bay, Colombian Pacific. Macroinvertebrates were captured using artisanal trawl nets duringdifferent seasons and along four sampling sites. Multivariate analyses (canonical correspondence analysis and generalizedadditive model) were used to assess the effects of variations in nitrite, nitrates, phosphate concentrations, and phys-icochemical variables (salinity, pH, dissolved oxygen [DO], temperature, and total dissolved solids [TDS]) of water on themacroinvertebrate assemblage. Richness was the highest at sites with high salinity and temperature and low concentrationsof nitrites and TDS. The densities of the commercial shrimp species Xiphopenaeus riveti and Rimapenaeus byrdi were thehighest at sites with higher DO and alkalinity, and lower nitrate concentrations. The swimming crab Callinectes arcuatus wasdominant at sites with low water quality. In summary, in the transitional season and at the inner sites of Buenaventura Bay, itwas observed the lowest water quality due to high nitrate concentration. High nitrate concentration was highlighted as themain anthropogenic factor that could decrease the capture of target macroinvertebrate species for food and livelihoods ofartisanal fishermen and their families. Thus, macroinvertebrate communities may be vulnerable to increased inorganicnutrient inputs, which could affect estuarine water quality and ecosystems services.
