Assessing Ecological Impacts of Shrimp and Sewage Effluent: Biological Indicators with Standard Water Quality Analyses

Mapping anthropogenic nitrogen through point sources in coral reefs using δ15N in macroalgae

“…Natural stable N isotopes ( (McClelland et al 1997, Fry 1999, Jones et al 2001. It has been suggested that δ 15 N values of coral tissue and macroalgae on coral reefs be used as biological indicators of anthropogenic N assimilation and for evaluating timeintegrated effects (Sammarco et al 1999, Heikoop et al 2000, Gartner et al 2002, Umezawa et al 2002b that are missed by simply monitoring N concentrations in the water column.…”

Use of stable isotopes to investigate dispersal of waste from fish farms as a function of hydrodynamics

“…Stable isotopes appear to be a promising tool for assessing patterns in dispersal of waste from fish farms (McGhie et al 2000, Jones et al 2001, Burford et al 2003, Sarà et al 2004, Vizzini & Mazzola 2004. Hobson (1999) argued that stable isotopes are the most powerful tools available to trace organic matter for several fields of ecological research, and others have recommended their use in pollution studies (e.g.…”

Spatial and Temporal Variations in Phytoplankton Abundance and Species Diversity in the Sundarbans Mangrove Forest of Bangladesh

“…Nitzschia longissima and Protoperidinium were also abundant throughout the area. These are opportunistic and indicator species of shrimp farm effluents [24,47].…”
