Assessing benthic habitat ecological quality using four benthic indices in the coastal waters of Sanshandao, Laizhou Bay, China

Evaluation of the ecological quality status (EcoQs) of marine ecosystems is significant for environmental protection and management. In this study, the sensitivity/tolerance-based indices AMBI, M−AMBI and BENTIX and feeding evenness index jFD (feeding-based) were first used to assess the benthic eco...
