ABSTRACT: Community structure of fish in relation to environmental variation was investigated in Nanji Islands National Nature Reserve (NINNR). In order to test this relationship, we delineated 25 survey stations with bottom trawling and measured environmental variables. Samples were taken from November 2013 (autumn), February 2014 (winter), May 2014 (spring) and September 2014 (summer). We found a very strong correlation in space and time between temperature and salinity; abundance and biomass in winter; depth and DO in summer then a strong correlation was found respectively between temperature and biomass; salinity and biomass in winter too and finally a moderate correlation between depth and biomass in spring, (P-value
