An 8-week feeding trial was conducted to investigate whether dietary sodium butyrate (SB) administration alleviates growth reduction and enteritis of orange-spotted grouper ( Epinephelus coioides ) caused by high soybean meal (SBM) feeding. The control diet (FM diet) formulated contain 48% protein 11% fat. Soybean used replace 60% FM in prepare a SBM (HSBM diet). Sodium at 0.1%, 0.2%, 0.3% were...

Diverse anthropogenic activities including alteration of hydrological regime and agricultural development in the upstream river catchments modify structural components ecological roles species estuarine ecosystems. The present study compared diet, carbon (?13C) nitrogen (?15N) isotopic signals, trophic niches metrics redundancy predatory fish their potential phytodetritivore prey-fish between t...

The distributions of water quality parameters viz. temp, salinity, dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended substances (TSS), nutrients [NO -N, NO -N, NH -N, PO -P, SiO -Si, 2 3 4 4 4 total nitrogen (TN), total phosphorous (TP)] and Chlorophyll-a (Chl-a) were studied in the Mahanadi river and costal environment of Paradip in two different seasons i.e. post-monsoon...
