Effect of dietary replacement of fishmeal with Chlorella vulgaris on growth performance, energy utilization and digestive enzymes in Macrobrachium rosenbergii postlarvae

The present study was conducted to assess the growth promoting ability of Chlorella vulgaris on Marobrachium rosenbergii postlarvae. The experimental diets were prepared by fishmeal replacement with C. vulgaris at different levels (25, 50, 75 and 100%). The prepared feeds were offered to the M. rosenbergii postlarvae during 90 days in triplicate. At the end of the feeding experiment, survival rate, weight gain, specific...

Photosynthetic productivity and biomass of phytoplankton, in Lake Kuriftu, Ormia Region, Ethiopia

Photosynthetic productivity of phytoplankton and chemicals of the water column in Lake Kuriftu were studied from August 2005 to April 2006. The light-saturated rate of photosynthesis (Amax), which was positively and strongly correlated with phytoplankton biomass, ranged from 571 to 1136 mg O2 m-3 h-1. Biomass-specific rate of photosynthetic productivity at light saturation (Pmax) ranged from 18.78 to 33 mg O2 (mg Chl...
