Nitrification of waste waters from fish-meal factories
Fish-meal factories generate waste waters with high chemical oxygen demand (COD), suspended solids (SS), fats and protein concentrations. After their treatment by anaerobic digestion, effluents with high ammoniaand organic-nitrogen contents and a fraction of residual COD are produced. A biological nitrification/denitrification process is proposed to reduce both the residual carbon and the nitro...

Replacement of fish meal by earthworm meal (Eiseniafoetida) in Siberian Sturgeon (Acipenserbearii) diet and its effect on growth performance, feed efficiency and carcass composition
A 12-week feeding trial was carried out to assess the effect of fish meal replacement by earthworm meal (Eiseniafoetida) on growth performance, feed efficiency and carcass composition of Siberian sturgeon (Acipenserbaerii). Fish with mean weight 21.32 ± 1.91 (mean ± SD) were fed with five experimental diets which 0% (Control), 10% (EWM10), 20% (EWM20), 30% (EWM30) and 40% (EWM40) of fish meal p...
