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...

متن کاملReplacement value of hatchery waste meal for fish meal in the diet of laying Japanese Quail (Coturnix coturnix japonica)
A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...

fishing per somewhat longer voyage and more fish per day at sea and per ton of fuel. These two British pioneer experiments have indicated two possible ways of improving the exploitation of wide-ranging fisheries.
