Mass aggregation of waterfowls for breeding, results in allochthonous nutrient inputs intoaquatic systems. This study evaluated accumulation of bird droppings as allochthonusnutrient input and its ﬂuctuations in Anavilundawa ...
A rationale for introducing a subsidiary fishery in tropical reservoirs and lakes to augment inland fish production: case study from Sri Lanka
