Allochthonus inputs into seasonal reservoirs: "Ornithological eutrophication" as a source of nutrient enrichment

Gunaratne, A.M.; Jayakody, S.; Amarasinghe, U.S. (Sri Lanka Association for Fisheries and Aquatic Resources, 2010)

The current study evaluates a lesser known allochthonus nutrient input into water sources, i.e. accumulation of bird faecal matter. Asian Open bill (An8stomus oscit8ns) population is increasing in Sri Lanka and due to ...
Diurnal variation in the feeding patterns and food preferences of Dwarf panchax (Aplocheilus parvus)

Fernando, G.K.A.W.; Jayakody, S.; Wijenayake, W.M.H.K.; Galappaththy, G.N.L.; Yatawara, M.D.M.D.W.M.M.K.; Harishchandra, R.D.J.; Wanninayake, W.M.T.B.; Deniyage, S.L. (Sri Lanka Association for Fisheries and Aquatic Resources, 2015)

The food and feeding studies of fish are useful to explore the possibilities of using them for various purposes such as aquaculture and biological control of problematic organisms. In the current study feeding patterns and ...
The feeding patterns and food preferences of Aplocheilus parvus: a potential biological control agent for malaria?

Fernando, G.K.A.W.; Jayakody, S.; Wijenayake, W.M.H.K.; Yatawara, M.; Harishchandra, R.D.J.; Deniyage, S.L.; Galappaththy, G.N.L. (Sri Lanka Association for Fisheries and Aquatic Resources, 2012)

The ultimate aim of Anti Malaria Campaign is to eliminate indigenous malaria from Sri Lanka. Better environmental and economic benefits could be achieved by the use of indigenous fish species compared to chemical ...
Fluctuations in Avian Distribution and Diversity in Anavilundawa Ramsar Sanctuary

Gunaratne, A.M.; Jayakody, S.; Amarasinghe, U.S. (Department of Wildlife Conservation, 2014)

Many of the seasonal water bodies in Sri Lanka harbour substantial numbers of aquatic birds. Local aggregation of water fowl during communal roosting and colonial breeding results in substantial inputs of nutrients into ...
“Ornithological eutrophication” as a source of allochthonous nutrient enrichment in Anavilundawa reservoir, Sri Lanka

Gunaratne, A.M.; Jayakody, S.; Amarasinghe, U.S. (2015)

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 ...
