Nelapattu Bird Sanctuary (Lat. 13°49' N to 31°51' N; Long. 79°57' E to 59°15' E) is located towards west of East coast of Bay of Bengal and about 20 km west of Pulicat Lake near Sullurpet, Nellore District, Andhra Pradesh. It is one of the biggest pelicanery having approximately 1500 pelicans (Pelecanus philippensis) breeding and roosting. It is also an ideal roosting and breeding for long distant and local migrant birds. Vertical gradient and resource partitioning of migratory birds on Barringtonia tree in Nelapattu Bird Sanctuary is being observed. A gradual and natural domination of open bill storks is observed over a period of time. A review on management of Nelapattu Bird Sanctuary is described for ecological sustainability which include irrigation water management, deweeding and prevention of algal bloom, Prosopis juliflora plantation for roosting of birds, plantation of Subabul trees for procuring nesting material. Feeding of st Krishna river water to last only up to May/June 1st week only to avoid stabilization of new summer birds which might compete for space. A statistical relationship worked out between monsoon rainfall and pelican migration.Keywords

Milkfish (Chanos chanos) is one of the most important brackishwater finfish species being cultured in Southeast Asia. Natural milkfish fry occur along the southeast coast of India in fairly large numbers during the months of March-June and October-November. Present study emphasizes the seasonal variation and distribution of milkfish along the southeast coast of India. Milkfish culture has to be economically competitive compared to shrimp and other fish culture which do not contribute to local food supply. Annual total production from the Philippines, Indonesia, and Taiwan has been exceeding 0.5million tons since 2009. The industry has relied on wild-caught milkfish fry, which is unpredictable, until hatchery fry became available in 1987. This paper compares the collection of wild seed near mandapam area as well as production costs in cage. Milkfish eggs (1.1-1.2 mm in diameter) and larvae (3.5 mm at hatching) are pelagic and stay in the plankton for up to 2-3 weeks. This would be a good source of income to coastal fisherfolk in Mandapam.Keywords
