On the oil sardine fishery of the Mangalore zone duringthe years 1957-1963.

In the Mangalore zone extending from Malpe to Kasaragod, the season for oil sardine [Sardinella longiceps Val.) is roughly the same as in the Calicut area, viz., October-March. Work on the fishery of this zone was started in 1957. - The first season's study was of a preliminary nature but later the programme was expanded to include detailed observations at Ullal, an important centre near Mangalore, and regular visits to other fishing villages for collection of samples. During this investigation special emphasis was laid on catch trends environmental variations and size and age composition. The results for the period 1957-63 are presented here. The fishery of part of this zone for the years1925-52 has been discussed by Nair (1952).
