- Abstract
Selectivity of Amblygaster sirm by gill nets of seven mesh sizes ranging from 2.3 to 3.8 cm stretched mesh was studied for a period of 12 months in the coastal waters off Negombo on the west coast of Sri Lanka. The size range of fish caught was 9.0- 22.0 cm. Selection by mesh sizes smaller than 3.0cm was towards the lower and of the selection curve.
