Abstract
The variations noticed in the fishing intensity on an annual basis in the different
regions of the Vembanad lake arc discussed. Stake nets and dip nets acconnted for 72.48%
of the total landings; the former contributing to 53.14%. The contributions from gill nets,
seines, cast nets, line fishing and other indigenous fishing methods are respectively 10.15,
9.68, 3.49, 2.54 and 1.66%. Stake and dip nets are almost confined to the northern sector
(Cochin backwaters), contributing 57 and 20.7% respectively of the production. Seines
and gill nets acconnted for 8.5 and 8.3% respectively in this sector. In the southern sector
(Thannecrmukkom to Allcppey), the stationary gears are rarely noticed, the major part of
the landings being obtained from gill nets (34.34%), seines (24.67%) and cast nets (19.04%).
