Abstract
Ring seine, which is the major fishery of Kerala,
contributes 55.7% of the state’s total marine fish
production and contributes 21.31% of the total
marine landings of the country, out of which 73.4%
is of pelagic resources. Even small fluctuation in the
annual output of ring seine reflects on the total fish
production of the state. Two types of ring seine
systems are operating in Kerala, namely, mechanised
(fitted with inboard motors or IBM) and motorized
(operated with outboard motors or OBM). This
paper examines the growth and instability of fish
production from the ring seiners operating from
central Kerala, India during the period 2002-2011.
Time series data on daily landing from 36 fishing
vessels, including 27 mechanised and 9 motorized
ring seine units were used for the study. The results
reveal that there is a positive growth in the
production from the mechanised ring seiners while
the growth from the motorized sector has been
falling over the period under study. The overall
instability ranged from 36-38% and was more
prominent in motorized vessels.
