In the recent years, the contribution from outboard sector is a major component
in the total marine fish production from the states of Kerala and Karnataka.
This is as a result of the introduction of crafts fitted with outboard engines for
propulsion in the mid eighties, which intensified and developed into a major
sector. The impact of this intervention is examined here by adopting two popular
time series methods used for intervention analysis. The first method is based on
seasonal ARIMA modeling and the second is based on regression modeling with
ARMA type errors. Quarterwise total marine fish landings in the two states
during 1960-2000 were used for the impact study. The analysis revealed that
for Kerala the model found suitable is seasonal ARIMA type model and for
Karnataka the feasible model was regression model with ARMA errors. Based
on the final estimated intervention models, the effect of the interventions was
estimateds as 2.26 lakh tonnes and 88 thousand tonnes per annum respectively
for Kerala and Karnataka.
