ABSTRACT
Time series and simple correlation analysis have been
used to study time trend and relation between catch and
corresponding effort (fishermen & boats) as well as gross
fish income in lake Burollus during the period of 1962-1984.
Fish catch in the lake is estimated to increase over
time. Annual fish catch has been fluctuated during the
period of study. Coefficient of variation was equal to ~bout
10 X. Total number of boats has raised by about 14
X.however. number of fishermen has dropped by about 7 X.
Gross fish income has substantialy raised during the period
of study by about 1396 X.
No significant correlation has been observed between
fish catch from the lake and total number of fisherme~. On
the other hand very highly significant correlation was found
between fish catch and productivity of one fisherman.
It is suggested to consider lake stocking by cleaning its
connection with the sea. The enumerators and other field
staffs should be raised through a series of training
programmes, and the requlations for fishing on the lake need
to be re-evaluated.
