Description The Government of India Deep Sea Fishing Station at Bombay and the
Offshore Fishing Stations at Veraval, Mangalore, Cochin, Visakhapatnam and
Tuticorin have been employing in the exploratory fishing operations different
types of power vessels which vary greatly in their gross tonnage, net tonnage,
brake horse power, length of body, draught etc. even though most of them
use more or less the same or similar types of otter trawls. It is well known
that, suitably geared a larger boat would generally bring about a greater fishing
mortality than a smaller one in a unit amount of time when fishing in the same
ground. The capacity of a vessel to catch more or to catch less as compared
with another vessel is independent of the density of the population and is
related in some way to the makeup of the vessel itself. In computing catch
statistics of different vessels, 'standardisation of fishing time according to their
fishing powers' (Beverton and Holt 1957, P. 172) being essential, the present
work has been attempted based on available data from the exploratory fishing
operations of the vessels viz-, 'Jheenga', 'Bumili' and 'Meera' from Bombay.
