The Indian tuna fish haul is at its
lowest level for twelve years, Reuters has
reported.
During the first four months of 2007, the total weight of
fish landed was put at 75,000 tonnes, some 36 per cent lower
than the catch during the same period in 2006.
‘The biggest question is whether this decline is a
consequence of environmental conditions, or whether somehow the
catches of the past few years have affected the population
levels,’ said the head of the Indian Ocean Tuna Commission,
Alejandro Anganuzzi.
Previously, declining catches have been attributed to tuna
diving deeper to escape the warmer surface-level sea
temperatures brought about by global warming. Now a question
has been raised as to whether the large catches of the previous
four years have led to a serious decline in stocks.
‘Probably in a year or two we will have all the data for our
computer modelling to assess the current situation,’ said
Anganuzzi, whose organisation is examining the reasons behind
the decline.
