Current status of the minke whales and conflicts of interest
Minke whales - the rorqual group of the family Balaenopteridae - are widely distributed and constitute an important major harvestable living resource of the sea. Recently, the Antarctic minke whale population has been estimated to be between 150,000 and 300,000. Populations being dynamic entities, t...

Minke whales - the rorqual group of the family Balaenopteridae - are widely distributed and constitute an important major harvestable living resource of the sea. Recently, the Antarctic minke whale population has been estimated to be between 150,000 and 300,000. Populations being dynamic entities, the size of the minke whale population has been changing. Currently , the minke whale population in the Antarctic has been claimed to have increased considerably. However, the minke whale stock arriving off Brazil could be regarded as only a small discrete unit of breeding stock and an integral part of the Brazilian natural resource. Data analysis based on the past 21 years shows that this stock is relatively in a steady state, but with only a few annual fluctuations which are around a constant mean value; and these departures are attributable both to environmental conditions and the local operational parameters.
