Scientific contribution

JARPN/JARPNII/NEWREP-NP

December 2017, Scientific contribution from JARPN/JARPNII/NEWREP-NP (pdf file)


The Japanese Whale Research Program under Special Permit in the North Pacific (JARPN) was conducted between 1994 and 1999. The JARPN had two main objectives: a) determine the stock structure of common minke whale, and in particular to investigate whether or not the “W” stock exists and if so to estimate mixing rates between “O” and “W” stocks, and b) determine the feeding ecology of the common minke whale in the North Pacific.


The International Whaling Commission Scientific Committee (IWC SC) carried out a workshop in February 2000 to review data and results of JARPN. The report of this workshop can be found in the following web site:

JARPNII started with two feasibility surveys in 2000 and 2001. The first full survey started in 2002. The objectives of the JARPNII are the following: a) feeding ecology and ecosystem studies (prey consumption by cetaceans, prey preference of cetaceans, ecosystem modeling); b) monitoring environmental pollutant in cetaceans and the marine ecosystem (pattern of accumulation of pollutants in cetaceans, bioaccumulation process of pollutants through the food chain, relationships between chemical pollutants and cetacean health), and c) stock structure of large whales (common minke whale, Bryde's whale, sei whale and sperm whale).


The IWC SC carried out a review workshop of the data and results collected by JARPNII in its first six years (2002-2007) in January 2009. The report of this workshop can be found in the following web site:

The IWC SC carried out a final review workshop of JARPNII in February 2016. The report of this workshop can be found in the following web site:

Since 2017 Japan started a 12-year long research program called New Scientific Whale Research Program in the western North Pacific (NEWREP-NP), which has two main objectives: a) Contribution to optimizing the establishment of a sustainable catch limit for common minke whales in the coastal waters of Japan, and b) Contribution to the RMP/IST for North Pacific sei whale.


A mid-term review of NEWREP-NP will be carried out after the first years of surveys are completed.
