 Klumov wrote to the central fisheries ministry complaining of how the Five-Year Plan quotas were not reflecting of the actual state of the whale stocks around the Kurils, and suggested a more rational approach to whaling and saying Plan quotas should reflect the condition of the whale stocks and not raw domestic production, but unfortunately his concerns were ignored.Indeed, towards the end of the 1950s the Kuril land stations (and to a great extent the Aleut as well) began increasingly taking under-sized whales, especially sperm whales, because of a great desire to meet production targets, despite rapidly depleting the area of whales.By the end of their operating periods, the majority of the catches in the Kurils region consisted of undersized whales.
