さあ！諸君！捕鯨問題だ！

>元々資源の豊富じゃない温帯セミを100年余りの間に7万頭以上も殺せば、そりゃ枯渇もするわ。
>まあ、アメリカ一国でセミを１００年に７万頭が大量じゃねえんなら、
>今時日本がナガスやザトウを千や２千頭/年とっても、全然心配要らんな。そ・う・だ・ろ？（笑）

オッさん100年に７万頭ての、気に入っちゃったみたいだねw
これ北大西洋、南大西洋、北太平洋、南太平洋、インド洋って
海域分けすると、北太平洋は全域で1万5244頭だから、日本の
沿岸捕鯨年間100弱より希薄だよ。

Appendix 12
AN ATTEMPT TO RECONSTRUCT THE CATCH HISTORY OF RIGHT WHALES IN THE AMERICAN
FISHERY, 1805-1909

P. B. Best

Note that these calculations were extensively reworked following the meeting and
supplemented with an independent analysis based on the catch per voyage (Best, in prep.,
'Estimates of the landed catch of right (and other whalebone) whales in the American
fishery, 1805-1909'; submitted to Fishery Bulletin). The tables given here should therefore be
considered only as a preliminary version prepared for the purposes of the meeting.

Table 1
Mean yield per whale for the US fishery. Values were calculated (except for the gray whale
where the value was taken from Henderson, 1972) from voyages listed by Townsend (1935)
on which only one species of baleen whale was taken (North Pacific right whales were
considered as a different 'species '). Only voyages on which ten or more individuals were
landed were included in the calculation. Production figures for each voyage were
obtained from Starbuck (1878) or Hegarty (1959) and include oil sent home or sold
abroad when known.
