 note = {Traditional spearfishing for slime-flounder (Microstomus achne)
in the coastal waters of Oma on Shimokita Peninsula, in northernmost
Honshu, Japan, was surveyed from an ecological point of view.
The results of the study are presented as follows.
1) The spearfishermen's fishing activities are limited by their
individual prowness.
2) There is a great variation in individual skills as revealed in the
difference of the catching rate per unit time, the total catch per
capita, the frequency and the type of errors, and the choice of
fishing gear.
3) Skills in spearfishing are regarded as adaptive in terms of
ecology, since the population of slime-flounder are selectively
exploited in terms of size and amount of catch; so that a constant
catch has been maintained.
4) Recent introduction of the longline and the gill net for slimeflounder
fishing has brought a rapid increase in the total yield;
however, smaller sized fish which used to be ignored have now
come to be exploited. As a result, a problem of over-fishing will probably occur in the near future.
5) Spearfishermen had to cope with technological changes. Few
could continue spearfishing; some changed from spearfishing to
the more mechanized, but less skillful longline and/or gill net.
Others were forced to abandon spearfishing and reduced to
small scale fishing such as octopus fishing and abalone spearing.
Only a few old fishermen continue to spear fish, utilizing their experiences from old days.
6) Technological changes in slime-flounder fishery show that the
skills are rapidly disappearing which had contributed to maintain
an ecological balance between the fishermen and the fish
population, as well as the traditional way of life in the fishing village.},
