Title: On the Nature of the Selective Fishing Action of Longline Gear 
Author: Brock, Vernon E.

Citation: Brock VE. 1962. On the nature of the selective fishing action of longline gear. Pac Sci 16(1): 3-14.
Abstract: Fishery biologists have, thanks to the magnitude
of sampling provided by commercial
fisheries, a better quantitative understanding of
the populations with which they are concerned
than do biologists interested in the quantitative
aspects of other marine organisms. However,
fishery biologists must be aware of bias that may
be introduced by the sampling mechanism, the
fishing apparatus. Fishing gear may be more
effective in the capture of fish of some sizes or
in some areas or seasons. If the nature of the
bias is known allowance can be made for it,
and its character may supply additional information
on the population of fish.
