The Legislature finds and declares that:
(a) The central California nearshore gill and trammel net fisheries for California halibut (Paralichthys californicus) and white croaker (Genyonemus lineatus) and the use of gill nets in these fisheries are expanding at a rapid rate.
(b) The incidental take of certain species of seabirds and marine mammals in set gill and trammel nets could be increasing to a level which may be adversely impacting the viability of the populations of nontarget species.
