CA AB504

Prohibits hatchery production and stocking of transgenic species of salmonids, with "transgenic" defined according to California Code of Regulations Section 1.92 as it read on May 14, 2003.

Makes it unlawful to spawn, incubate, or cultivate any transgenic species of finfish belonging to the family Salmonidae anywhere in California, and prohibits research or experimentation for commercial production of transgenic salmonids.

Authorizes the Department of Fish and Wildlife to issue permits for medical or scientific research on transgenic finfish by accredited California academic institutions or private entities, provided research occurs in closed systems eliminating escape risk and the department notifies the Joint Committee on Fisheries and Aquaculture at least 30 days before permit approval.

Extends the sea cucumber permit program sunset date from April 1, 2015 to April 1, 2020, with repeal moved from January 1, 2016 to January 1, 2021.

Declares no state reimbursement is required for local agencies as the bill creates new crimes and changes penalty definitions.
