On 16 February 2018, the Minister of Environmental Affairs published Government Notices GN 112 and GN 115 in Government Gazette No. 41445, proposing amendments to the existing Alien and Invasive Species (AIS) regulations and lists under the National Environmental Management: Biodiversity Act (NEMBA). The proposed amendments included listing brown trout and rainbow trout as alien and invasive species. The notices called for public comments within 30 days. Notices were also published in various newspapers including the Star (21 February 2018), City Press and Sunday Times (25 February 2018). On 12 March 2018, Mr. Ian Cox, a member of the Federation of Southern African Flyfishers (FOSAF), submitted a detailed objection. The Consortium of Interested and Affected Parties also demanded withdrawal of the notices on 13 March 2018. FOSAF associated itself with these objections on 18 March 2018. The Minister extended the comment period twice (30 April and 22 June 2018) and published the amended AIS lists and regulations in September 2020. On 16 January 2019, FOSAF launched an application challenging the validity of the original notices. The commencement of the amended lists and regulations was subsequently extended to 1 March 2021, and the listing of trout species was suspended until further notice.
