SUBMISSION BY ADRIAN PIERS: Crayfish and Tilapia

30 October, 2007

Re: Public Hearings: National Environmental Management Amendment Bill (36-2007)

Dear Ms. Albertina Kakaza,

Please accept this submission to the Portfolio Committee on Environmental Affairs and Tourism for inclusion on the agenda at the public hearings on the National Environmental Management Amendment Bill.

Freshwater invertebrates

1. The proposal that two species are removed from their present listing and placed in the list of EXEMPTED ALIEN SPECIES. These are Cherax tenuimanus, the Marron Crayfish and Cherax quadricarinatus, the Redclaw crayfish

As both these have been farmed historically with no detrimental effects for many years.

2. The proposal that two species are removed from their present listing and placed in the list of INVASIVE SPECIES FOR WHICH A PERMIT IS REQUIRED UNDER CERTAIN CIRCUMSTANCES. These are

Procambarus clarkii, the Red Swamp crayfish and Cherax destructor, the Yabby

Due to concerns of eradication and disease transmission

I would like to verbally give my reasons in briefly, but in more detail, with supporting evidence for the above at the Public Hearing.

Thanking you in advance, Yours sincerely,

Adrian Piers.
