here is a response i got fromthe DPI regarding the hawkesbury river
I have forwarded your email to the relevant parts of the Department, I am still waiting for a response on the second part of your question - ie "I would appreciate a response regarding your stance on the water quality of the river regarding sewer run off and the actual affects." but in response to the first question (I would appreciate a response regarding the future possibility of a commercial fishing ban in the Hawkesbury river ) this response has been forwarded to me from Recreational Fisheries branch.
Thirty Recreational Fishing Havens (RFH) were created along the NSW coastline in 2002, following extensive public consultation and the buy out of commercial fishing businesses to offset the reduction in the available fishing grounds. However, there are no current plans to establish new recreational fishing havens in the Hawkesbury River.
I can advise that a detailed environmental assessment was prepared for the Estuary General Fishery (including the Hawkesbury River) in accordance with NSW and Commonwealth law. The resultant Fishery Management Strategy specifies the overall goals and the operational rules for the fishery. The fishery is primarily managed through limiting the level of commercial fishing effort by controlling commercial fishing gear, as well as operational times and areas. The strategy contains a range of performance indicators and trigger points designed to alert I&I NSW to any undesirable changes in the fishery. A copy of the strategy is available on the I&I website.
I will continue to chase up some information regarding your other question.
