long term impact is unknown
	
	
		Thanks Gary, the point "issues such as how quickly the ship can take its quota and the short term impact" may be issues such as how quickly the ship can take its quota and the long term impact is unknown. 
  Spear fishing is usually totally selective fishing, rod and line fishing is hopefully somewhat selective and we can generally release what we do not need or want. Reading the recreational tailor take in WA several years ago opened my eyes to what we can do where recreational fishers took more than the commercial take of tailor. If we could clearly work out the tonnage of the target fish in a manner which was both transparent and accepted then it would be more likely we could then assume/accept the by catch and localized impact. Remembering the ‘localized’ impact is from Sydney all the way around to Perth. 
  Remember  the Mulie or pilchard fishery collapse due to a disease in the last few years and the dramatic impact that had on fishing stocks across southern Australian. Lots of evidence at least some pilchards used for feed or bait spread this across the southern sea board. Few if any fishing boats have fished from Brisbane, Sydney, Hobart to Perth before. None would haul in the tonnage which got this ship kicked out of Senegal. I might be wrong and clearly some of the data I copied from others is a bit thin or off target.  To introduce this without a proper study of its impact is in my opinion both alarming and very short sighted.  Sure you will not join the traffic jam but your thought would not stop me from joining it sadly. Sadly as the snow looks like a lot more fun for a drive and a walk.
