  1. Watson Bay and dioxide level?

    The DPI recommends that for fish caught east of the harbour bridge, the recommended maximum consumption is five 150gm serves of trevally a month and one 150gm serve of tailor per month. The reason for the lower consumption level for tailor is that they are predatory fish that eat other fish and therefore accumulate dioxins that might be in the fish they eat. Dioxins are very dangerous and carcinogenic. Most of the doixins came from the old Union Carbide factory at Homebush. That's where they made agent orange - a lot of it ended up in the harbour (agent orange is the chemical they used to defoliate the jungles of Vietnam during the Vietnam war). That's why the DPI says you should not eat fish caught west of the harbour bridge. However you don't know where the fish have been or have been feeding - they might have just come in from the ocean and are completely free of dioxin, or they might have been born in the upper reaches of the Paramatta River, lived there all their lives and are now on their way out of the harbour.
  2. Shark/s in Pittwater

    I read a book once about the Australian navy seals who had some kind of training base at Taylors Point and these guys used to swim at night all the way up Pittwater and back (behind a boat). No mention of sharks but you would not get me doing that.
  3. Rock fishing - Brown's Rock

    If they won't take a bait on heavy gear, it sounds like trevally. Even moderate sized trevs can strip line from a light outfit. There do seem to be a lot of trevs out there near the entrance to the bay.
  4. I think you are correct Volitan, the dark bird looks like a Great Skua.
  5. In relation to the birds, I think The Producer is right, the first one is an albatross, but its called a black browed albatross. The darker bird is either a shearwater of some sort, possibly the common short tailed shearwater (aka mutton bird) or a great-winged petrel. Its hard to tell from the photo given there is no scale or sense of size to work off.
  6. Rec fishos please do this survey

    Don't be put off by the 20 minutes; it only took me 5 minutes...
  7. Dioxins west of harbour bridge

    For bream caught west of the bridge the recommended consumption level is zero. Fort bream caught east of the bridge its 150gms per month. Bream have one of the lowest consumption levels of the fish surveyed. Almost all other fish have much higher consumption levels. Dioxins is a very toxic group of chemicals. It came from the Union Carbide factory at Homebush, where among other things, they manufactured Agent Orange used in the Vietnam war.
