David Muirhead Mixed good and bad algal species IE the baddies are opportunistic and excessive due excess nutrients in catchment runoff,resulting from coastal settlement and altered land use.

David Muirhead These are spectacular and quite big reef fish which are probably not seen by divers and snorkelers these days as often as was the case for the first half of my diving life.We do still see them,but less often at the shallow inshore limit of their usual depth range and particularly if one is diving anywhere near major metropolitan coastal sites such as greater Adelaide.You don't have to be a genius to ponder the connection between targeted spearfishing plus commercial fishing both targeted and as by catch,and the above anecdote They are very good eating and very easily speared or trawled in many regions in southern Australia from close inshore right out to deep shelf waters,generally in moderate to high energy rock reef areas but also found over soft bottom if there is good invertebrate habitat e.g. sponges razor shells and the like.

David Muirhead at time I took this pic ,at a guess around 1997-9,the background orangelined bullseye(Pempheris ornata)was only described to Genus level,not species,yet it's very common here in inshore SA!!!

David Muirhead This species which is sole member of its genus is occasionally observed in stationary line up formations like this,perhaps so that while a school is resting the group has optimal survival via rapid communication if one detects a predator threat.

David Muirhead The black stained parts on most of these shells almost certainly represent the frequent near shore dredging events (now completed) during construction of the desalination plant a few kilometers south of Brighton Adelaide.Metropolitan Adelaide 's coast has a net long shore sand and silt movement from south to north which has accelerated since European settlement due loss of dunes via housing,sea grass loss due pollution,and other impacts.
David Muirhead Hmmm....

David Muirhead I think this shot was actually taken at Rapid Bay jetty but have not checked my old dive log book to confirm that detail -Dave the photographer.

David Muirhead Resulting from,in all probability is my personal opinion,unusually heavy and sustained or recurrent autumn rain in the catchments of our two big gulfs which lowered the pO2 throughout the water column to critically low levels for too many days.
David Muirhead Larger fish and small site attached bottom dwelling sharks and rays also succumbed,either from hypoxia or associated starvation due death of usual prey species.
