Voting is now open for the Fly Life Magazine‘s photo competition and all of the finalists have some cracking entries.
The plan was to head to the mid stretches of the Thredbo River in the Snowy Mountains to try and fool some foot-long brown trout into eating a dry fly. But after a short walk to my favourite stretch of water the rain had set in making it almost impossible to spot my fly. A change in tactics was needed, so I tied on a heavy double nymph rig and attached a subtle indicator to fish some deeper runs.
A quick post to give a bit of background on the PhD research I am carrying out at present, as always, questions, advice and constructive criticism is welcome.
The vast unknown: assessing the conservation of soft sediment fish diversity
Sand. That grainy stuff that covers vast swathes of the ocean floor. Although perhaps to the casual observer this habitat isn’t as exciting as coral reefs or seagrass meadows, delve a little deeper and you will discover that there is a whole lot happening out in the vast sandy stretches of the ocean. Sand or soft sediments cover most of Australia’s state and national waters and are heavily exploited by commercial and recreational fishing.
Surprisingly, there has been little research into fish ecology on these habitats, with most effort expended on assessing fish found on coral reefs, rocky reefs, estuaries and seagrass. For a habitat that is so heavily exploited, there is a serious and immediate need to determine the basic ecology of the fish species present, the effects of fishing and also to examine the success of conservation efforts in place. More than 70% of Australia’s marine protected areas cover soft sediments, yet to my knowledge, both nationally and internationally there have been no studies looking at the effectiveness of marine protected areas in conserving soft sediment fish.
My PhD aims to examine Continue reading
