Prawning in Tasmania - oh yeah!

by Jamie Henderson
No matter where you are in Australia, pretty much every
saltwater based estuary environment you come across will
contain a species of prawn…..yes even in Tasmania.
I am often quizzed by tourists travelling through the North
East region about the subject as they notice lights in the water
during the dark nights over the summer months. Many are
amazed that we have prawns in Tasmania at all, but let me
assure you there are plenty here at the right time of year.
Successful prawning is an art, and for some groups of
people, an annual pastime that has been going on for decades
with secret spots, times and techniques guarded as closely as
the gold in Fort Knox.

When you have finished for the day, why not have a brag about the ones that didn't get away! Send Mike an article on your fishing (Click here for contact details), and we'll get it published here. Have fun fishing -

Hello everyone, I thought it would be a good time to introduce myself.

My name is Stephen Smith and I have been managing the website since May 2009.

It has been an epic journey of learning and discovery and I am indebted to Mike Stevens for his help, support and patience.

I am developing a new venture Rubicon Web and Technology Training ( ). The focus is two part, to develop websites for individuals and small business and to train people to effectively use technology in their everyday lives.

Please contact me for further information.

Once regarded as a trophy fishery, the status of Lake Crescent slowly declined after the discovery of carp (Cyprinus carpio) in 1995, and repeated extreme drought and low water levels caused a significant decline in trout populations. The establishment of carp in Lake Crescent not only posed a risk to the trout through the destruction of suitable habitat and decreased water quality, but also had the potential to outcompete the threatened Golden galaxias (Galaxias auratus).

As a result, Lake Crescent was immediately closed from the public in 1995 and intensive fishing strategies were implemented in an attempt to control the spread of carp. By 2007, only one carp was caught, and all evidence suggests this pest has been completely eradicated from this lake. Continued monitoring is still occurring, but so far no carp have turned up and things are looking positive. Lake Crescent was officially re-opened in 2005, but the number of returning anglers was minimal.

A combination of low water quality, as well as the reduced trout population is likely to have discouraged people from returning back to this lake. However all is not lost and Lake Crescent is continuing to show increasing signs of improvement. Since the extreme low water levels in 2008, the average total turbidity of Lake Crescent has improved considerably. This is likely to be a direct result of the dilution by clear inflows and some flushing of suspended sediments down the Clyde River.

Currently, the water quality of Lake Crescent is the best it’s been for the past 10 years (See Figure 1). The expected high water levels this coming season combined with flushing flows this winter, should contribute further to improving water quality in the lake and help speed the rate of recovery of the fishery.

What is even more exciting for anglers were the results of the annual carp survey conducted in March 2011. It turned up a healthy number of outstandingly conditioned brown and rainbow trout, ranging from 2-4kg. This should entice a greater number of anglers back to Lake Crescent this season. There is also a lot of clear water in the back marshes of the wetlands, providing ideal areas for anglers this coming season. These marshes harbour a range of food items for trout, from frogs and galaxiids to a variety of aquatic invertebrates.

The service is currently working to re-establish Lake Crescent as a trophy fishery through a conservative stocking program. In the past few months, 5000 diploid brown and 5000 triploid rainbow trout have been released to this water.

Taking into account the highly productive waters of the lake, it should not be long before these fish become worthy adversaries on light line! This boost in recruitment in conjunction with increased water quality and overall productivity is bringing Lake Crescent a step closer to its former glory.
