Pleasing Survey Results from the Clyde River

The Inland Fisheries Service recently conducted its annual survey to monitor the containment of carp within lakes Crescent and Sorell on 8 March, and the results were pleasing for two important reasons.

 
Annual electrofishing survey of the Clyde River finds no carp and plenty of trout
The Inland Fisheries Service recently conducted its annual survey to monitor the containment of carp within lakes Crescent and Sorell on 8 March. It was conducted using electro-fishing equipment downstream of Lake Crescent in three short sections of the Clyde River from Bothwell to Hamilton.

The survey results are pleasing for two reasons. Firstly, no carp were found. Actually, carp have never been discovered downstream of lakes Sorell and Crescent in these surveys since carp were first discovered in Lake Sorell in 1995. This demonstrates that the Service’s number one carp management strategy of containing the pest species to this lake system continues to be successful.


The second point of interest was the significant increase in the number of brown trout caught in the survey, compared with previous years. All these fish were in excellent condition and ranged in weight from 0.5 to 1 kg.

Moderate river flow rates were observed in all of the survey locations. Hence increased flow rates which have persisted since last season as a result of the drought breaking rains, are likely to be a key reason for the improvement in the river fishery.
