Looking at national news, the ongoing battle to eradicate European carp from Tasmanian lakes is coming to an end after 25 years with less than 20 of the pest fish remaining.

The Inland Fisheries Service, or IFS, director John Diggle says it has been a “long war” and tedious mission that cost millions of dollars to eradicate the carp because each female can lay up to 1 million eggs and the prolific breeder has no natural predators.

Mr Diggle says “[they] had big concerns for the waterways” after the carp had spread through the Murray-Darling Basin.

The fish was initially discovered in 1995 in Lake Crescent, then found in Lake Sorell soon after, and the IFS believes Lake Sorell, which is located in the state’s Central Highlands, will be carp free by next year.
