Recreational fishing lobby group VR fish has done their part to ensure the continued decline of native fish populations by implimenting a mass release of the introduced predatory species of salmonid Salmo trutta morpha fario commonly known as brown trout.
Want to know about the environmental effects of this introduced fish species on populations of native aquatic inhabitants of our waterways?
Well you could go to the VR fish website for a heaping helping of half-truths, spin and lobbyist’s propaganda, or you could try a credible source.
Negative impacts of alien salmonids on native aquatic fauna (including fish, frogs, spiny crayfish), mainly through direct predation and to a lesser degree competition for resources, have been noted for over 140 years. Impacts on some faunal groups have been severe enough to eliminate entire populations and severely fragment species across their range. Despite these impacts, salmonid management is focused largely on providing improved recreational angling opportunities, whereas management of their impacts is almost non-existent. Management of the symptom of salmonid impacts, i.e., declining native species, begins only after native species have become imperilled.
In lay terms, we’ve known these fish wreck the rivers for over 140 years, no-one wants to do a bloody thing about it because all the money to be made selling fishing tackle, licenses, boats, outboard motors, bait and other miscellaneous crap to yobbos who like to go fishing, and it’s unlikely a bloody thing WILL be done about it until populations of native species have declined to the point where it’s too late to save them anyway.
