Trainers received an email on Thursday afternoon that work was going to start the next morning, as preparations continue for the Gold Coast Show to move to the Turf Club.

The email says the 2.75 hectare swamp area will be used for parking at the show and large race days but otherwise will be free for trainers to walk their horses the rest of the time. Continue reading »

News release from Biosecurity Queensland

Biosecurity Queensland and Toowoomba Regional Council have commenced a hunt for exotic pest turtles to protect local fauna, following Australia’s first discovery of a Chinese stripe-necked turtle (Ocadia sinensis).

The turtle was suspected of being dumped in Toowoomba’s Bicentennial Waterbird Habitat. 

Agriculture, Fisheries and Forestry Minister John McVeigh said a Chinese stripe-necked turtle plus nine non-native turtles were recently found during a recent fauna assessment. Continue reading »

The federal government’s approach for the Murray-Darling Basin Plan has shifted again, and now favours water-saving infrastructure over purchasing water rights. But is it the right move?

The new scheme proposes to cut the amount of water bought back from farmers by 200 billion litres — from 1,500 billion litres down to 1,300 billion litres. Continue reading »

The presence of the invasive lionfish in the Atlantic Ocean off the coast of Florida has prompted the state’s Fish and Wildlife Conservation Commission to take action. They’ve developed an app to control the nonstop growth of the lionfish population.

The lionfish possesses up to 18 needle-like dorsal fins that can deliver venom. It’s naturally defensive, and utilizes its camouflage and fast reflexes to capture prey. They can even harm humans and cause nausea and breathing difficulties with their venomous sting. The lionfish is native to reefs and rocky crevices, and they’ve made their way to Florida’s Atlantic coast 25 years ago. Continue reading »

If you didn’t make it along to the BCC Pest Fish Education Event you missed a fantastic morning out. The water might have been too cool for the Tilapia to bite but there were lots of other fish being reeled in. We were all impressed with the variety of native fish in the lake despite invasions from African Tilapia, American Gambusia and North Queensland Barred Grunter. There might have been a few fish that went back without being tallied but we did our best to count everything that came in – checkout the stats below. The barbless hooks provided by BCC ensured fish were able to be returned to the water in good condition. I still haven’t found out who managed to land gambusia while line-fishing…

DISEASED fish are again being pulled from the waters of Gladstone Harbour, almost two and a half years after the harbour was closed amid a contamination scare.

But while one fisherman has pulled in a load of fish he believed was diseased, wholesalers and authorities in the region have not reported a wider trend to date.

A disease outbreak in 2011 coincided with a major dredging project underway by Gladstone Ports Corporation, the first stage of which was completed last year.

That controversial project is currently the subject of a class action in Brisbane courts, with numerous Gladstone fishers and crabbers seeking compensation for lost grounds. Continue reading »

Marine reserves are a hot topic in Australia, with federal and state governments debating whether to allow recreational fishers to take fish from within their boundaries. But new research demonstrates that reserves can have a real benefit for marine ecosystems — by protecting coral reefs from floods.

We enjoy fishing; but we also appreciate that marine reserves have many positives. Yes, they restrict fishing in certain areas, but they have been shown to increase the numbers of catchable fish outside reserves.

Our study shows that reserves can also improve the resilience of the habitats that fish rely on. Without them, there would be fewer fish for everyone. Continue reading »

News release from Fisheries Queensland

The Field guide to common saltmarsh plants of Queensland is back by popular demand.

Field guide to common saltmarsh plants of Queensland by Louise Johns.

Field guide to common saltmarsh plants of Queensland by Louise Johns.

First printed in 2006, the popular publication is a valuable resource for local governments, students, teachers, community groups, fishers and people with an interest in Queensland’s coastal environment.

Author and senior fisheries biologist, Louise Johns, said the new and improved guide would help people to correctly identify key marine plant species in saltmarsh fish habitats and provide them with a greater appreciation of the importance of the saltmarsh environment.

“Marine plants, including saltmarsh vegetation, are protected in Queensland because of the valuable role they play in ensuring sustainable fish habitats and fisheries production,” Ms Johns said.

“Saltmarshes provide food for aquatic species and recycle nutrients.

“It is important that people are able to identify saltmarsh habitats and do their part to protect this integral fisheries ecosystem.

“The 76-page guide provides colour photographs, detailed descriptions, plant distribution maps and identification keys for the 32 most widespread saltmarsh species in Queensland’s coastal zone.

“It’s a simple, user-friendly guide that will make it easier to identify the species and provide a better understanding of this important ecosystem.

Original story by Dr Ben Diggles at Fishing World

ONE of the scourges of our tropical freshwater rivers, the Mozambique Tilapia (Oreochromis mossambicus, also known as the Mozambique mouth-brooder) was introduced into Australia in the 1960s as an ornamental fish.

Tilapia signage from Fisheries Qld.After being released into the wild (eventually most types of ornamental fish get released at some stage), O. mossambicus and two other species of closely related cichlids (the black mangrove cichlid Tilapia mariae and the redbelly tilapia (Tilapia zilii) have survived and established populations which have since spread into many new places, such that today they dominate many of Queenslands waterways.

These species have been listed in the top 100 of the world’s worst introduced species and they are regarded as one of the greatest threats to Australia’s native biodiversity, because they have several adaptations that combine to enable them to overwhelm native fish populations.

Firstly, tilapia females carry their eggs and larvae inside their mouths, providing protection which virtually ensures the survival of the next generation. They are also a particularly hardy fish, tolerant of poor water quality, pollution, low oxygen levels (which they tolerate by gulping air at the water surface) and a wide range of water temperatures (8- 42 °C). They can also survive in brackish water, which allows them to move between river systems after river flow events, and have rather flexible dietary requirements. When their favoured algae, animal waste and planktonic food items are scarce, they can readily adapt to alternative food sources, ranging from completely herbivorous to totally carnivorous (including cannibalism).
