The University of Tasmania in collaboration with Inland Fisheries Service (IFS) and NRM North has recently secured research funding from the Australian Research Council (ARC) to genetically control Gambusia. The Gambusia is a pest fish of national concern and in Tasmania it is currently restricted around the Tamar Island Wetland Reserve (TIWR) in the Tamar estuary. The Gambusia was introduced into Australia more than 100 years ago to combat malaria. However, it was ineffective in controlling mosquito populations, but has bred prolifically and caused extensive damage to the native aquatic fauna – eating endangered fish and frog larvae and also the adults. The funding is a significant leverage to the IFS resource commitments (1:4), towards addressing this important fisheries management challenge. UTas will be the lead research agency with contributions and participation form IFS, NRM North and volunteer groups at TIWR. The outcomes of the project will be of national and international significance.
Inland Fisheries Service presents work at the Australian Society for Fish Biology (ASFB) and the Australian Society for Limnology (ASL) joint congress in Darwin
The 2014 ASFB and ASL congress was held from the 30th June to the 3rd of July at the Darwin Convention Centre. Delegates from universities, environment, and fisheries bodies around Australia attended the conference. There were 237 oral presentations, including two given by fisheries biologist Jonah Yick and senior fisheries management officer Rob Freeman, both representing the Inland Fisheries Service. The presentations were titled “The eradication and management of European carp from two large freshwater lakes in Tasmania” and “Extinct habitat, extant species: lessons learned from conservation recovery actions for the Pedder galaxias (Galaxias pedderensis) in south-west Tasmania, Australia”, respectively. Both of the presentations were well received by the other delegates, and highlighted the importance of managing threatened endemic fish species, as well as invasive pest fish.
Today (9 July 2014) the Inland Fisheries Service stocked Craigbourne Dam. The fish were kindly donated by Springfield Fisheries with some of the Atlantic salmon over five kilograms in weight. There were 310 Atlantic salmon ranging between two and four kilograms and 300 rainbow trout averaging two kilograms stocked into Craigbourne today. Anglers are reminded that there is a total daily bag limit of five fish. The minimum size is 300 mm in length but no more than two fish can be taken over 500 mm in length. The previous limit was two fish over 600 mm, note this change that will apply to all lakes that had the previous 600 mm limit.
Today (8 July 2014) the Inland Fisheries Service stocked some big fish into Lake Barrington. The fish were kindly donated by Springfield Fisheries and some were over five kilograms in weight. There were 225 Atlantic salmon ranging between four and five kilograms and 400 rainbow trout ranging between two and three kilograms stocked into the lake today. Anglers are reminded that there is a total daily bag limit of five fish. The minimum size is 300 mm in length but no more than two fish can be taken over 500 mm in length. The previous limit was two fish over 600 mm , note this change that will apply to all lakes that had the previous 600 mm limit.
IFS staff recently installed a marker buoy on a navigation hazard at Bradys Lake. The tree stump is partially or completely obscured at medium to high lake levels and represented a significant hazard due to its proximity in a line between the boat ramp and the Whitewater. Staff took advantage of a low lake level to attach a red marker buoy fixed by cable to the stump so it is visible at all lake levels.
With the onset of winter, the carp management team has diverted their efforts toward the planning and preparation of gear and equipment for the upcoming season in spring. So far 450 m of gill net has been repaired, with another 1000 m to go, as well as dozens of fyke nets which require checking and repairing to ensure optimal performance. A further 9 km of gill net is on order and expected to arrive shortly. This coming season is even more important, with a large proportion of the male carp predicted to be become mature. Spawning prevention while removing the existing population will be the focus.
During the third week of June 2014, Chris Wisniewski, Section Manager from IFS, attended the general meeting of the Tasmanian Fly Tyers Club to inform the group on the status of carp in Lake Sorell. The presentation was well received, with many of the club members having fished Lake Sorell before the arrival of carp. It is hoped that carp will be eradicated from this lake in the next few years enabling it to be reopened allowing many keen fishermen to get back to what was a highly valued trout fishery.
Anglers Alliance Tasmania and IFS have jointly funded the construction of a parking area on the western side of the Mersey River at Latrobe as part of the Mersey River Anglers Access project. Previously anglers had to park on the narrow verge on the busy B19 (Frogmore Lane) to access the western side of the river. In consultation with local landowners, Latrobe Council and DIER, AAT and IFS have jointly funded the construction of the car park for up to six vehicles. This will provide a welcome relief for the many anglers who like to fish this popular and productive stretch of the Mersey particularly early in the season when sea run trout are a focus.
As part of the Hydro Tasmania and MAST jointly funded navigation lights project a light has been installed on the Hydro Tasmania pump house at Arthurs Lake. The light has been installed on the eastern extremity of the pump house structure and is visible from all angles across the majority of the Blue Lake side of Arthurs Lake. IFS would like to thank Hydro Tasmania and MAST for making this installation possible and their ongoing commitment to improving boating safety on inland waters.
Mrs Barbara Martak together with her daughter Karen presented a mounted brown trout caught by her husband Jo in February 1986 at Little Pine Lagoon for inclusion as an exhibit at the Salmon Ponds Museum of Trout Fishing at Plenty to Deputy Director Tony Wright. Mrs Martak also included the story as related of the hunt for this beautiful specimen. “Tale of the 12 lb Trout While cleaning a couple of small brown trout on the banks of the Little Pine Lagoon, I saw a shadow dart in and near me. When i later stepped into the water to rinse out my two niced sized fish, was surprised to notice all the innards were taken. Towards evening I walked along the shoreline, but there was no sign of a fish of any size moving about. Next morning however he was there again and he was huge. I set my rod up with a New Zealand fly “Red Setter” which resembled the colour of the innards and no sooner started casting when the hit came. I had no idea how big it was , but I couldn’t fit in the the net and was pretty sure it was a ten pounder. What a great days fishing.”
