A reminder that Lake Sorell remains closed for the 2014/15 angling season due to carp control activities. This is an extension of the closure from the previous seasons. INLAND FISHERIES SERVICE Inland Fisheries Act 1995 Notification of Closure of Lake Sorell. I, John Diggle, Director of Inland Fisheries, acting in accordance with Clause 3 of the Inland Fisheries (Delay or prevention of Spread of Controlled Fish) Order 2003 hereby advise that Lake Sorell is closed below its high water mark and access is totally restricted to all persons from Saturday 2 August 2014 until further notice unless otherwise authorised by me in writing. Further I hereby direct, pursuant to Section 152(4) of the Inland Fisheries Act 1995, that access by persons and the activities of such persons in and around Lake Sorell be restricted in accordance with the above notification. Dated Wednesday 30 July 2014. John Diggle Director of Inland Fisheries
This is the time of year many anglers look forward to, opening of a new angling season. Season 2014/15 opens Saturday 2nd August 2014. So many are asking where is the best place to go? This year the IFS has built new traps in the Central Highlands at Arthurs Lake. What this means to anglers is that there have been a lot more adult brown trout transferred to other water than previous years. Rather than waiting for fry to grow to takeable sized fish (minimum size for waters is 220 mm or 300 mm in most fisheries) these adults are ready to catch with all those transferred greater than 220 mm and most greater than 300 mm in length. Fisheries that have received the most benefits from these developments are; Bradys Lake with just under 10,000 stocked, Four Springs Lake with 2,700 stocked, Craigbourne Dam with 4,000 stocked, Tooms Lake with 2,300 stocked and Lake Leake with 1,800 stocked. There are many others that have received adult brown trout, as the list below shows. Penstock Lagoon was stocked with 2,000 adult brown trout that have been adipose fin clipped. This was to estimate the size of the brown trout population there but also provides some extra stocks for anglers to target opening weekend. During May to July period Lake Barrington, Craigbourne Dam and Brushy Lagoon all received Atlantic salmon in the 2-6 kg range. Craigbourne Dam and Lake Barrington also received some big rainbow trout averaging 2.5 kg. Lake Kara is planned to receive Atlantic salmon and adult rainbow trout prior to the season opening, watch this website for details. It is also worth noting that Lake Kara was stocked with 550 brown trout which will further encourage northwest coast anglers to visit on opening weekend. Tight lines everyone, this season should be a ripper.
Due to unseasonal low lake levels at Bronte Lagoon, Bradys Lake, Lake Binney, Tungatinah Lagoon and Lake Echo, IFS has issued the following caution to anglers: Bronte Lagoon –The boat ramp at Bronte Lagoon Dam Wall is operational to -1.7 m below Full Supply Level (FSL). With the lagoon currently at -1.85 m extreme caution should be exercised when launching and retrieving boats. Bradys Lake – The new ramp at the Whitewater is operational to -3.9 m below FSL. The level is currently -3.9 m therefore caution should be exercised when launching and retrieving. Lake Binney – The boat ramp off the Lyell Highway is operational to approximately -3.0 m below FSL. The lake level is currently -3.9 m therefore launching and retrieving trailer boats is not recommended. Tungatinah Lagoon – The gravel ramp at Tungatinah Lagoon off the Lyell Highway is operational to approximately -3.0 m below FSL. The lake level is currently -3.9 m therefore launching and retrieving trailer boats is impossible at current levels. Lake Echo- The boat ramps at Large Bay, Middle Echo and the Dam Wall are all designed to operate to approx. -8.5 m below FSL. With the lake currently -9.15 m launching trailer boats is not recommended. As a general precaution boat operators should maintain extreme caution whilst navigating on all these waters due to submerged hazards just below the surface. A 5 knot speed limit is recommended. Forecast rain during this week may see some increase in lake levels. Check the current level anytime at: www.hydro.com.au
An inspection of the boat ramp at Lake Binney which coincided with a low lake level of -3.7 m allowed IFS staff to remove a large submerged tree from the toe of the ramp. The tree was lying across the bottom of the ramp just below the water level and could have been an unpleasant surprise for early season anglers.
As part of the MAST/Hydro Tasmania upgrade of the Whitewater boat ramp at Bradys Lake, Central Highlands Council have completed improvements to the turning circle and widened the access road to provide space for parallel parking on both sides. Central Highlands Council’s in-kind contribution to the project is valued at $10, 000. Completion of the parking area and turning circle has put the finishing touches on a major project for anglers visiting the central highlands region. Many thanks to MAST, Hydro and Central Highlands Council for an excellent job.
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.
