During 17-19 April 2018, we conducted an in-lake survey at Little Pine Lagoon to assess:

  1. the CPUE for brown trout,
  2. the population structure, and
  3. the condition of fish.

Over two nights, we set 104 box traps and captured 482 brown trout, with all areas of the lagoon surveyed. We weighed and measured 362 brown trout for fork length, with the remaining 120 brown trout counted only. The CPUE for brown trout was 4.64 fish per trap, indicative of a high abundance of fish.

Of the 482 brown trout captured, 50 per cent were female, 36 per cent male, and the remainder immature fish. Table 7 shows the summary statistics for these fish. The average weight for all fish, including immature fish, was 917 grams. The average weight for fish over 300 mm was 1 044 grams, with 85 per cent of the fish measured being greater than 300 mm length (see Figure 8).

The growth of fish was good, with all fish displaying a healthy weight for a given length. Just over ten per cent of fish grew to over 500 mm (see Figure 8), with no signs of larger fish being in poor condition.

Discussion

There was good evidence the recruitment of brown trout has been consistent across several years with all length classes present (see Figure 9). However, recruitment resulting from 2016 spawning was not well represented, despite favourable conditions during winter/spring.

There were still reasonable numbers of fish surveyed in the 220-320 mm size range. The overall condition of brown trout was good, with 92 per cent in the fair to excellent range. There was no evidence of excessive harvest, with significant latent fishing effort apparent over the last six years.

In summary, Little Pine Lagoon has a high abundance of brown trout across a wide range of sizes. The vast majority of fish are in good condition and the growth of fish, relative to most other waters, is good. The annual harvest relative to fish abundance is sustainable and present fishery management actions are supporting the fishery.

During 23-25 July 2018, we undertook a trapping survey within the Pet Reservoir.
The purpose of the survey was to gain information on:

 catch per unit effort,
 the length structure of the brown trout population,
 the condition of fish, and
 an estimate of the brown trout population size.

Anglers Access - River Access

IFS has started assessing sites for extensions of the Anglers Access Program in the North, North West and River Derwent. As part of the Tyenna River willow control program a replanting day was held at Lanoma Estate on 6 June. Native trees were planted to stabilize banks before willow removal.

IFS and the Derwent Catchment Project are planning further field days on the Tyenna River as part of the willow control program. A revegetation day will be held in October and willow control days over the summer months. We will notify anglers of event dates. Volunteers are encouraged to participate.

News from IFS

We have received information that the gate into the Nineteen Lagoons has now been opened. With the settled, overcast weather forecast for the next few days and coming weekend it should be a good place to find a wild brown trout. This opens up easy access to Double Lagoon, Lake Ada, Lake Kay and the greater Western Lakes area.

For more information on the read check out our Angler Access brochure on the area.

ifs management planTasmanian Inland Recreational Fishery Management Plan 2018-28

In June, Sarah Courtney, Minister for Primary Industries and Water, launched the Tasmanian Inland Recreational Fishery Management Plan 2018-28.
The Plan will guide the management of the recreational trout fishery in Tasmania for the next 10 years. It aims to provide a sustainable, vibrant and healthy fishery.
After extensive public consultation, the Plan provides better opportunities for anglers, assesses fishery performance and conserves fish stocks as a recreational resource for future generations.

The plan outlines measures to increase participation locally and from tourism markets. It balances the needs for individual fishery management while standardising regulations.
It supports the actions to grow and develop recreational fishing in Tasmania. These include a freeze on trout fishing licences, improved access for anglers and better facilities that encourage female participation and angling tourism.

Our inland fisheries are amongst the best trout fisheries available in the world.

Over the first couple of weeks of this season, we have become aware that some anglers are not following size and bag limits. Of particular concern is

  1. taking undersized fish
  2. exceeding bag limit, and
  3. exceeding the number of fish permitted over 500 mm.

The Inland Fishing Code, supplied each year with your licence, is a great pocket reference to keep in your tackle box. The regulations are readily available on our website, the InFish App and on signage at major angling waters around the state.

North Coast squid closure

The north coast spawning closure for calamari and squid comes into effect from next Monday 1st October until 31st October for waters from Cape Grim east to Cape Naturaliste.

Commercially purchased squid bait can be used but you cannot possess a squid jig attached to a fishing line in the closed area.

Temporary signage has been placed at fishing spots and boat ramps. Read more about the closure.

Check closure dates

Over the weekend of 4 and 5 August, the 2018-19 angling season took off with a bang! Thousands of anglers around the state tried their luck with some fantastic fish caught. Our Officers were out with five teams patrolling 46 waters right across the state. We inspected 699 angling licences, 546 brown trout and 195 rainbow trout.

Please find attached here the 2018 Tasmanian Carp Management Program Annual Report.

Recreational rock lobster season opening dates are now confirmed:

All waters outside the East Coast Stock Rebuilding Zone (ECSRZ) - open from Saturday, 3 November 2018
East Coast Stock Rebuilding Zone - open from Saturday, 8 December 2018
The need to rebuild stocks of rock lobster on the East Coast has led to the decision to delay the opening date for the recreational season in the ECSRZ. Other areas in the Eastern Region will now open at the same time as the Western Region.

There are no changes to recreational catch limits.

The commercial rock lobster season has also been delayed, opening on 15 November in all waters outside the ECSRZ and on 11 December in the ECSRZ.
