New fishing rules for NSW – Dusky flathead and lobster

Following public consultation in November 2021, new rules for Dusky Flathead and Lobster will apply to NSW recreational fishers from August 1, 2022. These new rules can be found below.

Dusky Flathead

New legal length (slot limit): 36 cm to 70cm.
Daily bag limit: 5 fish.
Possession limit: A possession limit of 10 fish will remain in place to enable fishers to possess double their bag limit. This will allow for storage and freezing of fish for future consumption.

Why are these changes being implemented?

“Following community support from a comprehensive consultation process, the NSW Government is introducing new recreational fishing rules for Dusky Flathead. The rule changes are also supported by the Recreational Fishing NSW Advisory Council.

The community support for the rule changes received during the consultation process is consistent with community sentiment over the past decade for proactive, more conservative fishing rules, including a slot limit to provide for more protection of the spawning biomass in the stock.

Releasing large-sized Dusky Flathead has become socially important in recreational fisheries in NSW and elsewhere in Australia. This has certainly led to enhanced fishing opportunities with released fish being recaptured by fishers over time.

These changes will help boost the stock of bigger fish and ultimately provide better fishing opportunities for recreational fishers for this highly popular species in the future.”

What impact will these changes have on the Dusky Flathead stock in NSW?

“Introducing an upper legal limit of 70 cm will provide for greater protection of large reproductively important female fish. This will in turn result in an increase of the spawning biomass in the stock and subsequent increase in egg production. A slot limit and bag limit reduction would also promote a more natural age structure (comprising more ‘older’ fish) which may have important implications for stock resilience.”

What chance of survival do they have after release?

“Several scientific studies have considered post-release survival of recreationally caught Dusky Flathead and have shown the species to have high (~90%) survival following capture, handling, and release.  This suggests that the survival of additional fish caught and released as a result of the proposed changes will not result in significant additional mortality.

This is further been demonstrated through the significant community interest in DPI’s Trophy Flathead program in Lake Macquarie, St Georges Basin, and Tuross Lake, which encourages recreational fishers to voluntarily release all Dusky Flatheads over 70 cm, combined with a targeted tagging program.

Between November 2016 and July 2021, a total of 838 Dusky Flathead over 70 cm have been tagged and released in these three recreational fishing havens. A total of 119 recaptures have been reported to DPI since the tagging program commenced. The high recapture rate (14.2 %) demonstrates not only the popularity of the species but also the resilience of this species to catch and release using hook and line recreational fishing methods.”

Does the slot limit for Dusky Flathead impact commercial fishing?

“No, the new slot size limit does not apply to commercial fishing activity to avoid any wasteful discard of large flathead. Scientific monitoring has shown that Dusky Flatheads greater than 70cm comprise typically fewer than 1% of commercial catches in any given year. Size composition of Dusky Flathead for commercial fishing is also highly constrained and managed through gear selectivity.”

Lobster

Daily bag limit: 3 lobsters, comprised wholly of any single species or a combination of species of Eastern Rock Lobsters (Sagmariasus verreauxi) or Southern Rock Lobster (Jasus edwardsii).

Why are these changes being implemented?

“As a result of effective management controls since the 1990s, the population of Eastern Rock Lobster has recovered to healthy stock biomass, resulting in the Total Allowable Commercial Catch (TACC) being progressively increased over time to the current level of 180 t in 2021/22. This has provided the basis for a bag limit increase for recreational fishers.

Following community support from a comprehensive consultation process and finalisation of the Lobster Harvest Strategy, the NSW Government has increased the Lobster bag and possession limit for recreational fishers. This rule change is also supported by the Recreational Fishing NSW Advisory Council.”

What is the current stock status of Eastern Rock Lobster?

“Eastern Rock Lobster is currently classified as sustainable in NSW. The latest Status of Australian Fish Stocks Reports can be viewed at www.fish.gov.au.

Ongoing stock assessment modelling by DPI scientists has shown an approximately threefold increase in biomass of Rock Lobster within the legal size range (104 mm -180 mm) since the mid-1990s when the stock was in a depleted state. As a result of effective management controls and the implementation of ongoing monitoring programs, the population of Eastern Rock Lobster has recovered to a healthy stock biomass.”

30 Second Fieldcraft: The Hunter’s OODA Loop

The OODA Loop was developed as a decision-making framework for aerial combat, designed to produce faster, more accurate responses under pressure. By consciously cycling through this simple 4-step process, pilots were able to outthink and outmanoeuvre their opponents in real time.

Today, the same principle is used everywhere from military strategy to business leadership, but it’s just as relevant in the field. For hunters, the ability to rapidly interpret new information and act on it can be the difference between a successful stalk and a missed opportunity.

ADF RESERVES vs. CITIZENS’ MILITARY FORCE: What’s the difference?

In my last article, I discussed an alternative solution to national service (conscription). My proposal was to establish a volunteer organisation to support our conventional forces in the event of a foreign invasion. When discussing this concept with a Queensland Senator, I was asked about the differences between the Australian Defence Force (ADF) Reserves and my proposed organisation, which I refer to as the Citizens Military Force (CMF). This article outlines my response to that question.
