Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia. Jul 2013

Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia.

Fisheries management papers

The practice of releasing hatchery-reared fish into existing populations to augment fishing (stock enhancement) or restore depleted spawning biomass (restocking) has occurred around the world for decades with varying degrees of success. The underpinning concept is to produce and release fish into wild populations to increase their abundance, catch rates and/or fishery yields

If restocking and stock enhancement activities are to be successful, they should have clear objectives and be well planned and targeted at situations where there is a reasonable expectation of having a beneficial effect.

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia Oct 2012

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia

Fisheries management papers

The Department of Fisheries (Department) is proposing a new simplified management approach which focuses on fishing as the core criteria in the new licensing framework. Given the low level of impact of aquatic eco-tours and shore-based fishing, consideration is being given to removing the need for these activities to be formally licensed. The Department is of the view that these activities can be adequately managed by regulations that have broader application across the community.

The current management, licensing and fee structures are complex and provide limited business flexibility. A simplified management approach will also improve the Department’s capacity to monitor …

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel Jan 2005

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel

Fisheries management papers

The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg Aug 2002

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries management papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …
