Fisheries Occasional Publication No.21 - Allocation Of The Western Rock Lobster Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to IFAAC, the Department will outline what it believes are the most practical and cost effective ways of managing a system of allocation amongst the commercial, customary and recreational sectors. This recommendation recognises that cost efficiencies and outcomes will be greatly affected by the type of allocation model that is chosen. Consequently the Department recommends that the allocation system should be based on a single allocation to each sector that is available over the entire fishery.

The Department does not recommend having any finer scale zoning of the allocations, or the creation of exclusive recreational fishing areas. …

2002 Licensed Angler Survey: Summarized Results, Keith L. Hurley, Kristin L. Duppong-Hurley

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

On October 22, 2002, 5000 six-page surveys (Appendix 3) were sent to a stratified-random sample of Nebraska anglers drawn from the 2001 licensed anglers database. The database included all anglers who purchased a fishing license in 2001 as well as all lifetime fishing permit holders who purchased their license before or during 2001. The database did not include those possessing a free permit, such as veteran’s or senior citizen permits. The survey subsample (2.6% of the 2001-licensed angler database) was stratified such that the proportions of surveys in the subsample (4366 residents and 634 non-residents) matched the proportions of resident/non-resident …

Fisheries Occasional Paper No. 19 - Management Of Western Rock Lobster Fishery - Proposed Resource Sustainability Management Package For The Northern Zones (A And B), Department Of Fisheries Western Australia

Fisheries Occasional Publications

The proposed effort reduction management package presented in this paper was developed in close co-operation with rock lobster industry to address the short-term sustainability concerns regarding the level of breeding stock in the northern region.

The management package does not address the serious long-term sustainability or socio-economic issues (e.g. cost pressures and related fleet capacity) facing the industry. If the fishery stays with input controls there will need to be regular reviews of the level of exploitation and its impact on the breeding stock. If exploitation increases and the breeding stock continues to decline additional fishing effort reductions in the …

Fisheries Occasional Paper No. 20 - Management Of Western Rock Lobster Fishery - Advice To Stakeholders - Assessment Of Southern Zone Resource Sustainability Options, Department Of Fisheries, Western Australia

Fisheries Occasional Publications

The management options presented in this paper have been developed in close cooperation with the rock lobster industry to address the short-term sustainability and economic concerns regarding the level of exploitation and its impact on the breeding stock in the southern region. The main focus in the short-term is to consider options that reduce fishing effort during periods that may be economically inefficient to fish and at the same time reduce the level of exploitation.

The management package does not address the serious long-term sustainability or socioeconomic issues (e.g. cost pressures and related fleet capacity) facing the industry. If the …

Fisheries Research Report No. 149 - The Western Rock Lobster Fishery 2001/2002 To 2002/2003, C F. Chubb, E H. Barker

Fisheries Research Reports

Season 2001/2002 produced 8,983 tonnes, a far cry from last season’s catch of 11,300 t. The sharp decline in catch was most likely the result of unfavourable environmental conditions throughout much of the season. The catches by the three zones were 1,651 tonnes in zone A, 2,800 tonnes in zone B and 4,532 tonnes in zone C. The sharp decline in total catch on the previous season was also reflected in declining catches in the three zones. Nominal effort also declined slightly from 10.487 million pot lifts in 2000/2001 to 10.367 million pot lifts in 2001/2002. Following the very low …

Nebraska Catfish Anglers: Descriptions And Insights Derived From The 2002 Nebraska Licensed Angler Survey, Keith Hurley, Kristin Duppong-Hurley

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Analyses in this report will refer to number of different groups. Catfish seeking anglers are defined as any angler who has spend at least 1 trip during 2002 in pursuit of a catfish species (channel, blue, flathead, or bullhead). This is the most general group included in the analyses and is also the least avid group of anglers in regards to their relationship to catfish angling. Catfish anglers are defined as those respondents who identified a catfish species as the species they most prefer to target. Catfish anglers represent a smaller group of respondents with a higher avidity for catfish …

Key Grazing Levels (Foo Targets) For Pasture And Sheep Management, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Food On Offer (FOO) is the amount of pasture in front of an animal, and is measured in kilograms Dry Matter per hectare. Managing pastures to key grazing levels - or FOO targets - can result in improved production of grazing systems in Mediterranean environments which are characterized by slow winter growth, peak spring growth and dry summers. These targets vary according to what production response is required.

This information sheet illustrates key target FOO for sheep grazing annual pastures during autumn and spring.

Fisheries Research Contract Report No. 10 - Mother-Of-Pearl Shell (Pinctada Maxima): Stock Evaluation For Management And Future Harvesting In Western Australia, Anthony M. Hart, Kim J. Friedman

Fisheries Research Contract Reports

The West Australian Pearling industry is one of Australia's most valuable aquaculture industries, currently generating around $120 - $160 million annually. The majority of pearl shell used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller (120mm - 165mm DVM) shell (hereafter defined as 'culture' shell), that are more suitable for culturing of pearls, leaving larger MOP oysters (175mm+) on the pearling grounds. These larger pearl oysters, the majority of which are female (protandric hermaphrodites), form a major component of the broodstock for the

fishery. Although MOP …

Fisheries Research Contract Report No. 8 - The Nutritional Management Of Barramundi, Brett Glencross

Fisheries Research Contract Reports

Barramundi nutrition research has been undertaken since 1988. Since that time the requirements for most nutrients, energy demand, ingredient utilisation and the effects of nutrition on flesh quality aspects have all been examined to varying extents.

Optimal protein content of diets has been shown to vary with diet energy density and also the size of fish which are being fed. Most studies have suggested a protein requirement from 45% to 55%. For small fish a protein to energy ratio of 25 to 30 g/MJ is suggested. Limited work has been done on fish larger than 500 g. The 10 essential …

Proposals For Community Discussion : A Quality Future For Recreational Fishing In The Pilbara/Kimberley : A Five-Year Draft Strategy For Managing The Recreational Component Of The Catch, Pilbara/Kimberley Recreational Fishing Working Group.

Fisheries Management Papers

With a growing population and advances in technology, fishing pressure will continue to grow and anglers will become more efficient at targeting fish - particularly offshore demersal species, such as tropical snappers and emperors. There is also a clear need for recreational fisheries management to complement the existing management arrangements for the charter industry, and provide the necessary framework for recreational fishing to be incorporated into an integrated management framework with other fishing sectors.

Fisheries Management Paper No.180 - Future Management Arrangements For Western Australia's Temperate Shark Fisheries., Jane Borg, R. Mcauley

Fisheries Management Papers

This paper provides a summary of the attributes of these temperate shark fisheries, and sets out the proposed objectives and the measures available to achieve them.

In summary, primary measures are aimed at the sustainability of dusky and whiskery sharks, with dusky sharks being of greater concern as their status is more critical. The final decision on management of these fisheries cannot compromise sustainability, not only because of the Department’s obligations under the Fish Resources Management Act, 1994, but also:

• national and international obligations associated with ecologically sustainable development;

• export accreditation under the Environmental Protection and Biodiversity Conservation …

Fisheries Occasional Publication No. 6 - Anglers Guide To Assessing Reproductive Stage In Fish, Kim Smith, Mike Mackie, Department Of Fisheries Western Australia

What is a gonad?

"Gonad" is a general term for a reproductive organ, and is used to describe both ovaries and testes. In male and female fish, the gonad is an elongated organ lying along the upper wall of the gut cavity (i.e. running immediately under the vertebral column). The gonad gonad has 2 lobes. Both lobes are attached to the body near the anus and extend forward inside the gut cavity.

As fish gonads ripen, they become larger, heavier and change colour. Immature and undeveloped adult gonads are very small, strap-like in shape, pinkish in colour and translucent (i.e. …

This project has drawn together existing research data relating to natural and human impacts on the Abrolhos Islands marine habitats. It has surveyed current uses of these habitats and placed anthropogenic impacts within the context of natural perturbations. Through public forum presentation and debate, this work has allowed real issues, not perceptions, to surface and be addressed properly. This was achieved by defining a strategic programme of research through a scientific workshop process involving all community stakeholders. A two volume Fisheries Research Report (WA) summarizes current knowledge and details the workshop proceedings and strategic research plan.

Terrestrial Natural Communities Of Nebraska (Version Iii - June 30, 2005), Gerry Steinauer, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

For more than a decade, The Nature Conservancy (TNC) and state natural heritage programs, including the Nebraska Natural Heritage Program (NNHP), have used a “coarse filter/fine filter” approach to preserving biological diversity (The Nature Conservancy, 1994). This approach involves identification and protection of natural communities (coarse filter) as well as rare species (fine filter). Identifying and protecting representative examples of natural communities ensures conservation of most species, biotic interactions and ecological processes. Those species that “fall through” the community filters are generally the rare species. Identification and protection of viable occurrences of rare species serves as the fine filter for …
