A Bycatch Action Plan For The Pilbara Fish Trawl Interim Managed Fishery., Department Of Fisheries Western Australia

Fisheries Management Papers

The effect of commercial fishing on bycatch species and the marine ecosystem generally, has emerged as a significant national and international issue. Environmental issues associated with bycatch – including impacts on the ecology of non-target species of fish and wildlife – are important issues to address in reducing the impacts, or potential impacts, of commercial fisheries.

In 1998, the National Standing Committee on Fisheries and Aquaculture developed a national policy on fisheries bycatch. In 1999, the (then) State Minister for Fisheries adopted the national policy as his position on bycatch for Western Australia. The main objective of the policy is …

Effects Of Variable Oceanographic Conditions On Forage Fish Lipid Content And Fatty Acid Composition In The Northern California Current, Marisa N. C. Litz, Richard D. Brodeur, Robert L. Emmett, Selina S. Heppell, Rosalee S. Hellberg, Linda O'Higgins, Matthew S. Morris

Food Science Faculty Articles and Research

Lipids and fatty acids (FA) were investigated in 4 species of forage fish: northern anchovy Engraulis mordax, Pacific sardine Sardinops sagax, Pacific herring Clupea pallasi, and whitebait smelt Allosmerus elongatus, for their ability to serve as biological indicators of ocean conditions in the California Current large marine ecosystem (CCLME). Samples were collected during the oceanographically contrasting years of 2005 and 2006. Upwelling was severely curtailed in the spring and early summer of 2005, leading to delayed biological productivity, whereas upwelling was relatively normal in spring 2006. Principal components analysis described 78% of the variance within the …

Countermeasure Policy On The Samho Brother Benzene Ship Accident, Chin-Long Lin, Jian-Hwa Hu

Journal of Marine Science and Technology–Taiwan

On October 10th, 2005, the chemical ship SAMHO BROTHER mishap occurred in the Taiwan Strait while transporting a cargo of benzene. Explosive approach was applied but failed, causing the ship wreck sank to a depth of 70 m. Oil spill was recovered in a small amount, leaving about 50 tons of the fuel remained. On the other hand, environmental monitoring at the site of the accident revealed that almost all of the great amount of 3140 m3 benzene remains stored in the nine tanks on the ship and further actions upon such a unique event in the history are urgent. …

Biological Sciences Faculty Publications

Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. To address this gap, species-specific information on global distribution, population status, life history traits, and major threats were compiled for each of the …

Multi-Host Model-Based Identification Of Armillifer Agkistrodontis (Pentastomida), A New Zoonotic Parasite From China, Shao-Hong Chen, Qin Liu, Yong-Nian Zhang, Jia-Xu Chen, Hao Li, Ying Chen, Peter Steinmann, Xiao-Nong Zhou

Harold W. Manter Laboratory of Parasitology: Library Materials

Background: Pentastomiasis is a rare parasitic infection of humans. Pentastomids are dioecious obligate parasites requiring multiple hosts to complete their life cycle. Despite their worm-like appearance, they are commonly placed into a separate sub-class of the subphylum Crustacea, phylum Arthropoda. However, their systematic position is not uncontested and historically, they have been considered as a separate phylum.

Methodology/Principal Findings: An appraisal of Armillifer agkistrodontis was performed in terms of morphology and genetic identification after its lifecycle had been established in a multi-host model, that is, mice and rats as intermediate hosts, and snakes (Agkistrodon acutus and Python molurus) …

Shark Bay Prawn And Scallop Fisheries: Final Review Report, Western Australia. Department Of Fisheries

Fisheries Management Papers

The Shark Bay Prawn Fishery and Shark Bay Scallop Fishery operate in the same general areas of Shark Bay (although there are some differences in their areas of operation). The interrelationship between trawling activities for the two target species (prawns and scallops) has raised both management challenges and industry conflicts over time. Harvest level settings for each fishery (in the form of effort levels and the timing and/or location of fishing) are independently set, on the basis of recruitment and abundance surveys of each target species. However, each industry sector strongly believes that the interactions between the fisheries arise because …

Journal of Marine Science and Technology–Taiwan

The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating activity, superoxide anion radical scavenging activity and reducing power, and the immune-stimulating activity by using HB4C5 cells and J774.1 cells. It was found that the antioxidant activity was increasing in correlating with the concentration below 3.5 mg/ml. The HB4C5 cells showed the maximum relative activities of cell proliferation (174%) and IgM secretion (132%) at 120 µg/ml of hot-water extract. Overheating slightly reduced the immune-stimulating activity of hot-water extract. At 80 µg/ml, J774.1 cells showed the maximum …

The Efficacy Of Sanctuary Areas For The Management Of Fish Stocks And Biodiversity In Wa Waters, James W. Penn, Warrick J. Fletcher

Fisheries Research Reports

Debate concerning the relative benefits of marine protected areas (MPAs) for the management of marine resources can often reflect unrecognized differences in the scope, scale and definitions of the objectives being sought by various Government or community bodies. There can also be different opinions on the level of protection required for an area to be considered an ‘MPA’ and functional definitions for both the biological diversity and ecosystems within these areas are often lacking. This paper seeks to outline the relative efficiency and effectiveness of MPAs, especially no-take sanctuary areas, compared to other strategies currently employed to help achieve the …
