Book Description
Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Book Description
The conference was co-hosted by the governments of Australia and Canada in co-operation with FAO and the support of the National Oceanographic and Atmospheric Administration (NOAA), USA, and the Department of Fisheries, NSW. The purpose of the conference was to address the challenges and opportunities of fisheries monitoring that are common to many fisheries.

Book Description
The Meeting reviewed the status of information available relating to these fisheries and the events in their recent development. The perspectives that were discussed tried to include those of governments whose vessels were fishing on the high seas in the study area and those of the industry with commercial operations in the area.

Book Description
This report covers historical aspects of the regional development of orange roughy fisheries, biology, stock assessment, ecosystem interactions, and key management issues. In light of debate regarding the sustainability of orange roughy fisheries, as well as fisheries for other long-lived deepwater species, this review describes how, by making the right choices and employing the best science available, there are now some demonstrably sustainable orange roughy fisheries. However, there remain considerable challenges. These include improving understanding of deepwater benthic communities in general, their genetics and population distributions, their dispersal, and their ability to recover from fishery-related and other impacts. With regard to the direct management of the fisheries, the report emphasizes important opportunities and needs to improve ageing and acoustic biomass estimation, and to better understand the genetics and population structure of the stocks of orange roughy that are fished and managed.

Book Description
The world’s oceans cover about 70% of our planet. To safeguard the delicate ecological and environmental functions of the oceans and their remarkable biodiversity, networks of marine protected areas are being created. In some of these areas, human activity is restricted to non-exploitative activities and in others it is managed in a sustainable way. Australia is at the forefront of marine conservation, with one of the largest systems of marine protected areas in the world. Big, Bold and Blue: Lessons from Australia’s Marine Protected Areas captures Australia’s experience, sharing important lessons from the Great Barrier Reef and many other extraordinary marine protected areas. It presents real-world examples, leading academic research, perspectives on government policy, and information from indigenous sea country management, non-governmental organisations, and commercial and recreational fishing sectors. The lessons learnt during the rapid expansion of Australia’s marine protected areas, both positive and negative, will aid and advise other nations in their own marine conservation efforts.
