Fisheries and aquaculture produce highly nutritious foods that are generally of high value, and often targeted at export markets. Slow to recognise the threats from climate change, research by sectoral experts and greater attention to aquatic systems (freshwater and marine) by the IPCC rapidly improved understanding of likely productivity changes f...

Compared with other aquaculture issues, attention to human and social dimensions is lagging behind. Sectoral development, policy, and programmatic factors have created inequities and sub‐optimal social outcomes, which are jeopardizing the broader contribution the sector could make to human well‐being. Human rights in aquaculture are at the core of...

A common goal among fisheries science professionals, stakeholders, and rights holders is to ensure the persistence and resilience of vibrant fish populations and sustainable, equitable fisheries in diverse aquatic ecosystems, from small headwater streams to offshore pelagic waters. Achieving this goal requires a complex intersection of science and...

In fisheries and aquaculture, technology is a critical factor in sectoral development. Tracing the sectors’ post World War II development stages, we note strong links with internal and external economic and sustainability drivers but weak connections to largely external gender equality and human rights drivers. Three characteristics of the fish sec...

Gender equality, a universal agreed principle and value, has been adopted widely but implemented to varying levels in different sectors. Our study was designed to contrast how gender development (here-after 'development') and fisheries sectors view and invest in gender, and then explore opportunities to strengthen collaborative relationships and ne...

The USD6 billion Western and Central Pacific Ocean (WCPO) tuna fisheries produce over half the world's tuna and are important for coastal countries. Tuna fisheries policy, management and research currently focus on fisheries resources and industrial fishing on offshore vessels with all male crews, although women, as much as men, are employed in tun...

While there is much debate on transformative change among academics and policymakers, the discussion on how to govern such change is still in its infancy. This article argues that transformative governance is needed to enable the transformative change necessary for achieving global sustainability goals. Based on a literature review, the article unp...

Since 1990, papers presented at successive women/gender and fisheries conferences of the Asian Fisheries Society have followed a pathway trodden by other fields of gender research. Starting with noticing androcentrism in fisheries, the conferences proceeded to noticing the omissions and adding depth of detail on women’s roles and their contribution...

The 7th Global Conference on Gender in Aquaculture and Fisheries (GAF7), held from 18-21 October 2018 at the Asian Institute of Technology, Bangkok, was organised by the Gender in Aquaculture and Fisheries Section (GAFS) of the Asian Fisheries Society (AFS), the Asian Institute of Technology and the Network of Aquaculture Centres in Asia Pacific.

In the 1970s, only 3 million tonnes of aquatic animals and plants were grown in aquaculture; today, the total production exceeds 100 million tonnes and strong growth continues. Women work in all sections of the aquaculture value chain but their opportunities have not kept pace with its growth. Indeed, many opportunities have contracted under the pr...

A biologist whose career spans several decades will most likely find the scientific name of the species on which she or he first worked has been changed. With the use of modern information technology, and better species identification and description tools including genetics, marine fish taxonomy has greatly improved the rate of success in naming v...

China’s 13th Five-Year Plan, launched in March 2016, provides a sound policy platform for the protection of marine ecosystems and the restoration of capture fisheries within China’s exclusive economic zone. What distinguishes China among many other countries striving for marine fisheries reform is its size—accounting for almost one-fifth of global...

In this Guest Editorial, we reflect on the “long journey” to addressing gender equality in aquaculture and fisheries, the emerging trends that we saw in GAF5, and the trends more generally in gender in the fisheries and aquaculture sectors. We also provide an overview of the papers in this Special Issue.

Dedicated fisheries and aquaculture institutions such as departments of state and of universities, and specialist research institutions play critical roles in key sectoral matters such as fisheries management and fish health. They pay little attention, however, to seemingly less urgent issues such as gender equality and equity. The present paper ex...

From a fisheries perspective, the time has come to reframe the issue of illegal cross-border fishing in Southeast Asia, and enlarge the range of solutions beyond state-based maritime security. States could re-position their fisheries strategy by helping inform themselves and educate the public on sustainability, and put greater focus on bringing fi...

Fish provides more than 4.5 billion people with at least 15 % of their average per capita intake of animal protein. Fish's unique nutritional properties make it also essential to the health of billions of consumers in both developed and developing countries. Fish is one of the most efficient converters of feed into high quality food and its carbon...

Download URL <http://www.stapgef.org/sites/default/files/stap/wp-content/uploads/2013/05/Hypoxia-and-Nutrient-Reduction.pdf> Rapid economic development and population growth, much of it along the world’s coasts, plus increasing agriculture and livestock production, have placed huge environmental pressures on coastal ecosystems from direct resource...

The Census of Marine Life aids practical work of the Convention on Biological Diversity, discovers and tracks ocean biodiversity, and supports marine environmental planning.

The production of food from marine and freshwaters is undergoing a profound revolution—from hunting to farming or from fishing to aquaculture. Fishing and aquaculture exploit and alter the biodiversity on which they are based, each in different but convergent ways. Fishing harvests a much larger range of biodiversity at ecosystem, species and genet...

People are at the heart of sustaining aquaculture. Development of human capacity and gender, therefore, is an important human dimension. Human capacity development (HCD) was a major thrust of the 2000 Bangkok Declaration and Strategy, but gender was not addressed. The Food and Agriculture Organization of the United Nation's (FAO) Strategic Framewor...

Marine capture fisheries face major and complex challenges: habitat degradation, poor economic returns, social hardships from depleted stocks, illegal fishing, and climate change, among others. The key factors that prevent the transition to sustainable fisheries are information failures, transition costs, use and non-use conflicts and capacity cons...

Based on a case study carried out within fishing communities in Mali, Charlotte Tindall and Katrien Holvoet describe the implications of gender relations in the fisheries chain. They argue that addressing power and gender inequities throughout the marketing chain improves men&apos;s and women&apos;s livelihoods and the sustainability of the resourc...

When tropical cyclone Larry crossed the Queensland coast on 20 March 2006, commercial, recreational and naval vessels in the port of Cairns, 60 km north of the eye of the cyclone and others closer to the eye, were protected from the destructive winds by sheltering in deep mangrove creeks in Trinity Inlet and off other coastal rivers. The Trinity In...

Yellowfin bream, Acanthopagrus australis, support an important angling fishery in Moreton Bay, a large estuarine system on the east coast of Australia. An analysis of the records of catches by anglers indicates that abundance and mean size of yellowfin bream have changed little in Moreton Bay during the period 1945 to 1980. Over the past 5 years su...

All over the world, women contribute in multiple ways to the production, processing, marketing and management of fish and other living aquatic resources. The first ever Global Symposium on Women in Fisheries, held in Kaohsiung, Taiwan on 29 November 2001 generated the present collection of papers on women in fisheries. The reader of this volume wil...

In Africa, aquaculture has developed only recently and so far has made only a small contribution to economic development and food security. We review developments and identify constraints to the expansion of aquaculture in economic and rural development at the continental, national and farm levels. Past development initiatives failed to achieve sus...

May I respond to the Policy Forum “Nature's subsidies to shrimp and salmon farming” by Rosamond L. Naylor et al. (30 Oct. Science 's Compass, p. [883][1])? Like many new endeavors, this industry is undergoing rapid change, but the authors focus only on its present performance in forming their

Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ecological consequences on ocean resources through habitat destruction, effluent discharge, exotic species introductions, and...

Some definitions of ‘Development’ are reviewed, with emphasis on natural resources and environmental issues. Earlier theories of development, based on industrialization and building of physical infrastructures, with the state and the industrial sectors as key actors, are now being replaced by a focus on education, and empowerment of new actors, not...

The fishing industry's aggressive and expanding search for fish from the sea reached a turning point in 1990. After many years of increasing production, the global marine and inland catch from natural stocks declined from the 1989 peak of about 89 million tons to 85 million tons in 1993. Aquaculture production did not increase enough to meet the sh...

Global changes in living aquatic resources could threaten progress towards sustainable food security in many parts of the developing world, but they could also stimulate improved use of living aquatic resources. Some of the outcomes depend upon actions taken today. Human impacts have already transformed the Earth’s terrestrial environment and may w...

"Global-scale changes in the supply, demand, value, management and uses of fisheries resources could threaten progress towards sustainable food security in many parts of the developing world, but they could also stimulate improved management and use of the resources. Decisionmakers are searching for better ways of managing all fisheries, including...

Through its basic marine research over the past twenty years, the Australian Institute of Marine Science (AIMS) has become a recognised marine science research authority, particularly in relation to corals and mangroves. Over the past five years, it has been working at a moderate level of applied research with industry and is intent on building on...

The incidence of non-melanoma skin cancer, comprising basal cell carcinoma and squamous cell carcinoma, was studied in Queensland during 1984. The world-standardised annual incidence rates (per 100,000 population) for the number of persons with non-melanoma skin cancer were estimated to be 1372 for men and 702 for women, the highest recorded incide...

This paper reviews the current status of selected major fisher-ies stocks in the Australian Fishing Zone. The author argues that regardless of limited potential increases in catch, the Australian fishing industry can still look forward to a more prosperous future through making better use of available catch.

Laboratory and field trials of a modified Floy FD67 anchor tag were conducted on P. pelagicus in Moreton Bay, Queensland. The tags did not affect short-term survival of the crabs in the laboratory. Only 470 of 1754 crabs tagged and released in the field were returned. Return rates of crabs by size, sex, and area of tagging class were markedly heter...

Crab pots were used to sample a population of Scylla serrata (Forskal) in an estuarine area in Queensland, Australia. Pots were laid 100 m apart at fixed positions for 4 d each month for 1 yr (April 1980–June 1981). Data from recapture of tagged crabs showed that males larger than 140 mm carapace width and females larger than 150 mm had a higher ca...

Portunus pelagicus Linnaeus is a bottom-feeding carnivore, eating a wide variety of sessile and slow moving invertebrates. Diet is largely dependent upon local availability of prey species: the main foods for intertidal P. pelagicus are small hermit crabs and gastropods and for subtidal P. pelagicus are bivalves and ophiuroids. Diet composition cha...

In Deception Bay, northern Australia, during 1979–1981, a study was made of the distribution of Scylla serrata (Forskal) in an area having a broad intertidal zone. Juveniles (20 to 99 mm carapace width) were resident in the mangrove zone, remaining there during low tide. The majority of subadult crabs (100 to 149 mm) migrated into the intertidal zo...

Merits of the points and occurrence methods for measuring the relative importance of types of food eaten by four species of portunid crabs (Portunus pelagicus (Linnaeus, 1766), Thalamita crenata H. Milne Edwards 1834, T. danae Stimpson 1858, and T. sima H. Milne Edwards 1834) have been compared. Both methods describe different aspects of the relati...

Tag-recapture data were used to determine growth and movement of A. japonicum balloti. The von Bertalanffy growth model was found to be suitable for describing growth in the latter half of the size range for A. japonicum balloti, and estimated S∞ of scallops varied with year and area. A. japonicum balloti grows rapidly, being recruited to the comme...

Morphometric data for males of three species of Uca and females of two species have been summarized in terms of concepts of shape and allometry using the multivariate linear model. Differences among species are greatest in the males where U. vocans develops a major chela with broad palm, greatly elongated fingers and large gape, while U. lactea pro...

Food handling by the mud crab S. serrata is described. Each of the dimorphic chelae of S. serrata performs specific functions in the opening of shells of the mussel Trichomya hirsuta.

International Symposium on Women in Asian Fisheries presents a record of the 1998 symposium.
