Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place. Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies and the oceans. About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations.
A conventional idea of a sustainable fishery is that it is one that is harvested at a sustainable rate, where the fish population does not decline over time because of fishing practices. Sustainability in fisheries combines theoretical disciplines, such as the population dynamics of fisheries, with practical strategies, such as avoiding overfishing through techniques such as individual fishing quotas, curtailing destructive and illegal fishing practices by lobbying for appropriate law and policy, setting up protected areas, restoring collapsed fisheries, incorporating all externalities involved in harvesting marine ecosystems into fishery economics, educating stakeholders and the wider public, and developing independent certification programs.
Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic and industrial biology, morphology, and physiology. The one distinguishing aspect is that all fields relate to aquatic organisms. Most work is related to limnology and can be divided into lotic system ecology and lentic system ecology.
Unsustainable fishing methods refers to the utilization of the various fishing methods in order to capture or harvest fish at a rate which sees the declining of fish populations over time. These methods are observed to facilitate the destructive fishing practices that destroy ecosystems within the ocean, and is used as a tool for over-fishing which results in the depletion of fish populations at a rate that cannot be sustained.
CSIRO Publishing is an Australian-based science and technology publisher. It publishes books, journals and magazines across a range of scientific disciplines, including agriculture, chemistry, plant and animal sciences, natural history and environmental management. It also produces interactive learning modules for primary school students and provides writing workshops for researchers.
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs. According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. There is a growing gap between the supply of fish and demand, due in part to world population growth.
The Australian Continuous Plankton Recorder (AusCPR) survey is a joint project of the CSIRO and the Australian Antarctic Division, DEWHA, to monitor plankton communities as a guide to the health of Australia's oceans.
Carl Walters is an American-born Canadian biologist known for his work involving fisheries stock assessments, the adaptive management concept, and ecosystem modeling. Walters has been a professor of Zoology and Fisheries at the University of British Columbia since 1969. He is one of the main developers of the ecological modelling software Ecopath. His most recent work focuses on how to adjust human behaviors in environments that are full of uncertainty. He is a recent recipient of the Volvo Environment Prize (2006). In 2019, Dr. Walters became a Member of the Order of British Columbia.
The Future of Marine Animal Populations (FMAP) project was one of the core projects of the international Census of Marine Life (2000–2010). FMAP's mission was to describe and synthesize globally changing patterns of species abundance, distribution, and diversity, and to model the effects of fishing, climate change and other key variables on those patterns. This work was done across ocean realms and with an emphasis on understanding past changes and predicting future scenarios.
Boris Worm is a marine ecologist, and the Killam Research Professor at Dalhousie University in Halifax, Nova Scotia, Canada.
The Institute for Marine and Antarctic Studies (IMAS) is a teaching and research institute of the University of Tasmania in Hobart, Tasmania. IMAS was established in 2010, building upon the university's partnership with CSIRO Oceans and Atmosphere and the Australian Antarctic Division in cooperative Antarctic research and Southern Ocean research.
Raymond (Ray) John Heaphy Beverton, CBE, FRS was an important founder of fisheries science. He is best known for the book On the Dynamics of Exploited Fish Populations (1957) which he wrote with Sidney Holt. The book is a cornerstone of modern fisheries science and remains much used today. Beverton's life and achievements are described in detail in several obituaries written by prominent figures in fisheries science.
The Australian Society for Fish Biology (ASFB) is a professional organisation of fish and fisheries researchers. Founded in 1971, the society describes itself as a "professional, independent, non-profit, non-commercial and non-aligned organisation." The Australian Society for Fish Biology holds annual conferences for its members, sometimes in partnership with related organisations such as the Oceania Chondrichthyan Society and the Australian Society for Limnology. Former presidents of the society include Hamar Midgley (1977–79), Gerry Allen (1979–81), Julian Pepperell (1991–93) and Bronwyn Gillanders (2012–13).
CSIRO Oceans and Atmosphere (O&A) is one of the current 8 Business Units of the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia's largest government-supported science research agency.
Jessica Melbourne-Thomas is a marine, Antarctic and climate change scientist with the Commonwealth Scientific and Industrial Research Organisation, Australia. Her research focuses on climate change, its effects on the marine environment, and how to adapt and response to these changes.
Gretta T. Pecl is an Australian marine ecologist, Australian Research Council Future Fellow, and the Director of the Centre for Marine Socioecology (CMS) at the University of Tasmania. Her work focuses on species and ecosystem responses to climate change, as well as using socioecological approaches to adapt natural resource management for climate change. She is on the editorial board of Springer Nature's Reviews in Fish Biology and Fisheries, and is a Subject Editor for Ecography.
The K. Radway Allen Award is the highest honour awarded by the Australian Society for Fish Biology. It recognises individuals who have made an "outstanding contribution in fish or fisheries science." The award, inaugurated in 1995, is named for New Zealand fisheries biologist Kenneth Radway Allen.
Peter Colin Young is a British-born ichthyologist and parasitologist who spent most of his career in Australia. From 1995 to 1997, he served as President of the Australian Society for Fish Biology.
Marine Permaculture is a form of mariculture that reflects the principles of permaculture by recreating seaweed forest habitat and other ecosystems in nearshore and offshore ocean environments. Doing so enables a sustainable long-term harvest of seaweeds and seafood, while regenerating life in the ocean.
The Fisheries and Marine Ecosystem Model Intercomparison Project (Fish-MIP) is a marine biology project to compare computer models of the impact of climate change on sea life. Founded in 2013 as part of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP), it was established to answer questions about the future of marine biodiversity, seafood supply, fisheries, and marine ecosystem functioning in the context of various climate change scenarios. It combines diverse marine ecosystem models from both the global and regional scale through a standardized protocol for ensemble modelling in an attempt to correct for any bias in the individual models that make up the ensemble. Fish-MIP's goal is to use this ensemble modelling to project a more robust picture of the future state of fisheries and marine ecosystems under the impacts of climate change, and ultimately to help inform fishing policy.
