- Bioengineering promotes an understanding of the interrelationship between fisheries scientists and engineers. It encourages the exchange of bioengineering information, criteria, and techniques among fisheries scientsits, fish culturists, and engineers.
- Canadian Aquatic Resources promtes the conservation, development, and wise management of aquatic resources in Canada, witin the context of sound ecological principles and sustainability. It gathers and disseminates information pertainign to Canadian fisheries and aquatic resources, and promotes the educational and technical aspects of the fisheries profession in Canada.
- Fisheries Information and Technology (formerly Computer User) provides fisheries scientists interested in the used of computers to support fisheries scientists interested in the used of computers to support fisheries management, research, education, and administration with an opportunity to exchange data, techniques, and public domain software. The Section publishes a newsletter and has an extensive library of fisheries software.
- Early Life History is devoted to interests in the egg, larvae, and juvenile stages of freshwater, estuarine, and marine fishes. It encourages and facilitates exchange of knowledge through a highly regarded newsletter, a detailed membership directory, annual Larval Fish Conferences and their published proceedings, related sessions at annual AFS meetings, and special symposia and workshops.
- Education (and Student Subsection) strives to improve the quality of education for fisheries scientists, promotes the exchange of information, techniques, and materials for progressive teaching, develops programs in continuing education, establishes curriculum guidelines for fisheries programs at colleges and universities, promotes public education and awareness, and assists AFS on matters requiring educational expertise. Other Section activities include adminisitration of the Award of Excellence in Fisheries Education, travel awards for students to attend the annual meeting, and the production of fisheries textbooks.
- Equal Opportunity works to encourage the exchange of information pertinent to the promotion of employment, education, scholarships, participation, professionalism, and recruitment for all individuals in the fisheries profession. The Section administers the J. Frances Allen Scholarship program and publishes a newsletter.
- Estuaries provides a Society-wide forum for discussing and resolving the major multidisciplinary, multiorganizational issues concerning estuaries. It assumes a liaison function with other professional societies invovled with estuarine issues and provides a forum for discussion and presentation of major estuarine issues to the membership through symposia and sessions at national meetings.
- Fish Culture develops criteria aimed at establishing levels of expertise among fish culturists, maintains a registry of member fish culturists, continuously upgrades the science of fish culture by organizing news items and information on meetings and job opportunities.
- Fish Health publishes a quarterly newsletter, the Section-established Journal of Aquatic Animal Health, and the "Fish Health Blue Book," combined with annual meetings, facilitates better communication between professionals concerned with diseases of fish, and offers a comprehensive certification program for fish pathologists and fish health inspectors.
- Fisheries Administration consists of administrators from federal, state, and provincial fishery resource management agencies -- the people who are responsible foor North America's fishery resources. Objectives of the Section are to improve the techniques, effectiveness, and efficiency of the administrative functions of fisheries resource management. The intent is to dispense with rigid formality, to communicate rather than just talk, and to learn more about the business of being an administrator.
- Fisheries Management works to develop new management concepts and techniques as well as programs in education and communication to solve fisheries management problems. The Section sponsors workshops, symposia, meetings, and special sessions on such topics as the role of fish culture and fisheries management, urban fishing, trout stream habitat improvement, fisheries computer applications, and fish-marketing techniques. The Section is also involved in continuing education short courses.
- Genetics'overall goal is to promote the conservation of genetic resources of natural fish populations. It brings together research biologists, resource managers, and agency administrators who are interested in genetic issues and who wish to work together to provide solutions for the fishery management community. The Section organizes and sponsors symposia and workshop at regional and national levels, and publishes a newsletter to communicate new techniques, progress reports, and news items.
- International Fisheries supports and promotes worldwide fisheries education, communication, and research efforts. It works to increase North American fisheries scientists' awareness of the interests, needs, and contributions of their colleagues worldwide, and assists in the international exchange of information and technical advice among fisheries workers of all nations. The Section participates in World Fisheries Congresses, publishes an international directory of fisheries-related organizations, sponsors symposia at the annual AFS meetings, and publishes a quarterly newsletter.
- Introduced Fish brings together members interested and involved in the use and management of aquatic organisms moved from one place to another as a result of human activities. It provides a forum for identifying and bringing attention to bear on the beneficial as well as the potentially harmful effects of introduced species. The Section encourages objective communication among scientists, administrators, managers, educators, aquaculturists, and others interested in the issues.
- Marine Fisheries aims to ensure that marine issues and techniques are adequately aired through sponsoring one or more symposia at the annual AFS meeting. The Section is especially intersted in maintaining a prominent profile for marine issues while encouraging dialogue with those that are predominantly freshwater scientists. The Section works to ensure that marine and freshwater scientists recognize their common interests so that salinity, a relatively important factor, does not create an unnecessary and weakening schism.
- Physiology promotes excellence in the science of fish physiology through improved communication between researchers and other professionals who need the most up-to-date information on physiological processes, tools, and techniques. The Section publishes a newsletter, and conducts symposia and workshops to disseminate the results of basic and applied research on fish physiology.
- Socioeconomics provides a professional forum for identifying and bringing attention to economic and social science education in fisheries; for encouraging communication among fisheries scientists, administrators, and others interested in economics and social sciences; and for supporting publication of papers dealing with economics and social sciences as applied to fisheries. The Section organizes symposia for national and regional AFS meetings and encourages publication of social science research in AFS journals.
- Water Quality is concerned with protection of aquatic habitat and the advancement of water pollution control. The Section encourages the development of improved professional and technical standards in the investigation, abatement, and regulation of water pollution problems. It conducts workshops and symposia and produces a timely and lively newsletter.
