Abstract: Fish consumption advisories fail to adequately help communities address the benefits and risks of eating potentially contaminated fish. We engaged community members and relevant institutions in identifying and implementing more effective risk communication in Michigan's rural Upper Peninsula. In 2004-2005, we collected data in four Michigan counties through focus groups, community dinners, public meetings and angler interviews. Residents express a strong affinity toward eating Great Lakes fish, though a minority of participants have read the official fish advisory. Participants lack an understanding of how bioaccumulation affects consumption risk depending on the type of contaminant. We attribute the situation to conditions of post-normal risk that emerge through interaction of the structural dimensions of science and bureaucracy with a strong natural resource-based culture that affects the agency of residents. The implications loom large as Michigan's Department of Community Health no longer distributes hard copies of the Michigan Fish Advisory. (Contains 6 figures and 2 tables.)

2. Vertebrate Osmoregulation: A Student Laboratory Exercise Using Teleost Fish (EJ780849)
Boily P.; Rees, B. B.; Williamson, L. A. C.
Advances in Physiology Education, v31 n4 p352-357 Dec 2007
2007-12-00
Descriptors: Majors (Students); Animals; Physiology; Biology; Laboratory Experiments; Student Projects; Science Activities; Cytology; Cooperative Learning; Ichthyology; Laboratory Training; Course Descriptions
Abstract: Here, we describe a laboratory experiment as part of an upper-level vertebrate physiology course for biology majors to investigate the physiological response of vertebrates to osmoregulatory challenges. The experiment involves measuring plasma osmolality and Na[superscript +] -K[superscript +] -ATPase activity in gill tissue of teleost fish acclimated to water of differing salinity. We describe results obtained using the widely available goldfish ("Carassius auratus") and a common baitfish, the Gulf killifish ("Fundulus grandis"). The procedures described are generally applicable to other fish species, and they provide an alternative to the experimental use of humans or other mammalian species to investigate osmoregulation mechanisms. In addition to reenforcing the conceptual material covered in lecture, this laboratory exercise trains students in a wide range of laboratory and analytical skills, such as calculating and performing dilutions, pipetting, tissue sampling and homogenizing, preparing standard curves, conducting enzymatic assays, and analyzing and interpreting results. Typical student results are presented and discussed, as are common experimental and conceptual mistakes made by students. (Contains 5 figures. Appended to this document are descriptions of solutions needed for two laboratory sections of six groups of students.)

3. Educating and Training out of Poverty? Adult Provision and the Informal Sector in Fishing Communities, South Africa (EJ768366)
Petersen, Carolyn
International Journal of Educational Development, v27 n4 p446-457 Jul 2007
2007-07-00
Journal Articles; Reports - Evaluative
Descriptors: Foreign Countries; Adult Education; Rural Areas; Poverty; Animals; Ichthyology; Vocational Education; Depleted Resources; Economically Disadvantaged; Power Structure; Low Achievement; Social Status
Abstract: This paper looks at access to adult education and vocational education and training (VET) provision in fishing communities in the Western Cape, South Africa. Fishing communities are being disadvantaged due to geographical and socio-political marginalisation, and the predominance of informal sector employment in the context of worldwide marine resource depletion. Neither public nor private provision is adequately serving rural areas or the informal sector in this context. Using the sustainable livelihoods approach as a tool of analysis, this paper argues that a more cross-sectoral approach is needed to tackle equity and poverty concerns in adult education and training provision.

4. Game Time! (EJ758289)
Marek, Edmund; Howell, Beverly
Science and Children, v44 n3 p48-50 Nov 2006
2006-11-00
Journal Articles; Reports - Descriptive
Descriptors: Science Instruction; Science Curriculum; Educational Games; Grade 2; Grade 3; Grade 4; Teaching Methods; Animals; Scientific Concepts; Creative Teaching; Ichthyology; Elementary School Science
Abstract: In this article, the authors present a classic playground game called "Sharks and Fishes" to introduce second- to fourth-grade students to the concept of "predation," or the relationships between a predator and its prey. By incorporating the game in a learning cycle on predation, students not only learn about predation in a memorable way, but they also have a "teacher-sanctioned" opportunity to move around during class while collecting data. The authors discuss how the game can be played, explain the concept of predation, and describe other engaging activities that explore predator-prey relationships. (Contains 3 resources.)

5. A Strange Fish Indeed: The "Discovery" of a Living Fossil (EJ725455)
Grant, Robert H.
Journal of College Science Teaching, v35 n2 p6 Oct 2005
2005-10-01
Descriptors: Foreign Countries; Ichthyology; Paleontology; Biology; Discovery Processes; Science History; Evolution; Diaries; Ichthyology; College Science; Inquiry; Science Instruction; Case Method (Teaching Technique)
Abstract: Through a series of fictionalized diary entries based on Marjorie Courtenay-Latimer's own writings, this case recounts the "discovery" in South Africa in 1938 of a fish believed to be extinct for over 70 million years. The case was developed for use in an introductory freshman biology course. In this setting, it could be used as a general introduction to the nature/methods of scientific inquiry at the very start of a semester or later in the semester as an introduction to the topic of evolution. Additionally, this case could be modified for use in a number of upper-level biology courses such as ichthyology (as a springboard into a discussion of ancient fish lineages or fish evolution), evolutionary biology (as an introduction to evolutionary relationships between classes of animals), or conservation ecology (as an illustration of the issues involved in studying rare animal species).

6. Response of Fish to Chemical Signals in Water: A Constructivist Approach (EJ745141)
Schlenker, Richard M.; Schlenker, Karl R.
Science Activities: Classroom Projects and Curriculum Ideas, v41 n4 p44-51 Win 2005
2005-00-00
Descriptors: Science Activities; Science Instruction; Hands on Science; Teaching Methods; Constructivism (Learning); Animal Behavior; Animals; Ichthyology
Abstract: In contemporary science education, the trend is to engage students in hands-on activities in which they must manipulate equipment and gather data in an effort to answer questions. Hands-on experiences may turn out to be meaningless unless the experiences are well designed, planned, and focused so that students are guided to construct accurate mental constructions. A superior approach is to engage students in activities in which variables are controlled and general research procedures are used. In this article, the authors present a science activity that will help students understand how fish species find and identify each other--a potentially critical element in their survival when a predator-prey relationship exists between two species. The activity involves a real-world problem that the authors believe is a good tool both to motivate students (Roth 1991) and to engage them in research. Students are required to collect and organize data on two fish species, examine the data mathematically, draw conclusions about the organisms with which they work, and extrapolate to other environments.

7. The Fish Kill Mystery: Learning about Aquatic Communities (EJ752479)
Kosal, Erica F.
Journal of College Science Teaching, v33 n4 p36-40 Feb 2004
2004-02-00
Descriptors: Heuristics; Case Studies; Interdisciplinary Approach; Ecology; Environmental Education; Etiology; Ichthyology; Problem Based Learning; Classroom Techniques; Behavioral Objectives
Abstract: This paper presents a case where students can learn about aquatic communities. In this case, students speculate on what may have caused a major fish kill in an estuary in North Carolina. In the process, they explore how land runoff and excess nutrients affect aquatic communities. They also learn about the complex life cycle of the dinoflagellate Pfiesteria.
8. Salmon Farming and Salmon People: Identity and Environment in the Leggatt Inquiry (EJ787790)
Schreiber, Dorothee
American Indian Culture and Research Journal, v27 n4 p79-103 2003

Descriptors: Indigenous Populations; Community Attitudes; Foreign Countries; Ichthyology; Animal Husbandry; Hearings; Critical Theory; Tribal Sovereignty; Discourse Modes; Discourse Analysis; Indigenous Knowledge; Sustainable Development; Community Surveys; Social History
Abstract: In October of 2001, the Leggatt Inquiry into salmon farming traveled to four small communities (Port Hardy, Tofino, Alert Bay, and Campbell River) close to the centers of operation for the finfish aquaculture industry in British Columbia. In doing so, it gave local people, particularly First Nations people, an opportunity to speak about salmon farming using their own vocabularies, styles of speaking, and forms of knowledge. Their testimony, however, was about much more than salmon farming. In fact, most of the talk at the inquiry focused upon people's sense of place and community, and their understandings of their way of life. In particular, the inquiry brought to light the legal and political context in which the salmon farming industry operates. This paper focuses on narratives that in technical and scientific circles would probably be considered rambling, anecdotal, and off the subject. The author's analysis of the Leggatt Inquiry tries to give voice to the Native people who appeared at the inquiry by showing that, while they are certainly the victims of continued intrusions into their territories and ways of life, they are not passive bystanders in the process. Instead, the aboriginal people who spoke about salmon farming at the inquiry creatively and strategically employed a variety of devices that would help others see the controversy over salmon farming as they themselves did.
