Course background
Fish inhabit virtually all aquatic habitats on our planet, with well over 30,000 extent species ranging in
total length at adulthood from less than half an inch to over 40 feet. These ancestral vertebrates play
critical roles in aquatic and even terrestrial food webs, with astounding diversity in body form and
appearance, lifestyle, physiological characteristics, etc. An exploration into their evolutionary story,
diversity and ecology offers a fascinating foray into how life evolved in the ocean, the role fish play in
aquatic communities, and how these animals cope with the inherent challenges of living in an aqueous
medium, which is exacerbated by increasing exposure to various anthropogenic conservation threats,
such as overfishing and climate change.
Course description and structure
This course will examine evolution/phylogeny, morphology, ecology, natural history and very basic
physiology of fishes from a diverse range of habitats. Focusing on the tremendous diversity among fish
species and habitats, we will continuously return to the question of how fish have evolved
morphologically, behaviorally and physiologically to survive in such a range of conditions and
environments. While the course does not devote extensive direct time to fisheries ecology, context on
global conservation and management issues facing fish populations will provide a backdrop for many of
the course lessons.
The laboratory component of this course will combine observational exercises with experiential hands‐
on activities, demonstrations and excursions in the both the laboratory and field environments. The
chief goal will be to reinforce lessons from the lecture component and develop new skills to serve as an
asset in future coursework (i.e. graduate studies) and/or career endeavors. The course will also involve a
highly interactive teaching environment, where students are expected to play an active role in course
discussions, lectures and activities.
Objectives
Students should walk away from this course with:
 An introductory understanding of the physical and chemical properties of aquatic environments
and the diversity of environments inhabited by fishes.
 An extensive background on the evolution and diversity of fishes, including a core
understanding of phylogeny, systematics and taxonomy.




The ability to provide species example from course lessons, and recognize a variety of fish taxa.
A strong basic understanding of key aspects in fish ecology, including feeding ecology and
predator‐prey dynamics, behavior, habitat, biogeography, etc.
The ability to describe reproductive and life history strategies in fishes.
A familiarity with the primary anthropogenic threats to aquatic biodiversity, and how those
threats affect the survival and fitness of fish at the individual and population level.
This course will also help students hone their:
 Interactive and discussion skills
 Basic scientific writing skills
 Hands-on laboratory skills, such as fish dissection, identification, and collection.
Reading material
Given the integrative approach, no one textbook is required for this course; however, readings will be
assigned from a variety of sources, and made available to students sufficiently ahead of due dates. In
addition, the use of online resources (e.g. video, reference information) will be encouraged. Sources for
course readings will include:
Fishes: an Introduction to Ichthyology (Moyle & Cech, 2007, 5th Edition, Benjamin Cummings Publishers,
744 p. ISBN: 978-0101008472
Ecology of Aquatic Systems (Dobson & Frid, 2009, 2nd Edition, Oxford University Press, 336 p. ISBN: 978099297542
Ecological and Environmental Physiology of Fishes (Eddy & Handy, 2012, 1st Edition, Oxford University
Press, 264 p. ISBN: 978-0199540952
Expectations
The curriculum is tailored to undergraduate students with an interest or concentration in marine and/or
environmental science; specifically ichthyology, vertebrate zoology, physiology/biochemistry, fisheries,
conservation and environmental policy and/or other related disciplines. There are no prerequisites for
this course; however, coursework in environmental science, conservation biology, ecology, and/or
zoology will be helpful.
It is expected that students attend class, and remain alert and engaged. This class will be highly
interactive, and as such, students must keep up with readings and actively participate. For lab activities,
students are expected to be able to work independently as well as in groups.
Evaluation
This course will offer a range of assessments to promote absorption of material and growth while
accounting for diverse learning styles. As with most courses, there will be assignments and an exam,
where the probability of success will increase if students pay attention, do the readings, think,
synthesize information, and clearly communicate what has been learned.
Lecture component
Exam I – in class – non‐cumulative (150 pts)
Species assignment (100 pts)
This assignment will combine observation and research responsibilities. Students will select a fish
species housed at the New England Aquarium, and record observations on morphology, behavior and
lifestyle of this species. How does it move around? Where does it spend the majority of its time relative
to its behavior and body shape/color etc. Then, students will conduct research on this species (at least
three sources cited) on the natal environments and ecology of this species. Predators and prey,
Reproductive strategies, Conservation threats. This report must also generate either a cladogram
(morphological, not genetic) or an evolutionary tree for the chosen species.
Exam II – in class – non‐cumulative (150 pts)
Participation (100 pts)
Participation in our class is critical and expected. Solid participation will require that all assigned
readings are completed and that students are active participants in class, during discussion groups, and
off‐campus experiential/lab activities.
Laboratory component
Attendance and participation in the laboratory will compose 30 points of the laboratory grade, with the
remaining assessment based on the satisfactory completion and performance on 7 lab reports. There
will be no final lab exam or report, in that lessons from the lab component will be accounted for in the
final exam for the course.

Accommodations
The University of Massachusetts Boston is committed to providing reasonable academic
accommodations for all students with disabilities. This syllabus is available in alternate format upon
request. Students with disabilities who need accommodations in this course must contact the instructor
to discuss needed accommodations. Accommodations will be provided after the student has met with
the instructor to request accommodations. Students must be registered with the Ross Center for
Disability Services, UL 211, www.ross.center@umb.edu , 617.287.7430 before requesting
accommodations from the instructor.
Academic honesty
It is the expressed policy of the University that every aspect of academic life‐‐not only formal
coursework situations, but all relationships and interactions connected to the educational process‐‐shall
be conducted in an absolutely and uncompromisingly honest manner. The University presupposes that
any submission of work for academic credit is the student’s own and is in compliance with University
policies, including its policies on appropriate citation and plagiarism. These policies are spelled out in
the Code of Student Conduct. Students are required to adhere to the Code of Student Conduct,
including requirements for academic honesty, as delineated by the University of Massachusetts, and
