Ichthyology Course: Fish Biology and Identification at Tarleton State University, Thesis of Ichthyology

Tarleton State University (TSU)Ichthyology

An overview of a university course titled 'mw in science 213j: ichthyology' offered at tarleton state university. The course covers the biology of fishes, with a focus on diversity and evolution, morphology, ecology, physiology, life history, behavior, systematics, and biogeography. Students are expected to master various concepts related to fishes, including speciation, phylogeny, life history, biogeography, ecology, osmoregulation, reproductive mode, and biodiversity. Laboratory work involves fish anatomy and identification, and assessments include written exams, practical exams, quizzes, and assignments.

Course Overview: A study of the biology of fishes, emphasizing diversity and evolution,
morphology, ecology, physiology, life history, behavior, systematics and biogeography.
Laboratory work focuses on fish anatomy and identification and taxonomy of groups important
in the local fauna. This is not a class about fishing!
Broad Knowledge Outcomes:
Students are expected to show mastery in the broad area of ichthyology (fish biology), with
special reference to evolutionary relationships, adaptive morphological attributes, biogeography,
ecology, and physiology. Mastery is also required in laboratory and field based activities, with an
emphasis on anatomy and identification of fish species.
Students should be able to:
1. Distinguish families and higher taxonomic groups of fishes with respect to their
physical features.
2. Draw patterns of phylogenetic relationships among various groups of fishes and to
understand the evolutionary significance of features mapped on these phylogenetic trees.
3. Identify selected fish specimens to the level of species using standardized laboratory
methods, dichotomous keys and other descriptive literature.
4. Compare and contrast a variety of aquatic habitats with respect to the kinds of fishes
present, their physiological/ecological features, and biodiversity.
5. Describe the form and function of systems involved in respiration, thermoregulation,
food acquisition, locomotion and buoyancy control.

  5. Describe the form and function of systems involved in respiration, thermoregulation, food acquisition, locomotion and buoyancy control.

The degree to which students have learned this material will be evaluated by (a) two written lecture exams and a final comprehensive examination, (b) two laboratory practical exams, and (c) various lecture and labs quizzes and assignments. Course Objectives

  1. Define, describe, and explain the following concepts as they relate to fishes: speciation, phylogeny, life history, biogeography, ecology, osmoregulation, reproductive mode, and biodiversity. Provide specific examples of fish taxa for these processes and their effects on diversity.
  2. Study live and preserved fish specimens (this and other laboratory/field activities are subject to the availability of in-person study and travel) towards recognition of an array of species, with emphasis on families and species common in Texas. Develop knowledge of the higher categories of fish classification.
  3. Acquire a knowledge of the skeleton and other anatomical components and their functions. Apply information about these structures to an understanding of the functional morphology of fishes, with an emphasis on locomotion, buoyancy control, feeding, respiration, thermoregulation and osmoregulation. Laboratory activities: A. Handling and manipulation of fish specimens and some dissection. B. Osteological study of dried skeletal preparations and cleared and stained fish specimens. C. Identification: Learning to use dichotomous keys and to record specimen attributes commonly used in ichthyology. Identification of a set of “unknown” fish specimens (or photographic images of specimens in the event we revert to on-line study). D. Studying the fishes in the study collection. The emphasis will be on representatives of families occurring in the Texas. Specimens will also be obtained in the field for study in the laboratory. Attendance: You are expected to attend class in-person or via Zoom and watch the recorded lectures. You are responsible for all assigned readings, material and announcements presented in lecture. Contact a classmate for material and announcements you miss. All Friday lectures will be conducted live through Zoom (link is in the first module on Course Canvas site). Additionally, some lectures will be recorded and posted ahead of time (see schedule below for details and specific dates).
