  • Objectives
    On completion of the course, students should be able to appreciate the basic physiology, diversity and evolution of fishes. Diversity is especially prevalent; examples from diverse groups are used in order to provide a good overview of fish biology.
  • Academic Title
    The course is pitched at Level 3, according to national guidelines. The course is awarded and accredited by the Institute for Animal Care Education. On completion of the course, students will be eligible for full membership of the Institute and consequently.
  • Course description

    Assessment

    Assessment takes the form of basic questioning (30% of total mark) and report writing (70% of total mark). Students will be provided with guidance as to what is required in assessment. Assistance will be available from UK Open Learning via telephone or e-mail
