This course is an introduction to the fascinating and diverse world of fish. With over 21,000 species there is no other group of vertebrates where you will find such a diversity of body forms and colors, so many peculiar ways of making a living, or even so many bizarre ways of reproducing. For over 400 million years, fish have been filling all the aquatic habitats from the bottom of the ocean to the headwaters of mountain streams. Ranging in size from a few mm to over 10 meters they offer an amazing array of forms and functions and are vital as food for millions of people. However, fish species are going extinct especially freshwater species, many other species are endangered or threatened and most commercial species are overfished.
Thus, the future of many species is bleak suggesting the need for a broader understanding of the importance of fish as a vital source of food/protein, as major trophic players in all aquatic ecosystems, as the “canaries” of the ocean, and as the major transporter of nutrients/biomass back to impoverished watersheds. Commercial and recreational fishing industries, diving and snorkel travel, hobby and commercial aquariums are all driven to various extents by the uniqueness and allure of fish. The purpose of this course is to introduce students to the natural history, biology, and conservation of fish so they know why fish are important and they understand the need for habitat preservation and sustainable catches.
