Fishing and Fish Conservation – Not Mutually Exclusive!

Hello, Frank Indiviglio here.  Many aquarists, myself included, enjoy fishing from time to time.  I come home from each fishing trip with new insights and observations…and some of my most interesting aquarium pets have been native species taken by net or hook while angling.  But in these times of plummeting fresh water and marine fish populations, one cannot help but question the ethics of recreational fishing.  Well, fear not – there are many ways that responsible anglers can continue fishing and support conservation in the process.

Tag and Release Programs

Most fishes remain out of sight (at least to us!), and many travel great distances. Tagging programs are, therefore, considered by ichthyologists to be vital in planning effective conservation strategies 

When proper hooks and careful release techniques are employed, survival rates for released fishes are quite high.  Anglers can participate in a number of conservation programs that utilize tags to track fish movements.  By physically applying these tags and reporting any tag-bearing fishes that are taken, both recreational and commercial anglers have generated a wealth of important data would be otherwise difficult to obtain.

Much of value has already been learned.  For example, tag returns have revealed that the Atlantic Bluefin Tuna, one of the world’s most highly endangered species, crisscross the Atlantic Ocean, traveling from Norway to New England and the Bahamas.  International cooperation is therefore required if protection is to be effective.

Volunteer Programs in the USA

The American Littoral Society maintains the USA’s most ambitious fish-tagging program.  Since its inception in 1965, the program, relying upon volunteer anglers, has generated information on the mortality rates, breeding and feeding grounds, longevities and migration routes of a wide variety of fish species.

PikeThe wildlife agencies of individual states often host volunteer-based tagging programs as well.  You can find out what your state is doing in this regard, and how to become involved.

Being born with a deep interest in animals might seem unfortunate for a native Bronxite , but my family encouraged my interest and the menagerie that sprung from it. Jobs with pet stores and importers had me caring for a fantastic assortment of reptiles and amphibians. After a detour as a lawyer, I was hired as a Bronx Zoo animal keeper and was soon caring for gharials, goliath frogs, king cobras and everything in-between. Research has taken me in pursuit of anacondas, Orinoco crocodiles and other animals in locales ranging from Venezuela’s llanos to Tortuguero’s beaches. Now, after 20+ years with the Bronx Zoo, I am a consultant for several zoos and museums. I have spent time in Japan, and often exchange ideas with zoologists there. I have written books on salamanders, geckos and other “herps”, discussed reptile-keeping on television and presented papers at conferences. A Master’s Degree in biology has led to teaching opportunities. My work puts me in contact with thousands of hobbyists keeping an array of pets. Without fail, I have learned much from them and hope, dear readers, that you will be generous in sharing your thoughts on this blog and web site. For a complete biography of my experience click here.
