Helping to establish trout in rivers and streams in Bolivia has won a humanitarian award for a Richfield couple from the Ezra Taft Benson Agricultural and Food Institute.

Mr. and Mrs. Bobby Williams have contributed 300,000 trout eggs to a project to re-establish the fish as a food source and cash crop.The Bolivian waters once contained fish, but they were killed out when area residents dynamited Lake Titicaca to obtain food.

The Williams became interested in the project when they approached the institute to ask for help in refining a recipe for canning trout. They own the Trophy Fish Ranch east of Richfield and have expanded their fish-raising business to include canning.

The Benson Institute helps to establish agriculture-related programs in underdeveloped countries.
