Unpredictable wild-stock supplies and future import restrictions 

 may stimulate rapid development of culture techniques for aquarium 

 fishes. Although detailed economdc data on production are lacking, 

 the profitable freshwater segment of this industry apparently deals 

 effectively with its problems. Culture of marine ornamentals still 

 faces difficulties, and as a result, 80 to 90 percent of the marine 

 tropical fish sold in the U.S. are imported. Potential exists for 

 further development of this type of culture.
