hardly suspect that fishes suitable for food could be found in such 

 muddy, warm water. Yet the Guapote taken from here sold as readily 

 in the market at Granada as did the best fishes from the Lake. Their 

 flesh was firm, white and flaky, and of good flavor. The vitality of 

 these fishes is remarkable. Those in the market are often found to 

 be living after they have been taken from the water for some time. 

 I purchased two of these fishes in the market at Granada one morning, 

 carried them to the hotel, and left them while eating my breakfast and 

 for some half an hour afterwards. I then put them in water, and in a 

 short time they were as lively as ever. This species is certainly worthy 

 of the attention of fish culturists. It grows to a length of about 500 

 mm. In shape it resembles our black bass. It is, however, a thicker 

 fish.
