AMERICAN FISHES IN ITALY.

Table V. — Total Catch in Lake Manate in 1907. 



Failures were noticeable with the salmonoids. I must add, however, that 

 I have had similarly negative results with European salmonoids. It was only 

 in the beginning of this year that there were caught 100 Coregonus marcene, 

 weighing from 0.50 to 2 kilograms. Fry of this species had been introduced, 

 and a large individual was seen only here and there. No fry had been planted 

 in the lake for four years, and the smaller fishes which were caught, weighing 

 800 grams, must have been bred from fishes that had spawned in the lake. 



The sunfish did not increase greatly in this lake; the catches are insignifi- 

 cant and have never exceeded 300 kilograms yearly, i. e., somewhat over 

 I kilogram per hectare. 



I had built great hope on the black bass. Young Micropterus were seen 

 everywhere during the first years. The first catch was made only four years 

 after their introduction, and it increased to 368 kilograms. During the last 

 year, however, it fell to one-half of this quantity, and the present year will 

 show still poorer results. When the black bass was introduced there were 

 quantities of bleak in the lake, and this fish was not caught at all. At the 

 present time it has entirely disappeared. 



Lake Manate yields at present, as formerly, 3,000 to 5,000 kilograms of fish 

 yearly. No benefit was derived from the introduction of new species of fishes,
