318 DOMESTICATED TROUT. 



fish, in the form of a long, narrow, adhesive ribbon, with 

 the appearance of having been packed very compactly. 

 In a few moments it swells to such a size that you could 

 not get more than one third of it into the fish again. 



After the expansion is completed, an average roe of a 

 six-ounce Missisquoi River perch will measure about 36 

 inches in length by about 3 inches in width, or 108 super- 

 ficial inches. I estimate that there are about 64 eggs to 

 the square inch, which would give 6,912 eggs to the roe. 

 I do not claim any exactness in this estimate, but I think 

 it approximates the truth. 



There is one more feature about the spawn in question 

 which should be noted. After a little while it loses its 

 tendency to stick to foreign substances, although it still 

 adheres together, and it can be taken up in the hand and 

 carried about, and even handled quite roughly, without 

 damaging the eggs.
