238 APPENDIX. 



relative to the transport and the hatching of the 

 ova, as well as to the production of fry, are very 

 satisfactory ; they may be approximately estimated 

 at one-third of living fish, in proportion to the 

 quantity of ova collected ; and the increase of fish 

 in the rivers and ponds has been confirmed by 

 numerous testimonies, and the number of pisci- 

 cultural associations has rapidly increased." 



The results are very elaborately shown in four- 

 teen tabular statements prepared with great minute- 

 ness (we only take the last year's returns), and 

 from these it appears that 19,449,400 ova had 

 been collected, of eight different species of fish, at 

 a cost of 22001. If we estimate thirty- six ova to 

 have cost one penny, this quantity would amount 

 to 225U Is. 9d. The report states that "they 

 may be approximately estimated at one-third as 

 living fish/' thus producing twelve living fish for 

 one penny, or 6,483,133 living fish for the sum of 

 2200/., and introduced into the various rivers and 

 waters of France last year ; that is, if in England 

 we take 300,000 salmon ova to have been col- 

 lected at thirty-six for a penny, the cost would be 

 34/. 14s. 5d., at a similar rate to those produced in 

 France ; and, taking one-third to be living fish, the 

 result should be an increase of 100,000 young 

 salmon, or twelve for a penny. 



With such statements before us, and after a 

 period of ten years' experience, it would be diffi- 

 cult to arrive at any other conclusion than that the 

 experiments had proved, as they are stated to have 

 been, " very satisfactory." 



M. Coumes states further, that the propagation of
