so 



At what time sliould we place the alevins in the 

 pond, and in what time may we expect them to reach 

 marketable size ? 



The spawning of the California salmon takes place 

 very earl}-, and on acconnt of this precocity it is chosen 

 as the basis for pond cnltnre. With it we are able to 

 complete the cnltnre in one year, a very great advantage 

 which one cannot realize either with the common tront or 

 the rainbow tront, becanse the former grows ver}- slowly 

 and the latter does not spawn nntil April. The eggs 

 of the California salmon, deposited at the end of Octo- 

 ber, hatch in the middle of December. If they are 

 placed at this time in the rearing basin and properly 

 fed, the}' will measnre on an average twelve centi- 

 metres by the middle of Jnly, and will then be very 

 snitable for liberating in the pond. 



If the temperature of the ^-ear has been very high, 

 and the spawning of the carp takes place earl}-, we 

 ma}' doubtless place the salmon in the pond earlier. 



By all means the 3'oung salmon should be placed 

 in the pond not later than in August. At this time a 

 great many of the Cyprinid^ will be sufficiently devel- 

 oped to answer for their food. The fish culturist then 

 proceeds to seine the alevins with a fine net and to 

 place the salmon in the pond which has been well 

 furnished with its food. 



The breeder from this moment should exercise a 

 continual supervision over the pond and assure himself 

 that there is constantl}^ an excess of small fish, for it is 

 essential, in order that the salmon may grow rapidly, 

 that they should find a superabundance of nourish- 

 ment. Besides, one should be careful not to place too 

 many in the pond at a time and thus cause difficulty. 



These young Cyprinida^ do not find favorable con- 

 ditions for their existence in the salmon pond and will 

 become sickl}^ and furnish indifferent food for the 

 young salmon.
