THE NEW ART OF BKEEDING FISH. 77 



have described for packing eggs for transportation, 

 since both modes have resulted satisfactorily. 



To be certain of transporting eggs to arrive in 

 good condition for hatching, it is by no means imma- 

 terial to select the proper period of their development 

 for packing them. Of this I feel assured from nu- 

 merous experiments, at least with regard to the eggs 

 of trout and salmon. Those which are packed in 

 boxes to be sent a long distance, immediately after 

 they have been fecundated, are much more sensible 

 to destructive influences than those which are packed 

 at the period when the embiyo is so developed that 

 thi'ough the shell or membrane its eyes may be per- 

 ceived like two black specks. In fact, this is the 

 best time to transport them ; first, because they 

 support the journey more readily, and next, because 

 it is only then that we can know certainly that they 

 really are fecundated. When the establishment at 

 Huningen comes to be able to furnish eggs to every 

 point in France, where secondary hatching apparatus 

 may need them, we shall conform always to this rule 

 for transportation, with the certainty it will be suc- 

 cessful. Already we have practised it in several de- 

 partments. 



TRANSPORT OF NEWLY-HATCHED FISH. 



The younger the fish are the easier it is to trans- 

 port them a great distance. Even those destined to 

 live in running water, which require it for hatching.
