rearing a fish in fresh water;
transferring said fish from fresh water to seawater or saltwater for continued rearing;
wherein an effective amount of beetle powder is administered to said fish in the 10 days preceding and/or in the 10 days following said fish's transfer from fresh water to seawater or salt water.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the fish belonging to the family Salmonidae is from the genus Salmo, Salvelinus, Onchorynchus, and/or Hucho.

### Claim 3 (depends on 2)
