The management of the ichthyofauna
On the validity of the "Catch and Release" there can be no doubt if well managed, naturally. This is a fundamental point.
The most comprehensive work is the U.S. statement. Fish and Wild Life Service published on 1976 (investigation which summarizes 14 studies carried out between 1956 and 1976 on thousands of trouts observed for 20/25 days from their capture and immediate release). These are some of the conclusions:
- death occurred in the first two days from the release from the capture.
- mortality observed was almost always due to the ingestion of artificial until the esophagus or lesions of the gills
- the mortality rate was from 30 to 70% for natural baits
- less than 10% for artificial lures
- by 4% in fly fishing
- There were no significant differences with the fishhook with or without barbs.
