Abstract:
The findings of this project indicate that the optimum combination of age and season of introduction for hatchery-reared roach, chub and dace to small rivers was to stock 1+ (F2) fish in autumn. Therefore rearing of coarse fish on Agency fish farms for the purpose of fishery rehabilitation should continue to focus on production of 1+ fish for autumn release. Persistence rates of stocked fish in the target reaches were in any case very low and it is recommended that where the length of river in which a fishery is to be restored is 5km or less, methods other than restocking are employed.
