    This paper not to be cited without prior·reference to the author. International Council for C•M• 1975IM : 26 the Exploration of the< Sea Anadromous and Catadromous Fish Committee Lower ocean survival rates for hatchery-reared salmon(Salmo salar) stocks re1eased in rivers thantheir native streams. by J.A. Ritter Resource Development Branch Fisheries and Marine Service Environment Canada Halifax, Nova Scotia ABSTRACT· The paper presents an analysis of tag returns for hatchery­ reared smolts öf·three genetic stocks released in rivers situated at different distances from their natIve streams. Tag return rates for the releasegroups showa clinaldecrease with the distance the stocks were transplanted from their native streams. This is interprctcd as representing a clinal decrease in ocean survival, the cxtent of which appears to vary with the coastal distance bctwccn.thc rccipient river and the native stream of the particular stock. INTRODUCTION Survival of hatchery-reared salmon smolts to the adult stage varies considerably among release groups. Although some variation in ocean survival can be attributed to the size and quality or health of the hatchery-reared smolt (Carlin 1968; Peterson 1971 and Frantsi et a1 1972) it has been suggested that survival is also dependcnt on the location of the river in which thc smolts are rc~cased (Ritter and Lister 1971 and Ritter 1972). In this paper, further cvidcnce is prcsented that hatchery­ reared smolts experience lower ocean survival rates when released in rivers other than their native strcams. The paper includes an analysis of tag return data for hatchery-reared smolts released in several Maritime rivers, situated at different distances from the \t native streams or the natural migration routes of the parent stocks • .

Angling catches and CPUE of large salmon (>= 63 cm fork length) were down in most rivers in 1993 relative to previous years but effort increased.
