Nyhed:Hvilken lakse-dødelighed kan du acceptere ved C&R?  Søndag d. 13 juni 2010 - af  Svend erik vardrup   Læst 709 gange. Til dig og andre der tror, at den atlantiske laks elsker en tur på land - igen - og igen - og igen - uden at tage nævneværdig skade. Man skal bare være lidt forsigtig, så går det nok... Men ifølge rapporten her, der er udarbejdet af NASCO (NORTH ATLANTIC SALMON CONSERVATION ORGANISATION) kan dødeligheden ved Catch & Release af atlantisk laks være helt oppe på 80%: - Catch and release recreational fisheries provide an intermediate management strategy between a full retention fishery and fishery closure for populations that are below target levels. Mortality of Atlantic salmon after catch and release has been reported to be highly variable (0 - 80% but in many studies low). Catch and release angling at low temperatures (below 17–18°C) generally shows lower post-release mortalities than at higher temperatures . There is, however, a lack of studies on the survival after catch and release at higher temperatures from release until spawning and there are no studies on its relationship with survival to repeat spawning. Most of the studies that report mortality rates after catch and release have used skilled anglers or artificially hooked already captive fish. This may lead to lower mortality than would be expected if less experienced anglers caught fish. Studies have shown that less than 25% of fish that had been marked upon release after capture by rod and line were caught a second time, and an even lower proportion was caught a third time. Efforts have been made in a number of countries to inform anglers about good catch and release practice e.g. through free instruction videos and advisory leaflets. NASCO has developed guidelines on catch and release (available in both English and French). -Jeg konkluderer ikke, spør` bare om det for dig ville være acceptabelt med en genudsætnings dødelighed på op til 80% - nævnt som max. i rapporten - eller vil du ned på 60% - 40% - eller 20%, før du finder det acceptabelt? Men ingen tvivl, jeg synes bestemt, at det er vidunderligt og imponerende at så mange danskeres forenede kræfter har resulteret i noget der virkelig ligner en reetablering af den danske laksebestand: men vi lystfiskere mangler nogle lige nu nogle helt klare retningslinier for den mest skånsomme genudsætning/de mest skånsomme C & R metoder - og vist også et nærmere kig på kvotesystemet...
