The Marine Institute (formerly the Salmon Research Agency of Ireland and the Salmon Research Trust) operate permanent complete fish traps in the Burrishoole catchment, Co. Mayo, Ireland, as part of a program of long term ecological research (LTER). Data has been collected since 1970. All migrating diadromous fish are enumerated between their marine and freshwater habitats. The data contains census data, fecundity data, and data on the proportion of potential wild and captive-bred (ranched) Atlantic salmon (Salmo salar L.) sampled in the Burrishoole fish traps. The text file contains R code used in the analyses of relative reproductive success between captive and wild-bred Atlantic salmon and can be used to repeat such analyses. The associated text file also contains code relevant to calculating population productivity and the unbiased estimators of relative reproductive success. The Burrishoole fish traps have the following locations: Salmon leap: 53.920323, -9.584348 and Mill Race: 53.924081, -9.571727. As records do not specify which trap the specimens were sampled in, a midpoint of 53.922202 -9.578038 has been applied as the location data in the data distribution.
