| Lisätietoa: | In 1989–1998, vendace larvaeCoregonus albulawere sampled in Finnish lakes following astratified random sampling design. The abundance of young-of-the-year vendace after the firstgrowing season was estimated using catch-per-unit-effort statistics. The number or total area ofnursery places hardly limited the recruitment of vendace in the study lakes. The majorproportion of prerecruit mortality of vendace occurred in the larval phase and larval samplingproduced significant information on young-of-the-year survival. Although larval abundancesand recruitment were clearly associated only in Lake Onkamo, generally high larval abundancewas needed to produce high number of recruits |
