Start year 2017 End year 2021 Funding (€) € 72,000 Website NA Summary Capitalising on a unique archived European lobster biopsy tissue bank collected at Inis Óirr since 2010 (N > 2,300), in addition to new samples to be collected during the duration of the study, this project will: 1) Assess the contribution of the progeny of released female lobster from spawning cohorts sampled from 2010 to the Inis Oirr (source area) and neighbouring fisheries in 2016, 2017 and 2018. Generated information will be used to estimate larval dispersal, recruitment patterns, quantifying/measuring the impact/contribution of V-notching to local stock abundance; 2) To further elucidate the biology of the lobsters off Inis Óirr island in respect of stock abundance, effective population size Ne, sex ratio, recruitment site fidelity, potential differential contribution of individuals of distinct age/size classes to stock recruitment and to compare the genetic population parameters obtained to the sister NELCO project in Northern Ireland; 3) Establish pedigrees beyond parent-offspring relationships (i.e. un-sampled parents such as brothers, sister, uncles, aunts) as precursors to estimate population quantitative biological parameters including heritabilities for size and growth rate; 4) To assess dispersal/residency patterns of lobsters (adults and larval dispersal) based on parentage assignment of captured lobster in the Inis Óirr and neighbouring fisheries, relating these to oceanographic parameters and habitat topology; 5) Support/confirm genetic data on individual movement/dispersal by comparison data derived from biophysical oceanographic models of larval dispersal. The answers to these questions will provide much needed information on adult lobster behaviour that can be translated into management and conservation measures for this important biological resource in Ireland.
