5 Knowledge Transfer KTWS on Shellfish Monitoring, Regulation and Management Sep 13-14, 2012, Portaferry, Northern Ireland. KTWS on Shellfish Production, Processing and Marketing Sep 12-13, 2013, Newry, Northern Ireland. Shellfish KTWS to be continued 2014, 2015 Training CPD Course on Identifying Freshwater invertebrates held at SCENE and Derry CPD Course on Identifying Marine Invasives July 9-10, 2013, Portaferry, Northern Ireland Expressions of Interest for development and delivery of other CPDs to be advertised

6 Research IBIS will deliver 70 years of research through 12 PhD and 34 Masters projects

7 PhD Research at QUB 1. Developing science-based management strategies for environmental and commercial sustainability of native oysters, Ostrea edulis. 2. Developing molecular markers for application in the management of threats from Bonamia ostreae to exploited stocks of the European oyster Ostrea edulis 3. Predicting impacts of near-future climate change on shellfish stock management 4. Impacts of the natural spread of non-native oysters and interactions with native oysters 5. Developing science-based management strategies for improving yield of blue mussels, Mytilus edulis, in benthic cultivation

8 MPhil Research at QUB 1. Factors influencing fecundity in the European eel (C) 2. Operating costs in the Lough Foyle oyster fishery (C) 3. Size-fecundity relationships in the management of the European lobster (C) 4. Lipid content of the European eel when infected with the swim bladder nematod (C) 5. Interactions between shorebirds and aquaculture in Carlingford Lough (C & ongoing) 6. Best practices for C. gigas producers 7. Aquaculture influences on wildfowl populations on Lough Foyle 8. Production grow out strategies for commercial development of European Perch 9. Governance of the marine environment around the island of Ireland 10. Marine acoustic environment and megafauna around Inishowen Peninsula 11. Anthropogenic mediated habitat alteration on Lough Derg brown trout genetic structure

9 Developing best practice for O.edulis fisheries production in Loch Ryan Lawrence Eagling A project supported by the European Union's INTERREG IVA Programme managed by the Special EU Programmes Body

10 Objectives To analyse the historical records of the Loch Ryan fishery and current management To determine the current stock of the Loch Ryan oysters and the current fishing effort To assess the reproductive potential of the population To monitor the spat fall and improve techniques for settlement within the Loch

11 So far in first 9 months Studied the Wallace family record books Dredges sampled once a month during fishing season 20 oysters sampled every two weeks for sex ratio and stage of reproduction during breeding season Four lines of ten spat collectors put into Loch in July Shells kept over the summer for analysis using different ageing techniques

13 Developing Best Practices For C.gigas Producers Simon Guist A project supported by the European Union's INTERREG IVA Programme managed by the Special EU Programmes Body

14 Project Aims Provide data to producers to improve husbandry practices to reduce risk of Herpes outbreaks.

15 Moveable Oyster Trestle Experiment A number of French oyster studies suggest that increasing time of exposure to air reduces oyster mortality (Richez, 2012). Two sites different salinity Two trestles containing bags of juvenile oysters on lower shore during spring. One trestle moved to upper shore during summer. Oysters sampled monthly for Herpes virus, mortalities, growth and temperature data.

16 Histopathology and Lab Tank Trials Working with Aquaculture Initiative and 7 farms across NI to produce an intertidal temperature database and to investigate oyster health and condition Conducting Lab trials to assess how varying temperatures and salinities impact oyster stress levels.

17 Interactions between shellfish aquaculture and intertidal bird populations in Carlingford Lough Aoibheann Canavan A project supported by the European Union's INTERREG IVA Programme managed by the Special EU Programmes Body

18 Aim 1 To provide continuing data relating habitat usage, species abundance and species assemblages to the presence of aquaculture vs non aquaculture sites in Carlingford Lough 3000 Diversity of Species & Numbers of individuals n2 n4 s2 sn6 n5 n3 s1 s5 s3 s4 n1 Trestle Dredging Unused Recreation

19 Aim 2 To survey bird faecal matter for the presence of antibiotically resistant strains of E. coli to complement shellfish hygiene protocol. Arose in the mid 80 s and since have spread into the environment and have been found in many species of wild wetland birds.

20 Aim 3 Test the effectiveness of bird deterrents on oyster trestles to prevent roosting and predation on farmed stocks. Evaluate the level of predation by wild birds on oysters.

21 Genomic Tools for the Management of European Oyster (Ostrea edulis) Stocks Mark McCullough A project supported by the European Union's INTERREG IVA Programme managed by the Special EU Programmes Body

22 Project Aims Development and assessment of genetic markers for O. edulis Single Nucleotide Polymorphisms (SNPs) Site in DNA sequence where more than one nucleotide (T or C in above example) is present in the population. Microsatellites Multiple copies of tandem simple sequence repeats (CTT in above example), alleles vary by number of repeated units.

23 To be used for Quantification and spatial patterns of genetic variation (i.e. genetic structure) among flat oyster populations- connectivity and inbreeding Identification of suitable strains for supplemental stocking/restoration in particular areas Monitoring performance (i.e. biological fitness) of translocated stocks in new environments Identifying unique genetic resources Establishing whether there is a detectable genetic basis to differences in B. ostreae tolerance among populations Modified from Launey et al., (2002)

24 Looking for samples Range of sites 50 individuals Ostrea edulis range of sizes Detailed information about the bed grid ref, history, substrate, depth, salinity, temperature We can send boxes and pay postage Contact me

25 IBIS assist environmentally sustainable economic development aquatic resources Benefits of stakeholder collaborations On farm research and development Two way learning process Real applied outcomes Summary
