R1: Monitoring and Management of Stock 1.1 Undertake stock assessment Assessing stock status in shrimp is known to be problematic for several reasons: shrimp abundance in one year does not give information about stock in the following year probably because >1 generation per year Short life-span high variability in local catches The ICES WG have discussed 3 other potential approaches to stock assessment Surveys using standardised catches from commercial vessels Ad hoc regulation - set reference points based on LPUE data and implement a traffic light system of management measures (currently employed in the Dutch North Sea shrimp fishery) Use indicators of stock status such as a combination of size distribution, maximum length, number of berried females Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk
R1: Monitoring and Management of Stock Ad hoc shrimp fishery regulation Based on already established EU reporting system of log-books and landings data A sub-set of shrimpers provide catch and effort data Averages are calculated and distributed within a short time frame Reference points (minimum monthly LPUE) can be established using expert judgement (a rule of thumb e.g. 75% of average) and previous LPUE data Implement a traffic light system of actions e.g.: LPUE is high => free fishing LPUE is moderate => fishing on higher effort limited Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk LPUE is low => danger for stocks => fishing restrictions
R1: Monitoring and Management of Stock Surveys using standardised catches from commercial vessels simultaneous standardised catches on as many commercial vessels as possible first survey in May/June to catch recruitment wave (10-20 mm), may need special licence for smaller mesh sizes second survey in summer, July/August, this recruitment cohort will now be 30-45 mm in size trawl information collected for each haul (duration, location) employ sieving procedures to identify biomass of different cohorts sub-sampling by scientists for more detailed investigation of stock structure also collect information on egg-bearing females simultaneous recording of by-catch to identify areas with high by-catch for first year it may be necessary to undertake more regular sampling Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk
R1: Monitoring and Management of Stock A combination of indicators of stock status no. of egg bearing females size composition maximum length size distribution of area predator biomass environmental conditions Gives real insight into the drivers of population but Must be carried out by scientists and lack of clarity on how to interpret data or base management actions on these parameters Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk Need to discuss and seek advice on best way forward
R1: Monitoring and Management of Stock 1.2 Develop harvest strategy set reference points on basis of survey data or other set reference points based on LPUE data implement traffic light system of management measures as in Dutch fishery 1.3 Establish fishery management group the producers IFCA representatives Cefas representative (link FMG and WG?) with advice from ICES Working Group 1.4 Seek expert advice ICES Shrimp working group Dutch shrimp fishery experiences (Management plan in information pack) Cefas has participated in the ICES Crangon working group (Andy Lawler) Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk
R1: Monitoring and Management of Stock Dutch shrimp fishery management measures Feb 2011 Weekend prohibition and fishing times The indicator for the stock status is Landings Per Unit Effort (LPUE) in kg/hr Every 4 weeks the average LPUE is calculated from a selected sample of fishing vessels Traffic light system of measures depending on average LPUE. For example if LPUE falls below X fishing is limited to a maximum number of hours per week Separate traffic light levels weeks 1-24 and weeks 25-52 to allow for seasonal differences in catch Maximum percentage of 15% for shrimp residue for each landing Minimum net mesh size Use of sieve nets Development of alternative fishing methods Recognised rinsing/sorting equipment and recognised handling methods (all documented) By-catch monitoring Endangered species monitoring Closed areas for shrimp fishing Maximum vessel capacity Use of prescribed fishing gear only Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk
R1: Monitoring and Management of Stock 1.5 Improve landings per unit effort data hours actually fished not days at sea North Sea fishery advised by ICES to address LPUE data collection (different systems, landings only, data collected) 1.7 Minimise undersized shrimp mortality formalise mesh size of cod end with signed agreements investigate other methods such as processing and handling in Dutch fishery 1.8 Implement a management plan formal document of stock and harvest strategy measures systems of recording, reporting and feedback traffic light management measures, seasonal closures etc Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk

Recommendations for Pink Shrimp All brown shrimp recommendations apply with the additional issues of: Almost no data collected for this fishery Impact on sensitive Annex 1 habitat, Sabellaria spinulosa reefs to be assessed and management plants put in place Lack of expert advice but MSC certified fisheries e.g. Canadian offshore pink shrimp fishery BUT habitat in UK may need extra consideration With only ONE vessel ideal opportunity to develop best practice at minimum cost Marine Ecological Surveys Limited 3 Palace Yard Mews Bath, BA1 2NH Tel: +44 (0) 1225 442211 Email: marine@seasurvey.co.uk www.seasurvey.co.uk
