EU MEDIterranean Acoustic Survey on Small Pelagics “MEDIAS” GFCM, ISMIR, September 2008

Current status (E.U. states) In the Mediterranean 5 direct surveys on small pelagic fish are regularly held at least during the last decade. Iberian coast (IEO) ECOMED Gulf of Lions (IFREMER) PELMED Adriatic Sea (ISMAR) & Slovenia Sicilian channel & Malta (IAMC) ANCHOVY Aegean Sea (HCMR) ANCHOVY Concerning The current status of the small pelagic surveys in the Mediterranean regarding EU countries we have 5 direct surveys regura……

These surveys mainly target on anchovy and sardine Cover the major stocks of these species in the Mediterranean European Union waters In the new DCR all EU acoustic surveys will be funded. A workshop took place in Athens between 25 and 26 /2/2008. During this meeting a common protocol for all the EU Mediterranean acoustic surveys has been adopted In the framework of DCR this Pan-Mediterranean acoustic survey will be coordinated by a steering committee which has been approved by RCM Med

Echo sounder parameters Split beam Frequency for assessment (kHz) 38 Complementary frequencies (kHz) 120, 200 depending on availability. Pulse duration (ms) 1 ms Beam Angle Should be reported Ping rate Maximum depending on depth Calibration (No per survey) A calibration report should be given (Annex III) One calibration per survey Threshold for acquisition (dB) -80 Threshold for assessment (dB) -70 to -60 (reported) Survey design Transects design Perpendicular to the coastline/bathymetry, otherwise depending on topography The survey design should be reported. Inter-transect distance (NM) Max <=12 NM. Time of day for acoustic sampling Day time. Otherwise, in cases of time limitation and if echo allocation into species does not depend on school shape identification (in this case justification of the accuracy of results will be presented) EDSU (nm) 1 NM Distance from the coast according to the Bottom depth (min, m) At least 20 m bottom depth, minimum 10 m of echo-sampling. Echo sounding depth (min, m) Depending on the draught of RV. Should be reported Echo sounding depth (max, m) recording. 200 m Vessel speed 8-10 knots Software for analysis Movies and/or Echoview File format *.hac Inter - transect Acoustic energy in the inter-transect track will not be taken into account Applied TS (dB) Keep historical TS equations. Echo partitioning into species Echo trace classification based on echogram visual scrutinisation Direct allocation and allocation on account of representative fishing station

Abundance estimates Abundance indices estimated Total fish NASC per EDSU Target Species NASC per EDSU Biomass per EDSU per target species Numbers per EDSU per target species Number/age/Target species Biomass/age/Target species Maps and charts Point maps of total fish NASC Point maps of target species in NASC/mile; biomass / mile. Catch compositions of the hauls, pie-charts indicating biomass per species Common database Issues of common database will be established by the participants Discussed the possibility to collaborate with the Atlantic survey Fish sampling Target species Anchovy, Sardine Other species Biological data for all species in the pelagic community: Length-Weight relationships; Length distribution. Fishing gear Pelagic trawl, Codend and trawl characteristics should be reported. Max Codend mesh size = 24 mm (side of mesh = 12 mm). Duration of haul Minimum 30 min for unknown echoes Vessel speed during fishing 3.5 – 4.5 knots Sampling intensity, no of hauls The total number of hauls has to be adequate to ensure identification of echo traces obtain length structure of the population obtain species composition get biological samples Biological and oceanographic parameters Length All species: Total length (TL), Length frequency distribution (0.5 cm) Age readings, ALK Sardine, Anchovy: Mean TL at age Sample sizes according to the new DCR. Length - Weight All pelagic species Oceanographic. Parameter (CTD) Minimum 3 CTD per transect or grid of stations with density adequate to describe the oceanography of the area. Minimum variables: T, S

In the framework of the DCR at least one meeting will be held every year During these meetings the MEDIAS survey will be further harmonized.
