Alive specimens belonging to Tellimya tenella (Lovén, 1846) were recorded for the first time in Adriatic Sea. Up to date, only few pleistocene fossils or empty valves of this species had been reported in Italian waters., Žive jedinke Tellimya tenella (Lovén, 1846.) prvi su puta zabilježeni u Jadranskom moru. Do danas je u talijanskim vodama zabilježeno svega nekoliko pleistocenskih fosila ili praznih ljuski ove vrste.

Annex 5 presents the expert evaluation of Targeted Product quality and gaps in the input data sets.

The second Mediterranean Data Adequacy Report (DAR) is completing the development of concepts and methodologies initiated in the Literature Review and in the first Data Adequacy Report. The aim of this DAR is to document the reliability and utility of the existing monitoring system at the sea basin level and it identifies the gaps, prioritizing them. This DAR describes the final methodological approach for the MedSea Checkpoint based upon ISO and INSPIRE principles and the development of indicators. The indicators are constructed directly from the Checkpoint metadatabase, which contains information on the upstream data used to construct the Challenge products. For each Challenge product, Checkpoint information on What, Why, Where, When, How data have been used to develop targeted products is given and statistically analysed.

The targeted products were divided in two main tasks, based on the Challenge 5 Objectives: TASK 1) fishery datasets of fish landings, discard and by-catch (ETP species) for assessing the quality, extracting the synergies and identifying the gaps in the fishery data collection systems in the Mediterranean Sea; TASK 2) maps showing the extent of the trawling fishing grounds in order to identify the areas that have been most disturbed by bottom trawling and the changes in the level of disturbance over the past 10 years. The aim was to identify the gaps in fishing vessels’ tracking systems operating in the Mediterranean Sea and to evaluate the impact of trawling on the seabed. For the first task, the landing, discard and by-catch data were compiled using information gathered from the DCR/DCF, FAO-FishStat and ICCAT databases. For the second task, the impact of trawling on the seabed was estimated using data recorded by the Vessel Monitoring System (VMS), the Automatic Identification System (AIS) and the ESIF system developed within the EU project “Energy Saving in Fisheries”, financed under the framework of the open call for Tenders Fish/2006/17-LOT3. In particular, the ESIF system data were included both as an example of an alternative monitoring system and to validate the VMS and AIS data. Biota-biology and seabed layers (seabed habitats and substrate) were considered to evaluate the impact on sensitive habitats.

Nel presente rapporto vengono riportati i risultati relativi alla fase "durante operam" degli studi di carattere ambientale condotti dal CNR-ISMAR UOS Ancona nell'ambito dell'Accordo tra codesto Istituto e l'Autorità Portuale di Ancona (Prot. 0021161 del 27/03/2015) e riguardano in particolare la verifica delle dinamiche sul trasporto dei sedimenti del largo e lungo la fascia costiera, gli effetti del dragaggio sui sedimenti marini e sugli organismi sentinella (Mytilus galloprovincialis). Tali risultati sono confrontati con quanto rilevato con le indagini integrative relative alla fase di pre-survey condotta per le operazioni di escavo della Banchina 26 del Porto di Ancona (Fabi et al., 2015).

Nel presente rapporto vengono riportati i risultati finali relativi agli studi di carattere ambientale condotti dal CNR-ISMAR UOS Ancona nell'ambito dell'Accordo tra codesto Istituto e l'Autorità Portuale di Ancona (Prot. 0021161 del 27/03/2015) e riguardano, in particolare, gli effetti del dragaggio sui sedimenti marini e sugli organismi sentinella (Mytilus galloprovincialis) alla fine dei lavori di escavo della Banchina 26 del Porto di Ancona, iniziati il 23/06/2015 e terminati il giorno 04/08/2015. Lo studio ha riguardato tre fasi (pre-survey, durante lavori di escavo e post-operam) e i risultati relativi alle prime due sono stati prodotti in Fabi et al. (2015 e 2016). Nella presente relazione sono riportati quelli ottenuti nella fase di post-operam confrontati con i precedenti al fine di verificare eventuali cambiamenti sulle dinamiche dei sedimenti portuali e sugli organismi sentinella indotti dalle operazioni di dragaggio.

A variety of conservation policies now frame the management of fishing activity and so do also the spatial planning of different sectorial activities. These framework policies are additional to classical fishery management. There is a risk that the policies applying on the marine system are not coherent from a fisheries point of view. The spatial management of fishing activity at regional scale has the potential to meet multiple management objectives, on a habitat basis. Here we consider how to integrate multiple objectives of different policies into integrated ocean management scenarios. In the EU, European Directives and the CFP are now implementing the ecosystem approach to the management of human activity at sea. In this context, we further identify three research needs: • Develop Management Strategy Evaluation (MSE) for multiple-objective and multiple-sector spatial management schemes • Improve knowledge on and evaluation of functional habitats • Develop spatially-explicit end-to-end models with appropriate complexity for spatial MSE The contribution is based on the results of a workshop of the EraNet COFASP.

Fishing of Nassarius mutabilis is by far the most important activity carried out by artisanal fisheries in the central and northern Adriatic Sea, accounting for more than 35% of total fishing effort and yielding from 2000 to 3000 t of landings each year. This gastropod is targeted from the beginning of autumn to the end of spring using basket traps. Despite its importance under a socio-economic point of view, the scientific studies on the biology and ecology of this species are very scarce and the failure of the current management measures could also be attributed to the scarce knowledge on the biology of this species in the area. Taking this statement into consideration, the results of the present study contribute to fill a few existing gaps and may be useful to improve the management measures currently in force. Samples were collected from March 2006– March 2008 during monthly fishing surveys and carried out using basket traps in the central Adriatic Sea. A total of 383 males (size range 7–29 mm SH) and 504 females (size range 15-32 mm SH) were caught. Mean SH (± SD) of males was 15.84±3.57 mm and mean SH of females was 25.31±3.06 mm. A significant difference in the biometric characteristics between the two sexes was discovered. The condition index (CI) showed similar seasonal trends for both sexes, with a decrease from late winter to spring followed by an increase from summer to fall - early winter. The minimum values were recorded in summer and the maximum ones in winter, following an opposite trend in respect to water temperature. In the males this trend was observed starting from size classes larger than 11 mm SH, hence this size might be very close to the size at first sexual maturity. The size at first maturity hypothesized for females (16-20 mm SH) agrees with the minimum landing size (MLS) currently established for this species (20 mm SH). The absence of small females (SH < 15 mm) and large males (SH > 23 mm) leads to suppose a sex reversal from male to female at around 20 mm SH. On this basis, the management measure of MLS leads to the selective retention of females and, hence, to a sexual gap between the two sexes with possible consequences on the biology of the species and the resilience of the stock. The peaks of CI observed for males and females confirmed that the spawning season of this gastropod occurs in late winter – early spring, according to the abundant presence of egg capsules attached to submerged substrates in that period at sea. Consequently, from a management point of view, it would be advisable to shorten the fishing season that at present extends from fall to later spring., Lovljenje morskog puža Nassarius mutabilis je daleko najvažnija djelatnost malog priobalnog ribolova u središnjem i sjevernom Jadranu, što čini više od 35% ukupnog ribolovnog napora s prinosom od 2000 do 3000 tone svake godine. Ovaj puž se lovi od početka jeseni do kraja proljeća pomoću vrše. Unatoč njegovoj društveno-ekonomskoj važnosti, znanstvene studije o biologiji i ekologiji ove vrste su vrlo rijetke, stoga se neuspjeh trenutnih mjera upravljanja također može pripisati oskudnom znanju o biologiji ove vrste u navedenom području. Rezultati ovog istraživanja pridonose rješavanju nekoliko postojećih nedostataka i mogu biti korisni za poboljšanje mjera upravljanja koje su trenutno na snazi. Uzorci su prikupljeni pomoću vrše (košare; pletene stupice) u razdoblju od ožujka 2006. do ožujka 2008. godine tijekom mjesečnih istraživanja u središnjem Jadranu. Ukupno su uhvaćena 383 mužjaka (raspon veličina 7-29 mm SH) i 504 ženke (raspon veličina 15 - 32 mm, SH- visina školjke-puža). Srednja visina puža (± SD - značajna razlika) mužjaka iznosila je 15,84 ± 3,57 mm, a srednja visina kućice ženki je iznosila 25.31 ± 3.06 mm. Otkrivena je značajna razlika biometrijskih karakteristika između dva spola. Indeks stanja (CI) pokazao je slične sezonske trendove za oba spola, s padom od kraja zime do proljeća, nakon čega slijedi porast od ljeta do jeseni odnosno početkom zime. Najmanje vrijednosti zabilježene su u ljeto, a maksimalne zimi, što predstavlja suprotni trend u odnosu na temperaturu vode. Kod mužjaka je ovaj trend uočen počevši od kategorije visine kućice veće od 11 mm, pa bi stoga ove veličine mogle biti vrlo blizu veličini puža kod prve spolne zrelosti. Hipotetski veličina ženki kod prve spolne zrelosti (visina kućice 16-20 mm) se slaže s veličinom minimalnog ulova (MLS) trenutno uspostavljenog za ovu vrstu morskog puža (visina kućice 20 mm). Odsutnost malih ženki (visina kućice 23 mm) dovodi do pretpostavke da se preokret kod muškog i ženskog spola odvija kada kućica dosegne visinu od oko 20 mm. Na temelju toga, mjera upravljanja bi trebala dovesti do selektivnog zadržavanja ženki, a time i do spolnog razdvajanja s mogućim posljedicama na biologiju vrste i održivost stocka. Vrhunac indeksa stanja uočenog kod mužjaka i ženki je potvrdio da se mriještenje ovog mekušca javlja krajem zime - početkom proljeća, u skladu s obilnom prisutnošću kapsula jajašaca pričvršćenih na potopljene supstrate u tom razdoblju. Prema tome, s gledišta gospodarskog upravljanja, bilo bi poželjno da se skrati ribolovna sezona koja se u ovom trenutku proteže od jeseni do kasnog proljeća.

The observation of a new species in a new area represents the first opportunity to follow and study the dynamics of colonization and understand how a new species arrives, what are its movements and its potential impact. The discovery of a large number of species outside their usual area of distribution is probably the most important reason for the increase in perceived biodiversity of the Adriatic ichthyofauna. A total of 4 specimens of T. picturatus were caught in the period May-June 2011 in the surroundings of an offshore gas platform in the Northern Adriatic Sea. Scientific literature depicts this species as rare in the Adriatic Sea, indicating and suggesting the Pomo Pit (Central Adriatic Sea) as the Northern latitudinal limit of its distribution. On this basis, this paper reports the first record of T. picturatus in the Northern Adriatic basin, suggesting an expansion of its spatial distribution., Promatranje nove vrste u novom prostoru predstavlja prvu priliku praćenja i proučavanja dinamike kolonizacije, te razumijevanje kako nova vrsta pristiže u prostor, kako se u njemu kreće i njen potencijalni utjecaj na prostor. Otkriće velikog broja vrsta izvan njihovog uobičajenog područja raspodjele je vjerojatno najvažniji razlog za povećanje percipirane bioraznolikosti Jadranske ihtiofaune. Ukupno 4 primjerka šaruna golemog, T. picturatus, su ulovljeni u razdoblju od svibnja do lipnja 2011. u okolici platformi plina u sjevernom Jadranu. Znanstvena literatura opisuje ove vrste kao rijetke u Jadranu, što potvrđuje Jabučku kotlinu (srednjeg Jadrana) kao sjevernu granicu njegove raspodjele. Na temelju toga, u ovom radu se iznosi prvi nalaz šaruna golemog, T. picturatus, u sjevernom jadranskom slivu, što ukazuje na širenje njegove prostorne raspodjele.
