Fisheries and Biodiversity
First section Fisheries and biodiversity Photo from MiPAAF archive Chapter 2 Ecological aspects Italian seas and the subdivision of the Mediterranean Sea in GSA Considerations on data collection for the evaluation of living resources and the monitoring of fisheries on the fleets that operate in the Mediterranean Sea determined the subdivision of the latter in a series of reference areas for both management activities and scientific surveys. Such areas represent a compromise among legislative, geographic and environmental aspects. The Mediterranean Sea was subdivided in 30 sub-areas, named GSA (Geographic Sub Areas). The term “sub” refers to the fact that the Mediterranean Sea is one of the 60 Large Marine Ecosystems on the planet. Geographical Sub-Areas in the GFCM area were established amending the Resolution GFCM/31/2007/2, on the advise of the GFCM Scientific Advisory Committee (SAC). The 30 areas largely differ in size and characteristics. The geographic division of fisheries areas in the Mediterranean Sea is still evolving and is subject to periodical improvement by SAC. 1 Northern Alboran Sea 11.2 Sardinia (east) 22 Aegean Sea 2 Alboran Island 12 Northern Tunisia 23 Crete Island 3 Southern Alboran Sea 13 Gulf of Hammamet 24 North Levant 4 Algeria 14 Gulf of Gabes 25 Cyprus Island 5 Balearic Island 15 Malta Island 26 South Levant 6 Northern Spain 16 South of Sicily 27 Levant 7 Gulf of Lions 17 Northern Adriatic 28 Marmara Sea 8 Corsica Island 18 Southern Adriatic Sea 29 Black Sea 9 Ligurian and North Tyrrhenian Sea 19 Western Ionian Sea 30 Azov Sea 10 South Tyrrhenian Sea 20 Eastern Ionian Sea 11.1 Sardinia (west) 21 Southern Ionian Sea 17 2.1 Environmental characterisation of fishing areas 2.1.1 GSA 9 - Ligurian and Northern Tyrrhenian Seas Relini G., Sartor P., Reale B., Orsi Relini L., Mannini A., De Ranieri S., Ardizzone G.D., Belluscio A., Serena F. -

Status and Conservation of Fisheries in the Adriatic
United Nations Environment Programme MEDITERRANEAN ACTION PLAN Regional Activity Centre for Specially Protected Areas STATUS AND CONSERVATION OF FISHERIES IN THE ADRIATIC Draft internal report Draft to be used only to support the preparation of documents for the “Mediterranean Regional Workshop to Facilitate the Description of Ecologically or Biologically Significant Marine Areas. Malaga, Spain, 7-11 April 2014” February 2014 1 Draft internal report not for distribution This report should be quoted as: UNEP-MAP-RAC/SPA. 2014. Status and Conservation of Fisheries in the Adriatic Sea. By H. Farrugio & Alen Soldo. Draft internal report for the purposes of the Mediterranean Regional Workshop to Facilitate the Description of Ecologically or Biologically Significant Marine Areas, Malaga, Spain, 7-11 April 2014. 2 Brief introduction to the Adriatic Sea The Adriatic Sea is a semi-enclosed basin within the larger semi-enclosed sea constituted by the Mediterranean, it extends over 138000 and is characterised by the largest shelf area of the Mediterranean, which extends over the Northern and Central parts where the bottom depth is no more than about 75 and 100 m respectively, with the exception of the Pomo/Jabuka Pit (200-260 m) in the Central Adriatic. The Southern Adriatic has a relatively narrow continental shelf and a marked, steep slope; it reaches the maximum depth of 1223 m. In the Adriatic Sea all types of bottom sediments are found, muddy bottoms are mostly below a depth of 100 m, while in the Central and Northern Adriatic the shallower sea bed is characterized by relict sand. The Eastern and Western coasts are very different; the former is high, rocky and articulated with many islands, the Western coast is flat and alluvial with raised terraces in some areas. -
Impacts of Short-Term Climate Change and Anthropogenic
Impacts of short-term climate change and anthropogenic activity on marine ecosystem variability and biogeochemical processes in the Gulf of Taranto (central Mediterranean Sea) Dissertation with the aim of achieving a doctoral degree at the Faculty of Mathematics, Informatics and Natural Sciences Department of Earth Science Universität Hamburg Submitted by Valerie Menke Hamburg 2017 Datum der Disputation: 02.02.2018 Folgende Gutachter empfehlen die Annahme der Dissertation: Prof. Dr. Gerhard Schmiedl Dr. Uwe Mikolajewicz 2 Abstract This study examines the variability of benthic ecosystems, depositional environments, biogeochemical processes and water mass dynamics on decadal to multi-decadal timescales in the Gulf of Taranto (central Mediterranean Sea). In the Gulf of Taranto, marine processes are closely linked to large-scale and regional climate patterns because precipitation changes in the Po River catchment and related fluctuations in riverine runoff drive changes in marine nutrient and suspended sediment load, local phytoplankton blooms and organic matter availability at the sea floor. This study focuses on the palaoclimatic and palaoecological evolution of the last millennium and further investigates the environmental impacts of short- term periods of cooling and drying events around 4.2 ka and 8.2 ka BP. The aim is to unravel the links between local environmental processes in the Gulf of Taranto and regional to large- scale climate patterns and its variability. The results will be further used to decipher natural and anthropogenic forcing mechanisms. High sedimentation rates in the Gulf of Taranto allow for high-resolution paleoclimate studies, which rely on accurate age models. The location of the Gulf of Taranto, east of the Italian volcanic arc with numerous eruptions documented for the Holocene, suggests the use of tephroanalysis for the age assessment of marine sediment cores.
