The Network was established by the Angel Shark Project, International Union for the Conservation of Nature (IUCN) Species Survival Commission Shark Specialist Group, Shark Trust, and Submon to facilitate dialogue and information sharing on angel shark conservation efforts, in particular across the range ofSquatina aculeata, S. oculata, and S. squatina. It has since expanded to include additional collaborators. The success of the Eastern Atlantic and Mediterranean Angel Shark Conservation Strategy and associated Action Plans (such as this) requires cooperation between different stakeholders, working together towards a common vision. All interested parties are invited to join the network to receive updates and help to deliver the objectives laid out in the Strategy and associated Action Plans – visit www.angelsharknetwork.com.

BOX; 1408, Lattakia, Syria [email protected] (corresponding author); [email protected]; [email protected]; [email protected]; [email protected] ABSTRACT Syria’s total marine fisheries catches were estimated for the 1950-2010 time period using a reconstruction approach which accounted for all fisheries removals, including unreported commercial landings, discards, and recreational and subsistence catches. All unreported estimates were added to the official data, as reported by the Syrian Arab Republic to the United Nation’s Food and Agriculture Organization (FAO). Total reconstructed catch for 1950-2010 was around 170,000 t, which is 78% more than the amount reported by Syria to the FAO as their national catch. The unreported components added over 74,000 t of unreported catches, of which 38,600 t were artisanal landings, 16,000 t industrial landings, over 4,000 t recreational catches, 3,000 t subsistence catches and around 12,000 t were discards.

  • Florida's Fintastic Sharks and Rays Lesson and Activity Packet
    Florida's Fintastic Sharks and Rays An at-home lesson for grades 3-5 Produced by: This educational workbook was produced through the support of the Indian River Lagoon National Estuary Program. 1 What are sharks and rays? Believe it or not, they’re a type of fish! When you think “fish,” you probably picture a trout or tuna, but fishes come in all shapes and sizes. All fishes share the following key characteristics that classify them into this group: Fishes have the simplest of vertebrate hearts with only two chambers- one atrium and one ventricle. The spine in a fish runs down the middle of its back just like ours, making fish vertebrates. All fishes have skeletons, but not all fish skeletons are made out of bones. Some fishes have skeletons made out of cartilage, just like your nose and ears. Fishes are cold-blooded. Cold-blooded animals use their environment to warm up or cool down. Fins help fish swim. Fins come in pairs, like pectoral and pelvic fins or are singular, like caudal or anal fins. Later in this packet, we will look at the different types of fins that fishes have and some of the unique ways they are used. 2 Placoid Ctenoid Ganoid Cycloid Hard protective scales cover the skin of many fish species. Scales can act as “fingerprints” to help identify some fish species. There are several different scale types found in bony fishes, including cycloid (round), ganoid (rectangular or diamond), and ctenoid (scalloped). Cartilaginous fishes have dermal denticles (Placoid) that resemble tiny teeth on their skin.

The specimen was 174 cm long (total length) and weighed approximately 35 kg. The recent single capture of S. squatina in the southeastern Sea of Marmara confi rms the contemporary presence of the species in this land- locked small marine region; however, the paucity of the species in the fi shing records of Marmaric fi shes since 2000, confi rms its rarity in the studied marine area. Keywords: Angelshark, Squatina squatina, Sea of Marmara, status, endangered, protection STATO DELL’ANGELO DI MARE, SQUATINA SQUATINA (ELASMOBRANCHII: SQUATINIFORMES: SQUATINIDAE), NEL MARE DI MARMARA SINTESI Il 4 gennaio 2014, una femmina di Squatina squatina è rimasta impigliata in una rete tramaglio, ad una profondità di circa 50 metri. La lunghezza totale dell’esemplare era pari a 174 cm per circa 35 kg di peso. La recente singola cattura di S. squatina nella parte sud-orientale del mare di Marmara conferma la presenza temporanea della specie in questa piccola semichiusa regione marina. Tuttavia, la scarsità di segnalazioni della specie nei registri di cattura della fauna ittica del mare di Marmara dal 2000, conferma la sua rarità nell’area marina studiata.

Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

  • Angelshark (Squatina Squatina)
    12th Meeting of the Conference of the Parties (CoP12) to the Convention on Migratory Species (CMS) Angelshark (Squatina squatina) Proposed action: Inclusion on CMS Appendices I and II Proponent: Monaco Overview Shark species around the world face a wide variety of threats, including being caught as bycatch. The overexploitation of the Angelshark, Squatina squatina for its meat, skin, and liver has made studying the species very difficult. The species’ seasonal north-south and onshore-offshore migrations are poorly documented largely because of the species’ scarcity. The available data shows the population decrease has caused some local or regional extinctions over most of its range, resulting in Squatina squatina being listed as Critically Endangered on the IUCN Red List. The decrease is largely due to targeted fisheries and, more recently, being caught incidentally as bycatch. The species is only adequately protected in some parts of its range and enforcement is lacking, which is why it is necessary to list the species on Appendices I and II. 12th Meeting of the Conference of the Parties (CoP12) to the Convention on Migratory Species (CMS) Biology and Distribution range is subject to intense demersal fisheries. This species is highly vulnerable from birth onwards to bycatch in the Squatina squatina is nocturnal, swimming at night and benthic trawls, set nets and bottom longlines which usually lying buried in sediment by day with only its eyes operate through most of its range and habitat. and dorsal fins protruding. It is an ambush predator that feeds primarily on bony fishes, cephalopods, skates, Uses crustaceans and mollusks. The species is a high level trophic predator.

Nat. Croat., Vol. 26, No. 2, 313-320, 2017, Zagreb. Two out of three critically endangered species of angelsharks (genus Squatina (Dumeril, 1806)) in- habiting the Mediterranean have been recorded in the Adriatic Sea, namely smoothback angelshark S. oculata Bonaparte, 1840 and common angelshark S. squatina (Linnaeus, 1758). While S. oculata has been extirpated from the Adriatic Sea due to overfishing, the presence of S. squatina remained questionable and some authors propose the species is regionally extinct since the 1980s. We present new data on the occurrence of S. squatina in the Croatian Adriatic Sea based upon inspection of collections from natural history museums and literature sources as well as three new records resulting from bycatch in com- mercial bottom trawls in 2016 and 2017.
