This Collective Article presents information on 22 species belonging to 5 Phyla, arranged geographically from west east. The new records were found in 8 countries as follows: Spain: first record of the two scarcely known nemerteans Baseodiscus delineatus and Notospermus geniculatus Formentera; Malta: second alien fish Lagocephalus sceleratus; Italy: polychaete Syllis pectinans isopod Paranthura japonica, well cryptogenic opisthobranch Anteaeolidiella lurana, fouling assemblages along docks...
In the present Collective Article information on 26 taxa belonging to 8 Phyla and extended from western Mediterranean Levantine Sea are presented. The new records were found in 9 countries as follows: Spain: first record for of crab Cancer bellianus; Algeria: further alien fish Lagocephalus sceleratus west Algerian waters; Italy: report presence establishment ctenophore Mnemiopsis leidyi Lessina Varano Lagoons (W. Adriatic) Penaeus aztecus Corigliano Gulf (Italian Ionian). Moreover,...
The Collective Article ‘New Mediterranean Biodiversity Records’ of the Marine Science journal offers means to publish biodiversity records in Sea. current article is divided two parts, for native and alien species respectively. new fish include: slender sunfish Ranzania laevis scalloped ribbonfish Zu cristatus Calabria; Azores rockling Gaidropsarus granti Calabria Sicily; agujon needlefish Tylosurus acus imperialis Northern Aegean; amphibious behaviour Gouania willdenowi Southern Turkey.

The present work deals for the first time with species diversity of gillnets operated on fisheries coasts Alexandria City from El-Montazah to Sidi Kirayr. A total 6161 specimens about 427 kg were collected during periods Feb 2018 Jun and Dec 2019 Nov 2020 using two types gillnets: demersal pelagic gillnets. All samples identified photographed. 108 in catch (99 fish species; 1 molluscan 8 crustacean species). From that, 28 lessepsian recognized. was dominated by Family Sparidae (25 species)...
The present study aimed to analyze the non-target catch in Egyptian Mediterranean waters, off Port Said, during period from spring 2017 winter 2018. analysis revealed that 75 species, fish constituted about 69.4% of total weight, whereas invertebrates reached 30.6%. For fish, 51 fishes were identified (50 bony and one elasmobranch), which 17 lessepsian species found. high percentage (82.67%) was with an average length between 4.0 <9.0 cm. highly represented by numbers were: Engraulis...
In the present study, catch of beach seine operating in Eastern Harbor Alexandria (Egypt) during fishing season 2009 was investigated. Fishing is allowed all year except for some weeks winter. Catch efficiency estimated to be 37.94 kg/haul and rate 25.29 kg/h. The classified into economic (60.24%) non-economic (39.76%) species. total number species caught 46 (31 economic, 15 non-economic) belonging 31 families (16 non-economic). category dominated by immigrant sardine Herklotsichthys...
Catch and effort (CPUE) of the purse-seine using light, age growth lessepsian fish "Etrumeus teres" from Egyptian Mediterranean waters were studied in period 2008. It was found that, average annual catch 1.7 (ton/boat/night). The diversity composed seventeen different species. Clupeids dominant 74.1% total catch. Seven species involved constituted 41.18% 19.01% number weight catch, respectively. Round herring E. teres highest one these immigrants, accounting for 10.93% catch; it exhibited...
The present study is focused on investigating the fisheries of pelagic fish caught by purse seiners using light from Alexandria to Rosetta during 2007. Five experimental fishing operations were processed seasonally (spring, summerand autumn).The operation and sampling explained. Analysis species composition (seasonal total) size carried out. A comparison between other previous studies was done.The average catch net per night maximum summer (1295 Kg),while minimum one autumn (479 Kg). most...
This article firstly records Pseudotolithus senegallus (Cuvier, 1830) species in the Mediterranean Sea. juvenile specimen of with total length 15.5 cm and weight 37 g, was obtained by experimental bottom trawling using commercial trawler (stretched mesh size: 15 mm; duration time: four hours; location: east Suez Canal main stream Mediterranean, off Port Said). Opercle lining jet black, showing through a dark blotch externally. Axils pectoral-fin base dark, distal portion caudal fin darkish...
