This article firstly records Pseudotolithus senegallus (Cuvier, 1830) species in the Mediterranean Sea. juvenile specimen of Pseudotolithus senegallus (Cuvier, 1830) with total length 15.5 cm and total weight 37 g, was obtained by experimental  bottom trawling using  commercial bottom trawler (stretched mesh size: 15 mm; duration time: four hours; location: east of Suez Canal main stream in the Mediterranean, off Port Said). Opercle lining jet black, showing through a dark blotch externally. Axils of pectoral-fin base dark, distal portion of caudal fin darkish whereas anal and pelvic fins are yellowish. Gas bladder with a pair of arborescent appendages, dividing into short anterior branches and a dozen or so long tubular posterior appendages along sides of bladder beyond its tip. I suggest the method of introduction to the Mediterranean waters is ballast water of ships as it is recorded only from Mauritania to Angola on the western coast of Africa.

Habitat of the family Priacanthidae is tropical and subtropical Atlantic, Indian, and Pacific oceans. The features of the  family members are generally very big eyes, deep bodies, upturned mouth,  and generally reddish color. In the this paper, we report the presence of an arrow bulleye P. sagittarius in coast of Turkey waters in the Mediterranean Sea. On the 27th December, 2017, a single specimen of P. sagittarius was collected by Mr. Hüseyin Çınar, captain of the commercial bottom trawler Furkan Reis vessel, off the Taşucu, Mersin (36°07'2.82"N 33°51'6.42"E) Turkey coasts. The specimen of P. sagittarius was collected at a depth of approximatetly 100 m by a bottom trawl net; the mesh size of 22mm. The collected specimen of arrow bulleye P. sagittarius was 255 mm total length (TL) and 307 g total weight (TW). The finding of the present study is the first record of specimen along shores of the Mediterranean of Turkey. This record suggests that this species is spread towards to west along in the Mediterranean.

AbstractStock overexploitation, bycatch, discards and gear impacts on the environment are outstanding issues for Mediterranean fisheries. The adoption of alternative fishing gears is an appealing solution to ensure a more sustainable exploitation of resources. We discuss the pros and cons of pots as alternative gears by reviewing their main designs, spatial distribution and target species in the Mediterranean basin. We assessed the technical factors affecting the catch efficiency of the different pot designs for four target species: spiny lobster, Palinurus elephas; Norway lobster, Nephrops norvegicus; common octopus, Octopus vulgaris and pandalid shrimps, Plesionika spp. We found that pot volume is important to catch Octopus; mesh size to catch Nephrops and Plesionika; entrance surface to catch Octopus, Nephrops and Plesionika; pot shape/colour and entrance shape/position to catch Octopus and Plesionika; and bait type to catch Octopus and Nephrops. The literature review shows that pot fisheries have several considerable advantages over conventional gears, especially in terms of discards, bycatch, seabed impacts (particularly compared with bottom trawls and passive set nets), size and species selectivity, gear depredation, catch quality and gear cost, besides saving time and labour. Disadvantages hampering their wider diffusion include ghost fishing, a low catch of finfish species, the narrow range of species targeted by each pot design and the current early stage of research. These data make a clear case for using pots as alternative gears to traditional ones in the Mediterranean Sea in some areas and seasons to catch certain target species.

The capture of five specimens of Solea (Microchirus) boscanion (Osteichthyes: Soleidae), a species previously unrecorded in the Mediterranean, is reported from the Iberian coast (western Mediterranean). The main morphometric and meristic measurements of this species with data of the other sympatric, and morphologically very similar, soleids Microchirus variegatus and Buglossidium luteum are also given. The record is discussed in relation to climate change and competition between species.

Morphological Differences

This study provides the first report of the presence of Coolia malayensis in the Mediterranean Sea, co-occurring with C. monotis. Isolated strains from the Gulf of Gabès, Tunisia (South-eastern Mediterranean) were identified by morphological characterization and phylogenetic analysis. Examination by light and scanning electron microscopy revealed no significant morphological differences between the Tunisian isolates and other geographically distant strains of C. monotis and C. malayensis. Phylogenetic trees based on ITS1-5.8S-ITS2 and D1‒D3/28S rDNA sequences showed that C. monotis strains clustered with others from the Mediterranean and Atlantic whereas the C. malayensis isolate branched with isolates from the Pacific and the Atlantic, therefore revealing no geographical trend among C. monotis and C. malayensis populations. Ultrastructural analyses by transmission electron microscopy revealed the presence of numerous vesicles containing spirally coiled fibers in both C. malayensis and C. monotis cells, which we speculate to be involved in mucus production.

Ophelia roscoffensis Augener, 1910 is an opheliid worm identifiable by the number of anterior abranchiate chaetigers and the number of the gill pairs. Although it was already reported in the Mediterranean Sea, it has never been found in the Italian waters. This study represents the first record of Ophelia roscoffensis in the Italian waters. A total of 18 specimens were collected along the coast of Civitavecchia (Tyrrhenian Sea) in a Posidonia oceanica (L.) Delile bed at a depth of 7 m.

Microlipophrys adriaticus (Steindachner & Kolombatovic, 1883) is an endemic blenny of the Mediterranean Sea. It is also known from the Sea of Marmara and the Black Sea. However, unlike other species of combtooth blennies, M. adriaticus is a fish with a limited distribution in Adriatic Sea, especially in the north, where it can be common. We report here the first record of this species from the waters of the Ionian Sea.
