This paper discusses the first record of the sammara squirrelfish, Neoniphon sammara in the Egyptian Mediterranean waters.
On April 2020, 17 specimens of this species were recorded in the miscellaneous catch at the Mersa Matruh landing site on the
Mediterranean Sea (31.33333° Ν, 27.216665° E), Egypt. The collected specimens represent the first reco...

... Egyptian Mediterranean coast is about 1100 km extending from El-Sallum in the West to El-Arish in the East. Mersa Matruh is 240 km west of Alexandria and 222 km east of Sallum, the last point on the EgyptianLibyan border (31.33333° Ν, 27.216665° E) ( Fig. 1). It is considered an unexploited fishing ground due to its rocky bottom, with an annual average yield of 350 ...

... HL was 2.83 in SL, the BD was 3.40 in SL, the ED was 1.5 in SL, and the ED was 2.76 in HL. The dorsal fin spines were XI, whereas the soft rays were 13; the anal fin spines were IV plus eight soft rays; the pelvic fin spines were one plus seven soft rays; the lateral line had 41 large rough and ctenoid scales ( Fig. 2; Table ...

... first Holocentrid species that migrated and was established in Mediterranean from long time was Sargocentron rubrum (Forsskål, 1775), which entered the Mediterranean Sea via the Suez Canal (Golani & Ben-Tuvia, 1985). Until 2020, S. rubrum was considered the only representative of the squirrelfish in the Mediterranean Sea (Haas & Steinitz, 1947, Štirn, 1970, Ibrahim & Soli- man, 1996). ...

Viral nervous necrosis is a viral disease caused by betanodavirus causing deaths and epidemics in wild or farmed sea fish, especially in juveniles. Betanodavirus has been detected in farmed European seabass and gilthead seabream in Turkey. However, there are no studies on the presence of betanodavirus in wildlife along the Turkish Mediterranean coast. This study aimed to investigate the presence of betanodavirus in wild fish along the Turkish coast of the Mediterranean and to characterize isolates using molecular tools. Hence, 400 fish belonging to 27 different wild species were caught and tested using real-time RT‒PCR. The betanodavirus genome was detected in red mullets (25/50) and garfish (2/4) and identified as RGNNV and RGNNV/SJNNV genotype, respectively according to partial genome sequencing of the RNA1 and RNA2 segments. Phylogenetic analysis showed that isolated viruses were similar to isolates collected from other parts of the Mediterranean Sea and China, India, and Japan. The results of the studies show that different genotypes are circulating in the studied region in different species. These findings indicates that more research on wildlife, both around the farm and in other regions, are needed to prevent spreading of the virus to aquaculture facilities.
In the present study, one juvenile specimen of redcoat Sargocentron rubrum (Forsskål, 1775) was first reported from the Mediterranean coast of Turkey with a visual record during an underwater survey conducted from the coast of Arsuz (Konacik), Iskenderun Bay, at a depth of 3 m, on September 11, 2018. The Family Holocentridae is currently represented in the Mediterranean by seven species, all exotic, six of them originate in the Red Sea (Lessepsian migrants) and one originates from the Atlantic.
