With the present study, P. lineatus is the first time reported from Turkish marine waters, in the Iskenderun Bay, the Northeastern Mediterranean and also this is the first Plotosid species recorded from Turkish Seas.
Scopthalmus rhombus is rarely occurred and restricted to marine and estuarine sites in the eastern Marmara Sea and western Black Sea coast of Turkey. S. rhombus is occasionally caught in low numbers and continuously decreased in abundance due to overfishing and habitat degradations. This species should be considered to be threatened for Turkish marine waters. This species might also be recorded in the IUCN Red List of Threatened Species as Near Threatened (NT).
On 15 March 2015, a single specimen of Parupeneus forsskali (Fourmanoir & Guézé, 1976) was captured by a trammel net at a depth of 30 m from Iskenderun Bay. The occurrence of the Red Sea goatfish P. forsskali was reported for the first time in the Iskenderun Bay and the first captured data for the Turkish marine waters.

The total sequence length, variable sites and parsimony informative sites were 868 bp, 12 bp and 7 bp from 222 individuals, respectively. The nucleotide frequencies were 32.55% A, 31.32% T, 14.44% C, and 21.68% G. The total number of haplotypes was 19, and the highest number of different haplotypes was observed in the nortestern Mediterranean (the Iskenderun Bay) sample, and the lowest was observed in the Bulgarian sample. Low genetic diversity was observed within populations, and the mean genetic diversity within populations and the mean genetic divergence between populations were 0.0009 and 0.0013, respectively. In the statistical analysis, S. sarda was divided into three genetically different populations (P<0.001); the Black and Marmara Sea populations comprise one genetic unit, and the Aegean and Mediterranean coast of Turkey populations constitute the genetically different second unit. The Adriatic Sea population from Croatian coast was also genetically different from these two units. The neighbor joining tree revealed three main phylogenetic nodes; in the first node, the Black Sea, Bosphorus and Marmara Sea samples were grouped close together. In the second main node; the Aegean and northeastern Mediterranean Seas samples were clustered close to each other, and the Adriatic Sea sample was far from these samples, but closer to the Aegean and northeastern Mediterranean samples than the Black Sea and Marmara Sea samples.

Four specimens of A. lunaris were captured in Iskenderun Bay, Northeastern Mediterranean coast of Turkey at depth about 17m by gill net on 18 August 2015. The moon crab is the first non-native crab from the family Matutidae established in the Turkish coast.

Only five microsatellite loci were successfully amplified with new developed PCR conditions and used for routine analysis of stock identification of S. sarda.

Otolith chemistry analyses showed high differentiation of turbot stocks, revealing a clear discreteness of the Black Sea (Duzce and Trabzon) and Marmarasamples, indicating limited gene flow between the regions. Univariate analysis of variance showed significant differences between means of all the samples for all otolith elements (Ba, Mg, Mn, Sr, Na, K and Ca) (P<0.001). The contribution of each element in distinguishing between the populations for the first discriminant functions revealed high contribution from the elements Sr, Mg, Mn and Na in the discriminant analysis. Overall assignment of individuals into their original sample was % 100. There was highly positive
correlation in the otolith elements concentration between Ca and Ba, Mg and Ba; and negative correlations between Na and Sr, Mn and Sr.
