The non-indigenous tetraodontid of Indo-Pacific origin Tylerius spinosissimus is recorded for the first time in Turkish waters and for the third time in the Mediterranean Sea. This record increases to 53 the number of Indo-Pacific alien fish species present along the coasts of Turkey.

COLLECTIVE ARTICLE A

This Collective Article presents information on 37 taxa belonging to 6 Phyla and extending from the western Mediterranean to the Levantine Sea. The new records were found in 10 countries as follows: Algeria: first reports on the presence of the fish species Lesueurigobius sanzi, L. friesii, L. suerii and Luvarus imperiali; France: first record of the alien nudibranch Godiva quadricolor; Italy: first record of an adult-sized red emperor snapper Lutjanus sebae from the southern Tyrrhenian Sea; first record of the pantropical rhodophyte Chondria curvilineata and the Lessepsian fish Siganus luridus from southern Sicily; record of a large pregnant female Dusky shark Carcharhinus obscurus off Sicily; Albania: first record of the fish Ruvettus pretiosus, new records of the alien molluscs Conomurex persicus, Bursatella leachii, Dendostrea cf. folium, Fulvia fragilis and Ruditapes philippinarum and additional report of the alien bivalve Pinctada imbricata radiata; Montenegro: first record of the sea slug Thecacera pennigera in the Adriatic Sea; Greece: first record of the invasive calcarean sponge Paraleucilla magna in Greek waters; occupancy estimation of the established cryptogenic rhodophyte Ganonema farinosum, the alien crustacean Percnon gibbesi and the alien fish species Fistularia commersonii, Siganus luridus, and S. rivulatus along the Cretan coastline; first record of the alien mollusc Sticteulima lentiginosa in Greek waters suggesting a westward unintentional expansion of this species; Turkey: photographic evidence of interactions of the monk seal Monachus monachus with sea-cage farms in the Turkish Aegean Sea and first record of the yellow boxfish Ostracion cubicus in the Turkish Mediterranean; Cyprus: first records of the rare speleophilic fish Thorogobius ephippiatus and Grammonus ater in Cyprus, extending the known distribution of the latter Mediterranean endemic species eastwards; first records of the alien fish Kyphosus vaigiensis and the alien crustacean species Macrophthalmus indicus and Carupa tenuipes as well as additional records of the alien echinoderm Diadema setosum and the alien ascidian Symplegma brakenhielmi in the country; Lebanon: first report on the presence of the four alien fish species Cephalopholis taeniops, Equulites popei, Pseudupeneus prayensis and Sphoeroides pachygaster; Egypt: first record of the Lessepsian fish Synchiropus sechellensis in the Egyptian Mediterranean waters.

On the 14th of June, 2005, in the Danube side channel "Jojkic" (N 44?50'33.1??, E 20?27'46.1??) near Belgrade, we recorded the presence of A. melas, ranging in weight (W) from 11.2 g to 135.6 g, and standard length (Ls) from 70 mm to 173 mm. Specimens were obtained from professional fishermen, who caught them with gill nets, as well from sport fishermen using fishing roads. Also, on 28th of May, 2005, on the lake "Savsko jezero" (N 44?47'20.1??, E 20?24'54.6??), we collected two specimens with gill nets. They were held in an aquarium until the 20th of June, when they were analyzed. Their weight (W) was 48.8 g and 97.5 g, their standard length (Ls) 145 mm and 183 mm, respectively.

River pollution has been a major problem in Malaysia and significantly affects the environment. One of the contributing issues would be the spread of invasive alien fish species that has given negative impacts on the environment and ecological disaster, the human health, harming the native animals and plants, as well the economy. Based on the National Committee on Invasive Alien Species Report in 2018, that 46 invasive alien species from a total of 130 species in the established main invasive alien species lists in Malaysia.  The alien fishes have been known to make their presence in our dams, lakes and rivers but not much attention has been paid to their existence. Based on these facts, it is proven that the issue poses a significant risk hence an urgent attention is required in managing this pollution through proactive legal measures to enforce strictly the existing law so as to prevent the halt of the spread of invasive species. A legal doctrinal and non-doctrinal modes of research are used to examine and review on the existing laws and/or policy governing this issue. This research will help to provide reference and strategic planning via legal approach for better controlling the invasion in our Malaysian waters.

Glochidia (parasitic larvae) of freshwater mussels generally require a fish as a host. Westralunio carteri Iredale, 1934 (Bivalvia : Hyriidae), the only freshwater mussel found in south-western Australia, was listed as Vulnerable, but recently changed to Least Concern (International Union for the Conservation of Nature). Glochidia were found on four alien and seven native species of fish from 18 sites in the South West Coast Drainage Division. On alien fishes, prevalence of glochidia ranged from 0.0 to 41.0% and mean intensity (number of glochidia per infested fish) from 1.0 to 6.0, while on native fishes prevalence was 9.2–90.5% and intensity was 2.3–7.1. Glochidia infestation was greatest on benthic fishes, which may be a consequence of greater encounter rates, but other factors, such as host size, probably also influence glochidia prevalence and intensity. Glochidia were generally restricted to fins of infested fish, and were rarely on gills or the body surface. In the laboratory, four native and one alien fish species were found to be competent hosts for their ability to produce juvenile W. carteri, but two alien fish species were not. The inability of some alien fishes to produce juvenile W. carteri could potentially reduce recruitment success in areas dominated by alien fishes.
