Opis:
The killer shrimp Dikerogammarus villosus was recorded for the first time in Lithuanian waters in 2015. The species was detected in three sites in the Curonian Lagoon (on two buoys in the lagoon strait and the harbour, and one littoral sampling site) and in the mouth of the Šventoji River. The species presence in the buoy fouling suggests the involvement of shipping in species introduction. Most likely D. villosus has arrived to the Curonian Lagoon with commercial ships, while the invasion into the mouth of the Šventoji River may be associated with leisure shipping as the port situated therein is not currently functioning. Further northward expansion of the killer shrimp in the Baltic Sea basin seems very probable. As the species is highly aggressive, alterations of local macroinvertebrate assemblages can also be predicted.

Opis:
The present paper reports for the first time on the occurrence of Platorchestia platensis (Krøyer, 1845) (Crustacea, Amphipoda) in Puck Bay (southern Baltic, Poland) in May 2005. A key to the Baltic talitrids is given, which can be used to identify males and females of the four species occurring on Polish shores (Talitrus saltator, Talorchestia deshayesii, Orchestia cavimana, Platorchestia platensis) and additionally Orchestia gammarellus, which may yet be found in the Polish coastal zone.

Can fluctuating asymmetry in Talitrus saltator (Montagu, 1808) (Crustacea, Amphipoda) populations be used as a bioindicator of stress on sandy beach ecosystems?

Opis:
This study focused on verifying the fluctuating asymmetry hypothesis in the crustacean Talitrus saltator, which lives in sandy beaches. We analysed three populations, one from an unpolluted Tuscan beach relatively free of tourism, and two from Sicilian beaches, which have been increasingly used for tourism and have been exposed to hydrocarbon/pesticide pollution. Results confirmed the sexual dimorphism in the second antennae flagella, which in the Tuscan population presented directional asymmetry. This population had a significant level of fluctuating asymmetry in the P6 and P3 meri. The results showed the importance of the developmental stage during which environmental mechanical stresses act.

Opis:
This paper describes the current species composition of the genus Gammarus in Puck Bay (western Gulf of Gdańsk, Poland).Sa mples were taken at 9 shallow (ca 0.4 m deep) and 4 deeper (ca 10 m) stations from April 1997 to March 1998. Six Gammarus species were recorded. Gammarus salinus was the most numerous, making up 34.95% of the total of identified amphipod specimens. This species was common throughout the bay but rarely predominant. G. zaddachi (34.75%) was dominant in the northern part of the bay from January to April and was found in almost 2/3 of samples.Less numerous were G. oceanicus (19.15%), common in the southern and eastern parts of Puck Bay, and G. duebeni (9.85%), prevalent in shallow and rocky locations. G. inequicauda and G. locusta made up only 1.13% and 0.12% of the total amphipod material respectively. The species composition of the genus varied considerably not only from one sampling locality to another but also from season to season.I t is possible that two species (G. locusta and G. inequicauda) are currently withdrawing from Puck Bay.
