First record of the Japanese shore crab Hemigrapsus sanguineus (de Haan, 1835) (Brachyura: Grapsoidea: Varunidae) from the Black Sea
(pp S1-S4)
|
|
The Japanese shore crab Hemigrapsus sanguineus is recorded for the first time from a Black
Sea locality: Tomis Marina in Constanţa, Romania. The suggested vector of introduction is as
adults in the hull fouling of yachts. The species has not established and salinity requirements
for larval development make it unlikely that it will ever establish in the Black Sea.

First record of Pontogammarus robustoides Sars, 1894 (Crustacea: Amphipoda) in the Gulf of Riga (Baltic Sea)
(pp S5-S7)
|
|
The paper presents the first record of the Ponto-Caspian amphipod crustacean Pontogammarus robustoides G.O. Sars, 1894,
in the Gulf of Riga, Baltic Sea. Eight individuals of this invasive amphipod were found in June 2009, in shallow
waters of the gulf near Yurmala city. Most likely this species entered the Gulf of Riga from Latvian rivers
emptying into the Baltic Sea, where it was previously found. However, introduction via ships coming from either
southern or north-eastern parts of the Baltic Sea is also a possibility.

Non-native, invasive red lionfish [Pterois volitans (Linnaeus, 1758): Scorpaenidae], is first recorded in the southern Gulf of Mexico, off the northern Yucatan Peninsula, Mexico
(pp S9-S12)
|
|
We recorded the first sighting and collection of the non-native, invasive red lionfish
[Pterois volitans (Linnaeus, 1758): Scorpaenidae] in the southern Gulf of Mexico, off the northern
Yucatan Peninsula. In December 2009, two individuals were sighted (one of them speared) at 38 m depth over
a reef formation, about 58 km northwest of the Alacranes Reef National Park, which is located 130 km off
the northern coast of the Yucatan Peninsula, Mexico. More than 20 years after the introduction of
P. volitans into the western Atlantic, specifically off the Florida and North Carolina coasts,
the invasion circuit now appears to be closing in, since this new record was made about 800 km from
the Dry Tortugas and Marquesas, Florida. This recording appears to be the first introgression of
the P. volitans population into the Gulf of Mexico via larval transport.

First record of the non-native three spot gourami, Trichogaster trichopterus (Pallas, 1770) (Teleostei: Osphronemidae) in Jamaica
(pp S13-S16)
|
|
Five specimens of the non-native three spot gourami (Osphronemidae: Trichogaster trichopterus)
were collected from a small pond near the northern coast of Jamaica in June 2009. The collection
represents the first documentation of this species in Jamaica. Origin of the introduction is not known.
Herein, we discuss the occurrence of this species in Jamaica and possible threats posed to the island’s
native fish fauna.

New records of Corbicula fluminea (Müller, 1774) in Galicia (Northwest of the Iberian Peninsula): Mero, Sil and Deva rivers
(pp S17-S20)
|
|
This paper presents new records of Asian clam Corbicula fluminea in the rivers Mero, Sil and Deva.
Records from the Rivers Sil and Deva showed the increase of its spread in the Miño river basin.
Findings in the Mero basin represented the first Iberian record of this species outside the Miño basin.
Furthermore, it was the most north-western record in the Iberian Peninsula.

The slipper limpet Crepidula fornicata Linnaeus, 1758 becomes established in Ireland
(pp S21-S25)
|
|
Chains and solitary individuals of the slipper limpet Crepidula fornicata were found,
some with egg capsules, at several localities within Belfast Lough on the north-east coast
of Ireland during 2009. The species is widely dispersed, being found on the lower shore to depths
of 7 m attached to scallops, mussels and stones and so is considered to be established.
Shell winter growth checks indicated a possible arrival in or before 2004.
While there have been previous records of this invasive species in Ireland, this is the only known
established population.

Establishment of the angular crab Goneplax rhomboides (Linnaeus, 1758) (Crustacea, Decapoda, Brachyura) in the southern North Sea
(pp S27-S30)
|
|
So far the angular crab Goneplax rhomboides (Linnaeus, 1758) was mostly a northeastern
Atlantic and Mediterranean species and was quite rare in the North Sea where no evidence
for sustainable populations existed. In 2008 and 2009 a total of 82 individuals of
Goneplax rhomboides (Linnaeus, 1758) were found at 22 widespread locations
in the southern North Sea indicating that this species is now well established in the area.

Katamysis warpachowskyi Sars, 1877 (Crustacea, Mysida) invaded Lake Constance
(pp S31-S34)
|
|
The mysid Katamysis warpachowskyi Sars, 1877 originated in the Ponto-Caspian region
and the associated river systems. The first evidence of its transgression of the limits
of the watersheds of its natural Ponto-Caspian origin was found when three individuals
were recorded in October 2009 in eastern Lake Constance (Austria). In March 2010,
K. warpachowskyi comprised 10% of the mysid assemblage and was mainly found
in rocky habitats. On both sampling dates, breeding females were present. Before this invasion,
Limnomysis benedeni Czerniavsky, 1882, was the only mysid in Lake Constance and is also
distributed in the Rhine river system. Since the two mysids coexist in Lake Constance,
K. warpachowskyi will likely become established in the lake and further expand into
the main part of the Rhine. K. warpachowskyi is known as a benthic organism and feeds
on detritus and small algae; therefore, the impact on the lake ecosystem should be weaker than
that of pelagic mysids.

New records of Corbicula clams in French rivers
(pp S35-S39)
|
|
The aim of this paper is to present new data and review the current distribution of
Corbicula spp. in France. Three morphotypes were recorded during the study - “round form”,
“light R form” and “saddle form”. During April 2009, Corbicula spp. were found in several
watercourses in France, including three rivers (Canal de la Somme, Oise and Vilaine) where
the taxa were not previously reported. In addition, this is the first report of form S in
the River Seine and, the first record of the “light R form” in the River Gard. Molluscs
of the genus Corbicula are considered to be a well established alien species in
large rivers.

First record of the Emperor angelfish, Pomacanthus imperator (Teleostei:
Pomacanthidae) and the second record of the spotbase burrfish Cyclichthys spilostylus
(Teleostei: Diodontidae) in the Mediterranean
(pp S41-S43)
|
|
The Emperor angelfish Pomacanthus imperator (Bloch, 1787) was recorded for the first
time from the Mediterranean. Its occurrence there is due to either migration from the Red Sea
(Lessepsian migration) or as an escapee from the aquarium trade. The spotbase burrfish
Cyclichthys spilostylus (Leis and Randall, 1982) was recorded for the second time
in the Mediterranean, almost two decades after the first record.

First record of the Indo-Pacific arrow bulleye Priacanthus sagittarius Starnes, 1988
in the Mediterranean Sea
(pp S45-S47)
|
|
A single specimen of Priacanthus sagittarius was captured by a commercial trawler
off the Mediterranean coast of Israel on 28th November 2009. This is the first record
of the species, and possibly the first alien member of the Priacanthidae from the Mediterranean Sea.

A ‘flood’ of alien cardinal fishes in the eastern Mediterranean - first record
of the Indo-Pacific Cheilodipterus novemstriatus (Rüppell, 1838) in the Mediterranean Sea
(pp S49-S51)
|
|
Four alien species of Red Sea Cardinal fishes have been reported to date from the eastern Mediterranean,
three of them discovered during the last five years. Here we report the finding of a fifth alien cardinal
fish Cheilodipterus novemstriatus (Rüppell, 1838) in the eastern Mediterranean Sea. The fish was
collected from the wreck of an old sunken ship off the Tel Aviv coast.

Presence of the invasive red lionfish, Pterois volitans (Linnaeus, 1758),
on the coast of Venezuela, southeastern Caribbean Sea
(pp S53-S59)
|
|
We report the presence of the invasive Indo-Pacific red lionfish (Pterois volitans) in 23 localities
of the Venezuelan coast, southeastern Caribbean Sea. This finding is based on ten specimens collected
at Parque Nacional Archipiélago de Los Roques (PNAR, Dependencias Federales), Playa Cal, Caraballeda
and Puerto Carayaca (Estado Vargas) and 30 specimens observed in 18 localities of PNAR, Parque Nacional
Morrocoy (Estado Falcón), Bahía de Cata, Ensenada de Cepe (Estado Aragua), Puerto Cruz, Chichiriviche
de La Costa, Mamo, Catia La Mar, La Guaira, Macuto, Caraballeda (Estado Vargas) and Farallón Centinela
(Dependencias Federales). The specimens were collected and observed from November 2009 to June 2010.
This is the first published report documenting their occurrence in Venezuela.

The River Odra estuary – another Baltic Sea area colonized by the round goby Neogobius melanostomus
Pallas, 1811
(pp S61-S65)
|
|
The round goby (Neogobius melanostomus Pallas, 1811) has been present, since the 1990s,
in the Gulf of Gdańsk where it forms a strong population and where the species is locally the most
important fish in shallow inshore areas. No similarly large, independent round goby population in
the Baltic Sea area has been found beyond the Gulf of Gdańsk and the adjacent Vistula Lagoon.
As shown by the research carried out in 2009, the round goby is abundant also in the River Odra estuary,
which may provide evidence of the presence of a local, reproducing population.

First record of Asian clam Corbicula fluminea (Müller, 1774) in the Republic of Moldova
(pp S67-S70)
|
|
Living individuals of Asian clam Corbicula fluminea (Müller, 1774) (Bivalvia: Veneroida: Sphaeriacea:
Corbiculidae) have been recorded for the first time in the Republic of Moldova (Prut River basin,
November 2009). Perhaps, this invasive species entered the Prut River basin from the Romanian or
Ukrainian territories, where this species was previously recorded. This invasive species may negatively
influence the native bivalves as they are in competition for both nutrient resources and substrate.

Hemimysis anomala is established in the Shannon River Basin District in Ireland
(pp S71-S78)
|
|
The Ponto-Caspian mysid shrimp Hemimysis anomala was found in Ireland for the first time in April 2008.
During 2009 it was found throughout most of the Shannon River Navigation (~250km) occurring in swarms
at estimated densities of ~6 per litre in shallows and in lower densities at depths of ~20m where its
distribution overlaps with the native Mysis salemaai. Broods were found from March to September.
It occurs mainly in lakes but small numbers were found at one river site. In summer, shallow-water specimens
were found only during the night but in winter could be captured in daytime. It is not known by what means
the species arrived in Ireland, or when.

First record of Phyllorhiza punctata von Lendenfeld, 1884 (Cnidaria: Scyphozoa, Mastigiidae) in Mexico
(pp S79-S84)
|
|
The Australian spot jellyfish Phyllorhiza punctata has not been recorded previously for any coast
of Mexico. A giant jellyfish was recorded for the first time in June 2006 in Laguna de Mandinga,
southwestern Gulf of Mexico. Between 2007 and 2008, another three adult specimens were collected
and later in May 2009 and April-June 2010 a great number of juveniles and adults were observed,
of which 142 were collected. The presence of juveniles and adults throughout five consecutive
years indicates that the species has a seasonal pattern. It migrates from the Sistema Arrecifal
Veracruzano (SAV) into Laguna de Mandinga during the spring, aided by the tide that flows along
the estuary of the Jamapa River. The population then decreases at the end of the summer, during
the rainy season, when salinity decreases (10 psu). The recruitment area of the polyps is probably
associated with the coral reefs in the SAV.

New range expansion of Caprella mutica Schurin, 1935 (Malacostraca: Caprellidae) to the German coast, North Sea
(pp S85-S89)
|
|
The caprellid amphipod Caprella mutica became rapidly established in the North Sea, on the west coasts
of Scotland and Ireland, the Irish Sea and English Channel. The first record for C. mutica from Jade Bay,
in the southern North Sea, is reported here. High densities exceeding three-hundred individuals per wood panel
(approximately 7000 ind./m-2) were found on wooden settlement panels in August/September 2009 associated
with the tube-building amphipod species Jassa marmorata and Corophium acherusicum. The extensive
mud-tube colonies of J. marmorata and C. acherusicum on the panels provide a suitable habitat for
C. mutica attachment.

First record of oriental shrimp, Palaemon macrodactylus Rathbun, 1902 in Varna Lake, Bulgaria
(pp S91-S95)
|
|
In September 2009 a non-native shrimp species was found at two sampling sites in Varna Lake,
a brackish coastal water body connected to the Bulgarian Black Sea. Diagnosis based on morphological
features confirmed that the examined individuals belonged to the species Palaemon macrodactylus
Rathbun, 1902. All specimens found were ovigerous, 2+ year females suggesting the presence of a viable
population in the system. Possible ways of introduction and community effects for Varna Lake are discussed.

First record of the invasive alga Caulerpa racemosa (Caulerpales, Chlorophyta) in the Gulf of Arzew (western Algeria)
(pp S97-S101)
|
|
The first invasive record of the green alga Caulerpa racemosa (Forsskål) J. Agardh in the Mediterranean
Sea was in 1990 in Tripoli (Libya) (J. Agardh) and since that period, this Chlorophyta has been rapidly
spreading to all Mediterranean countries. However, very few assessment studies have been carried out along
the Algerian coast. In this paper, we present, for the first time new observation data concerning
an indicated proliferation of this invasive species in Salamandre and Stidia (Gulf of Arzew, western Algeria);
both these sites are very important for sea fishing activities and traffic.

Recent expansion of the oriental shrimp Palaemon macrodactylus (Crustacea: Decapoda) on the western coasts of France
(pp S103-S108)
|
|
The invasive oriental shrimp Palaemon macrodactylus Rathbun, 1902 has considerably extended its
distribution in transitional waters along the Atlantic and Channel coasts of France during the period 2007-2010.
The most probable method of a primary introduction of this species is ballast waters, but passive transport
by water currents is also a possible mechanism of colonization (secondary introductions).
Palaemon macrodactylus is a powerful invader of transitional waters and these new populations
should be monitored in the future to assess any consequences to native species.

New records of Lobotes surinamensis (Bloch, 1790) in Maltese coastal waters
(pp S113-S116)
|
|
Lobotes surinamensis is considered as a rare occurrence in the Mediterranean Sea, being mainly
encountered in the eastern and central areas of the basin. The species was previously recorded only once
from the Maltese Islands, from offshore waters 45 miles south of the islands. Numerous recent records
of the species in Maltese nearshore waters suggest that the same species is becoming more common
in such waters, possibly hinting at the geographical expansion of populations of this thermophilic
fish species in the Mediterranean.

Update on geographic spread of invasive lionfishes (Pterois volitans [Linnaeus, 1758]
and P. miles [Bennett, 1828]) in the Western North Atlantic Ocean, Caribbean Sea and Gulf of Mexico
(pp S117-S122)
|
|
The Indo-Pacific lionfishes (Pterois volitans [Linnaeus, 1758] and P. miles [Bennett, 1828]:
Family Scorpaenidae) are the first non-native marine fishes to establish in the Western North Atlantic/Caribbean
region. The chronology of the invasion was reported last year (Schofield 2009) using records from the US Geological
Survey’s Nonindigenous Aquatic Species database. This article provides an update of lionfish geographic spread
(as of October 2010) and predictions of future range.

First record of Percnon gibbesi (H. Milne Edwards, 1853) (Crustacea: Decapoda: Percnidae) from Egyptian waters
(pp S123-S125)
|

On July 2010, the invasive crab Percnon gibbesi was photographed and captured along the coast of Alexandria
(Egypt, Eastern Mediterranean Sea). This represents the first observation of this species in Egyptian waters and
the easternmost record for the southern rim of the Mediterranean.
