O prisutnosti uspostavljene populacije kosirice mjesečice, Symphodus melops (Linnaeus, 1758), u središnjem Sredozemnom moru s bilješkama o njezinom staništu i ekologiji

The presence of a well-established population of the corkwing wrasse, Symphodus melops (Linnaeus, 1758), is reported for the first time from the central Mediterranean Sea (southwestern Sicily). We discuss about the presence of the species in the area, with notes on its habitat, ecology and distribution.U ovom radu se navodi prisutnost utemeljene populacije kosirice mjesečice Symphodus melops (Linneus, 1758) koja je prvi put zabilježena u središnjem Sredozemnom moru (jugozapadna Sicilija). Autori iznose podatke o pristunosti vrste u tom području zajedno s bilješkama o njezinom staništu, ekologiji i distribuciji

A new exotic fish for the Mediterranean Sea: Chaetodon auriga Forsskål, 1775 (Perciformes: Chaetodontidae)

The presence of Chaetodon auriga Forsskål, 1775 is reported for the first time from the Mediterranean Sea. A specimen was spearfished in 2015 in the central Mediterranean Sea and was in all likelihood an aquarium release. This and similar cases are discussed, with particular emphasis on exotic fishes notoriously known to be commonly kept in aquarium

Prvi zapis o novoj obojanosti kirnje zlatice, Epinephelus costae (Steindachner, 1878) (Actinopterygii: Serranidae) i prvi zapis o leucizmu ugora, Conger conger (Linnaeus, 1758) (Actinopterygii: Congridae): građanski doprinos znanosti

In many fish, color patterns are striking features and can play an important role in both natural and sexual selection. Furthermore, details of color patterns are in some cases valid tools for species identification. However, fish can also show some genetic abnormalities, such as albinism and leucism. In this research, we report for the first time a new color pattern for Epinephelus costae (Steindachner, 1878), for which it is known an ontogenetic shift in color pattern, and the first case of leucism in Conger conger (Linnaeus, 1758).Kod mnogih riba obojanost ima upečatljiva obilježja i može igrati važnu ulogu kako u prirodnom tako i u spolnom odabiru. Detalji o uzorcima boja u nekim su slučajevima valjani alat za identifikaciju vrsta. Međutim, riba može pokazati i neke genetske abnormalnosti, poput albinizma i leucizma. U ovom istraživanju prvi put izvješćujemo o novoj obojanosti Epinephelus costae (Steindachner, 1878.) i o prvom slučaju leucizma kod ugora, Conger conger (Linnaeus, 1758)

Prvi podaci o staništu, prehrani i dužinsko-masenom odnosu vrste Gobius incognitus Kovačić & Šanda, 2016 (Pisces: Gobiidae)

In this work, we present first data on biological and ecological aspects of Gobius incognitus from specimens from the Ionian Sea (central Mediterranean Sea). In particular, we provided first data on habitat preference, diet and length-weight relationship of G. incognitus on material with confirmed species identity. The species preferred “mixed bottom” (sand and rocks), where it reached relatively high abundances. The diet analysis showed that G. incognitus is a generalist and opportunistic feeder. However, small benthic crustaceans were the most important prey group. The mean total length of specimens was 6.72 ± 1.85 cm and the growth was positive allometric.U ovom radu iznose se prvi podatci o biološkim i ekološkim značajkama vrste Gobius incognitus na temelju uzoraka iz Jonskog mora (središnji dio Sredozemnog mora). Posebno se ističu podatci o staništu, prehrani i dužnsko - masenom odnosu. Vrsta Gobius incognituspreferirala je „miješano dno“ (pijesak i stijene), gdje je dostigla relativno veliku brojnost. Analiza prehrane pokazala je da G. incognitus slijedi oportunistički način prehrane. Međutim, mali bentoski rakovi bili su najvažniji plijen. Srednja ukupna dužina iznosila je 6,72 ± 1,85 cm, a rast je bio alometrijski pozitivan

First record of the mottled spinefoot Siganus fuscescens (Houttuyn, 1782) in Mediterranean waters: a Facebook based detection

The occurrence of Siganus fuscescens was recorded on March 1st 2020, within the harbour of Gioia Tauro, southern Tyrrhenian Sea (38.44428 N, 15.90459 E). The capture was realized by a recreational fisher and shared through a Facebook group. Here we illustrate this new record and discussed its relevance for Mediterranean bioinvasion research

Novi zapisi dviju bitnica s jugoistočne obale Sicilije (Jonsko more) i razmatranja o njihovoj prisutnosti i obilju

New records of Pseudocaranx dentex (Bloch & Schneider, 1801) and Seriola fasciata (Bloch, 1793) are reported from the Mediterranean Sea. During the period 2013-2017, we have collected several records of both species from the south-east coast of Sicily (Ionian Sea). On the basis of our and published data, we can consider S. fasciata as a relatively common species in the area, commonly caught with purse seine around FADs in summer and autumn; while, P. dentex remains basically a rare species, occasionally caught with trammel nets or gillnets. This work represents the first well-documented records of both carangid species in the south-east coast of Sicily.U ovom radu se iznosi novi nalaz šnjurka Pseudocaranx dentex (Bloch & Schneider, 1801) i Seriola fasciata (Bloch, 1793) u Sredozemnom moru. Tijekom razdoblja 2013.-2017. autori su za obje vrste prikupili nekoliko zapisa o nalazu s jugoistočne obale Sicilije (Jonsko more). Na temelju autorskih i drugih objavljenih podataka, S. fasciata može se smatrati relativno čestom vrstom na tom području, obično uhvaćenom mrežom plivaricom oko FAD-ova u ljeto i jesen; dok je P. dentex rijetka vrsta povremeno ulovljena trostrukim ili jednostrukim mrežama stajaćicama. U ovom se radu iznose dokumentirani nalazi obje bitnice na jugoistočnoj obali Sicilije

Prvi potvrđeni zapis o vrsti Pomatoschistus microps(Krøyer,1838) (Pisus: Gobiidae) iz Jonskog mora s bilješkama o staništu i rasprostranjenosti

Two specimens of the common goby (Pomatoschistus microps) were observed in the estuarine environment of the River Asinaro (Sicily). These records represent the easternmost and southernmost observations of the species in the Mediterranean Sea, and the first confirmed record in the Ionian Sea (central Mediterranean Sea). We also provide notes about its habitat and current distribution in the Mediterranean Sea.Dvije jedinke vrste Pomatoschistus microps zabilježene su u okolišu ušća rijeke Asinaro (Sicilija).Ovaj nalaz predstavlja najistočniji i najjužniji nalaz vrste u Sredozemnom moru i prvi potvrđeni nalaz u Jonskom moru. Također se navodi njegovo stanište kao i trenutna rasprostranjenost u Sre-dozemnom moru

Najzapadniji nalaz vrste Terapon jarbua (Forsskål, 1775.) u Sredozemnom moru: nova nezavičajna vrsta ribe u Libiji

The occurrence of the Indo-Pacific fish Terapon jarbua (Forsskål, 1775) is documented for the first time from Libya. This record represents the third and westernmost observation of the species in the Mediterranean Sea. Introduction pathway for this fish in Libyan waters and in the Mediterranean Sea in general is discussed.Nalaz indo-pacifičke vrste Terapon jarbua (Forsskål, 1775.) po prvi put je dokumentiran na području Libije. Ovaj nalaz predstavlja treće i najzapadnije opažanje ove vrste u Sredozemnom moru. U radu se raspravlja o razlozima pojavljivanja ove ribe u libijskim vodama i Sredozemnom moru općenito

Goniadella bobrezkii (Annenkova, 1929) (Annelida, Polychaeta): first record in the Italian waters

Goniadella bobrezkii (Annenkova, 1929) is a small goniadid worm identifiable by the number of anterior uniramous parapodia and by the position of the posterior spine-like notochetae arising dorsal to dorsal cirri. Although it was already reported in the Mediterranean Sea, it has never been found in the Italian waters. This study represents the first generic and specific record of G. bobrezkii along Italian coasts. A total of 25 specimens were collected in a Posidonia oceanica (L.) Delile bed, depth of 7 m, off Civitavecchia (Rome)
