Abstract

Habitat of the family Priacanthidae is tropical and subtropical Atlantic, Indian, and Pacific oceans. The features of the  family members are generally very big eyes, deep bodies, upturned mouth,  and generally reddish color. In the this paper, we report the presence of an arrow bulleye Priancanthus sagittarius in coast of Turkey waters in the Mediterranean Sea. On the 27th December, 2017, a single specimen of P. sagittarius was collected by Mr. Hüseyin Çınar, captain of the commercial bottom trawler Furkan Reis vessel, off the TaÅŸucu, Mersin (36°07'2.82"N 33°51'6.42"E) Turkey coasts. The specimen of P. sagittarius was collected at a depth of approximatetly 100 m by a bottom trawl net; the mesh size of 22mm. The collected specimen of arrow bulleye P. sagittarius was 255 mm in total length (TL) and 307 g in total weight (TW). The finding of the present study is the first record of specimen along shores of the Mediterranean of Turkey. This record suggests that this species is spread towards to west along in the Mediterranean.

Abstract

The first occurence of the mole crab (Albunea carabus L. 1758) in the Gulf of Antalya. During a commercial shrimp fishery oparation in May, 2016, A different type of crab was caught in the Gulf of Antalya, Bogazkent (Köprüçayı). This unknown sample was brought to Akdeniz Üniversity Fisheries Laboratory and It was stored. Sample was caught with shrimp nets that were left at depths of 10-20 m in the Gulf of Antalya, Bogazkent (Köprüçay River). It has been determined that this elongated mole, caught in the identification of the species, is Albunea carabus L. 1758, known as the dengue. Mole crab (Albunea carabus L. 1758) was reported for the first time from the Gulf of Antalya via this article.Keywords: Albunea carabus; the Gulf of Antalya; mole crab

Abstract

In this study, 515 Farfantepenaeus aztecus specimens were investigated in the Gulf of Antalya and 304 (59,02%) specimens (167 females and 137 males) infested with Bopyrid isopod parasite Epipenaeon ingens were found. In this study, we aimed to define the rate of infestation and its impact on survival rate and growth rate. Relationship of length- weight and condition factor values were lower in infested specimens compared to non-infested ones. While gonadal development was observed in different stages of non-infested female specimens, no gonadal development was observed in any infested specimens. Moreover, darker color and harder shell structure were observed in parasitized shrimps. During this research, infestation onto P. semisulcatus and P. kerathurus had been seen rarely.Keywords: Gulf of Antalya; Epipenaeon ingens, Farfantepenaeus aztecus; growth; reproduction

Abstract

Fishermen caught a different eel species at night with hook on July 7, 2019 (36°48'59.21"N: 30°38'23.44"E). This fish has not been seen before in the Gulf of Antalya. This fish was identified as Pisodonophis semicinctus (Richardson, 1848). With the identification of this fish, a new species was added to the fish fauna of the Gulf of Antalya.  In the present paper, we reported P. semicinctus for the first time from the Gulf of Antalya, Turkey (North-Eastern Mediterranean), for the third time from marine waters of Turkey.Keywords: Occurence; Pisodonophis semicinctus; the Gulf of Antalya

Abstract

Penelitian ini bertujuan untuk melihat resistensi Lactococcus garvieae hasil isolasi dari ikan rainbow trout sakit ( Oncorhynchus mykiss). , W.) di peternakan di Antalya, Wilayah Mediterania Turki untuk berbagai antibiotik. Studi sampel dimulai pada Juli 2018 dan selesai pada September 2018. Studi pengambilan sampel dilakukan di peternakan ikan trout komersial di distrik Kemer, Korkuteli, Serik dan Manavgat di Antalya. Sembilan puluh ikan selama masa studi. Bobot tubuh ikan berkisar antara 110 gram hingga 350 gram. Untuk studi bakteriologis, inokulasi disiapkan dari mata dan organ dalam ikan yang hampir mati dan diinokulasi ke BHIA. Cawan petri yang telah diinokulasi diinkubasi pada suhu 25 ± 2 ° C selama 72 jam.Setelah masa inkubasi, ditentukan morfologi dan warna koloni bakteri. Berbagai uji morfologi, fisiologis dan biokimia dilakukan terhadap isolat tersebut. Teknik PCR digunakan sebagai Konfirmasi L . garvieae . Uji resistensi antibiotik terhadap isolasi dilakukan secara in vitro . Beberapa Resistance Antibiotik (MAR) Nilai indeks L . isolat garvieae juga dihitung. Temuan terdeteksi pada semua ikan yang terkena.Warna kulit menjadi gelap, eksophthalmia unilateral dan / atau bilateral dengan perdarahan periokular, basal perut, penggelapan warna limpa dan splenomegali, perdarahan di organ dalam dan sebagai situs yang terdeteksi pada ikan. Berdasarkan hasil fenotipik dan PCR, isolat tersebut teridentifikasi sebagai Lactococcus garvieae . Diketahui bahwa semua isolat resisten terhadap ampisilin, asam nalidiksat, nitrofurantoin, asam oksalinat dan sulfametoksazol serta rentan terhadap amoksisilin, enroflooksasin, florfenikol dan kloramfenikol. Nilai indeks MAR isolat berkisar antara 0,3 sampai 0,6.
