Abstract

An updated checklist carried out indicated the occurrence of 161 helminth species from wild marine fish species in Turkey, which includes 49 monogeneans, 63 digeneans, 18 cestodes, 17 nematodes, 11 acanthocephalans and three annelids, from 88 different fish (86 native, two migratory) species. Since the publication of the checklist of helminth parasites of marine fishes in Turkey over nine years ago (Öktener, 2005), there have been a number of new records. This update includes these additional records and has allowed the correction of those errors and omissions that were present in the previous version. The parasite species list is arranged by phylum and class, providing parasite species name, host fish, location of host fish capture and author, and date of published record. The host list consists of all parasite species listed by host species. All parasites and their hosts are confirmed with the recent systematic accounts and full taxonomic account.

Abstract

The parasitic copepod, Lernanthropinus trachuri () (Copepoda, Siphonostomatoida, Lernanthropidae)was found on the Mediterranean horse mackerel, Trachurus mediterraneus in Bandırma Bay, Turkey. The aim of this study is to present female Lernanthropinus trachuri with morphological characters with photos from Turkey. The details unseen in photos were supported with drawings. All parasites were firmly attached to the gill filaments of the host. This parasite is also specific for the genus Trachurus (). Therefore, this parasite may use as biomonitor or tag species for fish stock studies in Turkey.

Abstract

This new checklist is an update of helminths of freshwater fish from Turkey. The last publication of a checklist of helminth parasites of freshwater fish in Turkey was over 11 years ago (Öktener, 2003), and there have been a number of new records. This update includes additional records and allows for the correction of errors and omissions that were present in the preceding version. The revision literature indicated the occurrence of 123 parasite species which included 60 monogeneans, 20 digeneans, 20 cestodes, 11 nematodes, seven acanthocephalans, five annelids from 71 different wild fish (64 native, four transitional, three introduced fish) species from freshwater in Turkey. Parasites not identified to species level are listed separately, and not included in the resulting comments, because of reporting different host species. Cyprinidae, with 50 species, is the dominant family among the examined fish with regard to species diversity

Abstract

53 striped surmullet, Mullus surmuletus Linnaeus, 1758 (Teleostei, Mullidae), were collected from the Marmara Sea, Turkey and examined for metazoan parasites in July 2017. The parasitic copepod, Peniculus fistula fistula Nordmann, 1832 (Pennellidae), was collected from all the hosts, both on fins and body surface. This is the second report of this copepod in Turkish marine waters. Although Peniculus fistula fistula was reported for the first time on Coryphaena hippurus Linnaeus, 1758 by Öktener (2008), there was an indefiniteness and doubt about the occurrence of this parasite. This study aimed to confirm occurrence of Peniculus fistula fistula in Turkey and to present revised host list with comments.

Abstract

This review presents the occurrence of 62 parasitic copepod species from 72 different fish species (64 wild, two cultured, seven from aquarium) from Turkey.

The parasite species list is arranged by providing parasite species name, host fish, location of host fish capture and author, date of published record.

All parasites and their hosts are confirmed with the recent systematic accounts and full taxonomic account according to literature and internet database. Siphonostomatoida with 47 species and Caligidae with 12 species are the dominant order and family among parasitic copepoda with regard to species diversity, host distribution and location.

Abstract

Mothocya epimerica Costa, 1851 (Flabellifera: Cymothoidae) is a cymothoid parasite of fishes belonging to Atherinidae (Atherina hepsetus, Atherina boyeri) from Mediterranean Sea, Black Sea and Atlantic Ocean. recorded this parasite for the first time in Turkey. The mentioned authors presented some morphological characters, although, some characters are not explained in the publication. Some morphological characters seen on the mandible, maxilliped, maxilla, maxillue and the spines on pleopods of the female of M. epimerica are shown. The characters presented in our study are based on the drawings made from collected specimens.

Abstract

In this study, the distribution and abundance of Artemia salina in 10 different stations of the Salt Lake basin were investigated. In addition, its relationship to pH, dissolved oxygen, temperature, electrical conductivity and water levels were analyzed. Field studies were carried out from July to August of 2010. Artemia salina was observed in five of these stations. Artemia salina was not seen in some stations that have high electrical conductivity. It is determined that, in the station named Tersakan Lake where electrical conductivity was 154 mS/cm, Artemia salina is more abundant when compared to the other stations. But as underground water pumps that are built for the irrigation of agricultural lands decrease water levels, Artemia salina’s life is under threat.

Abstract

Lepeophtheirus europaensis Zeddam, Berrebi, Renaud, Raibaut and Gabrion, 1988 (Copepoda, Siphonostomatoida, Caligidae) an ectoparasite of flatfishes, was reported for the first time in the Sea of Marmara Coasts.

Some morphological characters of this parasitic copepod are given using original photographs and drawings. The general morphology, the mouth parts (antenna, mandible, maxillule, maxilla, and maxilliped), the outgrowth developed between the post-antennary process and the antenna, the setal and spinal formula from first leg to fourth leg in this study are compatible according to the specific literature.
