Turkish Copepoda Researchers Group

Our journey in the study of copepods in Türkiye began with the pioneering samplings in the Marmara Sea by Noodt in 1955. Despite this early start, the field did not see significant progress until the early 2000s. This change was spearheaded by the commendable efforts of Prof. Dr. Süphan Karaytuğ and Prof. Dr. Serdar Sak, whose leadership in a series of research projects accelerated the pace of discovery and understanding.

A particular focus has been on the interstitial and phytal harpacticoids living along the Turkish coastlines, which have been intensively sampled and studied since then. Our website aims to highlight the systematic studies of Copepods in Turkey and introduce the researchers contributing to this field. Additionally, we are excited to share a catalog of copepod species collected during these field studies (TCRC – Turkish Copepoda Research Collection).

In addition to our collections of free-living copepods, our webpage offers detailed information on numerous parasitic copepod species gathered from marine organisms in the Turkish seas. While the majority of our parasitic copepod collection is composed of species from the family Caligidae Burmeister, 1835—commonly known as “sea lice” and notorious for being major pests in cultured marine fish—we also possess a significant number of specimens from other copepod families. These include Lernanthropidae de Blainville, 1822, Lernaeopodidae Milne Edwards, 1840, Bomolochidae Calus, 1875, Pennellidae Burmeister, 1835, Hatschekidae Kabata, 1979, and Taeniacanthidae Wilson C.B., 1911, among others. As the Turkish Copepoda Researchers Group, we welcome collaboration with copepod researchers worldwide on future research projects and are committed to sharing our knowledge of copepods with future generations.

The Systematics and Biodiversity of Harpacticoid (Crustacea, Copepoda) Copepods Living in the Shallow and Tidal Zone Sandy Beach Habitats of the Black Sea

TBAG-1962 (100T120)

This study conducted along the Black Sea shores of Turkey aimed to shed light on the harpacticoid (Crustacea, Copepoda) fauna, contributing to the research that unveils the richness of Turkey’s copepod biodiversity. Led by Prof. Dr. Süphan Karaytuğ with the research assistance of Prof. Dr. Serdar Sak, the project culminated in February 2005, identifying 58 species and 2 subspecies within 41 genera across 21 families.

Determination of the Intertidal (Intersititial) and Phytal Harpacticoid (Crustacea, Copepoda) Fauna along the Mediterranean Coast of Turkey between Samandağ (Hatay) and Kalkan (Antalya)

TBAG-106T590

This pivotal study, led by Prof. Dr. Süphan Karaytuğ along with researchers Prof. Dr. Serdar Sak, Assoc. Prof. Dr. Alp Alper, and Assoc. Prof. Dr. Serdar Sönmez, has illuminated the previously undocumented diversity of interstitial and phytal harpacticoids living in the mediolittoral zone of Turkey’s Mediterranean coast. The research has identified 129 species within 76 genera and 30 families, marking a significant extension of the known Harpacticoida fauna. Notably, 128 of these species, excluding Euterpina acutifrons, represent new records for the Turkish Mediterranean shore. Furthermore, 6 families, 28 genera, and 95 species have been recorded for the first time in the Turkish fauna. Seven of the identified species (including one that also represents a new genus) are novel to science, expanding the global understanding of copepod biodiversity.

The Fauna of Intertidal and Phytal Harpacticoida (Crustacea, Copepoda) Living in the Mediolittoral Zone of Turkey’s Aegean Shores

KBAG-111T576

This comprehensive study, spearheaded by Prof. Dr. Süphan Karaytuğ and a team of researchers including Prof. Dr. Serdar Sak, Assoc. Prof. Dr. Alp Alper, Assoc. Prof. Dr. Serdar Sönmez, Dr. N. Özlem Yıldız, and Dr. Seher Kuru, aimed to uncover the diversity of interstitial and phytal harpacticoids in the mediolittoral zone of Turkey’s Aegean coast. Field studies were conducted across 119 stations between Fethiye (Muğla) and Dikili (İzmir), revealing 127 species and 3 subspecies within 72 genera and 26 families. Notably, this investigation has resulted in the first Turkish records of 2 families (Peltidiidae and Porcellidiidae), 11 genera, 53 species, and 3 subspecies.

Determination of the Harpacticoid Copepod (Crustacea, Copepoda, Harpacticoida) Fauna in the Intertidal and Phytal Habitats of the Mediolittoral Zone of Saros Gulf Coast

KBAG-212T105

This research project, overseen by Prof. Dr. Serdar Sak with the assistance of Assoc. Prof. Dr. Alp Alper and MSc. Orkan Metin, has been an extensive survey of the Harpacticoida fauna in the interstitial and phytal habitats of the mediolittoral zone of Saros Gulf. Across 29 sampled stations, 115 species/subspecies within 66 genera and 24 families were identified, all of which are new records for the study area. Notably, two families (Laophontopsiidae and Rhizothricidae), seven genera (Laophontopsis, Tryphoema, Itunella, Klieosoma, Parapseudoleptomesochra, Stylicletodes, Wellsopsyllus), and 36 species/subspecies have been recorded for the first time in Turkish seas.

Qualitative and Quantitative Examination of the Harpacticoid Copepod (Crustacea, Copepoda, Harpacticoida) Fauna Living in the Intertidal Habitat of Mediolittoral Zone of Sarımsaklı Beach (Balıkesir)

KBAG-215Z019

In this study, led by Assoc. Prof. Dr. Alp Alper with the guidance of Prof. Dr. Serdar Sak, the interstitial harpacticoid (Crustacea, Copepoda) fauna of Sarımsaklı Beach (Balıkesir) in the mediolittoral zone was investigated both qualitatively and quantitatively. Harpacticoid copepods were collected monthly from nine different sites along the beach between April 2016 and March 2017.

Widespread Mediolittoral Harpacticoid Copepods of the Turkish Coasts: Genetic and Taxonomic Diversity and Barcoding of the Species

KBAG-1119Z820

Led by Assoc. Prof. Dr. Serdar Sönmez, with Assoc. Prof. Dr. Alp Alper and the advisory of Prof. Dr. Süphan Karaytuğ, Prof. Dr. Serdar Sak, Prof. Dr. Ertan Mahir Korkmaz, and with the support of MSc. Dilara Bakmaz, this project sought to define the genetic diversity and establish species boundaries for 16 harpacticoid species found along the Turkish coasts. Utilizing mtDNA barcoding, the study stands as a pioneering effort to apply molecular markers to the Harpacticoida order for a broad geographic assessment. The comprehensive research involved sampling at 124 stations, with genetic and morphological data providing new insights into species differentiation. Significant findings include the detection of distinct genetic variations, indicating potential new species, and reaffirming the reliability of traditional morphological taxonomy in identifying these species. The results contribute a vital step towards understanding biodiversity within the Harpacticoida and offer a valuable framework for future taxonomic studies.
