Some aspects of the reproductive biology of the common carp (Cyprinus
carpio Linnaeus 1758) in Marmara Lake, Western Anatolia, Turkey
- Authors: Hakkı DERELİ; Turhan KEBAPÇIOĞLU, Yusuf ŞEN
  Abstract: There is a knowledge gap in some lakes of Turkey regarding the reproductive biology of the common carp (Cyprinus carpio Linnaeus, 1758), a very important freshwater commercial species. This study aims to determine for the first time the spawning period and length at first maturity (Lm50) from the reproductive characteristics of common carp in Marmara Lake in Western Turkey. A total of 650 individuals were sampled between December 2015 and November 2016. The sex ratio (♂:♀) was calculated as 0.88:1 (p

The Denotation Problematic of the Sea Area Between The Anatolian Coasts
and The Balkan Peninsula
- Authors: Murat Kağan KOZANHAN
  Abstract: The sea area, located between the Anatolian Coasts and the Balkan Peninsula, has been called by different names such as Aigaios Pontos, Pelagos Aigaion, Aigaion Pelagos in Greek, and Bahr-î Sefid, Cezyir-î Bahri Sefid, Inter-Islands, the Archipelago in Turkish. Societies or tribes, which trying to dominate this sea, have tried to name and interpret this sea by means of their own customs/traditions in accordance with their claims of domination. The mentioned sea is now called the "Aegean Sea" and this name is tried to be identified by the Greeks with the mythological hero Aegeus, the king of Athens, in Ancient Greece. However, it is necessary to investigate more etymological origins in naming geographical places. In this context, when the subject is examined, there are arguments the name "Aegean" has a language link with the Luwi language, which is the base culture of the Hellenic culture, and the words "Ög-Uz, Ög-İz", which means "stream, sea, water cover" in Proto-Turkic. In this study, the term Aegean; The mythological denotation of the reference in scientific studies will be discussed, evaluated within the etymological framework, and the terms the Archipelago, Inter-Islands used in the Ottoman Empire will be examined.

ANALYSIS OF COLLISION ACCIDENTS IN MARITIME TRANSPORTATION BY FTA METHOD
- Authors: Ali TÖZ; Müge BÜBER, Burak KÖSEOĞLU, Cenk ŞAKAR
  Abstract: The aim of this study is to determine the possible causes of collision accidents and identify the contribution of possibility on top events by using Fault Tree Analysis (FTA). A total of 62 collision accidents were considered between 2005 and 2020 and detailed technical data on marine accidents were provided from accident reports obtained by Marine Accident Investigation Branch (MAIB). The study found that most of the factors (E1/Misuse of navigational tools, E3/COLREG Rule-5 (Look-out)) that had the greatest effect on the collision were mainly due to the inadequacy to keep a safe navigation watch. For that reason, the findings of the study are very important in terms of determining the strategies to eliminate the risks for future accident prevention. For further research, it is recommended that consideration be given to a longer data period, including other navigational areas. In addition, alternative risk assessment methods should be applied considering other types of vessels for better comparisons.

MODELLING THE IMPACT OF THE OIL SPILL POLLUTION IN ILDIR BAY, TURKEY
- Authors: Murat GÜNDÜZ; Adil SÖZER
  Abstract: On the 18 of December 2016 a Panama-flagged ship, M/V Lady Tuna, was stranded off the coast of Ildır Bay, Turkey. According to the authorities 75.38 m3 (approximately 73 tons) heavy fuel-oil was released to the sea. It is the worst environmental disaster in the region mainly affecting the coastal areas of the Ildır Bay. To better understand the effects of the oil spill, a series of models were set-up in the region. The fate of the oil spill was predicted by MEDSLIK-II oil spill model forced by currents and temperature from an Aegean Sea circulation model based on NEMO (Nucleus for European Models of the Ocean) and winds from an atmospheric Re-Analysis model (ECMWF, ERA-INT). A couple of sensitivity experiments were conducted by changing the discharge duration and amount, the sensitivity results were compared with observations. The model results are in good agreement with the available observations. The model successfully predicts the path of the oil spill in the sea surface and its final destinations along the coast. The oil makes first land contact after 36 hours of accident. Due to the dominated and consisted southward currents and weak wind speed at the time of the accident, the effects of the oil were luckily limited without any high dispersion at the coast.

Vocational Preference Tendency Analysis of Maritime Transportation
Management Engineering Undergraduate Students
- Authors: İshak ALTINPINAR; Ömer ALADAĞ
  Abstract: Maritime is an essential profession for both our country and the world. 80-90% of the world trade volume is carried out through the seas and naturally seafarers. The most important part of the maritime profession is undoubtedly education. It is known that education at international standards in the field of maritime is provided by the standards of training certification and watchkeeping (STCW), published by the international maritime organization (IMO), and the flag state carries out the inspections. In order to receive undergraduate and associate degree education in the field of maritime in our country, it is necessary to enter the university exam and choose the relevant department of the university and win. The study aims to understand better the education and career paths chosen by maritime transportation management engineering students. This study aims to determine the preference tendencies of the students who prefer this department in universities that provide education in the maritime transport management engineering department and examine the professions that the students choose outside the department. As a result of the evaluations, the most popular preferences among the students who won maritime transportation management engineering were computer engineering, ship machinery management engineering, electrical-electronic engineering, and nursing departments. The increase in the score in the YKS exam has had a significant and negative effect on the rate of students choosing maritime transportation management engineering. The data in this study were obtained from the YÖK Atlas database.

Accumulation of Heavy Metals (Fe, Cu, Mn, Zn, Cd, Co and Pb) in
Hemiramphus archipelagicus Collette & Parin, 1978 and Hemiramphus far
(Forsskål, 1775) from Ibrahim Hyderi Fish Harbor, Karachi, Pakistan
- Authors: Farzana YOUSUF; Semra BENZER, Quratulan AHMED
  Abstract: In this study, the presence of heavy metals (Fe, Cu, Mn, Zn, Cd, Co and Pb) in the muscle tissue of Hemiramphus archipelagicus Collette & Parin, 1978 and Hemiramphus far (Forsskål, 1775) caught in the Ibrahim Hyderi Fish Harbor, Karachi, Pakistan was investigated. The concentration ranges of trace elements in muscles tissue of Hemiramphus archipelagicus and Hemiramphus far were found as follows, respectively: Fe: 19.570 - 62.140 µg g-1; Cu: 0.120 - 1.770 µg g-1; Mn: 0.001 -0.080 µg g-1; Zn: 7.230 - 36.450 µg g-1; Cd: 0.001 - 0.008 µg g-1; Co: 0.001 - 0.008 µg g-1; Pb: 0.002 - 0.080 µg g-1; Fe: 16.320 - 63.250 µg g-1; Cu: 0.130 - 1.220 µg g-1; Mn: 0.010 -0.080 µg g-1; Zn: 7.260 - 20.160 µg g-1; Cd: 0.000 - 0.008 µg g-1; Co: 0.000 - 0.001 µg g-1; Pb: 0.010 - 0.080 µg g-1. Metal concentrations in muscle tissues of Hemiramphus archipelagicus and Hemiramphus far were decreased as follows, Fe>Zn>Cu>Mn>Pb>Cd>Co. All metal accumulations in muscle tissues of Hemiramphus archipelagicus and Hemiramphus far samples collected from Ibrahim Hyderi Fish Harbor were not to be exceeding the limit and all values are under the permissible range. Therefore, it is important to continue to protect the Ibrahim Hyderi Fish Harbor against possible dangers that may increase heavy metal pollution, to ensure that the measures taken are maintained in the same way and to carry out regular controls.
