The biological characteristics of eels from the Asi River, Turkey, were assessed between December 2017 and November 2018. Eels were sampled monthly using fyke nets (operated by professional fishermen), yielding a total of 509 specimens. Total length and weight were measured, sex, age and maturity stages (silver or yellow eel) were determined. Catch Per Unit Effort (CPUE) was calculated for both biomass per unit effort and numbers caught on a monthly and annual basis. The length‐weight relationships (LWRs) of silver and yellow eel was W = 0.009*TL3.22 (n = 262) and W = 0.0106*L3.09 (n = 247), respectively. The age of the sampled fish ranged from year class II to VI. Von Bertalanffy growth parameters were estimated as L∞=69.25 cm, K = 0.43 1/year, t0= −0.41 and phi prime index (ǿ)= 3.31 for all samples. The overall eel fishing mortality rate (F) was 0.31 year‐1, and the exploitation and survival rates of silver stage eels were estimated with 30% and 39%, respectively.
Bu çalışmada Hatay’ da bulunan 4 adet (Çevlik, Konacık, İskenderun ve Dörtyol) Balıkçı Limanı işletmelerinde finansal performansın nasıl ölçülebileceği ve analiz edilebileceği konusunda karşılaştırmalı ekonomik analiz yapılmıştır. Finansal performansın ölçülmesi için ihtiyaç duyulan veriler 2017 yılında balıkçı limanları işletmecilerinden birebir görüşülerek, aynı zamanda Tarım ve Orman İl Müdürlüğünden ve Mal Müdürlüğü’nden detaylı bir inceleme sonucu elde edilen sağlıklı bir veri tabanından elde edilmektedir. Çalışmanın sonunda balıkçı barınağı işletmelerinin pratik faaliyetleri ile ilgili yasal düzenlemeler ile düzenlemeler arasında farklılıklar olduğu tespit edilmiştir. Bu farklılıklarda balıkçı barınaklarının bölgedeki su ürünleri kooperatifleri tarafından işletilmesinin balıkçı barınaklarından beklenen faydayı sağlamadığı açıkça söylenebilir. Elde edilen verilerin değerlendirilmesi doğrultusunda bahse konu olan balıkçı limanları arasında finansal performans açısından bulunduğu konum ve limanı kullanan teknelerin çeşitliliğinden dolayı en iyi durumda olan balıkçı limanı Dörtyol balıkçı limanı olduğu belirlenmiştir.
This study aimed to analyze the risks of activities in fishing ports in the province of Hatay. Due to these activities, the fishing port is under health, good, labor, and environmental risks. In this study, risks were identified and evaluated at the four fishing ports. For this purpose; (1) A preliminary survey was conducted with stakeholders on the current situation and the functions of the fishing ports (2) brainstorm meetings were organized in three sessions in one day- three sections with 12 invited participants throughout the year 2016, (3) as a result of these meetings, risk assessments were carried out in terms of the risks identified, loss of health, good, labor, and environment for each fishing port. The risk matrices were presented graphically in terms of the risk effect and the frequency value, and risk tables were created for each risk. Approximately 20 (17-22) risks were identified for each fishing port. The risks identified for the fishing port were found similar these were different impact levels and frequency values. These differences were generally related to the location. The differences in the settlement structure of the fishing port caused advantages and disadvantages to risks of the fishing port risk. When risks were grouped and classified as administrative, structural, pollution, and security, the lack of management and supervision was striking. Risk analysis outputs were evaluated by using the “L type matrix” method with issuing by numerical and statistical comparisons for different fishing ports. The reason for the risks was due to incompatible legal regulations and control mechanisms rather than a benefit for fishing ports than regional and personal shortfalls with the current situation and expected. Finally, these assessments were the result of a regional study, but they were important both nationally and internationally fishing port risk lack of management. This article attempts to provide a range of knowledge, which is compulsory for managers.
