Recreational Fishing on the Coastal Hot Spots of Izmir Inner Bay (Aegean Sea, Turkey) : Socio-economics and Management Implications

In this study, we analyzed social and economic dimensions of shore-based recreational fishing (RF) along Izmir Inner Bay in the Metropolitan Province Izmir of Turkey. 634 shore-based recreational fishers were interviewed via on-site face-to-face interviews during the fishing activity from January to December in 2016. Market value approach was utilized to calculate net economic values and expenses of recreational fishers along in eight coastal districts, Goztepe, Karatas, Konak, Pasaport, Alsancak, Bayrakli, Karsiyaka and Bostanli along the coast of the inner bay. The annual fishing efforts demonstrated significant differences among districts. For example; Bostanli fishers that have higher education levels with higher income spent higher time for RF but, finally, this attitude of Bostanli fishers resulted in low CPUE levels. Considering the RF experience of Bostanli fishers, they are either not likely or able to target or catch bigger or more fish. In contrast, Goztepe fishers seems much professional compared to fishers by having the highest amount of catch in shortest time compared to rest of the districts. The highest mean CPUE was observed for Goztepe, Karatas and Konak fishers even so, these CPUE amounts were much under the ones determined in previous studies in Turkey. Considering the catch composition of fishers, S. auratus was the most common catch for all fishers. Secondly, D. labrax and Mugilid species constituted the majority. High fishing related expenditures were observed in all districts, then harvesting values reached quite high levels considering the previous studies. To conclude, RF in Izmir Inner Bay of Turkey is great social and economic activity by generating increase in RF related expenditures, jobs and indirect economic activity in services sector. The results of this study provide an update information of the recreational fishers' profile to help regulate recreational fishery.Peer reviewe

Rekreativni ribolov na turskim obalama srednjeg i istočnog Crnog mora: biološki, socijalni i ekonomski aspekti

This study investigated biological, social and mainly economic dimensions of recreational fishing (RF) in 8 coastal Middle and Eastern Black Sea provinces of Turkey. In all provinces, a total number of 874 shore-based recreational fishers were interviewed via on-site face-to-face interviews during the fishing activity or at access points being monthly from January to December in 2015. Market value with RF index of added value approaches were used to calculate economic gains and losses from RF. The consistency was observed with the high education levels, high expense and high market value for fishers in the Middle Black Sea provinces; Kastamonu, Samsun, Sinop and Ordu. In all provinces, the harvesting costs stayed far below the average market prices of target species. Also, positive values of RF index were observed in all provinces. The species catch composition in Western and Eastern provinces did not show great differences. Furthermore, even if the habitat type along the Black Sea coast of Turkey did not show great variations, in the Western provinces some certain species including T. trachurus, S. sarda, B. belone, P. saltatrix, M. cephalus were caught in higher amounts. To summarize, RF along the Black Sea coasts of Turkey is an industry creating high economic returns by expenditures, jobs, catch value and further increased indirect economic impact in services sector.U ovoj studiji se iznose istraživanja biološke, društvene i ekonomske dimenzije rekreacijskog ribolova (RF) u 8 srednje obalnih i istočnih pokrajina Crnog mora u Turskoj. U svim pokrajinama ukupno je 874 obalnih rekreativnih ribara anketirano izravnim intervjuima (razgovorom licem u lice), te tijekom ribolova ili pri pristupnim točkama mjesečno od siječnja do prosinca 2015. godine. Tržišna vrijednost prema indeksu rekreativnog ribolova i dodane vrijednosti korištena je za izračun ekonomskih dobitaka i gubitaka kod rekreativnog ribolova. Konzistencija je promatrana s obzirom na visoki stupanj obrazovanja, visoke troškove i visokom tržišnom vrijednošću za ribare u slijedećim pokrajinama srednjeg Crnog mora: Kastamonu, Samsun, Sinop i Ordu. U svim pokrajinama troškovi ribolova bili su daleko ispod prosječnih tržišnih cijena ciljanih vrsta. Također, u svim pokrajinama zabilježene su pozitivne vrijednosti indeksa rekreativnog ribolova. Sastav ulova u zapadnim i istočnim pokrajinama nije pokazao velike razlike. Nadalje, iako stanišne vrste duž crnomorske obale Turske nisu pokazivale velike varijacije, u zapadnim provincijama neke određene vrste, uključujući Trachurus trachurus, Sarda sarda, Belone belone, Pomatomus saltatrix, Mugil cephalus bile su uhvaćene u većim količinama. Ukratko, rekreativni ribolov na crnomorskim obalama Turske je industrija koja stvara visoki ekonomski povrat izdataka u vidu radnih mjesta, ulovne vrijednosti i daljnjeg povećanja neizravnog ekonomskog utjecaja u sektoru usluga

Laboratuvardan Kliniğe Transplantasyon Pratiği

Transplantasyon; Temel Tıbbi Bilimler, Moleküler Tıp, Genetik ve İmmünolojiden klinik uygulamalardan destek alan multidisipliner bir tıp dalıdır. Temel bilimlerdeki başarılı çalışmaların kliniğe uygulanması, klinikte karşılaşılan sorunların da, oluşturulan deneysel hayvan modellerinde irdelenmesi, elde edilen bilgilerin klinik uygulamalara aktarılması; diğer deyişle tecrübelerin “Translational” özellikli olması günümüz transplantasyon çalışmalarında bir gerekliliktir. İmmün sistemin bileşenlerinin ve reaksiyonlarının iyi bilinmesi, hücreler arası ilişkilerde greftin reddi ya da kabul edilmesinin şartlarını doğru anlamak ve uygun laboratuvar yöntemleri ile klinik durumun aydınlatılması transplantasyonda stratejik önemdedir. Bu nedenle, klinik transplantasyon çalışmaları yapanlar temel bilimler bilgileri ile de donanımlı olmalıdırlar. Multidisipliner bir dal olma bilinci ile yapılan klinik transplantasyon çalışmalarında başarı yakalanmaktadır. Laboratuvardan Kliniğe Transplantasyon kitabımızda tüm yönleri ile transplantasyonun organizmaya etkileri ve bunların klinik sonuçlarını, çalışmalarımızın ışığında sunmayı ve tartışmayı hedefledik.

Interactions and accumulation differences of metal(loid)s in three sea cucumber species collected from the Northern Mediterranean Sea

This study was conducted on Holothuria polii, Holothuria tubulosa, and Holothuria mammata collected from five stations with different depths in the Northern Mediterranean Sea. The body walls and guts of these holothurians were examined in terms of interactions of 10 metals (iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), chromium (Cr), cobalt (Co), vanadium (V), nickel (Ni), cadmium (Cd), and lead (Pb)) and one metalloid (arsenic (As)) using a multivariate analysis, and interspecies differences were determined. The multivariate analysis of variance (MANOVA) revealed significant differences between the species in terms of metal(loid) accumulations. The principal component analysis (PCA) showed a more association between H. tubulosa and H. polii with regard to the accumulation. The cluster analysis (CA) located Pb concentrations of the guts to the farthest place from all elements regardless of the species. A correlation analysis displayed that the element concentrations of the guts were more closely related to each other compared with those of the walls. The most inconsistent element in terms of correlations was the gut Fe contents. Accordingly, while Fe concentrations of H. mammata and H. tubulosa were correlated with all elements (except Pb) in divalent metal transporter 1 (DMT1) (divalent cation transporter 1 (DCT1) or natural resistance-associated macrophage protein 2 (NRAMP2)) belonging to the NRAM protein family, this was not the case in H. polii. Consequently, significant relationships between accumulated metal(loid)s that changed by tissues and sea cucumber species were observed

Effects of anthropological factors on the metal accumulation profiles of sea cucumbers in near industrial and residential coastlines of Izmir, Turkey

This study details the metal and metalloid accumulation profiles of three species of sea cucumbers (Holothuriamammata, Holothuriapolii and Holothuriatubulosa) native to Aliaga and Ildir (Izmir, Turkey), two regions that are representative of industrial and residential districts, respectively. A total of 11 elements were analysed (Fe, Cu, Mn, Zn, Cr, Co, V, Ni, Cd, Pb and As) from gut and body wall tissues of holothurians and in sediment samples. The Mann-Whitney U analysis revealed statistical difference between locations and tissues. Accumulations of Aliaga samples were significantly higher than Ildir samples with respect to Zn, V, Mn, Cr, Fe and Co while accumulations were significantly higher in the gut than body wall regardless of the region for all elements tested. The correlation analysis showed more and stronger correlations in the gut than in the body wall. In addition, metal(loid) concentrations in the sediment were found to correlate strongly with these in the sea cucumber gut. The cluster analysis displayed totally different element accumulation pattern for Aliaga and Ildir in the both tissues which indicate that anthropogenic effects start to alter the bioaccumulation of metal(loids). Biota-sediment accumulation factors (BSAF) and metal contamination index were calculated to determine the extent of metal(loid) uptake and to compare total elemental accumulation at each region. Gut tissue elemental BSAF is higher than body wall for all elements at both areas. Cd has the highest value with 5.582 (gut tissue) and the lowest are Ni, V and Cr with 0.001 (body wall tissue). In addition, sediment results were compared with previous studies and sediment quality guidelines and found to exceed the lowest effect level (LEL) values for As and Ni
