    A total of 86 different fish species were recorded in Istanbul Fish Market between 1998 and 2001. During these years, the highest productions were recorded for european anchovy (Engraulis encrasicholus Linnaeus, 1758), horse mackerel (Trachurus trachurus Linnaeus, 1758), bonito (Sarda sarda Bloch, 1793), bluefish (Pomatomus saltatrix Linnaeus, 1766) and whiting (Merlangius merlangus euxinus Nordmann, 1840). Total production amount of these 5 species was 80.1% of the production for the investigated years. Annual fish production varied between 23825 and 25228 ton from 1998 to 2000, however, the total production of 2001 was recorded as 36771 ton, an increase of 51%. November and October were observed as the highest production months during the fouryear period. In 2001, the highest increase in terms of percentage compared to the previous three years production was observed in bluefish (497%).

    An investigation on some population parametres of European pilchard (Sardina pilchardus Walbaum 1792) in the Dardanelles
    (2002) Tekinay, Ahmet Adem; Akyüz, Pınar; Güroy, Derya; Kahyaoğlu, Gülçin Ebru; Alpaslan, Mustafa
    In this study, the lenght-weight relationship, condition factor (CF), gonadosomatic index (GSI) and meat yield of 363 Europen pilchard (Sardina pilchardus Walbaum,1792) sample from Dardanelles were studied between Semtember 2001 and April 2002. The lenght-weight relationship was calculated as W=0.0172L2.68; R2=0.71. Mean condition factor of males and females varied between 0.66-0.87% and 0.68-.0.86%, while mean GSI values were 0.34-4.83% and 0.47-5.95%, respectively. Percentage meat yield of males and females were varied as 64.21-75.56 and 64.20-81.50, respectively.

    Çanakkale Balık Halinde pazarlanan su ürünleri ve Çanakkale Bölgesi üretim miktarlarının karşılaştırılması.
    (Ege Üniversitesi Su Ürünleri Fakültesi Dergisi, 2002) Tekinay, Ahmet Adem; Alpaslan, Mustafa; Özen, Özcan; Akyüz, Pınar; Güroy, Derya
    A comparison between the records of Çanakkale Fish Market and fisheries production of Çanakkale Region from 1996 to 2001. In this study, Çanakkale Fish Market records and Çanakkale fisheries production data obtained from Ministry of Agriculture and Rural Affairs, Province Directorate of Çanakkale were investigated from 1996 to 2001. The highest market records (432.0 ton) and fisheries productions (22 050.6 ton) were observed in 2001. For the years investigated, the sum of the monthly production in the fish market were highest in October and November (183.6 and 183.5 ton, respectively). A total of 65 different marine species were recorded in Çanakkale Fish Market whereas only 25 different marine species were reported by Ministry of Agriculture and Rural Affairs, Province Directorate of Çanakkale. Although the greatest amount in the Fish Market were gilt sardine, anchovy, and bluefish, the greatest fishing production in the Çanakkale region were reported as gilt sardine, tuna and bluefish. In contrast to the fishing production of Çanakkale region, tuna entered the Fish Market only in August, 2001. Çanakkale Fish Market records and the fishing production of Çanakkale region did not differ only in the amount but also in the species composition. Based on such conflicting statistics, decisions on fisheries management would be erroneous.
