The total amounts of saturated, monounsaturated and polyunsaturated fatty acids were found to be 26. win-ter, respectively. In winter, ω9 fatty acids amount was the lower than that of ω3 and ω6 fatty acids. .The ω6/ω3 fatty acids, arachidonic acid to eicosapentaenoic acids, ratios were 0.30 and 0.98 in spring, 0.38 and 0.97 in summer, 0.44 and 1.11 in autumn, and 0.43 and 1.34 in winter, respectively. The results obtained showed that the amount of polyunsaturated fatty acids in muscle tissue of pike is very high in all seasons, and this fish might be an impor-tant source of ω3 fatty acids for mankind.

Characteristics of sexuality status, age groups, growth and reproduction as well as condition factor of Cyprinus carpio (L. 1758) population, which inhabits this dam lake and is of economic importance, was investigated. The age composition of Cyprinus carpio samples were determined to have ranged from I to VIII. Sexual distribution proved to be 41,83 % for females and 43,02 % for males. Minimum fork length of this species was found to be 138 (mm), minimum weight 51 (gr), maximum fork length 525 (mm), and maximum weight 2724 (gr). The highest agespecific number within the population was observed in age group III, whereas the lowest one was in age group VII. Minimum and maximum condition factors were found to be 1,69 in age group VI and 2,26 in age group III, respectively. As far as the seasons are concerned, minimum condition factor was observed 1,84 in July, whereas the maximum one was 2,17 in June. Sexual maturity age was found to be III in the males and IV in the females. Reproduction period was determined to be June and July. GSI values based on the months ranged from 1,64 to 18,78. Fecundity has increased, rising from the age group IV to VIII.

The ages of S. cephalus were determined in the range of I to V. of the investigated samples, 45.36% were female and 43.46% were male. The minimum fork length of this species was 131 mm, the lowest weight was 30 g, the maximum fork length was 307 mm and the highest weight was 438 g. Relation between length and weight was calculated as W = 0.091 x L 2.43 (female+male). First sex maturity was attained at the age of II in males and III in females and spawning occurs between may and july. Monthly gonadosomatic index (GSI) values varied from 1.23 to 7.87. Fecundity increased with the age.

However, the toxicity of Zinc Pyrithione (ZnPT) remains uncertain. In this study, tilapia (Oreochromis niloticus L., 1758) fingerlings exposed to 1/24 (2.5 μg/L) and 1/12 (5 μg/L) of the 96 hour LC50 value of ZnPT effects were investigated histopatologically. Results of histological examination, showed no histopatological findings in the gonad, heart, kidney, muscle, spleen and intestine tissues after subletal ZnPT exposure, however epithelial lifting, edema, telangiectasia and hyperplasia in gill tisue; passive hyperemia, hydropic degeneration, lymphocyte infiltration and fatty degeneration in liver; hyperemia in skin tissues and excessive bile accumulation in gall bladder were determined.

Calisma sonuclari Apa Baraj Golu’nde onemli bir kirlilik olmadigini gostermistir, bununla birlikte, tarim alanlarinin sulanmasi nedeniyle yaz aylarinda su seviyesindeki bir azalma kirlilik parametreleri seviyesinde bir artisa neden olmustur

Arastirma alanlarini temsil edecek sekilde Ayhanlar Baraj Golu’nde 3, Damsa Baraj Golu’nde 3, Tatlarin Baraj Golu’nde 1 ve Kizilmak’ta 4 istasyon olmak uzere toplam 11 istasyondan balik ornekleri toplanmistir. Calisma suresince 3 farkli familyaya ait 9 tur ve 1 alttur olmak uzere 10 takson tespit edilmistir. Bunlar; Cyprinadae familyasindan Cyprinus carpio, Tinca tinca, Carrasius gibelio, Carrasius auratus, Squalius cephalus, Capoeta tinca, Barbus plebejus escherichi, Capoeta sieboldii, Siluridae familyasindan Silurus glanis ve Percidae familyasindan Sander lucioperca turleridir.Arastirma alaninda yakalanan turlerin ve altturlerin teshisinde kolaylik saglamak amaciyla familya, tur ve alttur duzeyinde, ayirici karakterlerden olusan tayin ana...

Characteristics of sexuality status, age groups, growth and reproduction as well as condition factor of Cyprinus carpio (L. 1758) population, which inhabits this dam lake and is of economic importance, was investigated. The age composition of Cyprinus carpio samples were determined to have ranged from I to VIII. Sexual distribution proved to be 41,83 % for females and 43,02 % for males. Minimum fork length of this species was found to be 138 (mm), minimum weight 51 (gr), maximum fork length 525 (mm), and maximum weight 2724 (gr). The highest agespecific number within the population was observed in age group III, whereas the lowest one was in age group VII. Minimum and maximum condition factors were found to be 1,69 in age group VI and 2,26 in age group III, respectively. As far as the seasons are concerned, minimum condition factor was observed 1,84 in July, whereas the maximum one was 2,17 in June. S...

The population comprised 50.74% males, 46.29% females, and 2.97% males+females. In the examined samples, the age of females and males ranged from I to VII and I to VI, respectively. The fork length and weight of females were 14.7-38.0 cm and 40.68-27.0 g, respectively; these values were 16.3-33.7 cm and 57.7-560.0 g, respectively, for males. The age-length and age-weight relationships at time t were calculated by the von Bertalanffy equation for females, and the following results were obtained: Lt = 37.12[1–e–0.36(t–(–0.96))], Wt = 775.6[1–e–0.36(t–(–0.96))]3.27, Lt = 43.59[1–e =1123.2[1–e–0.3356(t–(–0.719))]3.08. The calculated length-weight relationship was W = 0.36L3.27 –0.3356(t–(–0.719))for females and W = 0.03356L for males. The average condition factor was 1.412 for females and 1.284 for males....
