  FATTY ACIDS PROFILES OF RAINBOW TROUT (ONCORHYNCHUS MYKISS WALBAUM, 1792), FED WITH ZEOLITE (CLINOPTILOLITE)

  Danabas, D.

  In this trial, the lipid contents and fatty acid compositions (% of total fatty acids) of rainbow trout fed with four different ratios of clinoptilolite were studied. The fatty acid compositions of fish in groups ranged from 26.81% to 27.93 % saturated fatty acids, 25.35-31.435 % monounsaturated and 32.99-40.185 % polyunsaturated. Among them, those occurring in the highest proportions were oleic acid (C18:1n9, 19.85-22.27 %), palmitic acid (C16:0, 15.60-16.56 %), linoleic acid (C18:2n6, 11.43-18.88 %), cis-4,7,10,13,16,19-docosahexaenoic acid (C22:6n3, 13.36-15.52 %), stearic acid (C18:0, 4.25-4.75 %), palmitoleic acid (C16:1, 3.53-4.59 %), cis-5,8,11,14,17-eicosapentaenoic acid (C20:5 n3, 3.11-3.39 %), and myristic acid (C14:0, 2.56-2.85 %). The findings demonstrated that fatty acid compositions of the groups depend on feed, age, environmental conditions, and effects of feed additives like clinoptilolite. In this respect, it demonstrated that clinoptilolite can be added to fish feeds

  EFFECTS OF ZEOLITE (Clinoptilolite) ON SOME WATER AND GROWTH PARAMETERS OF RAINBOW TROUT (Oncorhynchus mykiss WALBAUM, 1792)

  Danabas, Durali; Altun, Tulay

  The effects of zeolite (Clinoptilolite (CL)) added into pond water, on some water and growth parameters of rainbow trout (Oncorhynchus mykiss Walbaum, 1792), were investigated, in the present study. CL was added into water by 0 (control), 1, 2, 3 mg l(-1) rates and carried out in 100 days. The results of the study showed that average body weights of fish in group were respectively, 128.242 +/- 4.748 g, 126.623 +/- 5.545 g, 126.349 +/- 0.339 g and 126.556 +/- 7.663 g and average total lengths were 21.870 +/- 0.355 cm, 21.340 +/- 0.341 cm, 21.783 +/- 0.255 cm and 21.191 +/- 0.193 cm. However, there was no statistical difference among groups for all parameters (P>0.05). At the end of the study, there was no statistical difference among groups for water parameters (P>0.05), but an obvious decreasing was observed in nitrate rates during study and in ammonium and nitrite rates during only first period.
