  The Effects of Probiotic-Prebiotic on the Biomass and Protein Content of Spirulina platensis in Different Temperatures and Illuminations

  Seyhaneyıldız Can, Şafak; Seyhaneyıldız, Elif; Dörücü, Mustafa

  The blue-green algae Spirulina platensis Geitler 1925 has been used by people since ancient times due to its high protein content. This study was conducted to determine the effect of a Probiotic-Prebiotic (P-P) product, which contains Bifidobacterium infantis, Bifidobacterium thermophilum, Leuconostoc mesenteroides as probiotic bacteria, and beta-glucan and oligosaccharide as a prebiotic mixture on S. platensis. In the study, four groups were one of which was a control. In this study, we investigated whether the P-P product contributed to the biomass development and protein production of S. platensis under different temperatures and lighting conditions. In terms of biomass, the P-P product gave different responses at different temperatures and light intensities, but its results were positive in all groups in terms of protein ratio. The most positive effect on biomass and protein content was in the group where 0.1 ml/L P-P product was added, at 40°C and 3200 lux with 68.71% protein content and an average OD of 0.727.

  Potential Role of Zeolite on Improvement of Aquaculture Sector

  Danabaş, Durali; Dörücü, Mustafa

  Aquaculture, which is very important in many regions of the world, attracts attention as the fastest\rgrowing sector in the livestock sector in our country. The share of our country's aquaculture\rproduction in the production of total aquatic products is increasing day by day. Studies have been\rcarried out to solve feed problems and importance has been attached to additives that reduce cost\rand feed conversion ratio (FCR) to contribute to feed quality. Zeolites came to the forefront as feed\radditives. Due to the gap between 20 and 50 % in the structure, the molecules can be taken into the\rstructures and they are named as molecular sieves. Zeolites are used for purposes such as controlling\rthe pollution in pools in the aquaculture sector, increasing the growth parameters of the fish by\rincubation, fish transport and removal of nitrogen compounds from aquarium water, increasing\rambient oxygen in aquarium and fish transport, and as feed additive. In Turkey, billions of tons of\rzeolite have been detected and clinoptilolite type zeolite is found mostly in the beds of AnkaraPolatlı-Mülk-Oğlakçı Region and Bigadiç, Şaphane, Gediz, Emet and Gördes Districts. We believe\rthat the use of zeolites produced in Turkey as a local and natural product as feed additive substance\rin the aquaculture industry in the aquaculture sector will contribute to the production of lower cost\rfish as well as contribute to the development of 2 different sectors (aquaculture and mining) in\rinteraction with each other.

  EFFECTS OF HEAVY METAL ON Tetraselmis chuii

  Kutlu, Banu; Dorucu, Mustafa

  We determined the toxic effects of seven metals. copper (Cu), manganese (Mn). zinc (Zn), cobalt (Co). molybdate (Mo), lead (Pb), and cadmium (Cd) on the microalgae Tefraselmis chuii (Butcher, 1959). We exposed 50 mL of cultivated microalgae (f/2 Gaillard) in the exponential growth phase. with three replicates, to concentrations of 0 (control). 0.1, 1.0, 5.0, 10, 25. and 50 g L of each metal for 72 hours. The cellular count was recorded daily to evaluate any potential lethal effects. An increase in cellular density was seen in the control treatment. All treatments exposed to metals showed a logarithmic increase in cell density within 48 hours, with a cellular decrease that became evident later on. This study result with an insignificant decrease at low concentrations of Cd, Pb, and Cu at 24 hour was probably attributed to their use as micronutrients at these low concentrations. The most lethal effect was observed with Cd treatment, which killed 50% of the microalgae population at a concentration of 0.62 mu g L-1. In this study, this concentration was three times lower than that of lead and mercury. while being ten times lower than that of cobalt and molybdate. To elucidate the adverse effects on seawater environments, the microalgae Tetraselmis chuii is recommended as a model species.

  Gölova Baraj Gölü (Sivas)’nde Yaşayan Pullu Sazan (Cyprinus carpio Linnaeus, 1758)’ın Bazı Büyüme Özellikleri ve Et Veriminin İncelenmesi

  Yüngül, Mücahit; Gokhan, Haci Bayram; Dörücü, Mustafa

  Bu çalışmada, Temmuz 2017 - Mart 2018 tarihleri arasında Gölova Baraj Gölü’nden yakalanan 82 adet pullu sazan (Cyprinus carpio Linnaeus, 1758)’ın cinsiyet ve yaş gruplarına göre bazı büyüme özellikleri ile et verimliliği araştırılmıştır. Örneklerin % 32.93’ünü dişi, % 67.07’sini erkek bireyler oluşturmuştur. Dişi ve erkek bireyler II-V arası yaşlarda tespit edilmiştir. Ortalama total boy ve ağırlığın dişilerde 40.99±1.07 cm ve 1001.27±82.97 g; erkeklerde 37.27±0.41 cm ve 734.34±30.69 g; tüm bireylerde 38.49±0.49 cm ve 822.23±36.65 g olduğu saptanmıştır. Tüm örnekler için boy-ağırlık ilişkisi W=0.0151TL2.9743 (R2=0.8796) ve ortalama kondisyon faktörü 1.385±0.018 olarak belirlenmiştir. C. carpio’da et verimliliği ile çeşitli vücut kısımları arasındaki ilişkiler incelendiğinde; fileto ve karkas ağırlıklarının ortalama et verimleri sırasıyla dişilerde % 47.59±0.71 ve % 59.19±0.82; erkeklerde % 49.80±0.32 ve % 60.67±0.34; tüm bireylerde % 49.07±0.34 ve % 60.18±0.36 olarak saptanmıştır. Tüketilmeyen vücut kısımlarından iç organ, baş, yüzgeç, deri ve kemik ağırlıklarının vücut ağırlığına göre ortalama oranları da tüm bireyler için sırasıyla % 12.98±0.39, % 22.32±0.23, % 4.51±0.79, % 8.49±0.25 ve % 2.63±0.04 olarak belirlenmiştir.

  The effect of water parameters and dissolved minerals on the hematological parameters of during breeding period catfish (Silurus glanis)

  Küçükgül, Azime; Yüngül, Mücahit; Kahraman, Zuhal; Dörücü, Mustafa

  In this study, the blood parameters of catfish (Silurus glanis Linnaeus, 1758) inhabiting Celik Lake (Adiyaman, Turkey) were investigated. The study was conducted between April 2013 and October 2013. After obtaining a blood sample from each catfish has been hematologically analyzed. Then, the water temperature, dissolved oxygen, pH, calcium, magnesium and nitrate values were determined at before breeding (April), breeding period (June-July) and after breeding of fish (October) and the impacts of these data on hematological values were investigated. According to this study, it was observed that the hematological values obtained at before breeding period, breeding and after the breeding period were affected by the water quality parameters.
