Kombucha is a beverage prepared from fermented traditionally-flavored black or green tea (Camellia sinensis L.) with symbiotic culture of bacteria and yeast (SCOBY). In this study, the changes in the physicochemical, bioactive components, microbial quality and sensory properties of black tea kombucha and different proportions of purple basil (Ocimum basilicum L.) kombucha after fermentation were evaluated. While the pH values decreased during storage, the total acidity value increased. Purple basil had higher total phenolic content at all storage times than the other samples. At the end of the study, it was concluded that the total amount of phenolic compounds and flavonoids in purple basil was highly conserved compared to the other samples. Antioxidant values on the 30th day determined highest DPPH (radical scavenging activity) (64.19%) and CUPCAC (cupric reducing antioxidant capacity) (41.48%) in the purple basil kombucha beverage. When the color values were examined, it was found that there were statistically significant differences in the overall storage process in all samples. There was no significant change inconsistency, smell, taste and general acceptance with the storage process. As a result, 30-day storage period was found to be more successful and favorable for 100% purple basil kombucha tea.

Grazing activities of indigenous sheep breed of the Turkish breed Karakaş and Koçeri which were transhumance flocks were investigated in a typical unimproved mountainous pasture in the East of Turkey. Data were collected from two different flocks on main daily activities (grazing, resting, moving or standing) every fifteen minutes. The characteristics of the pastures around the routes were assessed according to CORINE Land Cover classification system. Standing was a residual activity in both study paths. The animals concentrated their activity mostly on grazing while resting and moving occurred in specific times during the whole grazing period. Once the animals were heading back to their main settlement areas to be milked, grazing activity have been increased. Further studies on grazing behavior and changes in land cover will help to adjust the management strategies to the available natural resources.

The aim of this study is to determine the consumption habits of aquatic products in Ardahan province and its districts. The study carried out between 2014 and 2015 was prepared face to face with the consumers by using a questionnaire prepared to measure the consumption habits of aquatic products. The research material consisted of data collected from 302 people by face to face survey method. When the demographic data were analysed according to the results of the study; 73.84% of the respondents were native to Ardahan and 26.15% were immigrants, 38.08% were female, 61.92% were male, the average age was 32.50 and the average monthly income was 1862.80 TL. According to the findings of the study, per capita annual fish consumption is 39 kg and per capita monthly fish consumption is 3.25 kg. The most preferred species of freshwater fish was trout (75.22%), while anchovy was found in marine fish (48.57%). While 21.98% of the participants consume fish, 18.73% chicken, 17.62% veal, 13.52% goose, 13.34% sheep, 6.67% goat meat and 4.19% turkey meat, only 1.71% prefer aquatic species such as mussels and shrimps. The important reason why fish is preferred is being healthy with 45.03%. The other most consumed aquatic products is mussel with 11.92%. It was determined that 76.49% of the consumers did not consume aquatic products other than fish. As a result, it is determined that although there is no coastline of Ardahan and the socio-economic level of the people is not high, the consumption of fish is high. The people of the region who deal with cattle as a source of livelihood prefer to consume aquatic products. In this respect, Ardahan is at the level that can be an example to Turkey.

Today’s consumers prefer foods with high nutritional value, functional properties and long shelf life. Particularly, interest in fresh fruits and vegetables, which are ready for consumption due to their healthy and nutritious nature, is increasing. However, biological activities such as respiration and transpiration cause loss of water and soluble substances in fruits and vegetables and change the gas concentration in the environment during storage and this situation greatly affects critical quality parameters such as mass loss, nutritional value and shelf life. Minimal processing, such as peeling, cutting or shredding increases the surface area of fresh fruits and vegetables, reduces the shelf life by triggering a variety of enzymatic reactions. The edible film coating is a novel packaging method that is natural, environmental friendly, economic and easily applicable. This innovative technique can be used to produce a product that is closest to fresh fruits and vegetables, maintain the desired quality characteristics, control microbiological spoilage and extend the shelf life. In addition, the use of plant-based materials in film coating applied to minimally processed fruits and vegetables attracts the consumers and increases the confidence in products. In this review, the information about the current applications of edible coating to the minimally processed fruits and vegetables and the effect of this application on some physical, chemical, sensory and microbial changes occurring in the products during the storage period has been presented.

This study aims to fully controlled production of european catfish (Silurus glanis) and to increase fertilization and survival rates using different solutions and methods, enrichment of natural stocks with the obtained larvae and to provide participation as a new species in addition to species cultivated in Turkey. The study was carried out in Gürle Trout Farm in Manisa province. Eggs and sperm, that had been obtained from the broodstock, exposed to various fertilization methods and the fertilized eggs were put in the zuger jars and made triplicate trials. As a result, in this study, under the light of the findings obtained from different fish that was captured in different times and from two different regions; eggs that were treated with the urea-salt solution fertilization, eying and survival rates were higher than only salt solution application. Urea-salt solution for 10 minutes and the salt solution for 10 minutes were more successful. In addition, the time problem of working with living materials has become one of the biggest obstacles to this work. It is imperative that the reproductive cycle occurs once a year and in case of failure, it is needed to wait for the next cycle. In this context, it was not possible to tolerate the problems experienced in egg-taking, fertilization and survival activities in the last attempt. Therefore, the project had to be terminated here.

In this study, the age, growth, and gonado-somatic index (GSI) of the Red mullet (Mullus barbatus ponticus Essipov, 1927) from the Eastern Black Sea coast of Turkey were examined. A total of 1466 M. barbatus ponticus were sampled between September 2010 and August 2011 from trammel net landings in Rize. The total length of Red mullet ranged from 7.42 cm to 17.80 cm and weight ranged from 9.59 g to 50.93 g, regardless of the sex. The sex ratio (♂/♀) was 0.46, with almost twice more females than males. The growth performance of M. barbatus ponticus in the study area is similar to that of the western populations of the same sub-species. A closed season of at least three months (from May to July) banning the use of even the stationary fishing gear will be beneficial for the sustainable stock of management of M. barbatus ponticus in the Black Sea.

The combinations of organic liquid fertilizer material obtained from sea lettuce (Ulva lactuca) and different concentrations of zeolite were applied to the cucumber (Cucumis sativus) plant in six treatments with three replicates each. The combinations of the experimental groups were as follows; control group, G1 group 180 g Z (Zeolite), G2 group 90 g Z + 1140 ml Liquid Fertilizer (LF), G3 group 180 g Z + 620 ml LF, G4 group 270 g Z + 310 ml LF, G5 group 620 ml LF. Except the control group, all zeolites were applied with the first dose of liquid fertilizer, and other liquid fertilizer doses were given in three periods, after germination, flowering and yield. While the lowest germination rate was in control group, the highest rate was in group with 60 g zeolite. While the lowest seedling weight was observed in group with 90 g zeolite + 1140 ml liquid fertilizer, the highest rate was in group with 180 g zeolite + 620 ml liquid fertilizer. While the highest cucumber weight was observed in group with 270 g zeolite + 310 ml liquid fertilizer, the lowest was in group with 620 ml liquid fertilizer. Therefore, it may be said that zeolite has positive effect on germination. On the other hand, liquid fertilizer and zeolite combinations may have positive effects on the weight of the cucumber seedling and yield.
