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.

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 most suitable mantle part and host mussel species for pearl sac formation were determined. A total of 400 mussels, consisting of four different types (Unio terminalis, Potamida littoralis, Leguminaia wheatleyi and Anodonta pseudodopsis) were used. The average dorso-ventral lengths of the mussels were respectively; 7.89±0.25; 7.28±0.38; 10.68±0.27 and 11.14±0.34 cm. Mantle tissue slices in the size of 3×3 mm obtained from the pallial edge of mantle tissue were used as grafts. Two different mantle sections were identified for graft implantation, one being the mantle cavity and the other was incisions on the mantle tissue. At the end of the three-month pearl culture, the mantle cavity section was identified as the best graft implant site. U. terminalis was determined as the most successful species in terms of survival rate and pearl formation. P. littoralis was the second successful species and L. wheatleyi was the lowest among the species. This study is a guide for long-term pearl production on nacre thickness and quality which are considered important in pearl production.

In this study, electric yellow cichlid were (Labidochromis caeruleus) exposed to acute cadmium (Cd) concentrations (0, 50, 60, 70, 80 mg l-1) for 72 h, and chronic Cd concentrations (0.00, 0.25, 0.50, 1.00, 2.00 mg l-1) for 20 d to examine histological alternation. In addition to the recovery was detected after 10 d. After chronic trial, rest of the fish were exposed to just water not containing cadmium for 10 day for recovery. Gills, liver, muscle, and spleen samples were collected from randomly selected fish. The tissue samples prepared with standard techniques for haematoxylin and eosin (H&E). Cadmium depending on concentrations increase caused severe disorders on fish. After acute exposure, several changes were detected such as edema, hyperplasia, breakdown in epithelial tissues of gills; vacuolation and necrosis in liver; increase of hemosterin clustering and necrosis in spleen. After chronic exposure, some symptoms were also found such as edema, aneurysm, degermation of secondary lamellae in gills; degeneration and necrosis in liver; degeneration and granulomas in spleen. Additionally, after recovery of chronic Cd exposure some of the same symptoms were observed such as edema, hyperplasia and aneurysm in gills; vacuolar degeneration and necrosis in liver; granulomas and degeneration in spleen.

In this study, the effect of different concentrations of smoke solution derived from sage (Salvia officinalis L.) on root and shoot growth of grass pea (Lathyrus sativus L.) was investigated in pots, in petri dishes (in vivo) and in vitro conditions. Smoke solution was obtained from hookah method and different concentrations (25%, 50%, 75%, 100%) were prepared by diluting the stock solution with distilled water and, distilled water was used as control. Solutions were used starting water of petri and perlite media and to prepare MS0 for in vitro condition. Nodal segments of grass pea seedlings as explants were cultured on MS0 medium in vitro. Plant nutrients, antioxidants, organic or inorganic chemicals, and plant growth regulators are commonly used for plant development both in vivo and in vitro. However, their use has risks in terms of economic costs as well as nature, environment and human health. Therefore, use of naturally derived chemicals in these applications has great advantages. Observations for in vivo conditions were determinate after 7 days from sowing and 15 days after in vitro culture. The longest root length (6.089 cm) was determined in 75% smoke solution of sage and, while the longest shoot length (3.026 cm) was obtained from 100% smoke solution of sage on petri media. In perlite media, the highest root and shoot length were observed in pure water (control). İn vitro conditions, although shoot formation was above 85% in all applications, root formation was under 33%. The shortest shoot length was obtained from smoke solutions of 100% (5.02 cm), the longest shoot length was obtained from 25% and 75% concentrations of smoke solution, respectively 8.35 and 8.94 cm.

The growth of fish in intensive fish farming is carried out completely by the feeds supplied from externally. Different ingredients are used in feed production. The nutritional content of these ingredients is checked when purchased or brought to the factory. These ingredients are then stored until feed production. Storage duration and storage temperatures directly affect the freshness criteria of feed ingredient materials. Especially when high-energy ingredients with high levels of fat are stored in poor storage conditions, the fats in the ingredients are oxidized, therefore the peroxide number increases and the ingredient becomes bitter. Oxidation not only destroys the lipids in fish feeds but also vitamins. Slow growth, poor feed evaluation, color darkening, lethargy and deaths have been reported in fish fed with diets that are oxidized and inadequate in vitamin E. In this study, oxidation levels of fish feed ingredients were determined due to different storage conditions. Generally, the number of peroxides increased due to the increase in storage time and temperature, depending on the type of raw materials and oil content.
