As it is common in tropical and temperate zones, mullet species constitute the most important fish species caught along the coast and estuaries of Turkey. In terms of ecology, tourism and and fish productivity (52 kg/ha), Koycegiz-Dalyan Lagoon Ecosystem (KDLES) is the most important lagoon, with a 5500 ha surface area, is the Mediterranean Coast of Turkey. In the dalyan (barrier fish trap) systems; approximately 225 tons (80-405 tons) of mullets are caught to obtain 5 tons of dried fish eggs per year. Seventy percent of fish production in the lagoon is composed of mullets. The mullet samples were collected monthly between October 1992 and September 1994 from eight stations (one of them is a marine station) by trammel nets. The ages were determined using by scales anda ge composition varied form 0 to 6 ages. Species composition of 1159 sampled individuals were proportionally determined as Mugil cephalus 45%, Liza aurata 35%, Liza saliens 14%, Liza ramada 12%, Chelon labrasus 6%. The growth performance indices calculated from von Bertalanffy growth parameters using by all individuals for the M. cephalus, L. aurata, L. saliens, L. ramada and C. labrasus were determined as 2.957, 2.866, 2.692 and 2.719, respectively. The highest growth performance index was calculated for M. cephalus. The growth performance indeces of mullet species in Köyceğiz-Dalyan Lagoon Ecosystem were found around the world averages.

The present research was carried out to determine the effects of the addition of cardamom powder at different levels (0, 1, 2, 3 or 4 g/kg) to diet on performance, egg quality, and serum parameters in laying quails. In the experiment, a total of 120 laying quails at the age of 20 weeks were randomly distributed to 5 treatment groups with 6 subgroups (4 quails each). Quails were fed with experimental diets for 10 weeks. In the experiment, the feed intake of quails significantly increased with the supplementation of cardamom powder at the level of 3 g/kg to the diet, while other performance parameters were not affected. Eggshell thickness advanced with the addition of 1 g/kg cardamom powder to diet. Egg yolk L* value increased at the level of 4 g/kg, but a* value decreased with the addition of cardamom powder. Other egg quality parameters were not affected by the addition of cardamom powder to the diet. In addition, the supplementation of cardamom powder to the diet significantly reduced serum cholesterol levels of quails. According to the results obtained from the experiment, the addition of cardamom powder at the level of 3 g/kg to the diet increased the feed intake of quails, while the supplementation of 1 g/kg was effective in improving the eggshell quality and serum cholesterol level.

In this study, it was aimed to report some traits of Gökçeada goats, which raised under the natural conditions of Gökçeada, with respect to their protection within the scope of genetic resources. In this respect the information obtained from the goats supplied from the Island and reared in a semi-intensive system at Çanakkale Onsekiz Mart University and also the information obtained from the literature were collected and the biological and zootechnical identifications of the Gökçeada goat were performed. Gökçeada goats, which are predominantly black, have yellow or red blazes on both sides of their heads including their eyes. It was seen that Gökçeada goats had similar body measurements and lower live weights as compared to those of the same species on the mainland. The birth weight and the mature live weight of Gökçeada goats were found as 2.55 kg and 38 kg, respectively, whereas their mean kid yield per goat at birth was determined as 1.6 to 1.8 kids. Individuals with a milk yield of 591 kg were striking in the Gökçeada genotype, in which the mean lactation length and the mean lactation milk yield were determined as 251 to 259 days and 227 to 245 kg, respectively. Its milk fat (4.92-5.75%) and milk protein (3.29%) resembled those of our other native breeds. It is necessary to reveal, with more elaborate studies, the potential for Gökçeada goat cheese that is greatly demanded on the Island. It was determined that the Gökçeada kids, which were considered as dairy kids, had some small but nonfat carcass and that their meat was soft and of a light color and had a slight smell. One should be careful about the adaptation of the Gökçeada genotype, which successfully maintains itself under the island conditions and which is the source of income for producers, to intensive and extensive goat production systems.

The objective of this study was to evaluate the physical, bioactive and textural properties of oleaster fruits grown in different locations of Turkey. The oleaster fruits were obtained from Aksaray, Niğde and İzmir cities and their crumb and crust parts were analyzed individually and freshly. In terms of color, the crust and crumb of oleaster fruits from İzmir had the darkest color with L* values of 46.81 ± 4.06 and 78.91 ± 4.97 among all tested fruits from different locations, respectively. Total of phenolic (TP), flavonoid (TF) and tannin (TT) content (C) and as well antioxidant activities (AA) of oleaster fruits were determined for the crust and crumb of oleaster fruits. The highest TPC (22.30±1.75 mg gallic acid equivalent/g DM), TFC (16.24±1.49 mg catechin equivalent/g DM) and AA (14.05±0.55 μmol trolox equivalent/g DM) by DPPH were found in the crust of Aksaray oleaster fruits. In addition, the crumb of Aksaray oleaster fruit had the highest TPC (16.44±1.67 mg gallic acid equivalent/g DM) among the crumbs of oleaster fruits from different locations. Furthermore, there was no significant difference among the texture of crust and crumb of oleaster fruits obtained from different locations. Results showed the growing location of oleaster fruits had a significant influence on the physical and bioactive properties of fruits. Also, this study indicated that oleaster fruits were rich in bioactive compounds; therefore, they could be incorporated into foods to design functional foods.

The tadpoles of four amphibian species, namely the Marsh Frog (Pelophylax ridibundus), the Iranian Long-Legged Frog (Rana macrocnemis), the Caucasian Parsley Frog (Pelodytes caucasicus) and the Variable Green Toad (Bufotes variabilis), were exposed to acute concentrations (0 to 500 mg/L) of ammonium nitrate to assess the lethal effects (larval growth, abnormalities, mortality, and LC50 values). Eggs of each species were obtained from clean and polluted habitats in the same region and the tadpoles for experiments were provided from those eggs in the laboratory conditions. Although there was some variability between different populations of the same species or between different species in the observed effects, acute levels of ammonium nitrate caused decreased growth rate and increased abnormalities and mortality in general. Among the 4 amphibian species, the Variable Green Toad was the most damaged one in terms of growth reduction (on average 77-83%), and abnormality rates, and the most damaged one in terms of mortality rates was the Marsh Frog (on average 61-72%). Additionally, the species with the lowest concentration of ammonium nitrate, which killed half of its population, was the Marsh Frog. LC50 values for two populations of Marsh Frog were 37 and 59 mg/L. As a result of our research, it was determined that the acute fertilizer levels caused by agricultural activities in the region had very important harmful effects for all the species we examined. In this context, it can be said that very important environmental and biodiversity problems may occur if certain precautions are not taken regarding the use of the fertilizers and if the awareness of the farmers using these fertilizers cannot be raised.

The study aims at determining the physicochemical, proximate composition and the total viable count of Staphylococcus aureus in ‘Nono’ and yoghurt samples in Kaduna, Nigeria.Three hundred and eighty-four (384) fermented milk samples (Nono and yoghurt) were obtained from different selling points and were evaluated for the occurrence of S. aureus. The physicochemical and proximate analyses (pH, total titratable acidity, moisture content, ash content, protein content, and fat content) were determined. The results of the analyses showed that Nono had pH range of 3.56-3.61, total titratable acidity: 0.71-1.72, moisture content: 82.23-83.87%, ash content: 0.30-0.31%, crude protein content: 1.50-1.61%, crude fat content: 0.35-0.38 %. For yoghurt, the pH ranged from 3.76 -3.82, total titratable acidity: 1.10 -1.15, moisture content: 77.76-80.06%, ash content: 0.68- 0.70%, crude protein content: 3.40-3.45% and crude fat content: 1.76-1.79% from all the study areas. One hundred and four of the total samples were contaminated with S. aureus. Out of the 104 isolates of S. aureus that were isolated and identified, 88 were coagulase positive S.aureus. The Microgen Staph ID kit (Oxoid) was used to further confirm the characteristics of the 60 isolates of the coagulase positive S. aureus. The kit confirmed 43 isolates as S. aureus, the results indicated the presence of S. aureus in the milk samples which is of public health importance, as this can contribute to food-borne intoxication which can lead to food poisoning. There is a need for proper pasteurisation of raw milk to help eradicate S. aureus infection before human consumption.

This study established an efficient in vitro callus formation and plant regeneration protocol for a prevıously reported Cu accumulator, Brassica nigra, black mustard collected from Diyarbakir (Station site). Node explants from 10-day old mature plants were used for callus formation and shoot regeneration. The highest callus formation frequency (100%) was observed on Murasige Skoog (MS) medium containing 0.1 mg/L Benzylaminopurine (BAP) + 0.5 mg/L Naphthylacetic acid (NAA) (MS 2), 0.6 mg/L BAP + 0.2 mg/L NAA (MS 7), the highest shoot regeneration frequency (100%) was achieved on MS medium containing 0.6 mg/L BAP + 0.05 mg/L Indole butyric acid (IBA) (MS 8), 0.2 mg/L IBA + 0.2 mg/L NAA (MS 10) and the highest number of shoots per explant (3,25) was obtained on MS medium supplemented 0.6 mg/L BAP + 0.05 mg/L IBA (MS 8). After root, stem, and leaf formation from explants in MS medium, these plants were transferred to soil and grown in the plant growth room for one month. A dependable and effective shoot regeneration procedure was developed, laying the groundwork for genetic transformation in Brassica nigra.
