The aim of the study was to design product profiles based on the factors and their levels impacting on the consumption preferences of the apples with Amasya, Isparta, Bayramic apples with the region of origin and foreign origin, and to determine the market shares of each profiles. The main material of the study was the primary data obtained from a face-to-face survey conducted with 600 households consuming apple and residing in the TRA1 region (Erzurum, Erzincan, Bayburt). Conjoint Analysis was used to design the apple profiles maximizing the consumers’ total utilities, and to determine the market share of each profile. Also, Cluster Analysis was applied to segment each apple profile and their market shares according to their income levels. The results of the study highlighted that low-income consumers attributed a great importance to the apple price (41%) and size (32%), but high-income ones to the region of origin (62%) and colour (13%) factors. On the other hand, while the apple profile with 2 number maximized total utility for both low-income group and all consumers, the profile 17 provided the highest satisfaction for high-income segment. The market shares of Amasya apple referred to the region of origin at the profile 2 and 17 for the low and high-income segments were analysed as 40% and 22%, 3% and 35%, respectively. Amasya apple according to other the region of origin maximised not only the consumers’ consumption satisfaction but also the market share at the supply chain.

Peafowl is a common name of three species of the Phasianidae family. It is known as a sacred bird in many Asian countries and India that is the homeland of the peafowl. They live in groups and prefer cultivated areas and forests where they can find more food in nature. They feed on cereal grains, insects, fruits, leaves, seeds. It has a strong structure and adapts very well to different climates. Because of this feature can be produced anywhere in the world. There are commonly known three different types of peafowl. Blue (Indian) Peafowl (Pavo cristatus), Green Peafowl (Pavo muticus) and Congo Peafowl (Afropavo congoensis). The most recognizable species of them is the Indian Peafowl. Peafowl has always been the center of attention with its striking, bright and eye-catching colors on its body and long tail, and it is natural wonders. Therefore, they are especially indispensable members of zoos and ornamental gardens. Although peafowl are usually produced for their beautiful appearance, their meat is also very tasty and beneficial. This article is prepared to give brief information about peafowl.

Büşra Ulu | Bahar Bayhan
The species of the Congridae family belonging to the Anguilliformes order are known as conger eel, and are morphologically similar to the eels which are among the species of the Anguillidae family. In both family species, the dorsal and anal fins are combined with the caudal fin. It is easily distinguished from eel species by the appearance of dorsal fin rays at a closer level to the head. There are 195 species belonging to 30 genus distributed in the world seas belonging to the Congridae family. A third genus of 3 species [Ariosoma balearicum (Delaroche, 1809), Gnathophis mystax (Delaroche, 1809) and Conger conger (Linnaeus, 1758)] shows the distribution of Turkish seas. While the first two species have distributed only Turkey's Aegean and Mediterranean seas, C. conger shows the distribution of all our seas. In this review, where morphological and biological characteristics of European conger are distributed in our country, all studies carried out both in our country and abroad are examined in detail and presented together. With this compilation study, especially biological information about species is missing in our country and attention has been made to contribute to the literature.

Nazife Yiğit Kayhan | İlkay Çorak Öcal
Akrepler, Arachnida sınıfında yer alan zehirli arthropodlardan olup, bilinen en eski karasal eklembacaklılardır ve yaşayan fosiller olarak da tanımlanmaktadırlar. Akrepler kendilerine özgü bir takım özelliklere, özel yapılara sahip olmaları ve zehirlenme vakalarına sebep olmaları nedeniyle çeşitli araştırmalara konu olmuştur. Ancak, akreplere özgü bir duyu organı olan ve tarak organı olarak da bilinen pektin organın yapısı hakkında çok fazla bilgi bulunmamaktadır. Bu çalışmada, Protoiurus kraepelini (von Ubisch, 1922) akrebinin tarak organ yapısı ışık mikroskobu ve taramalı elektron mikroskop (SEM) kullanarak çalışılmış, detaylı morfolojik ve histolojik özellikleri belirlenmiştir. Örnekler Eğirdir (Isparta, Türkiye)’de yapılan arazi çalışmalarında toplanamıştır. P. kraepelini’nin tarak organı diğer akreplerde olduğu gibi bir çift olarak mesosomal ikinci segmentin ventrolateralinde yerleşmiş olup genel mimariye uygun olarak marjinal lamella, median lamella ve pektinal dişler olmak üzere üç kısımdan oluşmaktadır. Aynı zamanda bu yapılar üzerinde yer alan duyusal kılları, pektinal dişler üzerindeki peg sensillanın morfolojileri incelenmiştir. Bu çalışmada, ilk kez P. kraepelini’nin tarak organının histolojisi ortaya konulmuş ve yapı - fonksiyon arasındaki bağlantı uyarınca olası fonksiyonları tartışılmıştır.

Suat Dikel | Fırat Sertaç Tellioğlu
In aquaculture, size grading application is made in order to protect against the disadvantages caused by the length difference between fish. Via this activity, large and small individuals separate each other during the feeding period. In this study designed for this purpose, it was aimed to determine whether the large individuals added to the herd had an effect on the growth performance of small individuals in the culture of Oreochromis niloticus♀ x Oreochromis aureus♂ hybrids. In the experiment, 0 age 1-4 g hybrid juvenile which just complete the juvenile period were stocked as 40 fish / m³ in 500 l fibre tanks placed in a greenhouse and cultured for 75 days. The experimental groups were designed as a graded group (G1) containing 1 g small individual, 1 g + 2 g (G2), 1 g +3 g (G3) and 1 g + 4 g (G4). At the end of the study, it was observed that grading did not positively effect on the growth of tilapia hybrids. In contrast, it was revealed that small individuals (18,60 ± 0,33g) in the G2 group, which included large individuals, grew better than small individuals in the other groups. However, the G2 group reached a better FCR (1.39 ± 0.05) than the other groups. The best economic conversion rate was again achieved in the G2 group (11.12 ± 0.75). As a result, it was observed that the culture practice with individuals of different sizes had a positive effect on the development of hybrid tilapia juvenile, especially when juvenile were stocked as 1+2g stocking composition, as a result of well competition can be established and this situation had a positive effect on the production cost.

Honey is a popular product consumed for its health benefits. It is an effective antimicrobial an antioxidant agent. Globally, palynological and chemical methods are among the means of authenticating honey quality, geographical origin and floral origin. Six honey samples from six Nigerian towns (Abi, Ikom, Lokpanta, Nsukka, Okigwe and Shaki) were subjected to the aforementioned tests. Eighty-six pollen taxa were recorded in all the samples. The richest sample with seventy-three taxa was from Nsukka, followed successively by Okigwe, Lokpanta, Shaki, Ikom and Abi samples with sixty-eight, sixty-seven, sixty-two, fifty-nine and fifty-seven pollen species respectively. The oil palm Elaeis guineensis pollen dominated the samples in different proportions except Shaki honey dominated by Acacia spp., The commonest plant family was Fabaceae (Caesalpinioideae, Mimosoideae, Papilionideae) with twenty-one taxa followed by Euphorbiaceae, Combretaceae, with four representatives and Rubiaceae with three taxa each. The physico-chemical analysis carried out were total moisture, total ash content, colour assessment, percentage of total solids, relative density, acidity, and Fischer’s Test. The samples were found to concur with the international standards for honey.

With this study, it is aimed to reveal the effect of economically sustainable dairy goat breeding in order to provide sufficient income. For this purpose, in Çanakkale Province, which has 234.408 thousand head goats, mostly dairy goat breeding, 30 enterprises were selected through proportional sampling to determine the herd size for technical herd analysis and economic sustainability in family subsistence. The parameters obtained are milk yield (2.1 L), herd size (168.21 heads), number of animals milked (82.54 heads), milk marketing rate (96.75%). 52.30% of milk production costs are variable costs and 47.70% are fixed costs. Feed costs have the highest share in total production costs with 43.88%. In the enterprises, 68.34% of the total gross production value obtained from goat breeding is milk, 27.06% is Productive Fixture Increase and 4.60% is fertilizer income. The cost of 1 L milk in the enterprises was calculated as 1.73 TL (USD 0.36), (the average rate of 1 USD in 2018 is 4.81 TL). 1 L of goat milk price is 3 TL (USD 0.62), (Canakkale, Turkey, sales price, 2018) considering; It has been determined that the enterprises make an average profit of 1.27 TL / L per liter (42%). With the calculated parameters, a profit of 602.27 TL (125.21 Dollars) was obtained from only milk sales in a production period from a dairy goat. A family of four the poverty line, according to the Turkey Statistical Institute 2018 poverty study results are reported on a monthly 6609.000 TL. As a result of the research, the average milk yield is 2.10 L, and as a result of the calculation made considering the average milking time of 225 days and the profit obtained from it, the number of milky goats that will meet the poverty line for a family of four was determined as 131 heads.
