Abstract Comparative analysis of morphometric characters of small-scaled scorpionfish from the Black Sea (near the southern coast of the Crimea) and from the eastern part of the Adriatic Sea showed significant differences in males and females on thirteen plastic and three meristic characters. These differences may be due to unequal abiotic and biotic habitat conditions, and refer about the geographical variability of the species, indicating the presence of two different populations in the study area.

AbstractNarrow-clawed crayfish, Astacus leptodactylus is a native European freshwater crayfish species, also distributed in Croatian freshwater systems belonging to the Black Sea drainage. Its taxonomical status is still in the process of change and discussion, and the data on morphological, molecular, ecological and zoogeographical characteristics of this species are scarce. Therefore, comparative analyses of morphological characteristics were applied with the aim to contribute to the knowledge on the morphometrical and meristical characteristics of A. leptodactylus. Recent research proved that measurements of a large number of morphometrical characteristics, in combination with multivariate statistical analysis, could provide a good instrument for identification and differentiation between populations. In this research altogether 143 animals were analysed (121 from two Croatian populations and 22 from Armenia). 22 morphometrical characteristics and 4 meristical characteristics, per crayfish, were measured. It was found that males and females differ between populations in measured meristical and morphometrical characteristics. None of recorded meristical characteristics proved itself to be reliable characteristic for distinguishing populations. From measured morphometrical characteristics the most discriminant characteristics for separating males from different populations were those describing carapace shape and for females those that describe shape of the claws.

The abundance of Capillaria obsignata Madsen, 1945, the causative agent of chicken capillariasis, was studied in the central region of Ukraine. Differential morphometric characters are determined for adult males and females of C. obsignata. The species-specific variability of its morphological parameters is characterized. New data is received on the meristic characters of C. obsignata eggs extracted from different substrates. The stages of embryonic development are determined in laboratory cultures of these nematodes, taking into account their meristic and morphological changes. Capillaria obsignata parasites are very common at the poultry farms of Poltava and Kyiv regions of Ukraine. Their abundance index is 3.4, and the intensity of infection varies from 3 to 317 specimens. Differential morphometric species-specific characters of adult C. obsignata males are the shape and size of the pseudobursa, spicule, spicule sheath. Adult females of the species can be identified by the shape and size of the vulva, the distance from the esophagus end to the vulva, and the length of the vagina. The meristic characters of nematode eggs, though typical for the species, may change depending on the sampled substrate. The parasite’s embryonic development involves five morphologically and meristically different stages. The invasive larvae of this species developed in the eggs before the 12th day of culturing in laboratory conditions at 25 °С. The invasive larvae’s viability was 90.3 ± 1.5%.

Persilangan antara dua populasi yang berbeda secara genetik lazimnya menghasilkan kombinasi genetik baru. Penelitian ini dilakukan untuk mengevaluasi karakteristik fenotipe dan genotipe ikan gurami strain Galunggung Hitam, Galunggung Putih, dan Hibridanya. Perkawinan dalam galur (GP X GP dan GH X GH) dan persilangan dua arah antara betina GH dan jantan GP (GH X GP), dan resiprokalnya (GP X GH) telah dilakukan di BPBIGN Singaparna. Fenotipe dianalisis berdasarkan metode truss morfometrik dan meristik, sedangkan karakteristik genotipe diamati menggunakan metode PCR-RAPD. Hasil analisis menunjukkan berdasarkan 21 karakter truss morfometrik, centroid hibrida GH X GP lebih tinggi dari centroid ketiga populasi lainnya pada PC-1 yang dicirikan oleh karakter B3, B4, B5, A3, A4, dan A6, dan bersifat intermediate pada PC-2, PC-3, dan PC-4. Berdasarkan delapan karakter meristik, centroid hibrida GH X GP lebih tinggi dari kedua tetua dan hibrida GP X GH pada PC-1 yang dicirikan oleh karakter SPR dan SDA, lebih rendah dari kedua tetua, tetapi lebih tinggi dari populasi GP X GH pada PC-2, dan lebih rendah dari ketiga populasi lainnya pada PC-3 dan PC-4. Polimorfisme dan heterozigositas pada populasi hibrida GH X GP dan GP X GH lebih tinggi daripada kedua tetuanya GH X GH dan GP X GP. Hibridisasi yang dilakukan meningkatkan variasi genetik yang dapat berguna dalam peningkatan produktivitas budidaya.Hybridization between two genetically different populations is expected to generate a population carrying new genetic combinations which may be expressed in both phenotypes and genotypes. This study was carried out to explore the phenotype and genotype characteristics of reciprocal hybrids of goramy of Galunggung black (GH) and Galunggung white (GP) with respect to their parental lines. Matings within the same line producing GP X GP and GH X GH, and reciprocal mating producing hybrids GH X GP and GP X GH, were conducted at BPBIGN Singaparna. Samples representing the four populations were analyzed for their morphology using truss morphometric and meristic methods, while genotypes were analyzed using PCR-RAPD method. The results showed that based on the 21 morphometric characters, the centroid of hybrid GH X GP was higher than those of the other three populations at PC-1, which was marked by the characters B3, B4, B5,A3, A4, and A6, and was intermediate at PC-2, PC-3, and PC-4. Based on the eight meristic characters, the centroid of GH X GP was also higher than those of their parents and hybrids GP X GH at PC-1, which was marked by the characters SPR and SDA, lower than those of their parents but higher than that of hybrid GP X GH at PC-2, and lower than those of the other three populations at PC-3 and PC-4. The genetic diversities in terms of polymorphism and heterozygosity levels in hybrids GH X GP and GP X GH were higher than those found in the pure-line (GH X GH and GP X GP). Hybridization conducted in this study had resulted in the enhancement of genetic variations which could be useful in increasing aquaculture productivity.

Great Prosperity

Everyone who has the slightest acquaintance with the Crimea at the present time, and especially with the economic conditions which prevail there, is thoroughly aware of its intimate connexion, both economic and social, with the southern coast of the Black Sea—with Samsun, Eregli, Sinope, Kerasund, Trebizond and other towns. Great masses of workmen from these parts flood the cities of the Crimea. Practically all shipments by sea in vessels of small displacement are carried out by the owners of feluccas, who hail from the municipal centres of ancient Pontus and from the neighbouring sea-towns of what was once Bithynia. A glance at the map is sufficient to show that there is no casual connexion here; the close interconnexion between the shores of the Crimea and the southern coast of the Black Sea, which is almost visible with the naked eye from the southernmost point of the Crimea, has been brought about by the natural conditions of the locality. The decline in the prosperity of the southern Turkish coast of the Black Sea and the great prosperity of the Crimea in the years immediately preceding the war were the chief reasons why the Crimea played the part of employer, and the sea towns of the southern coast the part of supplier of labour. They provided as well the necessary tonnage for coastwise shipping, mostly in the shape of small sailing vessels. Such could not always be the case, nor indeed have such conditions continuously prevailed, although, generally speaking, similar relations must needs be established quite independent of the fortune assigned by history to the districts with which we are now dealing.

Pennahia anea is among of the demersal fish landed at Asemdoyong Fish Auction Centre, Pemalang. P. anea doesn't show sexual dimorphism, so that other characters are needed to differentiate male and female individuals, i.e. truss morphometric and meristic characters. Previous studies have shown that truss morphometric and meristic can differentiate between male and female individuals. This study aims to describe the morphometric and meristic truss characters and determine the truss morphometrically and meristic characters that distinguish between males and females of Pennahia anea. The research used a survey method with a purposive random sampling technique. Male and female individuals of P. anea were examined based on their meristic and truss morphometric characters. The data were analyzed statistically using Mann Whitney non-parametric test. The result proved that male and female were significantly different in seven out of the 31 truss distances. Male individuals had a larger size than female individuals in three truss distances. In contrast, the male had a smaller size than the female individuals in four out of seven truss distances that distinguish both sexualities. The soft fin radius of the ventral fin was significantly different between male and female of P. anea. It could be concluded that male and female individuals of Pennahia anea have different truss distances and meristic characters with seven truss distances and one meristic character are different

Abstract Sex differences and the ability to determine the sex of Scorpaena porcus (Linnaeus, 1758) on morphological characters were studied in the population inhabiting coastal waters of the Black Sea near the southern coast of Crimea. These differences were revealed in size (females are larger than males) and in proportions of the body. It is found that variation of the absolute and relative values in plastic characters is higher in females compared with males. It is shown that in 92 % of individuals belonging to S. porcus we can determine the sex using morphological characters with a probability of 99.9-100 %.

The relationship between morphometric measurements (16) and meristic characters (6) was examined in 460 specimens of the European hake (225 females, 210 males and 25 immature ones) caught in the central Adriatic Sea. Morphological difference between males and females was not marked. Biometric analyses of the morphometric and meristic characteristics indicated a homogenous morphology stock of M. merluccius in the central Adriatic Sea. Changes in some morphometric characteristics obtained in conjunction with an increase in body length showed that smaller specimens have a longer head, anal and ventral fin than adult specimens. The negative correlation recorded for the maximum and minimum body depth indicated that the body becomes progressively elongated. The meristic characteristics of the European hake from different Mediterranean and NE Atlantic areas are mostly in agreement with the data in our study.

In contrast to the hydrological and hydrochemical zoning, hydrographic and water management zoning of Ukraine (2016) was created on a basin basis, taking into account the boundaries of river basins, and not physiographic zoning. The main function of hydrographic and water management zoning is water management. Primary is hydrographic zoning, and water management - based on it. The description of modern hydrographic zoning of the territory of Ukraine, approved in 2016 by the Verkhovna Rada of Ukraine and included in the Water Code of Ukraine is given. Hydrographic zoning is carried out for the development and implementation of river basin management plans. On the territory of Ukraine nine areas of river basins are allocated: Dnipro; Dnister; Danube; Southern Bug; Don; Vistula; rivers of the Crimea; rivers of the Black Sea coast; rivers of the Azov Sea coast 13 sub-basins are allocated in four river basins district. The water management zoning is described - the division of hydrographic units into water management areas, which is carried out for the development of water management balances. In the regions of the river basins in the territory of Ukraine allocated 132 water management areas, 59 of which are located in the Dnipro basin. About 9,000 bodies of surface water allocated for monitoring in Ukraine. Approved zoning is the implementation of the provisions of the EU Water Framework Directive 2000/60 / EC in the management of water resources in Ukraine. Modern hydrographic and water management zoning of the territory of Ukraine approximates the management of water resources of the state to European requirements.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.
