Skeletal anomalies are commonplace among farmed fish. The pug-headedness anomaly is an osteological condition that results in the deformation of the maxilla, pre-maxilla, and infraorbital bones. Here, we report the first record of pug-headedness in an isolated population of the critically endangered native Mediterranean trout Salmo trutta L., 1758 complex from Sardinia, Italy. Fin clips were collected for the molecular analyses (D-loop, LDH-C1* locus. and 11 microsatellites). A jaw index (JI) was used to classify jaw deformities. Ratios between the values of morphometric measurements of the head and body length were calculated and plotted against values of body length to identify the ratios that best discriminated between malformed and normal trout. Haplotypes belonging to the AD lineage and the genotype LDH-C1*100/100 were observed in all samples, suggesting high genetic integrity of the population. The analysis of 11 microsatellites revealed that observed heterozygosity was similar to the expected one, suggesting the absence of inbreeding or outbreeding depression. The frequency of occurrence of pug-headedness was 12.5% (two out of 16). One specimen had a strongly blunted forehead and an abnormally short upper jaw, while another had a slightly anomaly asymmetrical jaw. Although sample size was limited, variation in environmental factors during larval development seemed to be the most likely factors to trigger the deformities.

A small isolated population of tesselated snake, Natrix tesselata was found in the Upper Don (Lipetsk Region, Russia). It is the first record of this species in the Central Chernozem Territory of Russia, which is separated from the northern border of the main range by the distance of about 200 km. An isolated population of common frog, Rana temporaria and phenetically peculiar population of fire-bellied toad, Bombina bombina are found here too. Faunistic aspect of new herpetological records is discussed.

Anuran tadpoles are gregarious predators capable of differentiating food items among diverse types of prey via varied feeding and oral structures.  Tadpoles were collected from different study sites in three districts of northern Odisha during three consecutive rainy seasons (from July–October of 2015–2017).  After morphometric measurements (total length and body length), the stomach contents of 75 tadpoles belonging to five different anuran species (Duttaphrynus melanostictus, Euphlyctis cyanophlyctis, Fejervarya orissaensis, Polypedates maculatus and Microhyla ornata) belonging to four families namely Bufonidae, Dicroglossidae, Rhacophoridae and Microhylidae were examined.  The food spectrum of tadpoles included mostly detritus, followed by phytoplankton (represented by 5 classes and 54 genera).  Such studies contribute to the understanding of the natural diets of these anuran species that can assist in developing management strategies for them.  Aquatic habitats must be conserved and maintained so that conservation of anurans can be ensured.

A new record of a marble trout mtDNA haplotype known to be restricted to Adriatic basin (called marmoratus lineage within Salmo trutta complex) has been reported from Eşen Stream in the Aegean Sea basin of southeastern Turkey, based on sequence data of the mitochondrial DNA control region. The results of this study showed a single unique haplotype from this population, called MATR1. Phylogenetic analyses of this haplotype along with other haplotypes belonging to different mitochondrial DNA lineages of the S. trutta complex confirmed the existence of the marmoratus lineage in Turkey, suggesting a possible river capture between the Adriatic and Aegean Sea basins until the last (Würmian) marine regression.

Quarter Horse breed (QH) has been more recently used in sports in Northern Brazil, however it does not have yet biometric evaluation in order to compare to horses from other Brazilian regions, where QH has a larger historic. Therefore, the aim of our study was to assess and present the biometric profile of Quarter horse breed raised and used in sport activities (barrel racing and vaquejada) in the region of Manaus, AM, Brazil. For this purpose, eighty-two (82) QH, adults, were evaluated through photographs analyzed by the ImageJ® 1.46r software. Eight (8) linear morphometric measurements were performed per animal, namely: Withers height (WHe); Croup height (CrH); Codilho height (CoH); Body length (BL; Neck length (NL); Dorsal-lumbar length (DLL); Scapula length (SL) and Head length (HL). Our results were within the racial standard demanded by the Brazilian Quarter Horse Breeders Association, which demonstrates a racial standardization in the region. The animals were classified as having medium size, eumetric. Regarding the average values (in cm), we obtained: WHe of 147.53 (142.76 to 155.33), CrH of 147.38 (141.12 to 154.48), CoH of 83.13 (81.51 of 87.07), BL of 149.15 (147.20 to 152.70), NL of 57.12 (55.2 to 57.3), DLL of 54.94 (52.9 to 57.0) SL of 54.35 (53.4 to 55.20) and HL of 63.70 (62.20 to 64.60). Our findings suggest similarity between the animals of the Quarter Horse breed raised Manaus-AM region with animals from other Brazilian regions. as well as standardization within the required racial parameters. All animals showed good proportions for the barrel racing and vaquejada practices.

Brown Trout Salmo Trutta

This paper presents the data related to morphometric and physiological (hematological) characteristics of brown trout (Salmo trutta) from the Ponor River. This river rises near the village Podrašnica (municipality of Mrkonjić Grad), sinks above the ground and after a while, near the settlement of Krupa na Vrbasu, appears as a source of the Krupa River (tributary of the Vrbas River). Fish sampling was performed during the summer of 2015 and during this period 22 Salmo trutta units were caught (11 females and 11 males). On that occasion, several morphometric (total and standard body length) and hematological traits (Hct-hematocrit, Hb-hemoglobin and MCHC - mean corpuscular hemoglobin concentration), body mass and Fulton’s condition factor were analyzed. The average value for total body length was 18.85 cm and for standard body length it was 16.85 cm; the mean value for body mass was 80.38 g, and for Fulton’s condition factor 1.41. In case of hematological parameters, the average value for Hct was 0.39 l/l, Hb 70.62 g/l and MCHC 180.64 g/l erythrocytes. The estimated parameters can serve as indicators for the condition of these aquatic organisms, and indirectly, the state of their environment.

The study was conducted to know the diversity of Chiropterans as well as their status and morphometric measurements in Jahangirnagar University campus between July, 2014 and April, 2015. Eight species of bats from three families were identified where Common Pipistrelle (Pipistrellus pipistrellus) and Pouch Tomb Bat (Saccolaimus saccolaimus) were recorded for the first time in Bangladesh. A total of 31bat individuals of 8 species were captured during 15 netting nights for morphological studies. Skull preparation was carried out for taking cranial measurements to identify the Pipistrelle species. No roosting colony of Pteropus gigantius was found in the study area but it visits the area only for foraging while the other species roost permanently. The old buildings in the study area provide suitable habitats for a significant number of insectivore bats. Indian Flying Fox (Pteropus gigantius) was the largest (mean head body length 23.33±1.86cm) and Least Pipistrelle (Pipistrellus tenuis) was the smallest (mean head body length 39.45±1.66 mm) species observed from the study area.Bangladesh J.

ABSTRACTWe sequenced a portion of the D-loop region in over 1000 Arctic char (Salvelinus alpinus) samples from 67 locations across Newfoundland and Labrador to assess the extent of secondary contact among the Arctic, Atlantic, and Acadian glacial lineages in Newfoundland and Labrador. Within Labrador, the Arctic and Atlantic lineages were widespread. Two locations (one landlocked and one with access to the sea) also contained individuals of the Acadian lineage, constituting the first record of this lineage in Labrador. Atlantic and Acadian lineage individuals were found in both eastern and western Newfoundland. Multiple sampling locations in Newfoundland and Labrador contained fish of two or more different glacial lineages, implying their introgression. Glacial lineage did not appear to dictate contemporary genetic divergence between the pale and dark morph of char present in Gander Lake, Newfoundland. Both were predominately of the Atlantic lineage, suggesting the potential for their divergence in sympatry. This study reveals Newfoundland and Labrador to be a unique junction of three glacial lineages which have likely hybridized extensively in this region.

Abstract The present study aims to compare the sensory qualities and the degree of acceptance of wild/farmed brown-trout (Salmo trutta) and the farmed rainbow-trout (Onchorynchus mykiss) by a consumer panel. Acceptability regarding attributes appearance, taste, texture, and global appreciation were evaluated on 20 wild brown-trout, 20 farmed brown-trout and 20 farmed rainbow trout by a consumers’ panel formed by 74 elements. Although the panel of consumers equally well accepted all samples, the rainbow trout had classifications slightly higher in all sensory attributes. This tendency was confirmed by internal preference maps performed for each studied attribute. Consumers’ slightly higher preference for farmed fish might indicate that farmed trout could be an alternative to wild brown trout.
