Background: Social phobia is a chronic distressing psychological disorder with a huge disease burden which has not been sufficiently addressed. The study aims to ascertain the prevalence and correlates of social phobia and its impact on... more
Electric cable radiates an electromagnetic field. So the fire spread amongst combustible cables can be prevented by the application of fire retardant coatings directly on the cable exterior or the fire threat can be isolated by the... more
Pemilihan ikan kutuk/gabus (Channa striata) dikarenakan potensi akuakultur dari spesies yang ada di Indonesia, belum sepenuhnya dieksploitasi meskipun ikan tersebut memiliki banyak karakteristik yang menguntungkan, terutama harga pasar... more
"Abstract Although dams are a common feature on rivers throughout the world, their effects on diversity, composition, and structure of fish assemblages are often unclear. We used electrified benthic trawls and stable isotope analysis... more
The cichlids of Africa present many challenges to the taxonomist. Diverse systematic problems at three levels in cichlid phylogeny form the subject matter of this dissertation. At the most general level, I summarize current morphological... more
"1. Human activities affect fish assemblages in a variety of ways. Large-scale and long-term disturbances such as in-stream dredging and mining alter habitat and hydrodynamic characteristics within rivers which can, in turn, alter fish... more
We studied the diet of the eastern mosquitofish Gambusia holbrooki with in situ experimental mesocosms located in a shallow lake. Different nutrient concentrations (phosphorus and nitrogen) and fish population densities were tested. Our... more
In order to analyse the intraand interpopulation homogeneity/heterogeneity of the pikeperch (Stizostedion lucioperca), the phenotypic variability of morphological characters was estimated on the basis of a biometric analysis of 31... more
Analizamos las amenazas y acciones de manejo y conservación de los peces de las familias Poeciliidae, Goodeidae y Cyprinidae enlistados en la NOM-059-SEMARNAT-2010. Para ello se elaboraron 39 fichas de información con base en la consulta... more
To examine the effects of climate and anthropogenic impacts on fish growth, we compared growth rates of rainbow trout (Oncorhynchus mykiss) in nine closely located warm-temperate lakes of contrasting morphometry, stratification and mixing... more
The relationship between the instantaneous mortality rate (Z) and the instantaneous change in length-frequency distribution of organisms per unit of animal size (μL) takes the following form: Z = μLk(L∞ − L) + k, where k and L∞ are... more
The inclusion of key environmental covariables in habitat quality models is crucial to improve the ability of indicators to predict the response of aquatic organisms to anthropogenic stress. The sensitivity of the freshwater blenny... more
This study aims to identify large-scale environmental variables that explain the distribution of continental exotic fish across five bioclimatic regions in east Algeria (160,000 km²), North Africa. Fish communities were sampled at 39... more
Fish diversity and distributions in 33 streams of the Amanos Mountains were investigated between December 2002 and November 2003. Some physical and chemical parameters, such as water temperature, dissolved oxygen, electrical conductivity,... more
Treatment of the killifish, Fundulus heteroclitus, with ovine thyrotropin (oTSH) produced elevations in serum thyroxin (T4) that varied seasonally with a strong inverse correlation to environmental photoperiod (P < 0.001). At 20°C, oTSH... more
Les types d'#Utiaritichthys sennaebragai$ ont un corps allongé, et les deux séries de dents du prémaxillaire sont proches mais non accolées. Les specimens rapportés à #Utiaritichthys sennaebragai$ postèrieurement à sa description... more
Elasmobranchs are critical to tourism industries worldwide. In French Polynesia, where ecotourism is the second most important industry, little is known about the spatiotemporal distribution of eagle rays. This study represents the first... more
Man-made lakes have been widely used for hydro-electric power by impounding rivers and streams, supply drinking water and irrigation. Smaller, man-made, water bodies have not received the same degree of attention. Natural water bodies... more
We conducted an ichthyological survey during the dry season of 2006 on the semi-arid islands of Aruba, Bonaire and Curaçao to provide information on species composition, richness and distribution in natural and non-natural aquatic... more
Natural and anthropogenic elemental contamination is widespread in the environment. This is especially true in China, a country with rapid industrial and economic growth. Some metals can be toxic at very low concentrations, rapidly... more
