Abstract:
... Great Lakes coastal wetlands (GLCWs) provide critical fish habitat. The invasion of GLCWs by hybrid and narrow-leaved cattail, Typha × glauca and Typha angustifolia (hereafter Typha), homogenizes wetlands by out-competing native plant species and producing copious litter. However, the effect of this invasion on fish communities is little known. To measure the effect of Typha on fishes, we establis ...
... Researchers have suggested that cyprinid fishes are less sensitive to chemical stress than comparable fish families, yet few empirically based evaluations of this hypothesis have been conducted. In this study, we developed a generalized linear mixed model in which the no-effect concentrations (NECs; threshold concentration below which no effect on survival is predicted during prolonged exposure) o ...
... The major histocompatibility complex (MHC) is a crucial component of the immune response in vertebrates including teleost fish, which is responsible for the presentation of foreign antigens. In this study, we firstly cloned and identified the gene sequences of MHC IIA and MHC IIB from dojo loach (Misgurnus anguillicaudatus). The full-length cDNA of Ma-MHC IIA and Ma-MHC IIB contained an open readi ...
... Myxozoans are widespread and common endoparasites of fish with complex life cycles, infecting vertebrate and invertebrate hosts. There are two classes: Myxosporea and Malacosporea. To date about 2500 myxosporean species have been described. By comparison, there are only five described malacosporean species. Malacosporean development in the invertebrate hosts (freshwater bryozoans) has been relativ ...
... Analysis of previously published characteristics of the downstream migration of juvenile cyprinids (Cyprinidae) and percids (Percidae) from the Volga and Ivankovskoe, Volgogradskoe, and Tsimlayanskoe reservoirs is presented. In case of river damming, migrations of river fish are modified first of all due to transformation of the hydrophysical and morphological structure of the water course creatin ...
... A novel gene encoding the mitochondrial manganese superoxide dismutase from sterlet Acipenser ruthenus (Ar-MnSOD) was cloned. The full-length cDNA of MnSOD was of 1040 bp with a 672 bp open reading frame encoding 224 amino acids and the deduced amino acid sequence was located in mitochondria. Sequence comparison analysis showed that Ar-MnSOD was highly similar to MnSODs of invertebrates and verteb ...
... Our understanding of how the phylogenetic tree of fishes might be affected by the ongoing extinction risk is poor. This is due to the unavailability of comprehensive DNA data, especially for many African lineages. In addition, the ongoing taxonomic confusion within some lineages, e.g., Cyprinidae, makes it difficult to contribute to the debate on how the fish tree of life might be shaped by extinc ...

Abstract:
... The freshwater populations of native fish species (Ns) have reached critical levels in many parts of the world due to combined habitat deterioration by human interventions and exotic fish species (Es) invasions. These alarming conditions require combined and well-designed interventions for restoring environmental quality and restricting Es invasion. The aim of the study is to propose a method to d ...
... Engraulicypris sardella is an endemic and economically important cyprinid species in Lake Nyasa/Malawi which has recently been infected by the tapeworm Ligula intestinalis. This parasite is known to induce severe pathological and behavioural effects on other cyprinids, including castration, followed by a collapse of infected populations. As a first step to understanding the dynamics between this p ...
... In vertebrates, the T cell receptor (TCR) plays a crucial role in immune system. To date, the roles of fish TCRs in response to pathogen infection are still poorly understood. In the present study, we firstly cloned and identified the TCRα and TCRβ from dojo loach (Misgurnus anguillicaudatus) by RACE approaches. The full-length cDNAs of Ma-TCRα and Ma-TCRβ include an open reading frame (ORF) of 72 ...

Abstract:
... The present article describes the morphology of the skull of Phreatichthys andruzzii Vinciguerra, 1924, blind cave fish from central Somalia. The main findings concern a general flattening of the skull and the loss of several bones (coronomeckelian, prefrontal, supratemporal, intercalar, supraopercle) belonging to the various regions of the head skeleton; but the more important modifications are s ...
... Ligula intestinalis is a tapeworm using copepods and cyprinid fish as intermediate hosts and fish-eating birds as final hosts. Since some parasites can increase their own fitness by manipulating the behavior of the intermediate host, we explored if this parasite affected predator avoidance, swimming activity and depth preference of the fish intermediate host, Engraulicypris sardella. We found that ...
