Cyprinidae, etc ; case studies; fish; mortality; pharynx; research; Poland; Show all 7 Subjects
Abstract:
... One of the elements critical to the success of catch-and-release fisheries is the use of appropriate gear that permits releasing fish safely. To date, not all fish species have been the focus of comprehensive studies on this topic, and this applies to cyprinids. Fish from this family are distinct because of their pharyngeal teeth and the particular way they ingest food. We evaluated the impact of ...

Abstract:
... Several morphometric characters with observing general morphology of laboratory-reared larval and juvenile Puntioplites proctozysron (9–40-day-old, 6.8 to 23.4 mm body length, BL) were observed. All myomeres were observable in day 9 flexion larvae. The body proportions tended to become constant in juveniles except for the body depth and upper jaw length that increased continuously. Dorsal and caud ...

Abstract:
... Downstream-migrating fish in rivers tend to follow the main current, and are in danger of swimming through the turbines at run-of-river hydropower plants, possibly causing high mortality rates. To avoid these losses, fish must be prevented from entering the turbines. Most existing vertical bar rack systems (used for turbine protection) however usually do not ensure proper fish protection due to la ...

Abstract:
... Information on the distribution and abundance patterns of trematodes are essential to reveal the ecology of host–parasite interactions. The Western Ghats of India, a biodiversity hotspot, is rich in freshwater fish diversity and endemism. Though there are several studies on various other aspects of fish ecology, studies on their parasitic fauna is meager. The objective of the present study is to e ...
Cyprinidae, etc ; Eocene epoch; Myxocyprinus asiaticus; genome assembly; genomics; paraphyly; pharynx; transcriptome; water; Asia; North America; Show all 11 Subjects
Abstract:
... The Chinese sucker, Myxocyprinus asiaticus (M. asiaticus, Catostomidae, Cypriniformes), is the only living species of Catostomidae in Asia. There are more than 75 species of this family in North America. The fossil record of this group dates back to the early Eocene. As the Chinese sucker is located at the base of the Cyprinoidei phylogeny, this species is also important in clarifying the evolutio ...
... Autophagy and apoptosis play important roles in the occurrence and development of diseases. Largemouth bass virus (LMBV) is a primary agent that causes infectious skin ulcerative syndrome in largemouth bass and threatens the aquaculture of the species. We investigated the relationship between LMBV and autophagy, as well as the effect of autophagy on apoptosis induced by LMBV. Results showed that L ...

Abstract:
... Currently, the existence of Tor species is threatened with extinction and is listed on the IUCN red list due to overfishing, forest destruction, water pollution, fluctuations in water volume, and land conversion. This study aims to fully describe the differences in the osteocranium structure of four Tor species (T. tambroides, T. douronensis, T. tambra, and T. soro) in Indonesia. Visually, the gen ...

Abstract:
... Methods for the use of baited remote underwater video stations (BRUVS) have been tested and refined such that they are now widely used in marine research for assessing fish community structure. There is comparatively less known about the effectiveness of different bait types or bait containers for use with BRUVS in freshwater temperate environments. We conducted a field-based experiment in Lake Op ...
... Intensive aquaculture production systems often encounter infectious viral disease outbreaks causing substantial fish mortalities and associated economic losses. Blue catfish alloherpesvirus (BCAHV) is an Ictalurid herpesvirus with limited information on pathogenesis. To determine the host‐specificity and potential host range of BCAHV, the virus was inoculated onto various fish cell lines belonging ...
Cyprinidae, etc ; Salmo trutta; motivation; salmon; starvation; Black Sea; Show all 6 Subjects
Abstract:
... Changes in the motivational component of rheoreaction (the ratio of rheoreaction types) during starvation in some fish species has been analyzed. The presence of fish motivation to migrate (before starvation) is the major pattern of the future changes in the motivational component of rheoreaction resulting from starvation. All fish of the families Cyprinidae and Salmonidae studied with initially b ...

Abstract:
... The study represents the data on metal content in the body of stoneflies Perla pallida Guerin-Meneville, 1838 (Plecoptera, Perlidae) and in muscles of the fish family Cyprinidae from the small tributaries of the Belaya River (Republic of Adygea, Northwest Caucasus) with ore mineralization of various metals including mercury. It was found that mercury (Hg) concentrations in stoneflies are correspon ...

Abstract:
... The aim of the study was to determine the suitability of Ovopel, which contains an mGnRH analog and metoclopramide (a dopamine inhibitor), for the stimulation of spermiation in the cyprinid fish lake minnow, Eupallasella percnurus (Pallas), which is endangered with extinction in Poland. The hormonal treatment effected an approximate twofold increase in sperm volume with a simultaneous decrease in ...

Abstract:
... Three specimens of Herzensteinia microcephalus (Cyprinidae: Schizothoracinae) were collected from the Chalaiburkun Chu, a headwater of Dri Chu of the southern tributaries of the Yangtze River. The sampling site is located at an altitude of 5,350 m above sea level in the North Slope of the Tanggula Mountain on the Qinghai‐Tibet Plateau. This is a new highest distribution record of cyprinids, perhap ...

Abstract:
... Mahseer (Tor spp., Cyprinidae) are iconic, large‐bodied, migratory freshwater fishes of Asian rivers. Long valued as a food source and serving other societal roles, these fishes are severely threatened by a broad range of interacting and escalating human impacts, including dam construction, water pollution, over‐exploitation, and habitat destruction. Mahseer fishes are therefore beneficial to peop ...

Abstract:
... With the aim of building more compact fishways and adapting them to field conditions to improve their location by fish, it is common to use turning pools, reducing the longitudinal development of the construction. However, depending on their design, turning pools may affect the hydraulic performance of the fishway and consequently the fish passage. To study these phenomena, turning pools in a vert ...

Abstract:
... Virus-encoded tumor necrosis factor receptors (vTNFRs) facilitate viral escape from the host immune response during viral propagation. Cyprinid Herpesvirus-2 (CyHV-2) is a double-stranded DNA virus of alloherpesviridae family that causes great economic losses in the aquaculture industry. The present study identified and characterized a novel TNFR homolog termed ORF4 in CyHV-2. ORF4 was identified ...

... Goldfish is one of the preferred ornamental fish which is highly susceptible to cyprinid herpesvirus-2 (CyHV-2) infection. The present study aimed to analyse immune gene expression in a co-culture of CyHV-2-sensitized goldfish peripheral blood leukocytes (PBLs) with CyHV-2-infected fantail goldfish fin cell lines (FtGF). Goldfish were sensitized with intraperitoneal TCID₅₀ dose (10⁷.⁸±⁰.²⁶/mL) of ...
