The study was conducted in the river system located at Wilmar oil palm plantation Miri, Sarawak. objective of is to determine fish species diversity and composition streams rivers plantations. Fish were sampled using a variety fishing methods, including, scoop nets, cast net, gill nets different mesh sizes (1.0, 1.5, 2.0, 2.5, 3.75 4.0 cm) from 2 7 February 2014. A total 326 individual includin...

Infections of common carp Cyprinus carpio and koi, its coloured morphotypes, with the cyprinid herpesvirus 3 (CyHV-3) can induce severe clinical signs and increased mortality in affected stocks. This may significantly challenge the economic basis of carp farming in Central Europe. To limit virus spread in carp farms, effective disinfection measures for ponds stocked with infected populations ar...

Spring viraemia of carp (SVC) is a fatal viral disease for cyprinid fish, which is caused by spring viraemia of carp virus (SVCV). To date, no SVC outbreak has been reported in China. Between 1998 and 2002, outbreaks of SVC were reported in ornamental and wild fish in Europe and America, imported from multiple sources including China. Based on phylogenetic analysis, the viral strain isolated fr...

Steroidal estrogens, originating principally from human excretion, are likely to play a major role in causing widespread endocrine disruption in wild populations of the roach (Rutilus rutilus), a common cyprinid fish, in rivers contaminated by treated sewage effluents. Given the extent of this problem, risk assessment models are needed to predict the location and severity of endocrine disruptio...

Abstract High reproductive performance is the key attribute of male fitness, especially due to high skew among males most animal species. Males long-lived iteroparous species have opportunities improve upon their previous attempts with increasing age. We collected individual-specific behaviour and age data on a cyprinid fish, asp ( Leuciscus aspius ), from 2015 2019. tested whether changed over...

In the intestine of 10 (n = 18) cyprinid fish species collected from natural waters of Hungary, the author demonstrated oocysts which were shed unsporulated In tapwater, oocysts sporulated within 24 to 48 h In 6 of the fish species, oocysts of 2 sizes were observed Histological examnations proved that, of the morphologically similar oocysts larger ones developed in nodules in size of a pinhead ...

The Cape Fear shiner (Notropis mekistocholas) is a recently described cyprinid species endemic to the Cape Fear River Basin of North Carolina, USA. Only five populations of the fish remain; thus, it is listed as endangered by the U.S. Government. Determining habitat requirements of the Cape Fear shiner, including water quality and physical habitat, is critical to the survival and future restora...
