The prevalence of foodborne trematode (FBT) metacercariae was investigated in fish from 2 localities of northern Vietnam in 2004-2005. Freshwater fish (9 species) were collected from local markets in Hanoi City (n=76) and Nam Dinh Province (n=79), and were examined for FBT metacercariae using the artificial digestion technique. Adult flukes were obtained from hamsters experimentally infected wi...

Despite remaining closed for variable periods, intermittently open estuaries provide habitat 20 for estuarine and marine fish species of commercial and recreational value. To better understand how these systems trophically support their fish assemblages, the diets of four valued fish species, namely Acanthopagrus australis, Platycephalus fuscus, Sillago ciliata and Mugil cephalus, were examined...

Hatchery-reared fish are commonly stocked into freshwaters to enhance recreational angling. As these fishes are often of high trophic position and attain relatively large sizes, they potentially interact with functionally similar resident fishes and modify food-web structure. Hatchery-reared barbel Barbus barbus are frequently stocked to enhance riverine cyprinid fish communities in Europe; the...

1. Understanding the ecological factors driving the burden and pathogenicity of parasites is challenging. Indeed, the dynamics of host-parasite interactions is driven by factors organized across nested hierarchical levels (e.g. hosts, localities), and indirect effects are expected owing to interactions between levels. 2. In this study, we combined Bayesian multilevel models, path analyses and a...

Pakistan is a developing with 148 universities and degree awarding institutions including public and private sector. The enrolment as given in the National Educational Policy 2009 was up to 5% only. It reflects greater demands of higher/tertiary education and calls for alternative strategic measures for addressing the issue. An innovative approach was necessary to address the issue of access. T...

Experiments were carried out in nine 64 m ponds at CEPTArIBAMA over a period of 21 Ž . days in order to evaluate the effect of stocking density StD on survival and growth of larvae of matrinxa, Brycon cephalus. The larvae were randomly divided into treatments of 30, 60 and 120 ̃ 2 Ž . larvae m three replicates per treatment and fed three times a day. Samples of larvae were collected at days 0, 7...
