Aquatic and terrestrial habitats are heterogeneous by nature with respect to sound and light conditions. Fish may extract signals and exploit cues from both ambient modalities and they may also select their sound and light level of preference in free-ranging conditions. In recent decades, human activities in or near water have altered natural soundscapes and caused nocturnal light pollution to ...

We present a user study comparing multiple immersive environments for the performance of a task. We expected them to perform differently but it was not obvious how they would differ. Our analysis aimed to discover the environment in which subjects performed best and the environment they preferred. The task, derived from developmental biology, requires a user interactively to label spheres distr...

Zebrafish are a widely utilised animal model in developmental genetics, and owing to recent advances in our understanding of zebrafish behaviour, their utility as a comparative model in behavioural neuroscience is beginning to be realised. One widely reported behavioural measure is the novel tank-diving assay, which has been often cited as a test of anxiety and stress reactivity. Despite its wi...

Direct numerical simulation of self-propelled swimming of three dimensional bionic fish and fish school in a viscous flow in a tank are investigated. The swimming rule and the profile of 3D fish from previous experimental measurements of living fish are used in the study. A parallel software package for the 3D moving boundary problem is obtained, which combines the adaptive multi-grid finite vo...

this study was designed to determine the effects of dietary replacement of fish oil with canola oil ongrowth performance, feed efficiency of body and economic indices of experimental diets of juvenilecommon carp (cyprinus carpio). during the experiment 270 juvenile fish with an average initialweight of 16.24 ± 0.10g were randomly distributed in 18 well aerated cylindrical polyethylene tanks(15 ...

Methylene blue (MB) is an FDA-grandfathered drug with memory-enhancing effects at low doses, but opposite effects at high doses. We investigated the effects of four MB doses (0.1, 0.5, 5.0, or 10.0 μM) on zebrafish memory retention in the T-maze task. After training fish to swim into a certain arm of the T-maze, the fish were placed into a tank containing one of the four MB doses or a control t...

Caspian kutum fish (Rutilus frisii) wild broodstocks were caught by gillnet during their upstream migration and subjected to short-time confinement stress and their physiological responses have been examined. Thirty fish (average weight of 1217.6 g) were divided into three experimental groups CO (control), OV (ovaprim) and CO+OV (cortisol+ovaprim) and placed into rearing tanks (10 fish tank-1; ...

Anisakiasis is a fish-borne zoonotic disease. A case of intestinal anisakiasis in a woman who had consumed raw marinated anchovies was reported. The intestinal localization resulted in occlusive acute abdomen which required an emergency surgical treatment. The histological examination of the eosinophilic granuloma removed from the resected colon revealed the presence of larval nematodes of the ...
