Beginning 1 mo after spawning, over a period of 9 mo, individuals began to show a variety of signs including egg retention, ocular opaci...

Analysis of the shape properties of fish otolith is one way to identify stocks of different species in the marine environment. Length, width, area, perimeter, form factor, aspect ratio, roundness, circularity, ellipticity and rectangularity analyses of otoliths were undertaken to assess patterns of spatial and temporal stock structure of a wide-ranging fish, the Arabian yellow fin sea bream Aca...

The present study aimed to determine the effects of lucantin red and yellow and also astaxanthin on the growth, hematological and immunological parameters, and coloration of the tiger oscar (Astronotus ocellatus). To this end, 120 fingerlings of tiger oscar were equally and randomly divided into 12 aquariums. The fish were fed with experimental diets for 8 weeks. Treatments included diets conta...

Ectopic lipid accumulation has been observed in fish fed a high-lipid diet. However, no information is available on the mechanism by which dietary lipid levels comprehensively regulate lipid transport, uptake, synthesis and catabolism in fish. Therefore, the present study aimed to gain further insight into how dietary lipids affect lipid deposition in the liver of large yellow croaker(Larimicht...

Yellow perch (YP) are metal tolerant fish that form large populations in many metal-impacted regions across Canada. While they are able to survive and reproduce successfully in environments with water and sediment metal concentrations that are toxic to many invertebrates, perch experience a suite of direct and indirect impacts. YP were studied in a series of Canadian Precambrian Shield lakes ne...
