This study was designed to determine the apparent digestibility coefficients of soybean meal, soy protein concentrate (SPC), isolate (SPI), rapeseed meal (RSM), pea (PPC), wheat gluten (WGM) and flour (WF) for olive flounder, Paralichthys olivaceus. A reference diet (RF) formulated meet nutrient requirements flounder with 1% chromic oxide (Cr2O3) as an inert indicator. Test diets were prepared ...

A new grass carp reovirus (GCRV), healthy (HGCRV), was isolated from in 2019. Its complete genome sequence determined and contained 11 dsRNAs with a total size of 23,688 bp 57.2 mol% G+C content, encoding 12 proteins. All segments had conserved 5' 3' termini. Sequence comparisons showed that HGCRV closely related to GCRV-873 (GCRV-I; 69.57–96.71% protein identity) but shared only 22.65–45.85% 2...

Mycobacterium marinum causes a systemic tuberculosis-like disease in a large number of poikilothermic animals and is used as a model for mycobacterial pathogenesis. In the present study, we infected zebra fish (Danio rerio) with different strains of M. marinum to determine the variation in pathogenicity. Depending on the M. marinum isolate, the fish developed an acute or chronic disease. Acute ...

an 8-week feeding experiment was carried out on beluga (huso huso) juvenile to evaluate the effects of different levels of fish oil containing n-3 highly unsaturated fatty acids (n-3 hufas) on fish growth and fatty acid composition. the requirements of beluga juvenile for n-3 hufas were studied by feeding fish diets containing six different levels of n-3 hufas ranging from 1.56 to 17.25% (% of ...

The current study was undertaken in order to assess the risk that different ranaviruses might impose on European sheatfish aquaculture. As the European sheatfish virus (ESV) is a known pathogen causing losses in European sheatfish aquaculture, it was assumed that closely related exotic ranaviruses might also be able to infect European sheatfish and probably cause disease and mortality in this s...

this study was conducted to determine the optimal dietary protein requirement for lemon fin barb hybrid fingerlings. triplicate groups of fish (1.00 ± 0.05 g) were fed twice a day until apparent satiation with five isocaloric (16 kj/g) diets containing varying protein level ranging from 20 to 40% for 60 days. survival was not affected by the dietary protein level. the weight gain and specific g...

In Turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. It is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...
