A total of 600 PLs with mean initial weight of 0.090± 0.004 g were assigned to five treatments each with three replicates in a completely...
In the first experiment, conducted in a research facility, Litopenaeus vannamei broodstock were fed either a 100% fresh food control treatment (FRE, consisting of frozen squid, oyster, mussel and enriched Artemia biomass in a 2.3:1.4:1.3:1 dry matter ratio) or one of the two treatments in which 50% [dry matter (DM)] of the fresh food was substituted with experimental artificial diets: a dry die...
The effect of environmental enrichment on the behavior and welfare in captivity reptiles freshwater turtles particular, which are popular aquarium pet species, is very little studied compared to other taxa. We carried out a small scale case-study colored object enrichment, with without fish scent, group 15 cooters (Pseudemys sp.) sliders (Trachemys scripta ssp.) display at public aquarium. new ...
Background: Sulfites including sodium metabisulfite (SMB) are commonly used as food preservatives and pharmaceutical products. Despite their worldwide use, there is evidence suggesting their toxicity on human organs and tissues. The purpose of this study was to evaluate the effect of SMB with or without Zingiber officinale (ginger) extract on the rat ovary. Methods: A total of 32 adult, female...
Rainbow trout is one of the most important cultured species in Iran. Despite the progressively increased production of this species during the last decade, there have been many egg quality problems in the hatcheries yet. Thus, in this research we investigated the effects of adding Artemia powder to broodstock diet on Rainbow trout egg quality. Fishes were fed commercial diet for four months, th...

This study was performed to evaluate the effect of feeding with Oregano Vulgare essential oil supplementation on the brain tissue of Koi fish under long-term exposure to naproxen. For this purpose, 135 Koi fish (Mean weight: 1.5 gr; Average length: 6±1 cm) were divided into three groups with three replications. These fish were fed with two diets including a basic diet (BD) and an essential oil ...
The aim of this study was to evaluate the effects of Aloe vera extract (AE) on the immunity responses and hematological parameters in rainbow trout (Oncorhynchus mykiss) fry to develop alternative drug to chemotherapeutics and antibiotics in aquaculture. 1200 rainbow trout (Oncorynchus mykiss) fry weighing 2±0.2 gram were randomly allocated into two treatment groups i...
Abstract In the present study, effects of dietary supplementation low molecular weight sodium alginate on growth, body composition, antioxidant enzymes, digestive and immune response in yellowfin sea bream juvenile ( Acanthopagrus latus ) were investigated. Fish (n=180) divided into 3 groups with replicates received treatments including basal diet without (control treatment), containing 5 g per...
Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...
