background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

Rainbow trout is the most important species of cold water fishes in Iran and the feeding diets which improve the quality and growth of this fish are of great importance. Rainbow trout Oncorhynchus mykiss (n=360) specimens with approximate weight of 2±0.02g were fed with different concentrations of sesame seed in their diet instead of fish meal for 120 days. Feeding diets were prepared in 3 sesa...

this study investigated the inhibitory effects of bacillus licheniformis on g1 and g2 aflatoxins in culture media and kilka fish meal. two concentrations of aflatoxins (8 and 12 ppb for g1 and g2) and (2 and 4 ml from aflatoxins standard per 50g of fish meal) were used in culture media and kilka fish meal respectively. the doses of bacillus were 3 and 4% for this experiment. changes of aflatoxi...

Several feed ingredients have been investigated in an attempt to substitute fishmeal in the diets of fish and livestock. These include both animal protein and plant protein sources. Unfortunately attempts to use these ingredients for complete replacement of the fishmeal component in tilapia diets have not entirely been successful. A major reason is the suboptimal content of essential amino acid...

This study was conducted to investigate the effects of partial replacement of dietary fish meal with soybean meal (SBM) on some blood and serum parameters of Beluga (Huso huso) juveniles. Three isonitrogenic and isoenergetic diets, as SBM1 (Soybean meal protein (SBP): Fishmeal Protein (FP) =1:3), SBM2 (SBP: FP = 2: 3) and SBM3 (SBP: FP =1: 1) were fed to triplicate groups of fish. After 8 weeks...

Tilapia is one of the most important groups of fish for aquaculture with an annual production exceeds two million metric tons. They have been cultured for quite a long time ago. However, their aquaculture production has been developed remarkably during the last few decades due to the increased level of intensification and cultured area. In the past, fish meal was used as a main protein source i...
