Butylated hydroxytoluene (BHT) is a commonly used antioxidant added to animal/fish feed to limit lipid autoxidation and peroxidation. Although there have been reviews and reports of BHT toxicity in animals, limited information is available with respect to the toxic effects and accumulation of BHT due to oral exposure in aquaculture species. Therefore, 120 days of feeding trial was conducted to evaluate the effects of dietary BHT on the marine fish olive flounder .

Article Synopsis
  • - This study investigated how adding dietary Bacillus subtilis and mannanoligosaccharides (MOS) impacts the growth and immune function of juvenile Japanese eel, finding that certain combinations led to significant improvements in growth metrics compared to control diets.
  • - Fish that were fed diets with B. subtilis and MOS showed enhanced immune responses and better intestinal health, resulting in higher enzymatic activity and protection against bacterial infections compared to those on a control diet.
  • - The findings suggest that a specific dosage of B. subtilis and MOS can synergistically boost growth, immunity, and disease resistance in juvenile eels, marking a promising dietary strategy for aquaculture.

The current experiment was conducted to evaluate and compare the efficacy of two different probiotics Bacillus subtilis WB60 and Lactobacillus plantarum KCTC3928 in diet of Japanese eel, Anguilla japonica. Seven experimental diets were formulated to contain no probiotics (CON), three graded levels of B. subtilis at 10 (BS), 10 (BS), 10 (BS) and L.

This study was carried out to evaluate the dietary threonine requirement by measuring the plasma free threonine and ammonia concentrations in rainbow trout, Oncorhynchus mykiss after dorsal aorta cannulation. A total of 70 fish (average initial weight 506±8.2 g) were randomly distributed into each of the 14 net cages (5 fish/cage).
