Summary: The study indicates the possibility of developing non-fish meal diet for yellowtail with plant protein sources and Schizochytrium sp. by increasing the amount of feed attractant. It is noted that the growth performance of yellowtail was improved with the increase of bonito peptide in the diet, while inversely proportional to the employment rate of algae meal. Further research is required to investigate the essential fatty acid utilization for yellowtail in non-fish meal and non-fish oil diet with microalgae.

Summary: The study found that the optimal dietary lipid level for golden pompano is 107g/kg, and the use of soy protein concentrate can reduce the fish meal level in the diet to 140g/kg. Increasing dietary lipid level does not significantly increase the fish meal replacement level with soy protein concentrate.

Summary: The use of Near-Infrared Spectroscopy (NIRS) can assist in predicting the digestibility of dietary nutrients in Yellowtail Kingfish (YTK) efficiently. The NIRS models developed showed promising results in predicting diet and faecal composition, providing a cost-effective and accurate method for assessing diet apparent digestibility in fish.

Summary: The effect of DPS supplementation on fish meal replacement with SPC for large yellow croaker was evaluated in a feeding trial. The results showed that by replacing 40% and 60% fish meal with SPC and adding 5g/kg DPS, the growth of the fish was promoted. Therefore, DPS supplementation is beneficial for replacing fish meal with SPC in the diet of large yellow croaker.

Summary: Feeding dairy cows a complex concentrate mix designed to match nutrient intake from pasture during late spring may increase milk production. Utilizing a nutrition model to formulate concentrate mixes could achieve similar milk yields, but real-time analysis of pasture is essential for maximizing milk fat and protein yield.

Summary: Soybean meal can be a cost-effective alternative to replace fish meal in aquaculture feed for stinging catfish. This study found that replacing fish meal protein with soybean meal improved the growth, feed utilization, and health condition of the fish. The higher the substitution of fish meal protein by soybean meal, the better the growth and feed efficiency.

Summary: The BfR MEAL Study is the first German total diet study, which reported the first results regarding methylmercury in fish, seafood, and mushrooms. It found that certain fish species had high MeHg concentrations, while mushrooms and mushroom products had lower levels of MeHg. The exposure to MeHg exceeded the tolerable weekly intake recommended by the European Food Safety Authority in adult high consumers. Regional differences in MeHg levels were influenced more by consumption habits than by the MeHg levels in the investigated food.

Summary: The aim of this study was to evaluate the effects of replacing fish meal or soy protein concentrate with wheat gluten on growth performance and feed utilization in Japanese seabass. The results showed that replacing protein from fish meal with wheat gluten had a negative impact on weight gain rate, feed efficiency, and retention of nutrients. However, replacing protein from soy protein concentrate with wheat gluten had no significant effects on growth and feed conversion, but resulted in a decrease in nutrient retention. Overall, wheat gluten is a more effective alternative for replacing protein in soy protein concentrate than fish meal.

Summary: The study found that replacing fish meal with barley protein concentrate (BPC) and wheat gluten meal (WGM) in Caspian brown trout diets can improve growth performance and digestibility. It was also observed that increasing BCP levels in the diets led to a decrease in the activities of protein and aminopeptidase enzymes.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
