AbstractAbalone is a commercially important mariculture mollusc because of its nutrient‐rich value and extensive market demand. To date, over 95% of the abalone supply has been contributed by farming. Macroalgae are the natural food of abalones. However, the supply of macroalgae is unstable owing to seasonal restrictions. This limits the success of abalone farming. Therefore, formulated diets are crucial for the ongoing expansion and sustainable development of abalone culture. The most important considerations in formulated diets are the nutrient composition and commercially available feed ingredients. This review presents a comprehensive description of the nutrient requirements of abalones and the role that nutrients play in regulating abalone growth and health. The dietary proteins, lipids, carbohydrates, macroalgae sources and feed additives currently used in abalone feeds were subsequently summarised. Additionally, this review also highlights the importance of prioritizing the development of sustainable alternative sources of proteins, carbohydrates and macroalgae to meet the increasing demand for abalone feed. Based on the information provided, future directions in the knowledge of abalone nutrition and feeds are subsequently discussed, which will guide further research towards the development of well‐balanced commercial feeds that enhance feed utilisation and promote abalone growth and health.

This study aimed to evaluate the effects of Bifidobacterium animalis and Bifidobacterium lactis on growth, length-weight relationship and some biological indices of rainbow trout, Oncorhynchus mykiss fry. An iso-nitrogenous (50% crude protein) diet was supplemented with three different concentrations of a mixture of equal quantities of the two strains of Bifidobacterium, namely T1 (1×107CFU/g), T2 (2×107CFU/g), T3 (3×107CFU/g) and a control (without bacteria). A total of 480 trout fries with an initial mean body weight of 0.53±0.19 g were randomly divided into four groups, each with 4 replicates. The fries were distributed into 16 fiberglass tanks (20 L total capacity) each filled with 15 L of water (water exchange rate of 2 L min-1 and permanent aeration) at a density of 2 fries per liter. During the 8-week feeding trial, the mean water temperature was 17.66±1.33°C and that of pH was 7.63±0.08. All fish groups demonstrated positive allometric growth. Trout fries fed with diet T1 recorded significantly higher (P<0.05) gonadosomatic index, specific growth rate and mean weight gain. The highest final mean length (14.12±4.57 cm) was recorded in fry fed with diet T2. The lowest concentration of Bifidobacterium, T1 induced the best growth and it enhanced the biological indices of O. mykiss.

Vibrio species are a significant causative of mass mortality in mariculture worldwide, which can quickly accumulate in live food and transmit into the larval gut. With restrictions on the use of antibiotics in aquaculture, finding a proper solution to reduce the risk of Vibriosis is vital. This study aimed to evaluate the susceptibility of Vibrio harveyi, V. campbellii, V. anguillarum, and V. parahaemolyticus to twenty-six bacterial and yeast strains and use the beneficial ones to enrich live food (Branchiopod, Artemia franciscana, rotifer, Brachionus plicatilis and copepod, Tigriopus japonicus). Thus, a modified disk diffusion method was applied. After a susceptibility assay, the bacteria and yeast beneficial in suppressing the Vibrio species were labeled by fluorescent stain and used to measure the accumulation potential in different live foods. Also, the beneficial bacteria and yeast were used to enrich live foods, and then the count of loaded Vibrio was estimated after 5, 10, 15, and 20 hours by the serial dilution method. From the total bacteria and yeast strains that were used, Candida parapsilosis, Pseudoalteromonas flavipulchra, Lactobacillus sakei, Bacillus natto, and B. amyloliquefaciens inhibited all four Vibrio species. The results of microbial labeling showed that L. sakei in Artemia, C. parapsilosis in rotifers, and V. harveyi in copepods had the highest accumulation rate. The results of the estimation of loaded Vibrio in different live foods also showed that the use of beneficial bacteria and yeast each significantly reduced the count of Vibrio. Application of bacteria and yeast to suppress pathogenic Vibrio maybe a sustainable method for preventing this pathogen from harmfully invading aquaculture and may also aid in reducing the chances of antibiotic resistance in pathogenic Vibrio.

The aim of the present study was to evaluate the effects of diet with different microbial concentrations on the growth and length-weight relationship of Trichopodus trichopterus . For this aim a study was designed with four experimental treatments and the control to evaluate different microbial concentrations on growth and length-weight relationship. The counts of bacteria that were used for dietary supplementation were 1×10 4 , 2×10 4
