Summary: This experiment assessed the effects of replacing fish meal (FM) with soy protein peptide (SPP) at different levels on growth, histology, gene expression related to liver lipid metabolism and intestinal immunity in juvenile pompano Trachinotus ovatus. The results showed that SPP substitution for FM promoted intestinal health and improved liver lipid metabolism without affecting growth performance. The optimal replacement SPP level was determined to be 11.82%.

Summary: White bass is a popular sportfish in the southern United States, but commercial production is currently lacking due to limited information on nutrition and high costs. In this study, the growth and composition of white bass fed different protein ingredients were evaluated. Replacing marine fish meal with soybean meal and poultry by-product meal resulted in similar performance, suggesting that white bass can be fed fish meal-free diets without compromising growth.

Summary: Pacific white shrimp is the most cultivated crustacean globally and plays a crucial role in the international aquatic trade, accounting for 11.96% of the total aquaculture production value in 2020. The growth of the aquafeed industry, particularly the extensive use of fish meal and fish oil, has contributed to the expansion of shrimp production. However, the supply of fish meal has been unstable due to factors like El Nino, resulting in high prices and the need for alternative protein sources.

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 study compared the impact of a high-protein meal replacement (HP-MR) versus a control (CON) breakfast on exercise metabolism. HP-MR resulted in higher fat oxidation, lower carbohydrate oxidation during exercise, reduced hunger sensation, and more favorable changes in metabolic blood markers compared to CON breakfast. The primary findings suggest that HP-MR may be beneficial for exercise performance and metabolic health.

Summary: This study examined the effects of feeding frequency on growth performance, nutrient digestibility, carcass quality, and lipid metabolism in growing-finishing pigs. The results showed that reducing feeding frequency improved feed conversion ratio and had an impact on fat deposition and carcass composition. This study provides a new approach to feeding and management of growing-finishing pigs.

Summary: Understanding the regulation of food intake in fish is crucial for formulating aquafeeds. This study evaluated the short- and mid-term response of European sea bass fed diets with partial and total fishmeal replacement by defatted Tenebrio molitor larvae meal (dTM). The results showed that dTM replacement did not affect food intake regulation in sea bass, but may lead to long-term changes in intermediary metabolism.

Summary: The main goal of this study was to compare the effects of dietary inclusion of poultry fat and mammal fat on European sea bass. It was found that the inclusion of mammal fat led to increased amounts of EPA and DHA in the muscle, while poultry fat had no effect on these fatty acids. This suggests that mammal fat can be a promising source of lipids for aquafeeds.

Summary: This study investigated the effects of induced sustained swimming on various factors in juvenile gilthead seabream, including growth performance, metabolic parameters, external morphology, skeletal muscle fiber characteristics, and immune and metabolic markers. The results showed that induced swimming changed the body shape of seabream, increased the oxygen-carrying capacity and plasma lactate levels, but had no significant effect on growth performance and metabolic rates.

Summary: Mathematical models can be used to estimate the body composition of fish without sacrificing animals. In this study, Nile tilapia body composition data were collected from 138 scientific publications, and predictive models were developed using different combinations of models and calibration methods. The results showed that model predictions are influenced by the type of model, calibration method, and amount of calibration data available. The best predictive models for Nile tilapia body composition were the allometric model and a robust hybrid model, both calibrated assuming multiplicative error.

Summary: This study explores the efficacy of using microalgae as a feed ingredient for fish and validates the results through both a laboratory study and a farm trial. The findings suggest that microalgae can slightly increase the deposition of n-3 fatty acids, EPA, and DHA in Atlantic salmon. Additionally, the pre-treatment of microalgae using extrusion shows positive effects on fish growth, digestibility, and feed utilization efficiency.

Summary: Rising levels of atmospheric CO2 are causing ocean warming and acidification, which have potential negative effects on commercially important fish species. This study examined the effects of ocean acidification (OA) and warming (OW), both individually and combined, on the composition, fitness, and energy budget of juvenile Senegalese sole. The results showed that acidification and warming did not significantly impact the proximate composition and gross energy of the fish. However, OA, OW, and OAW treatments resulted in higher growth rates, metabolic rates, and energy intake compared to control conditions. The study highlights the physiological responses of juvenile Senegalese sole to ocean warming and acidification, emphasizing the importance of understanding the impact of climate change on fisheries.

Summary: Aquaculture intensification is often linked to disease outbreaks, but nutritional approaches, such as algae-derived compounds, can help alleviate the burden caused by diseases. This study evaluated the immunomodulatory activity of an algae blend on farmed seabass's resistance to a bacterial pathogen. The results showed that a 4% inclusion level of the algae blend was the most effective in preventing adhesion and colonization of the pathogen on mucosal tissues, leading to reduced disease progression and mortality.

Summary: This study assessed the effects of replacing fishmeal protein with defatted Tenebrio molitor in European sea bass diets. The results showed that replacing 50% of fishmeal protein with defatted Tenebrio molitor significantly improved feed efficiency without affecting fish growth performance. The nutritional and sensory quality traits of the fish fillets were similar between the control and defatted Tenebrio molitor groups.
