TL;DR: This source of protein (SCP) has been proved a good replacement of other expensive protein sources like fish and soybean meals and can easily replace traditional (plant and animal) protein sources in human, animal as well as fish diets without any detrimental effect.

TL;DR: Lidprotein transport and cholesterol synthesis related mRNA levels were significantly increased in fish fed high fat diets containing BA, and the crude lipid of muscle gradually decreased with increasing supplementation of BA.

TL;DR: The health benefits and the potential application of curcumin and its nanoparticles in fish nutrition are highlighted and future perspectives are offered.

TL;DR: Pellet durability and hardness were overall high for all diets, however, the expansion, sinking velocity and water stability of feed pellets were lower with increased inclusion of BSFL meal and paste.

TL;DR: The machine learning algorithms and techniques adopted in intelligent fish aquaculture in the past five years are expounded, and the application of machine learning is explored in detail, including the information evaluation of fish biomass, the identification and classification of fish, behavioral analysis and prediction of water quality parameters.

TL;DR: Overall the results suggest that insect meals are promising novel protein sources for aquaculture feeds and should be integrated into practical feed formulations.

TL;DR: The results confirmed that GS was effective genetic breeding techniques in resistant breeding against C. irritans in large yellow croaker.

TL;DR: Novel investigations have concluded that Spirulina could be utilized in the treatment of wastewater containing outflow from fish culture activities because of its effectiveness in eliminating heavy metals and metabolising excess feed present in water outflow.

TL;DR: Economic loss due to shrimp diseases in Indian shrimp farming warrants prioritized implementation of better management practices (BMP) and biosecurity protocols along with policy interventions to reduce the direct and indirect losses.

TL;DR: Support is provided to a reliable use of alternative/underexploited protein and lipid sources [(HM) or (PBM)] in developing a new generation of sustainable and healthy trout diets that meet the circular economy principles.

TL;DR: The results showed that the 15% starch levels suppressed the growth, decreased the height and width of villus and number of goblet cell in midgut compared with the other groups.

TL;DR: An on-line survey was carried out among the stakeholders of the shrimp farming sector to evaluate the prospective impact of COVID-19 related lockdown across the shrimp supply chain, estimating an economic loss of 1.50 billion USD to the shrimp aquaculture sector during the current year.

TL;DR: This research studied the use of PNSB use as a protein source for the white leg shrimp and investigated the shrimp's tolerance against Vibrio and ammonia stress.

TL;DR: Dietary inclusion of menthol essential oil significantly enhanced the final body weight, weight gain, and feed conversion ratio (FCR) in a linear and quadratic manner in Nile tilapia.

TL;DR: The goal of this study was to investigate the possible effects of dietary supplementation with autochthonous quorum quenching (QQ) probiotics on growth, digestive enzymes activity, haemato-biochemical responses, gut microbial communities and resistance against Vibrio harveyi in Asian seabass.

TL;DR: Dietary coenzyme Q10 and vitamin C are natural immunostimulants and antioxidants involved in improving the performances and health conditions of aquatic animals and feed intake, amylase, lipase, and protease activities were significantly higher in D5 and D6 groups than the other groups.

TL;DR: Investigation of the possible regulatory roles of yucca extract on the performances of common carp exposed to acute ammonia stress found the growth performance, survival rate, total protein, albumin, and globulin of fish treated with yUcca extract had the highest values.

TL;DR: In this article, an 82 days' feeding trial was conducted to investigate the potentiality of fishmeal replacement with the composite mixture of shrimp hydrolysate and plant proteins in diets for largemouth bass.

TL;DR: The results suggested that the effect of probiotics greatly differed upon the culture condition and the application of multiple strains probiotics had higher efficiency toward immunity than single strain probiotic.

TL;DR: Investigating European consumers' beliefs regarding farmed versus wild fish showed that European consumers believed that wild fish had a higher quality, but that farmed fish were superior in terms of control, price, and availability, suggesting that positive perceptions of products do not necessarily drive higher consumption.

TL;DR: Improving the replacement percentage of fish meal by plant proteins is of value for the aquaculture industry and expressions of inflammation related genes in gut and liver and the levels of LBP, LPS, AST and ALT in serum were significantly increased in uPP group versus control.

TL;DR: The high dietary inclusion of BPM increased the oxidation level in the hepatopancreas of shrimp and impaired the intestinal microvilli, but on the other hand, BPM could increase the height of the mucosal folds, improve the gut microbiota structure and increase the disease resistance of shrimp.

TL;DR: Conclusively, the current study found that the LRP inclusion in a diet at a level of 10 g/kg diet was the optimum for Nile tilapia where this level reduced the diet's cost by 8.5% of the control diet.

TL;DR: Copper sulphate may be a chemotherapeutic for controlling and treating ectoparasites in farmed fish because of its effectiveness and low cost.

TL;DR: This is the first report of V. alginolyticus as a causative pathogen associated with mass summer mortality of the Pacific oysters cultured in China, which provides valuable information for disease surveillance and genetic breeding program to produce oyster strains with high disease resistance.

TL;DR: Results indicated that these three lactic acid bacteria (LAB) supplementary diets especially the L19 produced significant improvement in the digestive enzyme activity (protease, amylase and lipase) in liver, stomach and intestine compared with control.

TL;DR: It is indicated that supplementing the diet with C. butyricum at an appropriate dose can improve the intestinal immunity of common carp by regulating the intestinal microbiota and improving the defence function of the intestinal barrier.

TL;DR: AgNPs adversely affected the performance of Nile tilapia; however, dietary supplementation of 5% PP powder effectively mitigated the oxidative stress and immune suppression resulting from AgNPs exposure.

TL;DR: Overall, appropriate dietary lysine levels could improve the growth performance, reduce the whole-body lipid, promote glycolysis and lipolysis, and cause the upregulation of hormone sensitive lipase, adipose triglyceride lipase and carnitine palmitoyl transferase-1 mRNA levels in the PPAR signaling pathway.

TL;DR: Therapeutic modulation strategies of the gut microbiota have been successfully used in higher vertebrate models; however, these procedures can also be adapted for their application to fish and other aquatic animals.
