TL;DR: The finfish and crustacean aquaculture sector is still highly dependent upon marine capture fisheries for sourcing key dietary nutrient inputs, including fish meal and fish oil, which is particularly strong within compound aquafeeds for farmed carnivorous finfish species and marine shrimp.

TL;DR: This review provides a comprehensive summary of probiotics in aquaculture with special reference to mollusc culture.

TL;DR: From the practical point of view for aquaculture, it is of interest to have microbial bio-flocs that have a high added value and thus are rich in nutrients.

TL;DR: Overall fish growth and production was poor in terms of commercial feasibility and a modified system design that would allow enhanced feed and biofloc utilization is proposed.

TL;DR: Dietary phospholipids increase the efficiency of transport of dietary fatty acids and lipids from the gut to the rest of the body possibly through enhanced lipoprotein synthesis.

TL;DR: This review provides a summary of the status and challenges of probiotic application in aquaculture from the perspective of digestive tract, thereby taking into account the experiences in introducing the preparation, use and safety evaluation of probiotics in Aquaculture.

TL;DR: A wide parabolic regression curve between growth, feed conversion efficiency and temperature indicates high temperature tolerance of Atlantic salmon in this size range studied.

TL;DR: The influence of commercial probiotic, Lactobacillus spp.

TL;DR: It is indicated that bakers’ yeast supplement is promising as an alternative method to antibiotics for disease prevention in tilapia aquaculture, and the optimum level of live bakers' yeast is about 1.0 g per kg diet.

TL;DR: It can be concluded that Astragalus and Lonicera extracts and boron supplementation added to fish feed can act as immunostimulants and enhance the immune response and disease resistance of cultured fish.

TL;DR: This review summarizes those cyanobacterial secondary metabolites that can cause undesirable tastes and odors (odorous metabolites) or are biochemically active (bioactive metabolites) in marine and freshwater, extensive and intensive aquaculture systems.

TL;DR: Evaluating the ability of three lactic acid bacteria isolated from fish to inhibit adhesion of several fish pathogens to host intestinal mucus under in vitro conditions showed that only Lc.

TL;DR: The biochemical components of mainly three copepods from a marine pond system were analysed once a week from spring until late fall, over two years, generating an important base for improvement of live feed enrichment emulsions or formulated feeds used during larval and early juvenile stages in marine fish culture.

TL;DR: Results of this trial indicate that at the level used, supplementation of the diet with FOS or MOS seem to be most positive for salmon production.

TL;DR: After 40 days, the tilapias supplemented with the probiotic showed significantly better final weight and daily weight gain than those fed the basal diet.

TL;DR: Significantly reduced feed intake during the first period and slightly reduced digestibility of 16:0 and starch were identified as possible causes for growth depression, since minor differences in protein or lipid digestibility, feed conversion ratio, and protein and lipid retention were observed.

TL;DR: Three experimental diets in which fish meal was partially or totally replaced by plant protein sources were fed to rainbow trout and gilthead sea bream to study the effects of these diets on digestive enzymes in comparison to fish fed fish meal diets (FM).

TL;DR: This study aimed to evaluate the effect of temperature and dietary starch level on growth performance, nutrient utilisation, whole-body composition and activity of selected hepatic intermediary metabolism enzymes in European sea bass juveniles.

TL;DR: Results indicated that L. vannamei fed at a high level of nutrition, maintained metabolism and oxygen-carrying capacity to meet their energy requirement at low salinity, andLow salinity had stimulated the production of radicals for scavenging, and the activities increase of SOD and CAT for scaventing radicals insured the healthy status of L.vannamee in a certain degree.

TL;DR: Weight gain results showed the freshwater culture system to be viable, with effects from density and survival decreased as density increased with differences between treatments, and the 90 shrimp m − 2 treatment produced organisms with isometric growth.

TL;DR: Electron microscopy of the mid-intestine of developing larvae revealed that MOS-supplemented diets enhanced the height of microvilli while reducing the size of supranuclear vacuoles.

TL;DR: This 75% higher production concurred with a lower inorganic nitrogen content in the water column, a higher THB abundance supplying additional single cell protein to augment the prawn production, and an improved periphyton productivity and quality.

TL;DR: Investigation of fasting effect on flesh composition and antioxidant defenses of market-size large yellow croaker shows that the fasting technique is effective in end product improvement of largeyellow croaker, however, considering flesh protein loss and the subsequent oxidative stress, the fasting techniques should be used with precautions.

TL;DR: The requirement of dietary taurine in yellowtail fed a non-fish meal (FM) diet based on soy protein concentrate (SPC) was examined by a feeding trial and tissue tauri concentration of the NTS group was significantly lower than that of the SPC group.

TL;DR: Histopathological changes indicated that infection of tilapia with GBS produced disease with systemic involvement characterized by multiple necrotic foci in various tissues, establishing that GBS is a pathogen of fish.

TL;DR: A series of GIS models was developed to identify the most suitable areas for scallop culture using multi-criteria evaluation known as weighted linear combination, and about 56% of the total potential area with bottom depths less than 60 m had the higher scores.

TL;DR: It appears that in dentex, partial substitution of fish meal is possible with 25% of soy protein concentrate without affecting growth, which can be improved further by dietary taurine supplementation of 2 g kg − 1 diet.

TL;DR: Fish that received feed supplemented with probiotics showed no evidence of disease after challenge infection, and B. pumilus appears promising as a probiotic for controlling A. hydrophila infection among O. niloticus.

TL;DR: Stocking density at 45 kg/m 3 for 6 weeks did affect the energetic status of sea bass and their sensitivity to a subsequent crowding stressor, and a proper recovery time from stress is recommended to enable sea bass to preserve their physiological status.

TL;DR: It is suggested that ingestion of 1%–2.0% anthraquinone extract supplemented a basal diet has the potential to prevent the pathogenic infection, mitigate the negative effects of crowding stress, and promote growth of the fish.
