TL;DR: In this review,Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system, with the added value of producing proteinaceous feed in situ.

TL;DR: Simple estimations indicate potential for a 20-fold increase in world aquaculture production, with increased use of selectively bred stocks leads to better utilization of limited resources such as feed, labour, water, and available land and sea areas.

TL;DR: This study shows that the incorporation of HM protein in fish diets is possible, but limited by its low nutritive value.

TL;DR: It is demonstrated that changes in the intestinal microbiome that may contribute to negative health outcomes when diets contain plant meal proteins can be minimized with additional processing of plant ingredients.

TL;DR: A 30-day feeding experiment was conducted to investigate the effects of promoted bioflocs on growth performance, feed utilization, digestive enzyme activity and whole body composition of Litopenaeus vannamei juveniles in zero-water exchange culture tanks.

TL;DR: Garlic led to enhance the immunity by making L. calcarifer more resistant to infection by V. harveyi, and significantly higher serum protein, albumin and globulin levels were evident in treated groups.

TL;DR: The big challenge for the future is to develop more selective breeding programs for existing and new emerging aquaculture species in order to increase the production of this nutritious food source and to improve the efficiency of the use of feed, water, land and labor resources.

TL;DR: Dietary phytogenic supplementation exerted a beneficial feed conversion effect and increased antioxidant protective capacities in the trout fillet at 5 days of refrigerated storage.

TL;DR: It is concluded that well-designed experiments and meta-analyses are needed to fill critical knowledge gaps if sea cucumber mariculture is to expand in the tropics as it has in temperate Asia.

TL;DR: It is indicated that DMM could be a valuable alternative protein and pigmentation ingredient in shrimp feed and showed significantly higher growth rate and lower feed conversion ratio than the shrimp fed the control diet.

TL;DR: It is demonstrated that bioflocs could provide a supplemental source of food protein and stimulate activities of digestive proteinases, both of which made contributions on protein nutrition of cultured shrimp as indicated by improved feed utilization, protein retention and growth performance.

TL;DR: The most promising gut bacteria isolated in the present study with respect to enzyme production and in vitro growth inhibition showed high similarity to Bacillus thuringiensis by 16S rRNA gene sequencing.

TL;DR: It is concluded that DSM supplemented with FS, KM and SM could completely replace fishmeal in the diets for juvenile red sea bream without any adverse effects on fish performance.

TL;DR: The results showed that the koi fed with diets supplemented with a combination of the COS and B. coagulans had the highest final weight, specific growth rate (SGR), total leukocyte count (WBC), respiratory burst activity, phagocytic activity, lysozyme activity, SOD activity, and disease resistance to A. veronii.

TL;DR: It was concluded that bioflocs technology performed well in high-intensive, zero exchange farming systems of M. japonicus, and the performance may be associated with microbial diversity.

TL;DR: Fishmeal can be completely replaced in diets for late stage salmon over 30 g without compromising fish performance or using land animal protein ingredients in feed formulations, and gains decreased as level of fishmeal replacement increased.

TL;DR: It is suggested that a mixture of soy protein concentrate and microbial floc meal can be utilised as a substitute for fishmeal in diets for L. vannamei juveniles.

TL;DR: The implications of increased osmoregulatory demands to crustacean aquaculture is discussed extensively based on recent literature and research conducted in the laboratory, which includes the various factors that may influence osmoreGulatory abilities, the causes leading to reduced productivity at sub-optimal salinities, potential methods that may broaden tolerable salinity ranges and how os moregulation may interact with another important physiological process, i.e. ammonia excretion.

TL;DR: The results of this study show that SBM is an acceptable ingredient to supply 20% of protein in spotted rose snapper diets, but that higher dietary levels reduce fish performance.

TL;DR: It is demonstrated that dietary OFO increased the oxidative stress condition of fish, but supplement of more than 100 mg/kg VE may prevent tissues from lipid oxidation, and improve growth and health of juvenile red sea bream.

TL;DR: Rabbitfish is thus the first marine teleost in which genes encoding Fad and Elovl enzymes, with all the activities required for the production of DHA from C18 PUFA, have been characterised.

TL;DR: It is recommended that macroalgal culture for bioremediation should be considered at wider geographical scales i.e., bay wide at least, because of the wide distribution of nitrogen emanating from fish culture and the need to optimise growth conditions for cultured macroalgae.

TL;DR: The development of cost-effective and growth-promoting diets for Florida pompano (Trachinotus carolinus L.) is necessary for a feasible pompano aquaculture industry in the United States and research efforts to reduce the utilization of marine ingredients in aquatic feeds are needed.

TL;DR: Growth performance, feed conversion, stress-physiological and metabolic parameters were assessed in juvenile yellowtail kingfish grown in pilot-scale RAS and a water pH of 6.58 resulted in mortality and inhibited both growth and FCR due to physiological disruptions to which the fish could not adapt.

TL;DR: Experiments with Pacific oysters suggested that Pseudoalteromonas sp.

TL;DR: The high survival, very fast growth and moderated production rates of pirarucu stocked demonstrate that cages are a viable alternative method to standard ponds for the commercial production of pirrucu, and the economic indicators appear to be attractive, thus pirarUCu cage culture can become a profitable industry.

TL;DR: Results from the present experiment demonstrate the importance of dietary supplementation of both Arg and Gln in improving growth performance, eliciting positive changes to several components of the innate immune system, and also benefiting the intestinal functionality of hybrid striped bass.

TL;DR: The results of this study indicate that U. lactuca and L japonica are optimum seaweeds for use in the culture of the commercially valuable sea cucumber A. japonicus.

TL;DR: The data suggest the dietary n − 3 LC-PUFA requirement of juvenile cobia can be largely satisfied by DHA, and that EPA, if required, is required only in trace amounts.

TL;DR: The EO of O. gratissimum is an effective and safe anesthetic for silver catfish, and its mechanism seems to be related to an interaction with the GABA A -benzodiazepine receptor.
