TL;DR: These three ammonia removal pathways are reviewed, a set of stoichiometric balanced relationships using half-reaction relationships are developed, and their impact on water quality is discussed.

TL;DR: The counts of Bacillus bacteria in the digestive tract in all treatments were significantly higher than normal, and the effects of a commercial Bacillus probiotic on the digestive enzyme activity, survival and growth of Fenneropenaeus indicus were examined.

TL;DR: In this review, genomic distribution, function, evolution and practical applications of microsatellites are considered, with special emphasis on fish genetics and aquaculture.

TL;DR: A positive relationship between the growth parameters and the protein content of the feeds in this system, and the benefit of natural productivity for production of L. vannamei is confirmed.

TL;DR: Dietary intake of chitosan enhances the innate immune system and survivability of common carp in ponds and the role of ch itosan, chitin and levamisole as immunostimulants with regard to protection against A. hydrophila infection is discussed.

TL;DR: The results showed that gut microbiota were affected by dietary manipulation, and several “new” bacterial species isolated from the alimentary tract of Atlantic cod were identified, suggesting that the GI tract microbiota of fish might not be as simple as believed.

TL;DR: This review covers the main Asian shrimp viruses for which PCR tests and some antibody tests are currently available and it emphasizes work that has been done in Thailand.

TL;DR: Screening results confirm the possible use of seaweeds as a source of antimicrobial compounds or as a health-promoting food for aquaculture and identify seaweeds, which possess activities against fish pathogenic bacteria.

TL;DR: Results are in agreement with the increase of body weight recorded in this study, and FishfedonLAB showed 81% higher body weight in long treated group and 28% in short treated one with respect to control.

TL;DR: The evidence for stronger dominance hierarchies in the 10 kg m − 3 treatment, indicate that low as well as high stocking densities have the potential to adversely affect trout welfare.

TL;DR: The results of this study showed that feeding tilapia with 0.1 and 0.5% Astragalus radix for 1 week enhanced lysozyme activity and for 3 weeks stimulated phagocytosis byphagocytic blood cells, however, respiratory burst activity of phagcytic cells was not increased.

TL;DR: Observations thus far support the contention that nucleotides are conditionally or semi-essential nutrients for fishes, and further exploration of dietary supplementation of nucleotide for application in fish culture is warranted.

TL;DR: The results obtained in this study suggest that the inclusion of G. bursa-pastoris (GP) and U. rigida (UR), up to 10%, can be considered as very interesting ingredients in diets for sea bass juveniles, as no negative consequences on growth performance, nutrient utilization or body composition were observed.

TL;DR: This report discusses and outlines four hierarchical categories of carrying capacity studies: physical, production, ecological, and social carrying capacity, and discusses each in brief and in more detail as this is the level at which knowledge is the most lacking and for which science may make the most advances.

TL;DR: The results suggest that whole-body cortisol is a useful indicator of crowding stress in fasted, adult zebrafish.

TL;DR: Feed intakes of fish fed Diets S0 or S25 were significantly higher than those in fish fed S50, S75, S87.5 or S100, and the effects of supplementation with either crystalline amino acid mixture (CAA) or encapsulated CAA by cellulose acetate phthalate (CAP-AA) to balance Diet S75 were investigated.

TL;DR: Results indicated that the seaweed is suitable as a good candidate for seaweed/fish integrated mariculture for bioremediation and economic diversification.

TL;DR: The diet containing squid hydrolysate might be an alternative to the fish meal diet in order to produce salmon due to a highly balanced dietary amino acid profile.

TL;DR: Effects of soybean meal based diet on growth performance, histology of the intestinal epithelium and on the gut microbiota of juvenile rainbow trout were investigated and diet-related qualitative changes in the microbiota had occurred.

TL;DR: It was hypothesised that the higher average values of firmness in the wild than farmed salmon flesh can in part be attributed to higher concentrations of reducible immature collagen crosslinks, which are thought to be enriched with reducible and non-reducible cross-linked collagen.

TL;DR: Results show that in methionine supplemented diets, FM can be replaced in terms of protein by 25% SE, 50% ET or 60% soy composed of 30% SE and 30% ET without hampering fish performance.

TL;DR: The mass transfer at different aeration rates and the influence of the harvest rate on productivity and biochemical composition were investigated and the potential of the system was evaluated by estimating productivity at full-scale.

TL;DR: β-glucan at different dietary doses was administered to enhance the immunity, growth and survival against Aeromonas hydrophila and Edwardsiella tarda in Labeo rohita fingerlings and this dose resulted in the highest protection in the challenge study.

TL;DR: The changes in hematological parameters of the fish, regardless of the pH and water temperature, indicate ionoregulatory or respiratory disturbances that imply an increase in energy consumption to restore homeostasis instead of other physiological functions such as weight gain and growth.

TL;DR: On the basis of either SGR or FCE, the optimum dietary methionine requirements of juvenile large yellow croaker were estimated to be 1.44% of diet (3.34% of dietary protein) and 1.39% of Diet, respectively, using second-order polynomial regression analysis.

TL;DR: It is suggested that dietary Spirulina has immunostimulatory effects on the innate immune system of carp and the numbers of Aeromonas hydrophila were decreased in the liver and kidney of spirulina-treated fish.

TL;DR: An overview of the development of the South African abalone industry is given and how abalone farming, natural kelp beds and seaweed harvesting are interlinked is analyzed.

TL;DR: The results suggested that vitamin C significantly influenced the immune response and disease resistance of large yellow croaker.

TL;DR: The results indicate that Gracilaria has the potential to remove excess nutrient from coastal areas, and the large-scale cultivation of G. lemaneiformis could be effective to control eutrophication in Chinese coastal waters.

TL;DR: The nitrogen-fixation role of the rice–fish-farming systems in China increased the content of organic matter, total nitrogen and total phosphorus in the soil by 15.6–38.5% and reduces the emission of CH 4 by nearly 30% compared with traditional rice farming.
