TL;DR: The value of adding selected strains of Bacillus as probiotic bacteria to control the Vibrio is shown by comparing farms in Indonesia using the same water sources, which contained luminous VIBrio strains, and demonstrates that it is possible to change bacterial species composition and improve prawn production in large water bodies.
719 citations
TL;DR: Nitrogen (N) biogeochemistry of aquaculture ponds is dominated by biological transformations of N added to ponds in the form of inorganic or organic fertilizers and formulated feeds, although cyanobacterial nitrogen fixation and atmospheric deposition are occasionally important.
616 citations
TL;DR: After challenging shrimps with a shrimp pathogen, Vibrio harveyi, by immersion for 10 days, all probiotic treatment groups had 100% survival; whereas the control group had only 26% survival.
538 citations
TL;DR: The most important diseases of cultured penaeid shrimp have had viral or bacterial etiologies, but a few important diseases have fungal and protozoan agents as their cause as mentioned in this paper.
489 citations
TL;DR: Apparent digestibility of protein and availability of minerals in various feed ingredients were determined for coho salmon and rainbow trout using yttrium oxide (Y2O3) as the inert marker and passive feces collection tanks as a fractional net absorption of nutrients from diets.
434 citations
TL;DR: The relationships between semen fertilization capacity and sperm motility, seminal plasma composition and sperm metabolism in the rainbow trout, Oncorhynchus mykiss, is investigated to find out biomarkers for semen quality.
389 citations
TL;DR: Growth rate, feed conversion and digestibilities of nitrogen, fat and energy were lower in the salmon fed the SBM diet than the FM and RO-SBM diets, while they were similar in Salmon fed the RO- SBM and FM diets.
356 citations
TL;DR: G6PD, ME and ACoAC were found to be the key regulatory enzymes in the lipogenic pathway, with G6PD being the main NADPH-generating enzyme.
309 citations
TL;DR: Results indicate that the oral administration of PG to kuruma shrimp enhances the phagocytic activity of the granulocytes and increases the disease resistance of shrimps.
306 citations
TL;DR: Histopathology of affected shrimps showed the hepatopancreas as the target organ of infection where severe inflammatory responses in the intertubular sinuses were seen and elevated luminescent Vibrio counts in the former at 12 days to 3 weeks after initial entry of water.
299 citations
TL;DR: The nitrogen, phosphorus and solids budget have been constructed for water exchange systems and alternative culture systems such as lined ponds, low salinity rearing and recirculation farms are described in relation to their potential for remediating problems within the shrimp culture industry.
TL;DR: The results indicate that cultivated mussels were suitable for marketing from May to December, particularly in Loch Etive, where they remained in good condition during summer and autumn.
TL;DR: In this article, an 86-day winter period, triplicate groups of 20 Atlantic salmon weighing ca. 5 kg were fed a high-energy diet and subsequently starved for 0, 3, 7, 14, 30, 58 and 86 days prior to slaughter.
TL;DR: It was concluded that specific crossing schemes, possibly involving specialised sire and dam lines, may improve growth performance in Nile tilapia, but that this improvement will be quite marginal and should be accompanied by selection within the parent strains.
TL;DR: Results suggest that Bacillus sp.
TL;DR: It is indicated that acute stressors decrease growth of Atlantic salmon parr, with increasing frequency of stress having a more rapid and greater effect.
TL;DR: It is suspected that the low recapture rates and survival of the hatchery-reared salmon smolts were, in part, caused by the handling and transport of the Smolts prior to the release.
TL;DR: It is demonstrated that Atlantic salmon smolts are more responsive to stress than parr and that developmental differences are more important than seasonal changes.
TL;DR: This study suggests that, if palatability of the diet can be improved, 37.5% of protein from fish meal or 15% fish meal in diet for seabass can be replaced by solvent-extracted SBM, extruded full-fat SBM or steamed full- fat SBM.
TL;DR: Dietary phytase supplementation was effective in reducing P load of rainbow trout fed soybean protein concentrate-based diet.
TL;DR: There may be a wide range of Vibrio spp.
TL;DR: In this paper, faecal dry matter content and apparent digestibility coefficients (ADC) of macronutrients were compared using three different methods of faeces collection: stripping, mechanical sieving, and dissection.
TL;DR: The objective of this study was to quantify both the flow of nutrients through representative integrated aquaculture–hydroponics systems and the effects of different quantities of feed nutrient input on changes in nutrient-specific concentrations.
TL;DR: White spot syndrome associated baculovirus (WSBV) DNA was observed only in the gills, cuticular epidermis and hepatopancreas in the freshwater shrimps Macrobrachium sp.
TL;DR: The presence of algae facilitates the onset of hydrolytic functions of cell membranes in larvae reared in seawater with algae, suggesting that the algae acts by triggering digestive enzyme production, at both the pancreatic and intestinal level.
TL;DR: Greater attention is being paid to developing cell lines for prawns, and to the development of molecular probes for the identification of pathogens, which will provide a basis for a more detailed description of the penaeid prawn genome.
TL;DR: Evidence that alterations in ration level, diet composition, photoperiod, and feeding time influence the most intensively-studied fish metabolic hormones, including thyroid hormones, pancreatic hormones, and hormones of the growth hormone–insulin-like growth factor axis is reviewed.
TL;DR: Although starvation produced some changes in white muscle composition, the rather marginal differences in freshness, texture and colour characteristics of raw or cooked fillets when starvation time varied from 0 to 86 days, suggest that starvation is a rather weak tool for changing fillet quality in Atlantic salmon.
TL;DR: The results from this study indicate that exotic shrimp pathogens can be transmitted via imported frozen products.
TL;DR: The growth rates (based on an increase in organic weight) of oysters fed the monospecific diets were correlated to the amounts of protein and carbohydrate they ingested, and the gross biochemical composition of the microalgae grown in semicontinuous culture differed significantly.
