TL;DR: The studies carried out on the use of plant products on fish aquaculture and their biological effects on fish such as growth promoter, immunostimulant, antibacterial and anti-parasitic are reviewed.

TL;DR: To determinate the potential of insects as a substitute for fish meal in fish food used in aquaculture, 16 different species of insects were examined, with Diptera b being the most similar group to fish meal.

TL;DR: Probiotics, which are regarded as micro-organisms administered orally leading to health benefits, are used extensively in aquaculture for disease control, notably against bacterial diseases.

TL;DR: The isolation and characterization of bacteria isolated from the hepatopancreas (HP) of shrimp collected from an early mortality outbreak farm in Thailand revealed the possibility of diversity in isolates of V. parahaemolyticus that may cause early mortality in shrimp cultivation ponds.

TL;DR: The results suggest that the intestine of rainbow trout is colonised at an early state, but is guided in new and different directions dependent on the diet type.

TL;DR: Partial analysis of the cost-effectiveness of operations under experimental conditions revealed that the BFT model was more effective than the RAS in tilapia culture.

TL;DR: The effect of biofloc size on the nutritional composition of the flocs and the nitrogen utilization by white shrimp, red tilapia and mussels was investigated.

TL;DR: The results show that the intestinal lesions caused by A .

TL;DR: Overall, the present results indicate that lumpfish is a suitable cold-water option for biological delousing of Atlantic salmon.

TL;DR: A comprehensive overview of the current methods used in research to assess sperm quality is given, in new trends on sperm analysis, and in the use of these tools for the identification of factors enhancing gamete quality.

TL;DR: The results suggest that the host intestinal environment imposes selective pressure on the establishment of microbial communities in shrimp fed diets with different lipid sources, which could affect the composition of the intestinal microbiota of L. vannamei.

TL;DR: This study confirmed the usefulness of S. almeriensis to partially replace fishmeal in practical diets for gilthead sea bream juveniles in a 45-day trial.

TL;DR: The results suggested that the growth of turbot fed diets with 100% SO was significantly lower than the low SO group, which would be related to the up-regulation of fatty acid synthesis-related gene (FAS) and the down- regulation of fatty acids oxidation gene (CPT I) expression.

TL;DR: By formulating on an EAA basis across farmed aquatic species, nutritionists have realized least cost formulation opportunities with the use of CAAs which are now available throughout the world at accessible prices.

TL;DR: Investigation of the effects of commercially available probiotics and prebiotics on growth performances, haematological and immune response and disease resistance in Channa striata fingerlings against the pathogenic bacteria Aeromonas hydrophila found the L. acidophilus , yeast and β-glucan added at a designated dose in the diet improves growth and stimulates the immunity and makes C. striata more resistant to infection by A. hydrophILA.

TL;DR: Edwardsiella tarda is a Gram-negative intracellular pathogen accounting for enormous economic losses in cultured seawater and freshwater fish, and various candidate vaccines have been developed, some of which are very promising for cure of edwardsiellosis.

TL;DR: A broad range of dietary constituents which have been shown to affect immunocompetence and health of aquatic species and how they may influence components of the immune system are reviewed.

TL;DR: The use of phage cocktails of two or three phages increased the efficiency ofphage therapy against Vibrio (more efficient and faster bacterial inactivation), delaying the development of resistance by the bacteria and the use of VIBrio phages with high burst sizes and short lytic cycles also increases the efficiencyof phage therapy.

TL;DR: It seems that organic acids at a 1.

TL;DR: Results indicate that supplementation of the tested protein hydrolysates at approximately 5%, replacing fish meal by 10%, can improve the growth performance, feed utilization, digestibility of dietary protein, innate immunity and disease resistance of juvenile red seabream.

TL;DR: It appears that lycopene can be added up to 400 mg kg − 1 to rainbow trout diets to improve meat quality and modulates oxidative status via activating host defense system at cellular level.

TL;DR: Dietary protein level can be reduced from 35% to 25% without affecting survival, growth, FCR, and physiological status of immune response and antioxidant capability, indicating that the promoted biofloc could contribute to the protein nutrition and physiological health of cultured shrimp.

TL;DR: The nutritional value of soy protein can be improved by enzymatic modification into hydrolysates (SPH), which provide an alternative ingredient for replacing fishmeal protein (FMP) in feed by assessed the feasibility of replacing FMP with SPH in diet for juvenile starry flounder.

TL;DR: The results indicated that the leucocyte count, plasma globulin content and lysozyme activity of fish fed the 5.58 CHO:L diet were significantly significantly higher than the control diet.

TL;DR: Dietary supplemented with H. pluvialis can improve fish growth more than diets supplemented with astaxanthin, and is recommended for the large yellow croaker.

TL;DR: The results showed that MP diet in feed led to reduced mortalities and significantly improved survival, weight gain and feed conversion ratio for treated groups over the control.

TL;DR: In the present study, randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) fingerprinting were used to screen pooled and individual DNA samples from XX, XY, and YY fish for sex-linked markers.

TL;DR: The aim of this study was to describe the epidemiological features of the Hawkesbury outbreak via a formal investigation conducted in real time and comprised an assessment of stock levels, past oyster acquisitions and a trace forward investigation to identify stock at greatest risk due to transfers of oysters.

TL;DR: Dietary VC and VE supplementation could maintain normal growth and health condition of juvenile Japanese flounder fed OFO, however, high doses of both vitamin supplements induced fish lipid peroxidation under oxidative stress condition.

TL;DR: It is demonstrated that rainbow trout fry are more susceptible to oxidative stress induced by dietary oxidized lipid than rainbow trout fingerlings, possibly due to delayed response or lack of complete development of endogenous antioxidant defense system.
