Disease relevance of Aquaculture

• These results provided direct evidence that related tetracycline resistance-encoding plasmids have disseminated between different Aeromonas species and E. coli and between the human and aquaculture environments in distinct geographical locations [1].
• Onehundred and forty-eight out of onehundred and fifty strains of Vibrio anguillarum isolated from vibriosis in Danish marine aquaculture produced bacterial communication signals, acylated homoserine lactones, eliciting a response in the Agrobacterium tumefaciens (pZLR4) monitoring system [2].
• Acinetobacter (27%) and Brevundimonas (22%) were predominant among the Irish Ot(r) fishfarm isolates, whereas isolates originating from the English aquaculture site almost entirely consisted of Stenotrophomonas maltophilia (86%) exhibiting high frequencies of tolerance to ampicillin and streptomycin [3].
• AIMS: The study was undertaken with the objective of understanding the virulence-associated genes of the CTX and TCP gene clusters in environmental isolates of Vibrio cholerae, an important human pathogen, isolated from the aquaculture environment [4].
• In recent years, erythromycin has received considerable attention for its therapeutic efficacy against some bacterial kidney diseases in aquaculture and, therefore, suitable and sensitive analytical methods to monitor erythromycin residues in fish are required [5].

Psychiatry related information on Aquaculture

• In summary, photoperiod is a key factor in synchronizing locomotor activity and melatonin rhythms in the Senegal sole, whose nocturnal habits should be taken into account for their rearing by aquaculture [6].

High impact information on Aquaculture

• Probiotic bacteria as biological control agents in aquaculture [7].
• Astaxanthin is a high-value carotenoid used as a pigmentation source in fish aquaculture [8].
• Cultivation methods have been developed to produce Haematococcus containing 1.5-3.0% astaxanthin by dry weight, with potential applications as a pigment source in aquaculture, poultry feeds and in the worldwide nutraceutical market [9].
• Sulfadimethoxine is the most important sulfa antimicrobial used in aquaculture to treat bacterial disease in a wide variety of fish [10].
• Tetracycline is a broad-spectrum antibiotic used in humans, animals, and aquaculture; therefore, many bacteria from different ecosystems are exposed to this antibiotic [11].

Chemical compound and disease context of Aquaculture

• There is a dramatic recrudescence of Saprolegnia infections in aquaculture since the use of the toxic organic dye malachite green was banned in 2002 [12].
• Artemia salina are of major importance in the aquaculture industry and they have been proposed as a uniform world-wide test system for toxicity of chemical substances (Vanhaeke et al. 1981) and for studies in developmental toxicology (Sleet and Brendel 1985) [13].
• This study evaluated the efficacy of emamectin benzoate, 0.2% aquaculture premix, against sea lice on Atlantic salmon in eastern Canada. Salmon pens received either emamectin benzoate, orally, in feed at 50 micrograms/kg body weight/day for 7 consecutive days, or the same diet with no added medication [14].

Biological context of Aquaculture

• Distribution of oxytetracycline resistance plasmids between aeromonads in hospital and aquaculture environments: implication of Tn1721 in dissemination of the tetracycline resistance determinant tet A [1].
• This analytical method has been applied to the phthalate transfer study for agricultural recycling of sludges, where phthalate bioavailability has been studied in aquiculture using two types of experiments [15].
• These results suggest that tet(M) and tet(S) genes are present in fish intestinal and seawater bacteria at aquaculture sites and could be an important reservoir of tetracycline resistance genes in the marine environment [16].
• Antibiotic resistance patterns of the strains revealed that they had acquired a relatively higher resistance to oxytetracycline, amoxycillin, ampicillin, novobiocin and polymixin-B, implicating possible use of these antibiotics in the aquaculture systems [17].

Associations of Aquaculture with chemical compounds

• The triphenylmethane dye, malachite green (MG), is used to treat and prevent fungal and parasitic infections in the aquaculture industry [18].
• Nitrate removal in closed-system aquaculture by columnar denitrification [19].
• Cooccurrence of elevated urea levels and dinoflagellate blooms in temperate estuarine aquaculture ponds [20].
• In recent years,the salmon industry has grown significantly in Europe. This study reports on the determination of a wide range of polychlorinated biphenyls (PCBs), organochlorine pesticides, and polybrominated diphenyl ethers (PBDEs) in farmed and wild European Atlantic salmon fish, aquaculture feeds, and fish oils used to supplement the feeds [21].
• Gentian violet (GV) is a triphenylmethane dye antiseptic with potential for illegal use in livestock production, especially aquaculture where the related malachite green has been widely used [22].

Gene context of Aquaculture

• Although the exact function of the HBP is unknown, its high expression in the liver and ovary suggests a role for this molecule in the cumulative efficiency of fish intake of food or lipid transfer; these results can possibly be applied to aquaculture in the near future [23].
• Recent research suggests that the high incidence of males under aquaculture conditions is due to the high water temperature used, and that the effects of temperature would be mediated by an inhibition of aromatase mRNA expression and activity in genotypic females [24].
• The antioxidant properties of LA may make it useful in aquaculture nutrition, but several effects must first be investigated, and we address here plasma free amino acids (FAA) [25].
• GR transcripts have been cloned and characterized in different fish species, but no studies, to date, are available on the quantification of GR in sea bass (Dicentrarchus labrax, L.), although this is one of the most important species in Mediterranean aquaculture [26].
• To our knowledge this is the first study investigating bacterial communities associated with Great Scallop larvae in different aquaculture systems including noncultured components [27].
