Résumé :
AbstractObjective:Aquaculture is one of the fastest-growing food production sectors in many low-income and food-deficit countries with aquatic ecozones. Yet its specific impact on nutrition and livelihood in local communities, where commercial and/or export-orientated aquaculture activities are developed, is largely unknown.Design:The present narrative and argumentative review aims to provide an overview of our current understanding of the connections between aquaculture agroecosystems, local and national fish production, fish consumption patterns and nutrition and health outcomes.Results:The agroecological dynamic in a coastal-estuarine zone, where the aquatic environment ranges from fully saline to freshwater, is complex, with seasonal and annual fluctuations in freshwater supply creating a variable salinity gradient which impacts on aquatic food production and on food production more generally. The local communities living in these dynamic aquatic ecozones are vulnerable to poverty, poor diet and health, while these ecosystems produce highly valuable and nutritious aquatic foods. Policies addressing the specific challenges of risk management of these communities are limited by the sectoral separation of aquatic food production – the fisheries and aquaculture sector, the broader food sector – and public health institutions.Conclusions:Here we provide an argument for the integration of these factors to improve aquaculture value chains to better address the nutritional challenges in Bangladesh.

Résumé :
Aquaculture is a rapidly expanding and extremely diverse form of animal production. Aquaculture takes place in systems that cover an enormous range of levels of intensification from extensively managed low input static ponds to super-intensive high exchange rate silos with liquid oxygen injection. Appropriate nutritional strategies are required for each level of intensification.

Texte intégral
Résumé :
Ce travail de thèse a eu pour objectif de tester pour la première fois le concept de programmation nutritionnelle chez la crevette Litopaneus vannamei. La première question était de savoir à quel moment le stimulus précoce devait se faire lors du développement de la crevette. Dans ce but, nous avons déterminé deux fenêtres de développement (stades protozoea et post-larvae) pendant lesquelles la plasticité moléculaire pour le métabolisme semblait optimale (publication n°1). La deuxième question portait sur le choix du stimulus environnemental que nous voulions utiliser. Nous avons pris comme stimulus nutritionnel la restriction de la prise alimentaire (restriction énergétique) sachant que ce stimulus pouvait avoir des impacts forts sur le métabolisme de l’adulte chez de nombreuses espèces animales. Nous avons pu démontrer qu’une restriction alimentaire de 40 % (40% de baisse de quantité d’aliment distribuée) dans la phase protozoe (4 jours) et de 70% dans la phase post-larvae (3 jours) était réalisable sans que cela n’induise de baisse de survie et de pertes de performances de croissance des animaux. La restriction alimentaire au stade protozoe n’a pas permis d’observer à long terme des modifications des performances de croissance et du métabolisme (au niveau moléculaire) (publication n°3). Par contre, la restriction alimentaire au stade post-larvae a été un succès concernant la programmation : les performances de croissance, l’utilisation des aliments (avec différents ratios de protéines/glucides) et le métabolisme (au niveau moléculaire) ont été (positivement) affectés par le stimulus précoce chez les animaux juvéniles (publication n°2). Nos travaux originaux et prometteurs nous permettent donc d’envisager dans le futur des expériences de programmation précoce (via la nutrition ou autres facteurs environnementaux) afin de piloter la nutrition des crevettes en aquaculture
This thesis work aimed to test for the first time the concept of nutritional programming in Litopaneus vannamei shrimp. The first question was when early stimulus should be performed during shrimp development. For this purpose, we determined two developmental windows (protozoea and post-larvae stages) during which the molecular plasticity for the metabolism seemed optimal (publication no. 1). The second question was about choosing the environmental stimulus we wanted to use. We took as nutritional stimulus the feed restriction (energy restriction), reported that this stimulus promotes strong impacts on the metabolism in the adulthood of many species of mammals. We were able to demonstrate that a dietary restriction of 40% (40% reduction in quantity feed allowance than normal) at the protozoea phase (4 days) and 70% in the post-larvae phase (3 days) was suitable without deleterious impacts on survival and growth performance of the animals. The feed restriction at protozoea stage did not show long-term changes in growth performance and metabolism (at the molecular level) (publication no. 3). In contrast, post-larvae the feed restriction was successful for the programming: growth performance, food utilization (with different protein/carbohydrate ratios) and metabolism (at the molecular level) were (positively) affected by the early stimulus during the development (publication no. 2). Our original and promising work allows us to envisage in the future early programming experiments (via nutrition or other environmental factors) to pilot shrimp nutrition in aquaculture

Résumé :
The development of cost-effective culture systems such as sea-cages and nutritionally adequate formulated diets for juveniles is of major importance to the advance of commercial spiny lobster aquaculture. Formulated diets have the potential to improve production performance, but to date fresh mussels have consistently produced better growth than formulated diets in spiny lobsters. Reduced food consumption due to the poor attractiveness of formulated diets has been suggested as one of the reasons for the slow growth. Whether gut physiology, processing and digestion could also impair consumption on formulated diets remains to be investigated. Diet digestibility, in particular the digestion of carbohydrates included in formulated diets, is one particular area that needs further research. The objective of this thesis was to make some significant advances in addressing two major bottlenecks (i.e., rearing system and nutrition) currently constraining the commercial ongrowing of J. edwardsii juveniles. Key findings were the following: Sea-cage culture systems of the right design can provide significant growth advantages over tank culture systems, especially on formulated diets, by addressing some of the dietary inadequacies via supplemental nutrition from biofouling; food consumption on formulated diets is significantly constrained in J. edwardsii juveniles because gut throughput is reduced due to a small foregut capacity (2.5-3%), expansion of the baseline dry formulated diet after ingestion, and slow rates of foregut filling (1-2 h), foregut evacuation (10 h), faecal throughput (>34 h) and appetite revival on the formulated diet (>18 h); an intensified intracellular digestion of the formulated diet in the digestive gland may be responsible for the lengthy appetite revival; improving the digestibility of formulated diets appears to be essential to maximise the amount of nutrient assimilated per meal in J. edwardsii; diet digestibility can be improved significantly by decreasing the starch inclusion level and selecting particularly digestible carbohydrate sources for energy (i.e., dextrin, cooked starch, glycogen, and native wheat starch) and feed binder (i.e., carboxymethyl cellulose). Among the digestible carbohydrate sources identified, native wheat starch and carboxymethyl cellulose appears to be best utilised by J. edwardsii juveniles.

Texte intégral
Résumé :
The biotechnology of production and utilisation of the cyanobacterium Spirulina has been well documented. Research has centred mainly on application in human and animal nutrition, and has been motivated by the high protein, vitamin, fatty acid and growth factor contents. The main obstacle in realising the full potential of this feed source has been the high production costs associated with its mass culture in defined media. The observation of blooms of Spirulina in tannery effluent evaporation ponds in Wellington, South Africa, prompted this investigation into the harvesting, and nutritional and toxicological evaluation of this potentially low-cost production system, with the ultimate aim of using the product in aquaculture rations. An investigation of the chemical gradient along the evaporation cascade showed a positive correlation between the prevailing chemical conditions and the dominant species populations. A standing crop of 9.5 tonnes/ha of Spirulina was found to be present in the latter alkaline ponds, characterised by relatively lower organic and sulphur contents. Initial harvesting of the biomass was achieved by the design, construction and implementation of a small-scale screen harvest, which yielded a 25 kg (dry weight) crop. A scale-up model was then designed, and implemented in a technical scale harvest, yielding a crop of 250 kg (dry weight). Both these harvests utilised the bloom of surface-autoflocculated biomass. Concentrated cell slurries were sun-dried on muslin beds, and milled to a coarse powder. An evaluation of the harvest revealed a chemical content similar to other published reports of defined media cultures, with the exception of the protein and amino acid contents. The observed lower levels of the latter two are almost certainly due to the sun-drying method employed, known to reduce the protein content due to thermal denaturation. Legislation demands the strict toxicological evaluation of new protein sources, and because of the effluent-nature of the growth medium of this source of Spirulina, its viability lies only in the application as an animal feed or supplement. A range of toxicological tests were chosen that were targeted to elucidate the possible toxicological constraints of this effluentgrown source of protein in animal nutrition. The nucleic acid and pesticide contents of the harvested biomass were within the prescribed safety ranges. Atomic absorption showed minimal accumulation of minerals and heavy metals from the effluent. A bioassay with the brine shrimp Anemia salina showed that the biomass contained no toxicologically active water-soluble components. A short term feeding trial with new-born chicks showed that supplementation with Spirulina had no effect on the growth rates and feed conversion ratios of the different feeding groups. Pathological analyses showed that the liver was the only target organ to elicit a change in response to supplementation of the diets with Spirulina. A general decrease in liver weight was noted, with Cu, Ca, Fe and Zn being significantly accumulated. A histopathological examination however, showed no cellular and functional aberration from the control animals. The toxicological analyses gave the preliminary safe go-ahead for the evaluation of effluent-grown Spirulina in aquaculture nutrition. The South African abalone Haliotis midae, and the rainbow trout Oncorhynchus mykiss were chosen as representative species of edible cultured organisms. The technology for the culture of the perlemoen abalone is being established in South Africa, with the main area of research being the development of an artificial diet for high density culture. A 40 day growth trial demonstrated that lower concentrations of Spirulina supplemented to an agar-based fishmeal diet resulted in growth rates and feed conversion ratios similar to the control fishmeal and purified-casein diets, and thus has application potential in the nutrition of this high-cost marine delicacy. The aquaculture technology of freshwater rainbow trout is already well established. An eight week feeding trial with various concentrations of Spirulina showed that this effluent-grown protein source can partially replace fishmeal in semi-purified diets. Fish fed Spirulina did not exhibit decisive manifestations of toxicity, as determined in a histopathological study. In addition, Spirulina supplementation resulted in enhanced colouration of the skin and flesh, which may have implications in the aesthetic marketing of this sought-after table fish. The primary aim of this preliminary investigation thus concerned the determination of the biotechnological potential of this effluent-source of Spirulina. A technology transfer from the economically unfeasible defined-media culture was implemented. This project is ultimately aimed as a contribution towards the treatment of tannery wastewater, by the removal of contaminants from the effluent in the form of organic biomass.

Résumé :
It is confirmed that Mac brachium match r ii contains much lower w3 HUFA levels than marine prawns. For larvae which have a low HUFA profile at stage I. survival and growth vary in relation to dietary linolenic acid which is the precursor of these long chain fatty acids. Diets containing different levels of w6 fatty acids produced large differences in survival and slight differences in growth. Recently hatched larvae utilize saturated and monounsaturated fatty acids for their energy requirements, as PUFA's increase from stage I to stage II, suggesting that larvae are able to chain elongate. Heavier M. n2ank ii females have heavier clutches and higher numbers of eggs. However, female weight does not influence weight per egg, nor the volume of each egg. The length of incubation does not significantly influence the larval survival though a negative trend is observed. The ratio between the weight of the parent female and the weight per egg (Wegg/W) is found to be 0.036 which reflects a poor fecundity. Recently hatched larvae consume microencapsulated feed, but do not survive beyond day 13. However, artificial diets can be fed successfully from stages VI-VII, the best growth occurring at a feeding rate of 8-16mg of microcapsules per litre. For the caridean M. ma br; zi and penaeid a=LtUa m2nQdgn larvae, edge index increases from 641 and 223, respectively, at the beginning of their development to 1847 and 750 at the end, reaching 2817 and 5000 at postlarval metamorphosis. These results confirm the herbivorous, omnivorous and raptorial feeder classification given by Itoh (1970). Recently hatched M. rosenbargii larvae show poor ability to crush their food and rely heavily on their embryonic lipid droplet reserves. Later, they feed on live diets, such as Artamin and rotifers, containing their own enzymes which aid larval digestion. Between stages V and VII, the cardiac foregut becomes muscular, the pyloric filter apparatus is functional, and the hepatopancreas increases rapidly in size. Residence time of food becomes longer in the foregut, but remains the same, and later decreases, in the midget. Survival and growth on artificial feed coincide with these changes, suggesting that larval enzyme production is sufficient to digest and assimilate such diets.

Résumé :
Select antibacterials were evaluated for their potential as shrimp aquaculture drugs. Difloxacin and sarafloxacin were evaluated for palatability, toxocity, and residues with respect to shrimp, after 15 days of feeding medicated diets. The pharmacokinetics and bioavailabilities of sulphadimethoxine (SDM) and ormetoprim (OMP) were also established for shrimp. Reductions (p < 0.05) in difloxacin feed palatability were noted as a function of dose. Total survival and mean survival time (p < 0.05) decreased as a function of dose. Signs of animal stress, i.e., lethargic behavior, was also noted in the highest dose group. Shrimp tissue levels of difloxacin were inconclusive and not readily determined with the current analytical methods for the drug in shrimp. However, indications were that elimination may be rapid, i.e., tissue t1/2 of 11.4 h with peak tissue levels following a standard dose response. Feed palatability was reduced (p < 0.05) as a function of sarafloxacin dose. Lower weight gains in the higher dose groups were also noted. Neither the total survival nor the mean survival time (p < 0.05) were affected by sarafloxacin dose. Feed Conversion Ratio's increased with dose, indicating possible subchronic toxicity. Sarafloxacin elimination was rapid, with a tissue t1/2 of 13.4 h and tissue levels decreased to below detectable limits by day 14 of withdrawal in all treatments. Peak tissue levels followed a standard dose response. The hemolymph concentrations versus time data for both SDM and OMP were fitted well by two compartment models. The SDM:OMP parameter estimates of CLs, Vss, and terminal phase t1/2 were 194:2045 ml/kg*h, 1735:25,442 ml/kg, and 6.9:11.5 h, respectively. Plasma protein binding of SDM and OMP was 5.2% and 12.1%, respectively. The bioavailabilities of SDM:OMP were 30:38%. Peak hemolymph concentration (Cmax) and time (Tmax) of SDM post of single oral dose (210 mg/kg) was 14 ug/ml at 4 h, while OMP (42 mg/kg) Cmax and Tmax was 0.45 ug/ml at 0.67 h. The amount of the available oral dose 2 h post administration of SDM:OMP in the hemolymph, muscle, and hepatopancreas were 6.0:0.5%, 9.3:2.8%, and 2.9:20.2%, respectively. Hemolymph and muscle tissue levels were below detectable limits post 48h for SDM and 24 h for OMP.

Résumé :
Aim/Purpose: This paper addressed the topics of sustainable agronomy, aquaculture, hydroponics and soil monitoring methods that show how to move towards a repairing mode and bioremediation in many locations across the globe. Background: Sixty percent of the world’s major terrestrial ecosystems are being degraded; the human ecological footprint is spreading across the globe. The major human impact on terrestrial ecosystems in the form of depletion of ground water, over grazing of livestock, clearing for agriculture, timber and urban development, soil damage from off road vehicles, hydroelectric dams and reservoirs, and air pollution from urban areas and power plants. The cost to bio remediate is in the trillions. Methodology: AG biotech methodologies and applications Contribution: The paper bridges such gaps and informs about brave entrepreneurs and university and community individuals with innovative ideas and emerging technologies that gain the momentum for funding and monitoring nutrient uptake and toxic removal of harmful chemicals from water, soil, plants and fish for restoration to take place. Such techniques begin to conquer the giant by restoring the wealth to our soils and water, rural and urban farmlands and forests that retain and capture natural capital and ensure that nutrition and value added resources minerals are not lost. Findings: Biomonapp can detect and make recommendations for repairing & making sustainable solutions, many entrepreneurs & academics have pioneered ways to find SUS solutions Recommendations for Practitioners: Read from the articles and books listed in the references of this paper to understand the need for bioremediation. Use Biomonapp to diagnose water, soil & fish problems & find solutions. Attend conferences & seminars about SUS responsibility & phytoremediation Recommendation for Researchers: To investigate the phytoremediation and bioremediation techniques. Applications for Biomonapp for plants, water, soil, & animals to rejuvenate and repair water, soil and urban & rural communities Impact on Society: These ideas give the power back to local people who can learn to enhance their lives not only by foods but the sustainable green jobs that are being created to make sure urban and rural areas truly are sustainable. Future Research: The results of monitoring with biosensors & bio monitoring methods with regards to sustainable bioremediation, renovating, continued SUS responsibility training, continued evidence of repair and protecting natural capital & ecosystem services

Résumé :
Aquaculture is considered as a promising alternative to support the food demands of the everincreasing population. Currently, this sector faces several challenges such as using fishmeal, which is unsustainable and expensive. Therefore, it is necessary to identify an alternative feed component that is sustainable, cost-effective and can provide the essential nutrients required by the fish. In this context, microalgae are considered as a viable source of proteins, lipids, polysaccharides and highvalue products (HVPs) such as essential fatty acids, amino acids and vitamins. They play a vital role in the marine food chain and hence can be easily assimilated by the fish. The current research targeted the isolation, identification and characterization of novel marine microalgae from Qatar coastline to produce aquaculture feed supplement. As the climate poses a number of stress factors, such as high light intensities, temperatures and varying salinities, it is expected that novel microalgae with interesting metabolite profiles can be isolated from the environment for developing aquaculture sector in Qatar. Standard plating methods were used to isolate halophilic strains from field waters. PCR-sequencing was used to identify the novel microalgae, cyanobacteria and diatom isolates. Then a comparative analysis of the growth performance and metabolite content was performed to characterize these strains. Results evidenced that the cyanobacteria strain exhibited the highest biomass productivity of 51.4 mg L-1day-1 whereas the highest lipid content was observed in the novel diatom isolate ranging up to 28.62% and the highest amount of carotenoids was detected in the case of the microalgae. As in conclusion, a rich feed supplement blending the three isolates can be considered as an alternative to fishmeal. As a continuation of this research, the potential strains will be cultivated under various stress to increase their nutritional value.
