Description : Pierre Lecefel, ATER en sciences de l'éducation parle d'une recherche qui se déroule à Rivière-Salée, au sein d'un centre de formation pour apprentis (CFA), qui mesure l'impact d'une modalité de formation utilisant l'entretien d'explicitation (Vermersch, 1994) sur le sentiment d'efficacité personnelle (SEP) des formateurs et des apprentis. Le SEP se définit comme « le jugement que porte une personne sur sa capacité d'organiser et d'utiliser les différentes activités inhérentes à la réalisation d'une tâche à exécuter » (Bouffard-Bouchard, Pinard, 1988, p. 411). Si un tel concept, développé dans le cadre de la théorie sociale cognitive (Bandura, 2007), suscite un intérêt croissant chez les chercheurs dans le domaine de l'éducation depuis de nombreuses années, c'est en partie parce que son influence sur les enseignants, sur leurs pratiques pédagogiques ainsi que sur la réussite de leurs élèves est largement démontrée (Skaalvik, Skaalvik, 2007). Dans cette étude, qui suit un paradigme quasi-expérimental, le SEP est utilisé comme moyen de mesure de l'efficacité d'une modalité de formation avec « entretien d'explicitation ». L'objectif est double, d'une part documenter le rôle de la verbalisation dans la construction de l'expérience des apprentis, d'autre part, juger de l'impact d'une approche centrée sur la personne sur le sentiment d'efficacité personnelle du formateur de CFA.

Résumé : We studied the effects of a lactic acid bacterium, Pediococcus acidilactici (strain MA 18/5M, CNCM), as a dietary probiotic on growth performance and some nutritional and microbiological aspects of the shrimp Litopenaeus stylirostris. Experimental shrimp culture was carried out over 10 weeks, using floating cages of 14 m(2) each set in earthen ponds, in a New Caledonia farm affected by "Summer syndrome", a septicaemic vibriosis caused by Vibrio nigripulchritudo. The experiment design testing probiotic-coated pellets against control was replicated in two earthen ponds. High mortalities, characteristic of Summer syndrome, were observed during the first 2 weeks of the trial. The probiotic improved production in the treated cages from both ponds with increases in the survival rate (7% and 15% respectively) and final biomass (8% and 12% respectively). No differences were recorded among treatments on growth performances, but significant lower food conversion ratios were obtained with probiotic treatment. After 5 weeks of rearing, the Hepatosomatic Index and the adjusted dry weight of the digestive gland were significantly increased by 10% and by 9% respectively in shrimps treated with probiotic. In the meantime, the specific activities of alpha amylase and trypsin in the digestive gland showed a significant effect of the probiotic treatment with respective increases by 35% and 55%. The rise in total trypsin activity following morning feeding was also enhanced by the probiotic treatment (P < 0.001). The highest concentration of probiotic (between 10(4)-10(5) CFU g(-1) of fresh gut) in the shrimp gut was obtained 2 h after feeding. The concentration remained high for 4 h after feeding before decreasing until the next meal. Total bacterial counts on Marine agar and TCBS in the gut were significantly lowered by the probiotic treatment over the 10 weeks of the experiment. Additionally, during the first 2 weeks, prevalence and load of V nigripulchritudo strains in haemolymph was lower in animals fed with the probiotic diet. This study demonstrated, under pond conditions, that feeding shrimp with live terrestrial lactic acid bacteria can be an effective treatment for improving shrimp culture affected by vibriosis.

Résumé : Herbivorous (20% vegetable protein, 40% carbohydrate) and carnivorous diets (40% marine animal protein, 20% carbohydrate) were experimentally tested to assess their effect on the energy balance and energetic substrates utilized by postlarvae (PL's /15 days) and juvenile shrimp (3-6 g) of Litopenaeus vannamei. Postlarval stage 60 (PL60, early juveniles) shrimps fed HeD and CaD diets, then late juveniles (3-6 g) acclimated to the same diets were tested for their respective energy partitioning potential. No significant differences (p>0.05) on growth were obtained in early juveniles (mean final wet weight of 0.19 g). However in late juvenile stages a significant difference (p<0.05) in growth rate was observed. In terms of energy partitioning, both early and late juveniles seem to spend more energy in respiratory metabolism than in the elimination of excretion products. A change in feed composition based on quality protein sources induced some modifications on shrimp's activity measured by heat increment. Shrimps fed with an herbivorous diet showed a higher heat increment. Interestingly, the early stages of L vannamei display a remarkable capacity to assimilate a plant protein-based and a high carbohydrate level diet. Such capacity with a stimulation of genes would lead to a good adaptation of juveniles receiving all-plant diets to sustain growth performances up to a marketable size. The implications of these findings for the shrimp farming feeding costs are briefly discussed. (C) 2009 Elsevier B.V. All rights reserved.
