    Notes: Abstract The growth of 0-group Pleuronectes platessa L. on diets containing plant proteins was examined. Diets were made acceptable to the fish by including in them cod flesh which had been predigested with proteolytic enzymes, as well as a proportion of air-dried cod meal. A leaf-protein concentrate was fed at 6 levels ranging from 0 to 63 % of the total dietary protein; B.P. protein concentrate (Toprina) and soyabean meal were examined at a single level — about 45 % of the dietary protein. The remainder of the protein in these diets was animal protein, cod meal or cod flesh. Analysis of the weight gains after a 12 week feeding period and of the growth curves showed that, as the proportion of leaf protein in the diet increased, the growth rate diminished, the effect becoming more pronounced when leaf protein reached 40 % or more of the dietary protein. Growth on the diet containing B.P. protein concentrate was superior to that on the diet containing soyabean meal and was comparable with diets containing low levels of leaf protein. The protein efficiency ratios (PER= g live weight gain/g protein fed) for the different diets showed similar trends to the growth rates. Diets containing 40 % or less of leaf protein and the B.P. protein diet had PERs of 1.4 to 1.5. The soyabean meal diet and diets containing more than 40 % of the protein as leaf protein had PERs of 1.0 or less. The results are considered in the context of production diets for flatfish.

    Notes: Abstract Two organic compounds, diethylstilboestrol a synthetic oestrogen substitute, and cyproheptadine which acts as an appetite stimulant in some mammals, were added separately at 3 different concentrations to diets fed to plaice (Pleuronectes platessa), and their effect on growth examined. Over a 10 week period, low orally-administered diethylstilboestrol (600 μg/kg moist diet) gave rise to increased weight gain, food consumption and food conversion. Higher dietary concentrations of diethylstilboestrol (up to 2400 μg/kg diet) were without effect on these parameters. Cyproheptadine did not stimulate appetite, weight gain or food conversion at any of the levels tested.

    Description / Table of Contents: Summary 1. Group-O plaice,Pleuronectes plattessa L., were grown on partially defined diets containing different levels of protein. 2. The growth rate appeared to increase linearly as the protein content of the diet was increased up to the highest level used (70% of the dry diet). 3. A conversion rate of 1.6 was obtained with diets containing 50% or more of protein. 4. The protein efficiency ratio on all diets was near unity. The maximum value obtained being 1.16 with the 50% protein diet.
    Notes: Extrait Ce travail étudie la croissance de plies,Pleuronectes platessa, soumises à des régimes partiellement définis et examine la relation existant entre la richesse en protéines du régime et la vitesse de croissance. Les groupes-O de plies, individuellement marquées par injection de latex coloré, étaient gardés dans des reservoirs en fibre de verre (approximativement: 90 × 60 × 42,5 de profondeur) sous un système fermé de circulation d'eau de mer. Six groupes de plies recevaient un régime dont la richesse protéique (caséine enrichie d'arginine, cystine, méthionine et tryptophane afin de ressembler à la protéine intégrale de l'oeuf de poule) était différente; respectivement 20, 30, 40, 50, 60 et 70% du poids sec de la nourriture. Ces différents régimes étaient isocaloriques et contenaient 3.7 calories par gramme. L'expérience a été réalisée à 15° C. Le poids initial moyen des poissons utilisés était compris entre 2 et 3 g. La croissance a été presque linéaire avec chaque régime et les vitesses moyennes de croissance par semaine, pendant la durée de l'expérience (28 semaines) ont été de 0.19, 0.22, 0.49, 0.56, 0.73, 0.75 g avec les régimes contenant respectivement de 20% à 70% de protéines. La vitesse de croissance apparait donc augmenter linéairement avec la richesse en protéines du régime jusqu'à la valeur la plus élevée testée. Les taux de conversion (grammes de nourriture sèche nécessaires pour produire une augmentation de poids d'un gramme) ont été de 5.5, 3.5, 2.9, 1.7, 1.6 et 1.6 pour les régimes contenant respectivement de 20% à 70% de protéines. Les rapports d'efficacité protéique (P.E.R. = augmentation — en grammes — du poids vif par gramme de protéines ingeré) ont été de l'ordre de 1.0, la valeur optimum étant de 1.16 pour le régime à 50% protéique. Ces résultats sont discutés et comparés avec ceux trouvés pour le saumon et le poisson chat,Ictalurus punctatus.

    Notes: Abstract Samples of injection-moulded Delrin of a particular known morphology were examined in the scanning electron microscope. It was found that the beam affected the specimen in certain characteristic ways, the raster leaving a permanent imprint on the sample surface. By considering the nature of the irradiation process in the scanning electron microscope the amount and type of beam damage could be quantitatively correlated with the operating variables of the instrument. It is hoped that this will provide the groundwork for similar investigations on other systems. The importance of understanding and controlling beam-induced effects in the interpretation of scanning electron microscope images is clearly brought out by the present study. The nature of the beam damage bears a relation to the texture of the sample as inferred by other means. Thus the scanning electron microscope can serve as a device for achieving controlled beam etching in service of structure studies.
